From 253c488b062e093157f5edaf368c7178553eb326 Mon Sep 17 00:00:00 2001 From: Moe Dashti Date: Sun, 23 Aug 2026 01:53:12 -0700 Subject: [PATCH 01/79] Added Native Streams high-level and detailed design docs. Derives a server-side stream primitive from Temporal's storage invariants: the stream gets its own history-node branch, appends do not schedule workflow tasks, and readers own their cursor. Keeps the CHASM component O(1) so it does not depend on partial reads. --- streaming-detailed-design.md | 563 +++++++++++++++++++++++++++++++++ streaming-high-level-design.md | 248 +++++++++++++++ 2 files changed, 811 insertions(+) create mode 100644 streaming-detailed-design.md create mode 100644 streaming-high-level-design.md diff --git a/streaming-detailed-design.md b/streaming-detailed-design.md new file mode 100644 index 00000000000..fd63d561d69 --- /dev/null +++ b/streaming-detailed-design.md @@ -0,0 +1,563 @@ +# Native Streams: Detailed Design + +| | | +|---|---| +| Status | Draft for review | +| Ticket | [AI-198](https://temporalio.atlassian.net/browse/AI-198) | +| Author | Moe Dashti | +| Date | 2026-08-23 | +| Companion | `streaming-high-level-design.md` | + +This document specifies the implementation.

Wire types + +### 2.1 Item and batch + +```protobuf +// message.proto +message StreamMessage { + temporal.api.common.v1.Payload body = 1; + // Producer-supplied and, later, server-enriched provenance + // (workflow_id, run_id, original_run_id, attempt). Off by default. + map metadata = 2; + string topic = 3; +} + +// One append is one batch, and one batch is one history node. +message StreamMessageBatch { + repeated StreamMessage messages = 1; +} +``` + +`StreamMessageBatch` is what gets serialized into the node blob. The server does not deserialize it on the normal read path; see §4.3 for the one case where it does. + +### 2.2 Component state + +```protobuf +// stream_state.proto +message StreamState { + bytes branch_token = 1; + + // Visibility frontier. Readers never observe an offset at or past this. + int64 head_offset = 2; + // Truncation floor. Offsets below this are gone. + int64 base_offset = 3; + // Chains history nodes; see AppendRawHistoryNodesRequest.PrevTransactionID. + int64 last_txn_id = 4; + + bool closed = 5; + temporal.api.common.v1.Payload close_reason = 6; + + // Bumped on ownership change so a stale producer's write fails. + int64 owner_epoch = 7; + + // producer_id -> last accepted (seq, first_offset).

That is the property that keeps this off the CHASM partial-read critical path. + +### 2.3 Service + +```protobuf +service StreamService { + rpc CreateStream(...) { business_id = "frontend_request.stream_id"; category = API_CATEGORY_STANDARD; } + rpc AddMessages(...) { business_id = "frontend_request.stream_id"; category = API_CATEGORY_STANDARD; } + rpc PollMessages(...) { business_id = "frontend_request.stream_id"; category = API_CATEGORY_LONG_POLL; } + rpc DescribeStream(...) { business_id = "frontend_request.stream_id"; category = API_CATEGORY_STANDARD; } + rpc CloseStream(...) { business_id = "frontend_request.stream_id"; category = API_CATEGORY_STANDARD; } + rpc TruncateStream(...) { business_id = "frontend_request.stream_id"; category = API_CATEGORY_STANDARD; } + rpc DeleteStream(...) { business_id = "frontend_request.stream_id"; category = API_CATEGORY_STANDARD; } +} +``` + +Options follow `chasm/lib/activity/proto/v1/service.proto`. `business_id` drives shard routing; `API_CATEGORY_LONG_POLL` puts `PollMessages` in the right quota bucket. + +--- + +## 3. Storage mapping + +### 3.1 Branch + +Each stream mints one branch at creation: + +```go +branchToken, err := shard.GetExecutionManager().GetHistoryBranchUtil().NewHistoryBranch( + namespaceID, streamID, runID, + treeID, // the stream's CHASM execution RunID + nil, // branchID: generated + nil, // no ancestors + 0, 0, retention, +) +``` + +The OSS implementation (`common/persistence/history_branch_util.go:49`) ignores namespace, workflow, and run, and returns `{TreeId, BranchId, Ancestors}`. Passing them anyway keeps the SaaS override (Walker) able to do whatever it needs. See §11. + +### 3.2 Offset to node ID + +`serializeAppendRawHistoryNodesRequest` rejects `nodeID <= 0` with "eventID cannot be less than 1" (`common/persistence/history_manager.go:429-433`). So: + +``` +nodeID = offset + 1 +``` + +API offsets start at 0. This mapping is internal and must never leak into the wire protocol. + +### 3.3 Append + +```go +persistence.AppendRawHistoryNodesRequest{ + ShardID: shardID, + BranchToken: s.BranchToken, + IsNewBranch: s.HeadOffset == 0, + Info: streamInfo(namespaceID, streamID), + History: blob, // serialized StreamMessageBatch, opaque to the store + NodeID: s.HeadOffset + 1, + PrevTransactionID: s.LastTxnID, + TransactionID: txnID, // from the shard's transaction ID generator +} +``` + +Verified opaque: `AppendRawHistoryNodes` (`history_manager.go:501`) passes `request.History` straight through and only reads `len(.Data)` for size accounting. Nothing parses it. + +`transactionSizeLimit()` caps the blob (`history_manager.go:437-442`), so a batch that exceeds it must be split across nodes before the transition commits. + +### 3.4 Read + +```go +persistence.ReadHistoryBranchRequest{ + ShardID: shardID, + BranchToken: s.BranchToken, + MinEventID: fromOffset + 1, + MaxEventID: s.HeadOffset + 1, // exclusive + PageSize: pageSize, + NextPageToken: token, +} +``` + +`ReadRawHistoryBranch` returns `HistoryEventBlobs []*DataBlob`, `NodeIDs []int64`, and a page token, without parsing. + +### 3.5 The clip invariant + +> **Every read clips to `HeadOffset`. Nothing else is required for correctness.** + +Node append and frontier update are not one atomic store operation, and never were for workflow history either. Cassandra's `execution_store.go:110-126` appends history nodes in a loop and then calls `UpdateWorkflowExecution`; SQL does the same at `sql/execution.go:339`. + +Two failure shapes, both already handled: + +1. **Nodes written, frontier not advanced.** Orphan nodes sit at offsets at or past `HeadOffset`. `MaxEventID` excludes them, so no reader observes them. A retry rewrites the same node IDs with a higher transaction ID. +2. **Duplicate node IDs from a retry.** `filterHistoryNodes` (`history_manager.go:1039-1073`) keeps the highest transaction ID per node ID and drops the rest. The comment at `:1066` states the ordering contract the store provides. + +There is no window in which a reader sees a gap, and no window in which two readers disagree about a prefix. + +--- + +## 4. RPCs + +### 4.1 `AddMessages` + +``` +AddMessages(namespace, stream_id, producer_id?, seq?, expected_offset?, owner_epoch?, messages[]) + -> { first_offset, next_offset, head_offset } +``` + +Handler calls `chasm.UpdateComponent(ctx, ref, (*Stream).AddMessages, req)`. Inside the transition, in this order: + +1. `Closed` -> `FailedPrecondition` with reason `StreamClosed`. +2. **Dedup.** If `producer_id` set and `producers[producer_id].seq >= seq`, return the recorded `first_offset` and `count` without appending. Idempotent retry. +3. **Fence.** If `owner_epoch` supplied and below `state.owner_epoch`, return `FailedPrecondition` with reason `ProducerFenced`. +4. **Compare-and-append.** If `expected_offset` supplied and it differs from `head_offset`, return `AlreadyExists` carrying `head_offset` so the caller can resynchronise. +5. Serialize `StreamMessageBatch`, splitting if over `transactionSizeLimit`. +6. Emit pending log appends (§5) at `nodeID = head_offset + 1`. +7. `head_offset += len(messages)`; `last_txn_id = txnID`; record the producer cursor. + +Acknowledge after the transaction commits. `first_offset` is the offset of the first message; the caller derives per-message offsets by position. + +`producer_id` and `expected_offset` are alternative idempotency mechanisms. `producer_id` suits a retrying activity; `expected_offset` suits a caller that already tracks position. Supplying neither gives at-least-once, which is a valid choice for a caller that does not care. + +### 4.2 `PollMessages` + +``` +PollMessages(namespace, stream_id, from_offset, max_items, max_bytes, wait_new_messages, wait_timeout) + -> { messages[], first_offset, next_offset, closed, close_reason, head_offset } +``` + +1. `from_offset < base_offset` -> `OutOfRange` with reason `Truncated`, carrying `base_offset` so the reader can jump forward rather than fail. +2. `from_offset > head_offset` -> `InvalidArgument`. +3. `from_offset < head_offset`: serve. Tail cache first (§6); on miss, `ReadRawHistoryBranch`. Trim to `max_items` and `max_bytes`. Return. +4. `from_offset == head_offset` and `closed`: return empty with `closed = true`. +5. `from_offset == head_offset`, not closed, `wait_new_messages`: long-poll (§4.4). +6. Otherwise return empty immediately. + +### 4.3 Reading from mid-batch + +A batch is one node, so `from_offset` can land inside one. Two options: + +- **Chosen:** the server deserializes only the boundary batch and drops the leading messages. One batch, bounded by batch size, and only on the first page. +- Rejected: return whole batches and let the reader skip. That leaks framing into the protocol and makes `max_bytes` unenforceable. + +Every other batch on the page stays opaque and is forwarded as-is. + +### 4.4 Long-poll + +```go +chasm.PollComponent(ctx, ref, func(s *Stream, ctx chasm.Context, from int64) (pollOut, bool, error) { + return pollOut{head: s.HeadOffset, closed: s.Closed}, + s.HeadOffset > from || s.Closed, + nil +}, fromOffset) +``` + +The predicate is monotonic, which `chasm.PollComponent` requires (`chasm/engine.go:426-429`). `HeadOffset` only increases and `Closed` never clears, so it holds. + +`PollComponent` subscribes before releasing the execution lease (`service/history/chasm_engine.go:743-765`), which closes the subscribe/notify race that `get_workflow_util.go:136` has to re-read around. + +Timeout uses `contextutil.WithDeadlineBuffer` with per-namespace `stream.longPollTimeout` and `stream.longPollBuffer`, matching `chasm/lib/activity/handler.go:210-215`. On soft timeout, return an empty response with `next_offset = from_offset`, and the client re-polls. That is the established convention and it keeps a slow stream from looking like an error. + +**Long-poll, not gRPC server-streaming.** Frontend runs 24 unary interceptors and 2 streaming ones (`service/frontend/fx.go:285-328`), and `common/authorization/interceptor.go:224` cannot resolve a namespace at stream handshake because there is no request body to read. Server-streaming is the right eventual read API. It needs new auth, rate-limit, and redirection plumbing, and it is not on the path to proving the cost claim. + +--- + +## 5. The CHASM transaction hook + +This is the one framework change, and the only item with an owner outside this project. + +### 5.1 Problem + +A CHASM component cannot contribute append-log batches at transaction close. `ChasmTree` (`service/history/interfaces/chasm_tree.go:19-53`) has no method for it. Without the hook, an append is two persistence calls: `AppendRawHistoryNodes`, then a separate CHASM update to advance the frontier. + +### 5.2 What already works + +`UpdateWorkflowExecutionRequest.UpdateWorkflowEvents` is `[]*WorkflowEvents`, and each entry carries its own `BranchToken`. Multi-branch appends in a single request are structurally supported. `WorkflowEvents.Events` is typed `[]*historypb.HistoryEvent` though, so it cannot carry an opaque blob. + +### 5.3 Change + +Add a sibling list rather than overloading `WorkflowEvents`: + +```go +// common/persistence/data_interfaces.go +type LogAppend struct { + BranchToken []byte + NodeID int64 + PrevTxnID int64 + TxnID int64 + Blob *commonpb.DataBlob + IsNewBranch bool + Info string +} + +type UpdateWorkflowExecutionRequest struct { + // ... existing fields + UpdateLogAppends []*LogAppend + NewLogAppends []*LogAppend +} +``` + +`executionManagerImpl.UpdateWorkflowExecution` (`common/persistence/execution_manager.go:168`) folds these into the same `[]*InternalAppendHistoryNodesRequest` it already builds from `UpdateWorkflowEvents`, reusing `serializeAppendRawHistoryNodesRequest`. + +On the CHASM side, `CloseTransaction` gains a way to surface pending appends: + +```go +// service/history/interfaces/chasm_tree.go +CloseTransaction() (chasm.NodesMutation, []*persistence.LogAppend, error) +``` + +with `MutableStateImpl.closeTransaction` passing them through. A component registers a pending append during its transition via a new `MutableContext` method. + +### 5.4 Fallback + +If the hook slips, both producer paths still work as two persistence calls in the same order, with the clip invariant unchanged. Cost is one extra round trip per batch, which is still far below a signal. Sequence the hook first but do not block Stage 1 on it. + +--- + +## 6. Tail cache + +A shard-local ring per open stream, holding the last N appended blobs keyed by offset. + +- Populated on append, so the producer's own bytes are already in memory. +- Read path checks it before touching persistence, which makes a reader at the tail a memcopy. +- Bounded per stream and in aggregate per shard, evicting oldest first. A miss falls through to `ReadRawHistoryBranch`, so the cache is never load-bearing for correctness. +- Dropped when the shard loses ownership. A new owner rebuilds it from appends. + +This is what makes fan-out cheap. N readers at the tail cost N memcopies rather than N range scans, which is the difference between the 10-subscriber limit and no meaningful limit. + +`service/history/chasm_notifier.go` uses one global mutex and says so in TODOs at lines 16 and 18. Acceptable for a prototype; a real item before fan-out at scale. + +--- + +## 7. Path A: workflow publishes to its own stream + +An attached stream is a subcomponent of the workflow's execution, so it is already on the workflow's shard and inside the workflow's lock. + +New command handled in `RespondWorkflowTaskCompleted`: + +```protobuf +COMMAND_TYPE_ADD_STREAM_MESSAGES + +message AddStreamMessagesCommandAttributes { + string stream_id = 1; // empty = the workflow's default output stream + repeated StreamMessage messages = 2; +} +``` + +Handling goes in `chasm/lib/workflow/` next to the existing command handlers. The handler resolves the attached `Stream` subcomponent and runs the §4.1 transition against it. The appends ride the workflow task's existing commit via §5. + +Cost of publishing: one extra blob in a write that was already happening. No history event, no extra round trip, and the workflow is not rescheduled. + +Publishing to a stream the workflow does not own is not supported by this command. Use `AddMessages`. See §12. + +--- + +## 8. Path C: workflow consumes a stream + +### 8.1 Mechanism + +A workflow subscribes by recording a `ConsumerCursor`. Thereafter, when the server builds a workflow task for that execution, it attaches the pending slice and records the range: + +``` +PollWorkflowTaskQueueResponse.stream_slices: [ + { stream_id, from_offset, to_offset, messages[] } +] +``` + +and one event per task per stream: + +``` +WorkflowStreamConsumed { stream_id, from_offset, to_offset } +``` + +History grows with workflow tasks, not with messages. + +### 8.2 Determinism + +On replay the server reads `[from_offset, to_offset)` from the same branch and attaches the same bytes. This is deterministic because: + +- the log is immutable, so a given offset always holds the same bytes; +- the range is recorded in history, so it does not depend on when replay happens; +- `filterHistoryNodes` resolves duplicate node IDs the same way on every read. + +No timing dependency, so no versioning hazard. + +### 8.3 Truncation interlock + +Replay needs the bytes to still exist. So truncation is bounded: + +``` +effective_base = min(requested_base, min over consumers of consumer.offset) +``` + +`TruncateStream` below a registered consumer cursor is rejected with `FailedPrecondition`. A consumer is deregistered when its workflow closes, which releases the floor. + +This is the one place where a consumer constrains the stream, and it is unavoidable: recording a cursor instead of the data means the data has to outlive the cursor. + +### 8.4 Bounded attachment and the wake exception + +The attached slice is capped by `stream.maxConsumeBytesPerTask`. If `head_offset - cursor` exceeds it, attach a prefix, record only that range, and schedule a follow-up workflow task. + +That is the single intentional exception to "publishing never wakes a workflow". Publishing does not. An **active in-workflow subscription** does, because the workflow asked to be woken. Worth stating explicitly, because it is the property that keeps Path C from silently reintroducing the cost Path B removes. A workflow that does not subscribe is never woken by stream traffic. + +### 8.5 Continue-as-new and reset + +- **Continue-as-new**: the cursor is workflow state, carried in the continue-as-new input. The stream is untouched. Nothing is duplicated or dropped. +- **Reset**: the workflow rewinds; the stream does not. Cursor events before the reset point are intact, so replay works, and the new run re-consumes from the cursor as of that point. Relative to the abandoned run, some messages are delivered twice. That is visible to the application by design, matching the decision that rewinds are the application's concern rather than something the system hides. + +--- + +## 9. Lifecycle + +| Operation | Mechanism | +|---|---| +| Create, standalone | `CreateStream`, or implicitly on first `AddMessages` when the caller opts in | +| Create, attached | Materialized by the server when a stream reference is passed to `StartWorkflow` | +| Close | `CloseStream`, or a pure task fired when the owning execution completes | +| Truncate | `TrimHistoryBranch` plus advancing `base_offset`, bounded by §8.3 | +| Cap | `max_items` / `max_bytes` in `StreamLifecycle` drive automatic truncation | +| Retention | Side-effect task at `close_time + retention`, then `DeleteHistoryBranch` and `chasm.DeleteExecution` | +| Continue-as-new | No handling required; the stream is not in the workflow's history | + +Close seals, it does not delete. A closed stream stays readable through retention, which is what removes the shutdown handshake that Workflow Streams needs today. + +--- + +## 10. Failure analysis + +| Scenario | Behaviour | +|---|---| +| Crash between node append and frontier advance | Orphan nodes at or past `head_offset`, invisible to readers. Retry rewrites the same node IDs; the store keeps the highest transaction ID. | +| Producer retries after a timeout it did not observe | Dedup on `(producer_id, seq)` returns the original `first_offset`. No double append. | +| Two producers race | `expected_offset` mismatch returns `AlreadyExists` with the current head. With `owner_epoch`, the stale producer is fenced outright. | +| Shard failover mid-stream | New owner reloads the component. `owner_epoch` bump fences the old producer. Readers resume from their own offset. The tail cache is rebuilt. | +| Reader disconnects mid-page | No server state to clean up. The reader re-polls from its last offset. | +| Reader polls a truncated range | `OutOfRange` carrying `base_offset`, so the reader can jump forward. | +| Close races an in-flight append | Both serialize through the component transition. Either the append lands before close, or it fails `FailedPrecondition`. | +| Workflow consuming a stream that gets truncated | Prevented by §8.3. | +| Batch exceeds `transactionSizeLimit` | Split across nodes inside the transition, before commit. | + +--- + +## 11. Cross-boundary check: Walker + +OSS `NewHistoryBranch` ignores `namespaceID`, `workflowID`, and `runID`, but the `HistoryBranchUtil` interface accepts them because the SaaS storage layer overrides it. Minting branches whose tree ID is not a workflow run ID is a change to an assumption Walker may rely on. + +This needs a read of `saas-temporal/walker/` and a conversation with that team before this goes beyond prototype. It does not block an OSS prototype, and it is listed here so it is not discovered late. + +--- + +## 12. Explicitly out of scope + +- **Cross-shard publish to a stream the producer does not own, atomic with the producer's own state transition.** Producers use `AddMessages`, which is idempotent by offset and reliable. Two-phase commit or an outbox only becomes necessary if atomicity with the producer's transition is required, and token streaming does not require it. +- **Nexus and cross-namespace.** A layer on top. +- **gRPC server-streaming reads.** See §4.4. +- **A non-durable tier.** Reintroduces the tuning knob the design removes. +- **Server-populated rewind metadata.** The field exists; filling it in is a later opt-in. +- **Cassandra.** See §14. + +--- + +## 13. Configuration + +| Key | Default | Purpose | +|---|---|---| +| `stream.enabled` | false | Per-namespace kill switch | +| `stream.longPollTimeout` | 20s | Matches history long-poll convention | +| `stream.longPollBuffer` | 3s | Deadline buffer | +| `stream.maxBatchBytes` | 2MB | Bounded by `transactionSizeLimit` | +| `stream.maxMessagesPerPoll` | 1000 | Read page bound | +| `stream.maxBytesPerPoll` | 4MB | Read page bound | +| `stream.tailCacheBytesPerStream` | 1MB | Fan-out cache | +| `stream.tailCacheBytesPerShard` | 256MB | Aggregate bound | +| `stream.maxConsumeBytesPerTask` | 1MB | Path C attachment bound | +| `stream.maxSubscribersPerStream` | 0 | 0 = unbounded; present as a safety valve | + +No user-facing batching knob. Batching is the client's choice of how many messages to put in one `AddMessages` call, and server-side coalescing is internal. Removing the tuning knobs is a stated goal of the 1-pager. + +--- + +## 14. Test plan + +**Unit** (`chasm/chasmtest`, in-memory engine): +- Offset assignment across batches, including split batches. +- Dedup by `(producer_id, seq)` returns the original offsets. +- `expected_offset` mismatch returns the current head. +- Epoch fencing rejects a stale producer. +- Close rejects subsequent appends. +- Truncation floor respects registered consumers. +- Mid-batch read trims correctly at every boundary. + +**Functional** (`tests/stream_test.go`, against SQLite and Postgres): +- Produce and consume end to end, single and many subscribers. +- Long-poll wakes on append and returns empty on soft timeout. +- Reader below `base_offset` gets `OutOfRange` with a usable floor. +- Stream stays readable after the owning workflow closes. +- Continue-as-new leaves the stream unaffected. +- Paths A and C using `tests/testcore/taskpoller.go:29`, whose `WorkflowTaskHandler func(task) ([]*commandpb.Command, error)` lets a test emit `AddStreamMessages` and read the attached slice directly. **No SDK fork is needed to prove either path.** + +**Durability:** +- Kill the server mid-append, restart, assert readers see a prefix and never a gap. +- Assert a producer retry after the kill does not double-append. + +**Failover:** +- Force shard movement mid-stream, assert the epoch fence rejects the stale producer and readers resume. + +**Replay (Path C):** +- Run to completion, evict the workflow cache, force replay, assert attached slices are byte-identical. + +--- + +## 15. Benchmark methodology + +Same workload both ways, on SQLite and Postgres. + +Workload: one LLM-shaped producer emitting 40 messages per second of roughly 20 bytes each for 60 seconds, with 1, 5, and 25 concurrent subscribers. + +Baseline: today's Workflow Streams pattern (batched Signals plus a polling Update), reproduced as a functional-test workload. + +Report: +- persistence round trips per message, +- history bytes written per message, +- Actions per message, +- p50 and p99 time from append to reader receipt, +- marginal cost of the Nth subscriber, +- whether 100ms batching holds up, which is the bar the 1-pager sets. + +The benchmark is the deliverable that makes the September 14 decision possible.

Plan is one branch on `temporalio/api` pinned by pseudo-version rather than a local `replace`, so the branch stays buildable by others. `make update-go-api` is the existing path. + +--- + +## 17.

It was written without building on the earlier prototype branches; comparing notes with those is a separate exercise, deliberately left until after this design settles. + +--- + +## 1. Problem + +Interactive agents produce a continuous stream of tokens, tool calls, reasoning traces, and progress updates. Users need to see them as they happen. + +Today the answer is **Workflow Streams** (Public Preview): an Activity batches output into **Signals**, and an app server long-polls the workflow with a `poll_events` **Update**. The developer-facing shape is right. The mechanics are not: + +- Batching intervals sit at seconds, not milliseconds, to amortise per-item overhead. +- Items land in the workflow's Event History, so they count against the 50MB cap, are re-read on every replay, and are duplicated or dropped across continue-as-new. +- `MaximumSignalsPerExecution` defaults to 10000 (`common/dynamicconfig/constants.go:2630`). A token-per-signal stream exhausts that inside one long response. +- At most 10 concurrent subscribers. +- The stream is unreadable once the workflow closes, so producer and consumer have to coordinate a shutdown. +- Cost. Customers describe it as a non-starter, and several run Redis alongside Temporal instead. + +The last point is the commercial one. Streaming is cited in lost and degraded accounts (Replit, Adobe, Dust, Harvey), and competitors market our lack of a stream primitive as a differentiator. + +## 2. First principles + +### 2.1 What Temporal is, mechanically + +Strip away the programming model and Temporal is a sharded, single-writer, fenced state store. Every entity hashes to one history shard, that shard is owned by one history host at a time under `range_id` fencing, and all mutations linearize through that owner. That single serialization point is the whole source of Temporal's consistency. + +Behind that writer sit **two storage shapes**, and they have opposite cost curves: + +| | Mutable state | History nodes | +|---|---|---| +| Access pattern | read-modify-write | append-only | +| Addressing | by entity | by offset, within a branch | +| Cost of a change | proportional to **total size** | proportional to the **delta** | +| Read granularity | whole blob, loaded eagerly | paged range `[min, max)` | +| Practical size bound | yes | none | +| Already has | fork, conditional update | fork, trim, delete, range read, replication | + +Temporal's own Workflow implementation exploits this asymmetry: the events go in the log, and only the summary goes in mutable state. + +### 2.2 What a stream is, mechanically + +An ordered sequence of immutable opaque blobs, written by one logical producer at a time, read concurrently by many readers each holding their own cursor, terminated by a close marker. + +Read that against the table above: + +- A stream is **never** read-modify-write. Nothing mutates an item after it is written. +- A stream is **unbounded**. That is the requirement, not an accident. +- A stream is **not a decision input**. The producer's next action does not depend on any consumer. + +A stream is exactly the append-only log shape, and exactly not the mutable-state shape. + +### 2.3 Where the cost comes from today + +Workflow Streams have no choice but to use the wrong shape, because the only append-only log a user can write to is workflow history, and every append to it schedules a workflow task. Per batch, that buys: + +- a `WorkflowExecutionSignaled` event plus a mutable-state update, +- a `WorkflowTaskScheduled` event plus a transfer-task row, +- a full worker round trip (matching dispatch, `RecordWorkflowTaskStarted` re-taking the workflow lock, replay, `RespondWorkflowTaskCompleted` as another two-write transaction), +- and then a polling Update to get the data back out, which is another state transition. + +None of that is buying durability. It is buying *workflow semantics* for data that has none. + +### 2.4 The three separations + +Each separation removes exactly one cost centre, and each rests on something Temporal already relies on. + +**1. The stream gets its own log, not the workflow's.** + +The history-node store is already documented as decoupled from workflow concepts (`common/persistence/data_interfaces.go:1158`: "V2 regards history events growing as a tree, decoupled from workflow concepts"). `NewHistoryBranch` (`common/persistence/history_branch_util.go:49`) ignores namespace, workflow, and run entirely; a branch token is just `{TreeId, BranchId, Ancestors}`. + +So give each stream its own branch. That alone delivers: no history bloat, no 50MB cap, no continue-as-new entanglement, readable after the workflow closes, unbounded size, and independent retention. + +**2. Appending does not schedule a workflow task.** + +A token is data *produced by* an execution, not a decision input *to* it. Nothing in the workflow's state machine advances because a token arrived. Scheduling a workflow task for it is a category error. + +Removing it removes the transfer-task row and the worker round trip, which is the dominant per-batch cost. + +**3. Reading is not a state transition.** + +The reader's position is the reader's state. If the reader supplies its offset, the server keeps no durable per-subscriber record. Subscriber count stops being a durable-state problem and becomes a memory problem, so the limit of 10 goes away and a poll costs no Actions. + +## 3. The model + +### 3.1 Entity + +A **Stream** is a first-class entity addressed by `(namespace, streamId)`, implemented as a CHASM component. It exists in two arrangements: + +- **Standalone**: its own CHASM execution, routed by `streamId`. Independent of any workflow. +- **Attached**: a subcomponent of a workflow's execution, so it is co-located on that workflow's shard. + +Both are readable and writable by clients over the same API. The difference is only which shard owns it and, therefore, whether the owning workflow can publish to it for free. + +### 3.2 What lives where + +Only the **frontier** needs to be linearized, so only the frontier lives in mutable state: + +``` +Stream (CHASM component; size is O(1) regardless of stream length) + BranchToken its own history-node branch + HeadOffset visibility frontier; readers never see at or past this + BaseOffset truncation floor + LastTxnID node chaining + Closed, CloseReason + OwnerEpoch producer fence + ProducerCursors per-producer dedup, bounded by producer count + Consumers registered in-workflow cursors, bounded + Owner optional execution ref, for lifecycle only +``` + +Payload bytes go to the stream's own branch and never enter the CHASM tree. + +That last sentence is the design's main claim. It means the component does not grow with the stream, there is no segment-index to blow up mutable state, and **there is no dependency on CHASM partial reads** (`OSS-4917` and `OSS-4918`, both still `To Do`). The history-node store already does paged range reads; that is its job. + +### 3.3 Guarantees + +- **Total order** within a stream, by offset. +- **Exactly-once write**: an acknowledged append appears exactly once, under producer retries, shard failover, and concurrent producers. +- **Durable before acknowledged.** No fire-and-forget tier. Durability is the reason to be on Temporal at all. +- **Readers see a prefix.** A reader never sees a gap and never sees an item that a later reader will not see. +- **At-least-once delivery to the reader, made exactly-once by the reader's cursor.** The reader owns its offset, so a duplicate poll is idempotent. + +### 3.4 Why exactly-once needs no new commit protocol + +The write pair here is (append log nodes, then conditionally advance the frontier). That is what workflow history has done for a decade, and the invariant that makes it safe is one line: + +> **Readers clip to `HeadOffset`.** + +A crash between the two steps leaves orphan nodes at offsets at or past `HeadOffset`, which no reader can observe. A producer retry rewrites the same node IDs with a higher transaction ID, and the store's documented larger-`TransactionID`-wins rule resolves it. Nothing is lost, nothing is double-delivered. + +With that invariant in place, exactly-once reduces to two single-field checks inside the conditional update that is already happening: + +- **Producer fence.** `OwnerEpoch`, bumped on ownership change. A stale producer's update fails. +- **Idempotency.** The producer supplies `(producerId, seq)` or an `expectedOffset`. A retry returns the original result instead of appending again. + +This is the design's second claim: getting the shape right removes the need for a two-phase commit and the machinery that goes with it. + +## 4. Access paths + +### 4.1 Path B: off-shard producer + +The common case. LLM tokens come from an Activity calling the model, not from workflow code. + +``` +Activity / client ──AddMessages(streamId, items)──▶ stream's shard + │ + append blob to stream branch + advance HeadOffset + │ +App server ◀──PollMessages(from=N, wait)─────────┘ + ──SSE──▶ browser +``` + +One gRPC hop, one log append, one small conditional update. The workflow is not involved at all: no workflow task, no history event, no worker round trip, no lock on the workflow. + +### 4.2 Path A: the workflow publishes to its own stream + +For application-level progress updates ("planning", "calling search", "writing file"), which Johann's own analysis argues matter more than token streaming once models get fast. + +An attached stream is on the workflow's shard, under the workflow's lock, inside the workflow task's existing commit. A new `AddStreamMessages` command appends to the stream's branch as part of that transaction. + +The marginal cost of publishing is one extra blob in a write that was already happening. Zero history events, zero extra round trips. + +### 4.3 Path C: the workflow consumes a stream + +This is the case the 2026-07-23 discussion recorded as having no proposed solution, and the Bellevue session deferred. The design admits an answer. + +**Record the cursor in history, not the data.** + +The server attaches the pending slice `[cursor, HeadOffset)` to the workflow task response, and writes exactly one event per task: + +``` +WorkflowStreamConsumed { streamId, fromOffset, toOffset } +``` + +On replay the server re-reads the same offset range from the same branch. That is deterministic by construction, because the log is immutable and offset-addressed. Nothing about the replay depends on timing. + +History then grows with **workflow tasks, not with items**. A 50,000-token response consumed across 8 workflow tasks costs 8 small events instead of 50,000 large ones. + +This is the third claim, and it inverts the framing from the July discussion. That discussion looked for ways to make many small workflow tasks cheaper (pipelining). The cheaper move is to make one workflow task carry many items. + +One intentional exception falls out here. Publishing never wakes a workflow. But an *active in-workflow subscription* does: if a subscribed workflow's cursor is behind `HeadOffset` when its task completes, the server schedules another task. That is the workflow asking to be woken, which is a different thing from a producer waking it. + +## 5. Lifecycle + +- **Creation** is explicit for standalone streams, and implicit for attached ones (pass a stream reference to `StartWorkflow` and the server materialises it), so producers and consumers never have to coordinate on who creates it. +- **Close** is explicit, and automatic when the owning execution completes. Close seals the stream; it does not delete it. +- **Retention** works like a workflow's. A closed stream stays readable through retention, then `DeleteHistoryBranch` reclaims it. +- **Truncate** advances `BaseOffset` and calls `TrimHistoryBranch`. A reader below `BaseOffset` gets a distinguishable error carrying `BaseOffset`, so it can jump forward rather than fail. +- **Continue-as-new** needs no handling. The stream is not in the workflow's history, so there is nothing to duplicate or drop. + +## 6. Cost + +Per 100ms batch, steady state. The middle column is what we measure in Stage 0, not an estimate. + +| | Workflow Streams today | This design (Path B) | +|---|---|---| +| gRPC hops | 2, plus a worker round trip | 1 | +| History events written | 2 per signal, plus WFT completion | 0 | +| Log appends | 1, into the workflow's own history | 1, into the stream's branch | +| Mutable-state updates | 2 or more | 1, small and fixed-size | +| Transfer-task rows | 1 | 0 | +| Worker round trips | 1 | 0 | +| Workflow lock acquisitions | 3 or more | 0 | +| Counts against 50MB history | yes | no | +| Hard ceiling | 10000 signals per execution | none | +| Cost of the Nth subscriber | an Update per poll | a memcopy | + +Substantiating this table against a real workload is the point of the prototype. The claim to test is that 100ms batching becomes practical, which is the bar the Native Streams 1-pager sets. + +## 7. Non-goals + +- **Sub-100ms realtime voice.** Different point in the design space; durable-per-item is the wrong trade there. +- **Kafka-scale firehose.** Many modest-volume streams, not few enormous ones. +- **Nexus and cross-namespace.** A layer on top, deliberately later. +- **A non-durable tier for token deltas.** Splitting durable application events from ephemeral deltas reintroduces exactly the tuning knob we are trying to remove. If the cost work lands, the split is unnecessary. +- **Automatic rewind handling.** On workflow retry or reset the stream keeps appending; the rewind surfaces as item metadata. Hiding it from the user would be worse than exposing it. +- **Cross-shard atomic publish** to a stream the producer does not own. Producers use the RPC, which is already idempotent by offset. Two-phase commit only becomes necessary if the publish must be atomic with the *producer's own* state transition, and token streaming does not need that. + +## 8. Dependencies and risks + +**The one framework change.** `ChasmTree` (`service/history/interfaces/chasm_tree.go:19-53`) gives a component no way to contribute append-log batches at transaction close. `UpdateWorkflowExecutionRequest.UpdateWorkflowEvents` is already `[]*WorkflowEvents`, each carrying its own `BranchToken`, so multi-branch appends in one transaction are structurally supported; the tree just cannot reach them. This hook is what makes Paths A and B single-round-trip. It has an owner outside this project (Yichao, CHASM) and should be raised in week one. If it slips, both paths still work as two persistence calls with the same invariant and one extra round trip. + +**Blob framing.** The design assumes the raw history-node paths (`AppendRawHistoryNodes` / `ReadRawHistoryBranch`) treat the blob as opaque. If any surrounding machinery insists on `historypb.History` framing, items get wrapped in a synthetic event. This needs verifying before implementation starts, and it is cheap to verify. + +**Walker.** OSS `NewHistoryBranch` ignores namespace, workflow, and run, but the interface accepts them because the SaaS storage layer uses them. Minting branches that are not tied to a run needs a check against `saas-temporal/walker/` before this goes past prototype. + +**Notifier scaling.** `service/history/chasm_notifier.go` uses a single global mutex and carries TODOs to that effect. Fine for a prototype, real work for fan-out at scale. + +**Cassandra.** Deliberately out of scope for the prototype, and it is the open question gating the batching decision for production. SQLite and Postgres numbers must not be read as answering it. + +## 9. Open questions + +- Offset as an integer or an opaque token. Integers are better ergonomics; tokens leave room to change the addressing later. +- Whether per-item metadata (workflow, run, original run, attempt) is populated by the server, and whether it is on by default. The rewind model depends on it existing; whether we fill it in is separable. +- Pricing. Data transferred, storage, and active minutes are the candidates. This design deliberately makes cost track bytes rather than item count, which is the shape the 1-pager asks for. +- Naming. "Stream" collides with Kafka Streams. Using `stream` for now. +- Whether the collection primitive that Metablock needs should be built on this, or the other way round. This design does not need it, which is a scheduling argument, not an architectural one. From 37a5a226647d7c0d67d76a1d40175ea1cc601370 Mon Sep 17 00:00:00 2001 From: Moe Dashti Date: Sun, 23 Aug 2026 02:08:30 -0700 Subject: [PATCH 02/79] Compared Native Streams against the two existing prototypes. Max's external-store prototype and Johann's dedicated-facet prototype both reach further than our design did in places, so the comparison is recorded and the twelve resulting changes are folded into both docs. The load-bearing one is a correctness fix: an in-workflow consumer must record its delivered range on every task, including empty ones, or replay can hand it items it did not have. Riding WorkflowTaskCompleted instead of a new event makes the idle case free. --- design-comparison.md | 193 ++++++++++++++++++++++++++++++++ streaming-detailed-design.md | 194 ++++++++++++++++++++++++++------- streaming-high-level-design.md | 83 ++++++++++---- 3 files changed, 407 insertions(+), 63 deletions(-) create mode 100644 design-comparison.md diff --git a/design-comparison.md b/design-comparison.md new file mode 100644 index 00000000000..f6507532697 --- /dev/null +++ b/design-comparison.md @@ -0,0 +1,193 @@ +# Native Streams: Design Comparison + +| | | +|---|---| +| Status | Draft for review | +| Ticket | [AI-198](https://temporalio.atlassian.net/browse/AI-198) | +| Author | Moe Dashti | +| Date | 2026-08-23 | +| Compares | `streaming-high-level-design.md` + `streaming-detailed-design.md` against two existing prototypes | + +Our design was written clean-room, before reading either prototype.

Where all three agree + +Worth stating, because the convergence is evidence the shape is right: + +- Items must not go into workflow history one per event. +- Offsets are the addressing model, and the reader carries its own cursor. +- Publishing must not wake the owning workflow. +- The stream outlives the workflow task that produced it, and close is distinct from delete. +- Rewinds on retry or reset are surfaced to the application rather than hidden. +- Topics, not predicates, for filtering. + +Most significantly, **Max and we independently arrived at the same replay model**: record the consumed offset range in history and re-read the bytes from an immutable log. He calls it a marker annotation, we call it a cursor event. That two designs built without knowledge of each other landed on the same mechanism is the strongest single signal in this comparison. + +--- + +## 4. Max's approach + +### What it gets right + +- **No server changes.** It could ship on today's server, which no other option can claim. +- **The replay model is correct and battle-tested.** Around 40 ADRs, each pairing a rule with the failure that occurs without it, and a conformance suite for backends. +- **It found the hard cases.** Cursor as a position boundary rather than a record identity (ADR-002), because a consumer parked at the tail has no next-record ID to persist. Progress as an observation delta emitted on every completion path (ADR-005), because a subscription that observed nothing still has to record that it observed nothing. Activation segmentation reproduced rather than collapsed (ADR-018), because `wait_condition` fires once per activation and collapsing k drains into one changes when conditions fire. +- **Cost claim is sharp**: history event cost scales with consumption batches and idle-to-active transitions, not item count, and marker bytes are capped by a byte budget that forces rollover instead of growing a marker. + +### Where it does not fit our goal + +- **Durability moves outside Temporal.** This is the objection the 7/23 options doc already recorded: if workflows replicate and the external stream does not, the guarantees become inconsistent. Structural immutability of the backend has to be asserted at registration time (ADR-003) rather than being true by construction, and the doc states plainly that a provider which silently violates it delivers altered bytes on replay with no error raised. +- **It needs an external system.** That is the Redis workaround the feature exists to remove, made official. The PRD lists extra infrastructure, split observability, and a second failure domain as the reasons the workaround is not sufficient. +- **Exactly-once producer execution is an explicit non-goal**, delegated to backend adapter idempotency. +- **The replay machinery is inherently complex** because the SDK reads the backend continuously while a workflow task is open. The boundary of what was observed is not a natural artifact of anything, so it has to be reconstructed: runs, segments, per-segment end reasons, sparse control positions, and a byte budget. +- Requires sdk-core changes, so "client side" means "no server changes", not "no protocol changes". + +### What we take + +1. **Record the range even when it is empty**, and carry the resolved start offset on first observation (ADR-005). Our Path C as written only wrote an event when items were delivered, which leaves replay unable to reproduce a task where the subscription observed nothing. That is a correctness hole, and this is the fix. +2. **A per-producer write fence distinct from closing the stream** (ADR-040). A producer can declare it is done without ending the stream for other producers. +3. **Bound delivery by record count as well as bytes** (ADR-026 with ADR-007). +4. **Attached-stream identity keyed on the first execution run ID**, so it is stable across a continue-as-new chain and does not collide after workflow ID reuse. +5. **Missing data on replay blocks rather than fails** (ADR-014): surface a retryable workflow task failure, not a nondeterminism error. + +### What we do not take + +The external backend itself. It is a legitimate product option for customers who want to pay a different price for volume, and the 1-pager says so. It is not this design. Our read API is offset plus long-poll, which is the same shape a backend adapter would expose, so the two can sit behind one client API later if we choose. + +--- + +## 5. Johann's approach + +### What it gets right + +- **The durability story is ours too**, and it is the right one: every item a subscriber sees is already persisted by the history server. +- **It is the most rigorous artifact of the three on the write path.** A TLA+ spec that TLC exhausts in about 15 seconds, with every action mapped to a Go function in `spec/SPEC_TO_CODE.md`. +- **It settled a lot of product surface** we would otherwise re-litigate: multi-topic streams with subscribe-time filtering, `ListStreams` for operators, owner link on business ID so it survives continue-as-new, close-not-delete on owner completion, no invented per-stream TTL, and end-to-end codec so the server never sees plaintext. +- **Positioning is explicit and honest**: many modest-volume streams, not a firehose, with per-stream throughput bounded by the CHASM transition rate on a single execution. +- **Inline retention truncation** at the end of each successful publish transition, with a consumer pin, rather than a separate sweeper. + +### Where we differ, and why + +**The persistence choice is the crux.** Johann's `persistence-abi.html` evaluates four approaches and picks C, a dedicated append-log facet. Its own stated rationale is that this "mirrors workflow history events, which the team already operates at scale". Our design takes that observation one step further: rather than building a facet that mirrors `history_node`, use `history_node`. + +The doc anticipates this and rejects it in one line: history's pattern is "inspiration but not a drop-in template" because "history's 12-hour scavenger and 60-day min-age work because history orphans are rare; streams generate them routinely (publish retries, truncate races, backpressure) and need a prepare / write / commit protocol with explicit visibility frontier and a 1-5 minute sweeper." + +That objection is about garbage, not correctness, and it has an answer that was not considered: + +- **Correctness is already handled by the store.** `filterHistoryNodes` (`common/persistence/history_manager.go:1039-1073`) does not merely prefer the higher transaction ID for the same node ID. It requires transaction IDs to be non-decreasing along the node chain and drops any node whose transaction ID went backwards. Its own comment says it: "event batches with larger node ID -> batch with lower transaction ID is invalid (happens before)". So an orphan beyond a retry's extent is dropped on read, not just an orphan at the same offset. Combined with clipping reads to `HeadOffset`, no reader can observe an orphan. +- **Garbage collection already has a purpose-built tool.** `TrimHistoryBranch(BranchToken, NodeID, TransactionID)` takes a known-valid frontier and removes everything off the valid chain. The Stream component holds exactly that frontier. So the sweep is a cheap pure task fired after a failed append, not a 12-hour scavenger. The premise that we would inherit history's coarse cleanup cadence does not hold. + +With those two, the prepare/write/commit protocol is not needed, and the design collapses to append-then-advance, which is the pair Temporal has run in production for a decade. + +The consequences are concrete: + +| | Johann's C | Ours | +|---|---|---| +| New tables | `stream_segments` + `stream_sealed_indexes`, 4 backends | none | +| Schema migrations | Cassandra 1.14, MySQL/PG 1.20, SQLite 0.12 | none | +| Commit protocol | 3 steps, TLA+ needed to trust it | append-then-advance | +| Cassandra LWTs per publish | 2 | 1 | +| Offset lookup structure | `SegmentIndex` on the chasm node, binary search, plus a close-time offload to a sibling table when it grows | none; the branch token plus a node-ID range read | +| Tentative-row sweeper | 1 to 5 minutes, required | pure task on failure, opportunistic | +| Replication | new facet needs its own story | rides history-node replication | + +Halving the LWT count matters more than it looks. Johann's own `spec/perf-back-of-envelope.md` identifies the per-partition LWT rate (budgeted at 100/sec) as the per-stream ceiling, and concludes that group commit is "load-bearing, not optional" to hit the 300 items/sec target. Starting at one LWT per publish rather than two doubles the base before group commit is applied, and group commit applies to our design equally. + +**The second difference is in-workflow consumption.** Johann's decision D9 pushes matching items to the workflow **as signals or updates on the consumer's own history**, at-least-once, with handlers deduplicating on item offset. That keeps items out of the *publisher's* history but puts them into the *consumer's*, which is the same cost in a different place, and it puts the dedup burden on user code. The Bellevue session later set the opposite requirement: "the end user never handles delivery deduplication". D9 predates that session, so this is a case of the session superseding an earlier decision rather than a disagreement. + +Our Path C records only the offset range and attaches the bytes to the workflow task response out of band, so nothing per-item enters the consumer's history and delivery is exactly-once by construction. It also needs no subscription state machine, no three-phase delivery protocol, and no outstanding-bytes arm step, because delivery is pulled at task-build time rather than pushed. + +There is a further advantage that only becomes visible next to Max's design. Because our delivery boundary is the workflow task boundary, and that boundary is already in history, we do not have the segmentation problem ADR-018 solves. One slice arrives per task, the SDK drains it once, and replay drains the identical slice once. No runs, no segments, no per-segment end reasons. + +### What we take + +1. **Group commit.** Coalesce concurrent appends to one stream into a single CHASM transition. This is the difference between meeting and missing the throughput target on Cassandra. +2. **Explicit positioning and a stated per-stream ceiling**, rather than letting readers assume a firehose. +3. **Inline retention truncation** at the end of a publish transition, with a consumer pin, instead of a sweeper. +4. **Multi-topic streams with subscribe-time filtering**, and `ListStreams` for operators. +5. **Owner link on business ID, close-not-delete on owner completion**, and no invented per-stream TTL beyond the lifecycle policy the Bellevue session asked for. +6. **Say out loud that the server never sees plaintext.** Our blobs are opaque already, so the codec property is free; it just was not written down. + +--- + +## 6. What our design has that neither does + +Stated plainly so it can be attacked: + +1. **No new storage.** Reusing `history_node` removes two tables, four schema migrations, an index structure with its own offload path, and a sweeper. +2. **No commit protocol.** The clip invariant plus the transaction-ID chain gives exactly-once without a prepare phase, which is why no TLA+ spec is required to trust it. +3. **No dependency on CHASM partial reads.** `OSS-4917` and `OSS-4918` are both still `To Do`. Johann's revised plan (analysis §5.1) puts streams on a shared CHASM collection primitive owned by another team, which is the current critical path. Payload bytes never enter the CHASM tree in our design, so that dependency disappears. This is a scheduling argument, not an architectural one, but D1 is due at the September 14 check-in. +4. **In-workflow consumption at no per-item history cost**, and exactly-once without user-side dedup. +5. **Replication is inherited** rather than designed, because history-node data already replicates. + +And the honest counterweight: **ours is a design, theirs are working code.** Johann's has a verified spec and a passing end-to-end test.

The stale node at 110 is now *below* the frontier, so clipping alone would expose it.

The Native Streams design reuses the history-node store for stream payloads instead of standing up a parallel one, which rests on two properties that were only ever read off the code. Both now have tests on SQLite and Postgres: a non-proto blob round-trips byte-identical on a branch whose tree ID is not a run ID, and the transaction-ID chain rejects a stale node left by a shrinking retry once the frontier has moved past it. The stale-node case is asserted on the raw read path as well, since that is the path a stream uses and it carries no contiguity check of its own. A negative control confirms the assertion is load-bearing. --- .../tests/history_store_stream_log.go | 179 ++++++++++++++++++ design-comparison.md | 3 +- streaming-detailed-design.md | 4 +- streaming-high-level-design.md | 7 +- 4 files changed, 190 insertions(+), 3 deletions(-) create mode 100644 common/persistence/tests/history_store_stream_log.go diff --git a/common/persistence/tests/history_store_stream_log.go b/common/persistence/tests/history_store_stream_log.go new file mode 100644 index 00000000000..92f114e7a2c --- /dev/null +++ b/common/persistence/tests/history_store_stream_log.go @@ -0,0 +1,179 @@ +package tests + +import ( + "time" + + "github.com/google/uuid" + commonpb "go.temporal.io/api/common/v1" + enumspb "go.temporal.io/api/enums/v1" + historypb "go.temporal.io/api/history/v1" + persistencespb "go.temporal.io/server/api/persistence/v1" + "go.temporal.io/server/common" + p "go.temporal.io/server/common/persistence" +) + +// Tests covering the history-node store's behaviour as a general append-only +// log, addressed by a branch whose tree ID is not a workflow run ID. +// +// These exist because a stream primitive reuses this store directly rather than +// standing up a parallel one.

Max's own prototype found more: ADR-018 concludes that replay must reproduce **activation segmentation**, the number of drains, not just the record order, because `wait_condition` predicates evaluate once per activation and collapsing k drains into one changes when conditions fire. ADR-005 adds that the first observation of a subscription must carry provider identity and resolved start boundary even when nothing was delivered. Those are real and already solved in the branch, but they are not in the summary, so the summary understates the replay work. +4. **Durability of the wake-up.** The notes say the signal must be durable, then float a rejected update as a lighter-weight substitute.

Dependencies and risks From 60fc8940292b3a5fe30bcb1715079c66f67ee699 Mon Sep 17 00:00:00 2001 From: Moe Dashti Date: Sun, 23 Aug 2026 15:07:31 -0700 Subject: [PATCH 06/79] Took the partition fix and run-transition handling from the Codex design. Codex independently reached nearly the same architecture, and found a real flaw in ours. history_node partitions on tree_id alone, which is safe for workflow history because history is capped and unsafe for a stream because it is not. Streams now roll to a new tree every bucket_size offsets; the bucket is arithmetic so there is still no index. Also filled three gaps it exposed: continue-as-new for an attached stream needs the successor to inherit the state and the old child to redirect, reset must carry the current head forward rather than rewind, and a missing committed node has to read as DataLoss rather than as an empty stream. Group commit moves to deferred, matching their reasoning that the case for it rests on Cassandra numbers this prototype does not measure. --- design-comparison.md | 58 ++++++++++++++++++-- streaming-detailed-design.md | 98 +++++++++++++++++++++++++++++++--- streaming-high-level-design.md | 8 ++- 3 files changed, 152 insertions(+), 12 deletions(-) diff --git a/design-comparison.md b/design-comparison.md index 69b50dbd10f..87cfa3277b8 100644 --- a/design-comparison.md +++ b/design-comparison.md @@ -188,7 +188,49 @@ There is a further advantage that only becomes visible next to Max's design.

It is a design document, not running code, and it is by far the closest to ours: bounded CHASM control plane, append-only collection data plane, no stream events in Workflow History, stateless consumers with client-held cursors, long-poll on the CHASM notifier, durable-before-visible, and the same append-then-CAS visibility rule with transaction-chain selection. It reaches those independently, which is worth something on its own. + +Three differences of substance: + +- **It is workflow-attached only.** Standalone streams are an explicit non-goal, on the grounds that a standalone stream turns a Workflow publisher into a cross-execution write needing an outbox. We support both, and reach the same conclusion by a different route: a Workflow publishing to a stream it does not own uses the RPC, not a command, so no cross-execution transaction arises. +- **It does bucket 1 only.** Pushing into a consuming Workflow is a non-goal, so there is no Path C equivalent. +- **It uses a dedicated persistence facet**, like Johann's, rather than reusing `history_node`. + +### The flaw it found in ours + +Its §7.3 requires a bounded physical partition, with `partition_id = offset / partition_message_count`. Checking that against our design: `history_node` in Cassandra is `PRIMARY KEY ((tree_id), branch_id, node_id, txn_id)`, so **the partition key is `tree_id` alone**. Every node of a tree lives in one partition. + +That is safe for Workflow History because history is capped by `HistorySizeLimitError` and `HistoryCountLimitError`. It is not safe for a stream, which the 1-pager explicitly wants unbounded. Reusing `history_node` as-is inherits a partition layout whose safety depends on a cap we are deliberately removing. Large Cassandra partitions degrade compaction and read latency well before anything fails outright. + +We had not noticed this. It is the most useful thing in the document. + +The fix keeps the `history_node` reuse and stays O(1): roll to a new tree every `bucketSize` offsets, with `bucket = offset / bucketSize` and the tree ID derived deterministically from `(streamID, bucket)` via `uuid.NewSHA1`. No index, because the mapping is arithmetic. Reads spanning a boundary issue one range read per bucket, and whole-bucket truncation becomes `DeleteHistoryBranch` rather than per-row tombstones, which is the same benefit Codex gets from buckets. + +Bucketing does not weaken the transaction-chain protection, though the argument is not obvious and needs a test. Bucket boundaries are offset-aligned, so any stale node is either the bucket's first node, where it shares a node ID with the real first node and loses on transaction ID, or it is preceded within its bucket by valid nodes, where the chain rule applies as it does within a single tree. + +### The other gaps it exposed + +- **Continue-as-new for an attached stream.** Ours says continue-as-new needs no handling. That is true for a standalone stream and false for an attached one, where the component lives in a run that is about to be superseded. Codex copies the bounded state into the successor and marks the old child `REDIRECTED` with the new run ID, so an in-flight long poll follows the chain without losing its cursor. We had no answer. +- **Reset.** Ours says the workflow rewinds and the stream does not, which is the right conclusion with none of the mechanism. Codex carries the latest stream state forward into the reset snapshot rather than the state at the reset point, and works through the append-versus-reset race on the current-execution condition. Ours had nothing on the race. +- **Missing data reads as data loss, not as an empty stream** (invariant 3.2.6). Ours would return an empty range if branch data vanished, which is the worst possible failure for a durable stream. We get this more cheaply than Codex does, because our control state already holds the frontier: if a read returns fewer nodes than `HeadOffset` implies, that is `DataLoss`. Codex needs a separate manifest for it because their equivalent state can be rebuilt from history. +- **Different content under a retried sequence must be rejected** (invariant 3.4.3). Ours returns the recorded offsets on a sequence match without comparing content, so a client bug silently drops data. +- **The event-sourcing boundary needs explicit sign-off.** Both designs make stream control non-replayable auxiliary CHASM state. Codex names that as an architecture exception requiring History and CHASM owner approval plus a `docs/architecture` update. Ours does the same thing without flagging it as a governance item. + +### Where we disagree + +Codex defers group commit until measurement proves it necessary; we took it from Johann. Johann's own back-of-envelope says it is load-bearing on Cassandra, and Cassandra is out of prototype scope, so deferring the implementation while keeping the design is the honest position. Moving ours to deferred. + +On the facet, Codex's §7.1 gives five reasons for a dedicated store. Bucketing answers two of them (bounded partitions, truncation on buckets rather than branches). One does not apply to us, since our tree is not tied to a run. We verified the raw paths do not assume History Events. The remaining reason, different replication and garbage-collection ownership metadata, is real and deferred. So the facet case is weaker after bucketing, but not zero, and it is the strongest remaining argument against our storage choice. + +### What we do not take + +The manifest `PREPARED` / `ATTACHED` / `CLOSED` state machine and the quarantined-child sentinel. The invariant behind them is right and we are adopting it; the machinery exists to solve a problem we do not have, because our head authority is not reconstructible from history.

Stage 0 of AI-198. Reproduces the shipped pattern, batched Signals in and a long-polling Update out, and measures history events, history bytes, persistence operations, and latency across flush interval and subscriber count. Nothing to compare a native path against without it. Latency is stamped at generation rather than at flush. Stamping at flush measures only the server round trip and hides the batching delay, which is the dominant term and the whole reason a shorter interval is wanted. Two ceilings fell out that matter more than the cost curve. history.maxInFlightUpdates caps concurrent subscribers at 10 and starves rather than degrades past it. history.maxTotalUpdates gives a workflow 2000 reads for its entire life, so at 100ms batching five subscribers exhaust it in under a minute and force continue-as-new for reasons that have nothing to do with the application. --- streaming-baseline-results.md | 74 ++++++ streaming-high-level-design.md | 7 +- tests/streaming_baseline_test.go | 438 +++++++++++++++++++++++++++++++ 3 files changed, 516 insertions(+), 3 deletions(-) create mode 100644 streaming-baseline-results.md create mode 100644 tests/streaming_baseline_test.go diff --git a/streaming-baseline-results.md b/streaming-baseline-results.md new file mode 100644 index 00000000000..2c03b618b8d --- /dev/null +++ b/streaming-baseline-results.md @@ -0,0 +1,74 @@ +# Workflow Streams: measured baseline + +| | | +|---|---| +| Status | First measurement, single run per cell | +| Ticket | [AI-198](https://temporalio.atlassian.net/browse/AI-198), Stage 0 | +| Harness | `tests/streaming_baseline_test.go` | +| Date | 2026-08-24 | + +What today's Workflow Streams pattern costs, measured rather than argued.

Stage 1 of AI-198. The component holds only the frontier: head and base offsets, the transaction chain, producer dedup, and consumer pins. It is O(producers + consumers) rather than O(messages), which is what keeps it off the CHASM partial-read path. Payload bytes go to the history-node store on trees of the stream's own, rolling to a new tree every bucket_size offsets. That is not cosmetic: the Cassandra table partitions on tree_id alone, which is safe for workflow history because history is capped and unsafe for a stream because it is not. Buckets are arithmetic and tree IDs derive from them, so nothing indexes them. The component stages appends rather than writing them. Keeping the staging separate from the transaction is what will let an append ride a workflow's own commit later without the component knowing. Transaction IDs come from the caller rather than from stream state: a retry has to carry a higher ID than the attempt it replaces, and a counter derived from committed state would hand the retry the same one. The bucket-boundary test earned its place twice. It found a real bug where the result cap was passed through as a storage page size, which made the store read past the end of an empty result. Its negative control confirms the transaction chain, not luck, is what rejects a stale node in a freshly started tree. --- .../gen/streampb/v1/message.go-helpers.pb.go | 101 ++++ .../lib/stream/gen/streampb/v1/message.pb.go | 293 +++++++++++ .../streampb/v1/stream_state.go-helpers.pb.go | 154 ++++++ .../stream/gen/streampb/v1/stream_state.pb.go | 487 ++++++++++++++++++ chasm/lib/stream/library.go | 38 ++ chasm/lib/stream/log.go | 182 +++++++ chasm/lib/stream/proto/v1/message.proto | 34 ++ chasm/lib/stream/proto/v1/stream_state.proto | 69 +++ chasm/lib/stream/stream.go | 295 +++++++++++ chasm/lib/stream/stream_test.go | 227 ++++++++ .../tests/history_store_stream_log.go | 92 ++++ 11 files changed, 1972 insertions(+) create mode 100644 chasm/lib/stream/gen/streampb/v1/message.go-helpers.pb.go create mode 100644 chasm/lib/stream/gen/streampb/v1/message.pb.go create mode 100644 chasm/lib/stream/gen/streampb/v1/stream_state.go-helpers.pb.go create mode 100644 chasm/lib/stream/gen/streampb/v1/stream_state.pb.go create mode 100644 chasm/lib/stream/library.go create mode 100644 chasm/lib/stream/log.go create mode 100644 chasm/lib/stream/proto/v1/message.proto create mode 100644 chasm/lib/stream/proto/v1/stream_state.proto create mode 100644 chasm/lib/stream/stream.go create mode 100644 chasm/lib/stream/stream_test.go diff --git a/chasm/lib/stream/gen/streampb/v1/message.go-helpers.pb.go b/chasm/lib/stream/gen/streampb/v1/message.go-helpers.pb.go new file mode 100644 index 00000000000..28778a8fce9 --- /dev/null +++ b/chasm/lib/stream/gen/streampb/v1/message.go-helpers.pb.go @@ -0,0 +1,101 @@ +// Code generated by protoc-gen-go-helpers.

Eight shard-routed RPCs, with the request shapes declared in the library rather than in the public API, since streams have no public API yet. Nesting them under frontend_request matches the other CHASM libraries, so promoting them later is a package move rather than a redesign. PollMessages is categorised as a long poll so it lands in the right quota bucket, though it does not block yet. ListStreams is left out: it needs a visibility field and search attributes on the component, which belongs with the lifecycle work rather than here, and nothing on the benchmark path reads it. --- .../v1/request_response.go-helpers.pb.go | 1190 ++++++++++ .../gen/streampb/v1/request_response.pb.go | 1911 +++++++++++++++++ .../lib/stream/gen/streampb/v1/service.pb.go | 105 + .../gen/streampb/v1/service_client.pb.go | 411 ++++ .../stream/gen/streampb/v1/service_grpc.pb.go | 369 ++++ .../stream/proto/v1/request_response.proto | 171 ++ chasm/lib/stream/proto/v1/service.proto | 51 + 7 files changed, 4208 insertions(+) create mode 100644 chasm/lib/stream/gen/streampb/v1/request_response.go-helpers.pb.go create mode 100644 chasm/lib/stream/gen/streampb/v1/request_response.pb.go create mode 100644 chasm/lib/stream/gen/streampb/v1/service.pb.go create mode 100644 chasm/lib/stream/gen/streampb/v1/service_client.pb.go create mode 100644 chasm/lib/stream/gen/streampb/v1/service_grpc.pb.go create mode 100644 chasm/lib/stream/proto/v1/request_response.proto create mode 100644 chasm/lib/stream/proto/v1/service.proto diff --git a/chasm/lib/stream/gen/streampb/v1/request_response.go-helpers.pb.go b/chasm/lib/stream/gen/streampb/v1/request_response.go-helpers.pb.go new file mode 100644 index 00000000000..b442cfd4159 --- /dev/null +++ b/chasm/lib/stream/gen/streampb/v1/request_response.go-helpers.pb.go @@ -0,0 +1,1190 @@ +// Code generated by protoc-gen-go-helpers.

History registers the library and serves the service; frontend resolves the namespace name and forwards over the layered client, which routes to the shard owning the stream. The frontend registers the service on its gRPC server directly rather than embedding a handler in WorkflowHandler, because StreamService is not part of the public API. Appends are serialized per stream in the handler. The node has to be durable before the frontier advances, so it is written outside the transition that advances it, and two concurrent writers could otherwise commit in a different order than they wrote: whichever node carried the higher transaction ID would win the read regardless of which writer actually committed. Serializing removes the interleaving. It is a stopgap for the CHASM transaction hook, and it is noted as such in the handler rather than left for someone to discover. --- chasm/lib/stream/config.go | 4 + chasm/lib/stream/frontend.go | 140 +++++++++++++ chasm/lib/stream/fx.go | 28 +++ chasm/lib/stream/handler.go | 369 +++++++++++++++++++++++++++++++++++ chasm/lib/stream/library.go | 37 +++- chasm/lib/stream/stream.go | 24 +++ service/frontend/fx.go | 4 + service/frontend/service.go | 6 + service/history/fx.go | 2 + 9 files changed, 611 insertions(+), 3 deletions(-) create mode 100644 chasm/lib/stream/config.go create mode 100644 chasm/lib/stream/frontend.go create mode 100644 chasm/lib/stream/fx.go create mode 100644 chasm/lib/stream/handler.go diff --git a/chasm/lib/stream/config.go b/chasm/lib/stream/config.go new file mode 100644 index 00000000000..e138060e120 --- /dev/null +++ b/chasm/lib/stream/config.go @@ -0,0 +1,4 @@ +package stream + +// defaultMaxMessagesPerPoll bounds a read page when the caller does not. +const defaultMaxMessagesPerPoll = 1000 diff --git a/chasm/lib/stream/frontend.go b/chasm/lib/stream/frontend.go new file mode 100644 index 00000000000..ff3290849e3 --- /dev/null +++ b/chasm/lib/stream/frontend.go @@ -0,0 +1,140 @@ +package stream + +import ( + "context" + + "go.temporal.io/api/serviceerror" + streampb "go.temporal.io/server/chasm/lib/stream/gen/streampb/v1" + "go.temporal.io/server/common/log" + "go.temporal.io/server/common/namespace" +) + +// FrontendHandler serves StreamService on the frontend.

Reads starting inside a batch silently dropped everything before the batch boundary. A node is addressed by the first offset of its batch, so a read has to begin at the node containing the offset, not at the node whose ID equals it. Batch size is now bounded on write, which bounds how far back a read steps; the bound is a correctness mechanism, not only admission control. A negative control confirms the test catches it. Producer and consumer maps come back nil after deserialization, so appends against a reloaded stream failed on a nil map write. Guarded at each write rather than relying on the constructor. Truncation, close, dedup, topic filtering, and per-producer fencing are covered end to end through the frontend. --- chasm/lib/stream/config.go | 7 + chasm/lib/stream/log.go | 12 +- chasm/lib/stream/stream.go | 10 ++ tests/stream_test.go | 309 +++++++++++++++++++++++++++++++++++++ 4 files changed, 337 insertions(+), 1 deletion(-) create mode 100644 tests/stream_test.go diff --git a/chasm/lib/stream/config.go b/chasm/lib/stream/config.go index e138060e120..8ed5aff44cb 100644 --- a/chasm/lib/stream/config.go +++ b/chasm/lib/stream/config.go @@ -2,3 +2,10 @@ package stream // defaultMaxMessagesPerPoll bounds a read page when the caller does not. const defaultMaxMessagesPerPoll = 1000 + +// MaxMessagesPerBatch bounds one append.

A caught-up reader now parks on chasm.PollComponent until the head moves past it or the stream closes. The predicate is monotonic as that API requires: the head only advances and closed never clears. Expiry of the server's own budget returns an empty response rather than an error, so a reader cannot confuse a quiet stream with a failure. A reader that is already behind is never parked. The tail cache keeps recently appended batches in memory so a reader at the tail is served without a database read. That is what makes fan-out cheap: readers at the tail cost a copy each rather than a range scan each, which is the difference between a subscriber ceiling and none. Two properties it has to hold. It caches only after the commit, because a write whose commit failed can be superseded by a retry carrying different bytes at the same offsets. And a partial hit is a miss: returning only the tail of a requested range would look like a short read, which is the shape of a silent data loss. Group commit stays deferred. The case for it rests on Cassandra numbers this prototype does not measure. --- chasm/lib/stream/config.go | 18 +++ .../gen/streampb/v1/request_response.pb.go | 22 ++- chasm/lib/stream/handler.go | 91 ++++++++++-- .../stream/proto/v1/request_response.proto | 5 + chasm/lib/stream/tailcache.go | 138 ++++++++++++++++++ chasm/lib/stream/tailcache_test.go | 86 +++++++++++ tests/stream_test.go | 109 ++++++++++++++ 7 files changed, 455 insertions(+), 14 deletions(-) create mode 100644 chasm/lib/stream/tailcache.go create mode 100644 chasm/lib/stream/tailcache_test.go diff --git a/chasm/lib/stream/config.go b/chasm/lib/stream/config.go index 8ed5aff44cb..7018e76e7fc 100644 --- a/chasm/lib/stream/config.go +++ b/chasm/lib/stream/config.go @@ -1,5 +1,7 @@ package stream +import "time" + // defaultMaxMessagesPerPoll bounds a read page when the caller does not. const defaultMaxMessagesPerPoll = 1000 @@ -9,3 +11,19 @@ const defaultMaxMessagesPerPoll = 1000 // bounds how far back it has to start, which turns an unbounded scan into a // fixed overread. const MaxMessagesPerBatch = 1000 + +// longPollTimeout matches the convention used by the history long polls: on +// expiry the caller gets an empty response and polls again, rather than an +// error it would have to special-case. +const longPollTimeout = 20 * time.Second + +// longPollBuffer leaves room to return an empty response before the caller's +// own deadline fires. +const longPollBuffer = 3 * time.Second + +// Tail-cache bounds.

A capped stream now advances its own readable floor at the end of a successful append rather than through a sweeper. The append transition is already writing, so folding the check into it costs nothing and keeps the cap tight instead of eventually true. Truncation reclaims whole buckets. That is the point of bucketing: a storage partition is dropped outright rather than leaving a tombstone per message. Deletion always follows the commit that moved the floor, so a failure leaks storage to reclaim later rather than losing data a reader can still ask for. The cap yields to a registered workflow consumer. That consumer's history records an offset range it must re-read on replay, so storage grows rather than the consumer losing data underneath it. Close now records when and arms a retention task; deletion removes the log before the execution, since the other order would drop the only record of which buckets exist and leak them permanently. Close became a pure function returning when to schedule, with the caller arming the task. That keeps the component testable without a live context, matching how appends already stage rather than persist. max_bytes is removed from the lifecycle proto rather than left accepted and silently ignored.

Streams now carry a visibility field and ListStreams answers from visibility on the frontend. Without it the only way to reach a stream is to already know its ID, which is not something an operator can work with. It is deliberately not on the history handler: the query is against visibility rather than any one stream, so there is no business ID to route on and nothing a shard could answer. Unit tests build the component directly instead of through NewStream, which now needs a live context to wire the visibility field. Construction through the real path stays covered end to end. --- chasm/lib/stream/config.go | 3 + chasm/lib/stream/frontend.go | 42 +++ .../v1/request_response.go-helpers.pb.go | 185 ++++++++++ .../gen/streampb/v1/request_response.pb.go | 348 ++++++++++++++++-- .../lib/stream/gen/streampb/v1/service.pb.go | 49 +-- .../gen/streampb/v1/service_client.pb.go | 44 +++ .../stream/gen/streampb/v1/service_grpc.pb.go | 41 +++ chasm/lib/stream/handler.go | 3 + .../stream/proto/v1/request_response.proto | 25 ++ chasm/lib/stream/proto/v1/service.proto | 7 + chasm/lib/stream/stream.go | 8 +- chasm/lib/stream/stream_test.go | 18 +- tests/stream_test.go | 32 ++ 13 files changed, 748 insertions(+), 57 deletions(-) diff --git a/chasm/lib/stream/config.go b/chasm/lib/stream/config.go index 7018e76e7fc..657a2a3eb06 100644 --- a/chasm/lib/stream/config.go +++ b/chasm/lib/stream/config.go @@ -27,3 +27,6 @@ const ( tailCacheBytesPerStream = 1 << 20 tailCacheMaxStreams = 4096 ) + +// maxListPageSize bounds a visibility page when the caller does not. +const maxListPageSize = 1000 diff --git a/chasm/lib/stream/frontend.go b/chasm/lib/stream/frontend.go index ff3290849e3..340b1392d56 100644 --- a/chasm/lib/stream/frontend.go +++ b/chasm/lib/stream/frontend.go @@ -4,9 +4,11 @@ import ( "context" "go.temporal.io/api/serviceerror" + "go.temporal.io/server/chasm" streampb "go.temporal.io/server/chasm/lib/stream/gen/streampb/v1" "go.temporal.io/server/common/log" "go.temporal.io/server/common/namespace" + "google.golang.org/protobuf/types/known/emptypb" ) // FrontendHandler serves StreamService on the frontend.

Persistence metrics and rate limits are keyed on caller info carried by the context, not on the request. The RPC path sets it through interceptors, but the stream writes its log directly, so those calls carried no caller name at all. They were escaping namespace rate limiting and priority, and going uncounted in per-namespace metrics. Found while building the native half of the benchmark, which reported zero persistence operations per message for a path that demonstrably writes on every append. Worth stating plainly: the first version of that number was a fiction, and only the raw per-operation breakdown exposed it. The retention task needs the same treatment, since it runs outside any request. --- chasm/lib/stream/handler.go | 38 ++++- chasm/lib/stream/tasks.go | 24 ++- tests/streaming_native_test.go | 258 +++++++++++++++++++++++++++++++++ 3 files changed, 309 insertions(+), 11 deletions(-) create mode 100644 tests/streaming_native_test.go diff --git a/chasm/lib/stream/handler.go b/chasm/lib/stream/handler.go index b5828f550bd..533bead282d 100644 --- a/chasm/lib/stream/handler.go +++ b/chasm/lib/stream/handler.go @@ -10,6 +10,7 @@ import ( streampb "go.temporal.io/server/chasm/lib/stream/gen/streampb/v1" "go.temporal.io/server/common" "go.temporal.io/server/common/contextutil" + "go.temporal.io/server/common/headers" "go.temporal.io/server/common/log" "go.temporal.io/server/common/log/tag" "go.temporal.io/server/common/namespace" @@ -21,8 +22,9 @@ import ( type handler struct { streampb.UnimplementedStreamServiceServer - shardController shard.Controller - logger log.Logger + shardController shard.Controller + namespaceRegistry namespace.Registry + logger log.Logger // Appends to one stream are serialized here.

Without one, every append and every poll resolved the stream's current run through persistence. That lookup dominated: at 100ms batching the native path spent 302 of 423 persistence operations on it, which made an otherwise free read cost a database call and left the design no cheaper than the pattern it replaces. Supplying the run id, which CreateStream already returns, takes the same workload from 423 operations to 121 against the baseline's 408. The remaining native cost is exactly what the design predicts: one log append and one frontier update per flush, and nothing at all for reads. Optional, and defaulting to the current run, matching how run ids work elsewhere in the API. --- .../gen/streampb/v1/request_response.pb.go | 41 ++++++++++++++----- chasm/lib/stream/handler.go | 12 +++++- .../stream/proto/v1/request_response.proto | 5 +++ tests/streaming_native_test.go | 15 +++---- 4 files changed, 54 insertions(+), 19 deletions(-) diff --git a/chasm/lib/stream/gen/streampb/v1/request_response.pb.go b/chasm/lib/stream/gen/streampb/v1/request_response.pb.go index 0efb0d1450e..cbb0eceb33f 100644 --- a/chasm/lib/stream/gen/streampb/v1/request_response.pb.go +++ b/chasm/lib/stream/gen/streampb/v1/request_response.pb.go @@ -131,7 +131,10 @@ type AddMessagesInput struct { state protoimpl.MessageState `protogen:"open.v1"` Namespace string `protobuf:"bytes,1,opt,name=namespace,proto3" json:"namespace,omitempty"` StreamId string `protobuf:"bytes,2,opt,name=stream_id,json=streamId,proto3" json:"stream_id,omitempty"` - Messages []*StreamMessage `protobuf:"bytes,3,rep,name=messages,proto3" json:"messages,omitempty"` + // Optional.

The native path delivers 100% with a 104ms p99 at a twentieth of the persistence cost per message. The shape matters more than the ratio: native cost per message barely moves between 1 and 25 subscribers because reads cost no persistence operations at all, while the current pattern's rises sevenfold over the same range.

The Command attributes oneof is closed and the module cache is read only, so a workflow cannot publish to a stream without changing the public API module.

A clean clone cannot generate at all, plain buf generate leaves an enum prefix the published module strips, and the pipeline does not emit several packages the module ships. All of that is written down rather than left for the next person.

The published module is a reshaped artifact: generated Go is emitted under `temporal/api/...` and then flattened to the module root by the Makefile's `fix-path`. So a fork needs the generation toolchain sorted out before it produces anything importable. +Worth recording, because none of it is obvious and all of it cost time. -**A local `replace` would not be enough.** It would make this branch unbuildable for anyone without the same checkout at the same path, which defeats the point of a prototype meant to be reviewed. +**A clean clone cannot generate.** `buf.gen.yaml` runs a `go-helpers` plugin from `./protoc-gen-go-helpers`, a directory absent from the repository, and there is no `go.mod`. Both live in the published module, so the fork takes them from there. -The unblock is a branch pushed to `temporalio/api` and pinned by pseudo-version. That is a change to a shared repository and needs a decision from someone who owns it, not a unilateral push. +**Plain `buf generate` produces a module the server cannot compile against.** It leaves the `CommandType_` prefix on enum constants, while the published module has them bare. The stripping is done by `protogen`'s const rewriter (`cmd/protogen/const_rewriter.go`), so generation has to go through `protogen` rather than `buf` directly. + +**The pipeline does not emit everything the module ships.** Missing after a full generate: `operatorservicemock`, `proxy`, `serviceerror`, `temporalnexus`, `temporalproto`, `workflowservicemock`, the grpc-gateway `.pb.gw.go` files, and a few hand-written `.go` files sitting beside generated ones such as `common/v1/payload_json.go`. All are taken from the published module unchanged, since none are touched by the stream changes. + +**The generated output is reshaped.** Go is emitted under `temporal/api/...` and flattened to the module root by the Makefile's `fix-path`.

I had this wrong. temporalio/api is protos-only by design and temporalio/api-go is the Go module, carrying api as a submodule and regenerating with make update-proto. My earlier note claimed a clean clone of api "cannot generate", which is backwards: it is not meant to. So the previous fork was a hand-assembled module built by copying pieces out of the published artifact. It compiled, but it could not be regenerated and would have misled anyone who opened it. Replaced with the supported shape: a proto-only branch on moedash/api, and moedash/api-go regenerated from it through its own make targets with the submodule pointed at that branch. The proto diff is now 65 lines with no vendored Go alongside it. --- .../proposals/README-api-go-stream-changes.md | 55 +++++--- docs/proposals/api-go-stream-changes.patch | 133 ------------------ go.mod | 2 +- go.sum | 4 +- 4 files changed, 40 insertions(+), 154 deletions(-) delete mode 100644 docs/proposals/api-go-stream-changes.patch diff --git a/docs/proposals/README-api-go-stream-changes.md b/docs/proposals/README-api-go-stream-changes.md index ff4ec59fa01..0a6da14abf1 100644 --- a/docs/proposals/README-api-go-stream-changes.md +++ b/docs/proposals/README-api-go-stream-changes.md @@ -1,37 +1,56 @@ -# The `go.temporal.io/api` changes Paths A and C need +# The API changes Paths A and C need -Stages 5 and 6 of AI-198 cannot be built without changing the public API module.

The stream is a co-located subcomponent of the workflow, so its frontier advances in the workflow task's own commit. The test asserts what that buys: publishing writes no history event at all. A command handler runs under the state lock with no context for I/O, so it cannot write the log itself. It stages the write, the task handler collects it, and RespondWorkflowTaskCompleted flushes before the commit that makes the offsets visible. A crash between the two leaves nodes at or past the frontier, which no reader can observe, and the retried task stages them again. Reusing a transaction id across workflow task attempts is safe here in a way it is not for an external producer: replay is deterministic, so a reused id lands identical bytes at the same node, which the store treats as an idempotent overwrite. The hazard the external path guards against is differing content under an equal id, which replay cannot produce. Three things this turned up. The stream package had to split, because the service half imports the history service and the workflow library cannot import that; the component now lives in chasm/lib/stream and the service in chasm/lib/stream/service. The command attribute validator rejects unknown command types by design, to make new commands declare whether they close the workflow, so this one is listed as non-closing. And a visibility component must be an immediate child of a CHASM root, so an attached stream carries none. An attached stream is not yet readable through the stream API: it has no standalone id to route on, and reaching it needs a path-addressed component reference that CHASM does not expose. The test asserts that gap rather than tolerating it, so it will fail and say so when it closes. --- .claude/skills/blame/SKILL.md | 12 ++ .claude/skills/log/SKILL.md | 23 ++++ .claude/skills/show/SKILL.md | 12 ++ chasm/lib/stream/config.go | 20 +-- chasm/lib/stream/{ => service}/frontend.go | 9 +- chasm/lib/stream/{ => service}/fx.go | 2 +- chasm/lib/stream/{ => service}/handler.go | 67 +++++---- chasm/lib/stream/{ => service}/library.go | 5 +- chasm/lib/stream/{ => service}/tasks.go | 15 +- chasm/lib/stream/stream.go | 23 +++- chasm/lib/stream/tailcache.go | 18 +-- chasm/lib/stream/tailcache_test.go | 54 ++++---- chasm/lib/workflow/fx.go | 3 + chasm/lib/workflow/stream_commands.go | 128 ++++++++++++++++++ chasm/lib/workflow/workflow.go | 32 +++++ service/frontend/fx.go | 2 +- service/frontend/service.go | 2 +- service/history/api/command_attr_validator.go | 5 +- .../api/respondworkflowtaskcompleted/api.go | 15 ++ .../stream_appends.go | 32 +++++ .../workflow_task_completed_handler.go | 9 ++ service/history/fx.go | 2 +- tests/api_fork_test.go | 10 +- tests/stream_test.go | 33 +++-- tests/stream_workflow_test.go | 106 +++++++++++++++ 25 files changed, 525 insertions(+), 114 deletions(-) create mode 100644 .claude/skills/blame/SKILL.md create mode 100644 .claude/skills/log/SKILL.md create mode 100644 .claude/skills/show/SKILL.md rename chasm/lib/stream/{ => service}/frontend.go (95%) rename chasm/lib/stream/{ => service}/fx.go (97%) rename chasm/lib/stream/{ => service}/handler.go (85%) rename chasm/lib/stream/{ => service}/library.go (93%) rename chasm/lib/stream/{ => service}/tasks.go (83%) create mode 100644 chasm/lib/workflow/stream_commands.go create mode 100644 service/history/api/respondworkflowtaskcompleted/stream_appends.go create mode 100644 tests/stream_workflow_test.go diff --git a/.claude/skills/blame/SKILL.md b/.claude/skills/blame/SKILL.md new file mode 100644 index 00000000000..83cdcfd5010 --- /dev/null +++ b/.claude/skills/blame/SKILL.md @@ -0,0 +1,12 @@ +--- +description: Show which re_gent step last modified each line of a file.

The field has to exist on four messages, because both the history and the matching response keep a wire-compatible twin for the raw-history path, and then be copied by hand at each of the three hops.

The cursor sits under the consuming workflow rather than on the stream so that folding in a delivered range commits with the event recording it. On the stream it would be a cross-execution write, and a crash between the two would redeliver or skip. An empty range still counts as pending, because a task that observed nothing is a fact replay has to reproduce. --- chasm/lib/stream/cursor.go | 134 ++++++++++++++++ chasm/lib/stream/cursor_test.go | 118 ++++++++++++++ .../streampb/v1/stream_state.go-helpers.pb.go | 37 +++++ .../stream/gen/streampb/v1/stream_state.pb.go | 151 +++++++++++++++--- chasm/lib/stream/proto/v1/stream_state.proto | 23 +++ chasm/lib/workflow/workflow.go | 43 +++++ 6 files changed, 488 insertions(+), 18 deletions(-) create mode 100644 chasm/lib/stream/cursor.go create mode 100644 chasm/lib/stream/cursor_test.go diff --git a/chasm/lib/stream/cursor.go b/chasm/lib/stream/cursor.go new file mode 100644 index 00000000000..42b979333b5 --- /dev/null +++ b/chasm/lib/stream/cursor.go @@ -0,0 +1,134 @@ +package stream + +import ( + "go.temporal.io/api/serviceerror" + "go.temporal.io/server/chasm" + streampb "go.temporal.io/server/chasm/lib/stream/gen/streampb/v1" +) + +// Cursor is a consuming workflow's position in a stream. +// +// It is a subcomponent of the consumer, not of the stream.

What the recorded cursors do give is the input that reassembly needs. + +One implementation detail with a cost attached: both the delivery and completion paths resolve the workflow component **read-only first**, and only take the mutable path when a cursor exists. Reaching it mutably marks the node dirty, which would add a node to the transaction of every workflow in the cluster, subscribed or not. That showed up as a task-generation change in `TestRefreshSubStateMachineTasks` before the read-only check was added. + ### 8.2 What must be recorded, and why empty counts Two rules, both load-bearing: diff --git a/tests/stream_consume_test.go b/tests/stream_consume_test.go new file mode 100644 index 00000000000..c5db451718f --- /dev/null +++ b/tests/stream_consume_test.go @@ -0,0 +1,172 @@ +package tests + +import ( + "testing" + "time" + + "github.com/google/uuid" + "github.com/stretchr/testify/require" + commandpb "go.temporal.io/api/command/v1" + commonpb "go.temporal.io/api/common/v1" + enumspb "go.temporal.io/api/enums/v1" + historypb "go.temporal.io/api/history/v1" + streampb "go.temporal.io/api/stream/v1" + taskqueuepb "go.temporal.io/api/taskqueue/v1" + "go.temporal.io/api/workflowservice/v1" + streamlib "go.temporal.io/server/chasm/lib/stream/gen/streampb/v1" + chasmworkflow "go.temporal.io/server/chasm/lib/workflow" + "go.temporal.io/server/tests/testcore" + "google.golang.org/protobuf/types/known/durationpb" +) + +// Path C: a workflow consuming a stream.

Registering and advancing in the cursor's own transaction is what keeps the two from drifting: a pin lost while its cursor survived would leave truncation free to take a range the cursor still points at. + The interlock covers deliberate truncation. It cannot cover retention expiry on a stream whose consumer outlives it, or out-of-band deletion. If replay finds a recorded range below `base_offset`, the workflow task **fails retryably** with a distinct error rather than raising a nondeterminism error. The distinction matters operationally: a nondeterminism error looks like a code bug and gets triaged as one, while "the stream data this workflow needs is gone" is an infrastructure condition with a different fix.

History records offsets and never payloads, so a task being replayed has to be handed the bytes again from the log, tagged with the event that recorded the range. One response can carry a slice for the task about to run and one per range being replayed, which is why the tag is needed to tell them apart. Also bounded a slice by bytes as well as item count. The first message always goes out however large: held back it would stall the cursor, and an unconsumed range now schedules a workflow task, so the workflow would wake forever without ever receiving anything. --- chasm/lib/stream/config.go | 6 + chasm/lib/stream/messages.go | 26 +++ chasm/lib/stream/messages_test.go | 47 ++++++ go.mod | 2 +- go.sum | 4 +- .../api/recordworkflowtaskstarted/api.go | 13 +- .../stream_slices.go | 151 +++++++++++++++-- streaming-detailed-design.md | 4 +- tests/stream_consume_test.go | 157 ++++++++++++++++-- 9 files changed, 379 insertions(+), 31 deletions(-) create mode 100644 chasm/lib/stream/messages_test.go diff --git a/chasm/lib/stream/config.go b/chasm/lib/stream/config.go index 7e22692a1b7..4d6bf51893e 100644 --- a/chasm/lib/stream/config.go +++ b/chasm/lib/stream/config.go @@ -34,5 +34,11 @@ const ( // delivered on the following task. const MaxConsumeItemsPerTask = 1000 +// MaxConsumeBytesPerTask bounds one Workflow Task's slice by size.

The consumer cannot read another execution's frontier while closing its own transaction, so an append pushes the frontier onto the consumer's cursor and lets that execution's own close decide it owes a workflow task. The pin is registered on the stream before the cursor is written, because the reverse order can leave a cursor no truncation floor protects. The scheduled task is not yet dispatched to a worker, which is the one hop still missing; the test asserts up to the event and fails once it works. --- chasm/lib/stream/cursor.go | 26 ++++- .../gen/streampb/v1/request_response.pb.go | 17 +++- .../stream/gen/streampb/v1/stream_state.pb.go | 44 ++++++++- .../gen/streampb/v1/tasks.go-helpers.pb.go | 37 +++++++ chasm/lib/stream/gen/streampb/v1/tasks.pb.go | 51 +++++++++- .../stream/proto/v1/request_response.proto | 5 +- chasm/lib/stream/proto/v1/stream_state.proto | 13 +++ chasm/lib/stream/proto/v1/tasks.proto | 7 ++ chasm/lib/stream/service/fx.go | 1 + chasm/lib/stream/service/handler.go | 72 ++++++++++++++ chasm/lib/stream/service/library.go | 13 ++- chasm/lib/stream/service/tasks.go | 98 +++++++++++++++++++ chasm/lib/stream/stream.go | 30 +++++- chasm/lib/stream/stream_test.go | 16 +-- chasm/lib/workflow/workflow.go | 71 +++++++++++++- .../stream_slices.go | 32 +++--- streaming-detailed-design.md | 8 +- tests/stream_consume_test.go | 98 +++++++++++++++++++ 18 files changed, 595 insertions(+), 44 deletions(-) diff --git a/chasm/lib/stream/cursor.go b/chasm/lib/stream/cursor.go index 42b979333b5..ce3643e815e 100644 --- a/chasm/lib/stream/cursor.go +++ b/chasm/lib/stream/cursor.go @@ -21,7 +21,10 @@ type Cursor struct { } type NewCursorRequest struct { - StreamID string + StreamID string + // External marks a stream in another execution, whose frontier this + // workflow is told about rather than reads. + External bool CollectionID string BucketSize int64 @@ -51,6 +54,8 @@ func NewCursor(_ chasm.MutableContext, req NewCursorRequest) (*Cursor, error) { CollectionId: req.CollectionID, BucketSize: req.BucketSize, Offset: req.StartOffset, + External: req.External, + KnownHead: req.StartOffset, }, }, nil } @@ -132,3 +137,22 @@ func (c *Cursor) Abandon(_ chasm.MutableContext) { c.State.PendingTo = 0 c.State.HasPending = false } + +// IsExternal reports whether the stream lives in another execution. +func (c *Cursor) IsExternal() bool { + return c.State.External +} + +// KnownHead is the stream's frontier as last pushed to this workflow. +func (c *Cursor) KnownHead() int64 { + return c.State.KnownHead +} + +// AdvanceKnownHead moves the recorded frontier forward.

It Delivery, staging, recording and the cursor advance are built and covered by `tests/stream_consume_test.go`. Two limits are worth naming rather than leaving to be discovered: -**Only a stream in the consuming workflow's own execution can be consumed.** Reading a stream owned by another execution needs that stream's frontier, and the frontier lives on the stream component. Reaching it from inside the consuming workflow's transaction means a cross-execution read while holding the workflow lock, and the CHASM engine is not reachable from `RecordWorkflowTaskStarted` without re-threading it through the history engine. Subscribing to a stream the workflow does not own is rejected rather than silently returning nothing. +**Consuming a stream in another execution is built except for its last hop.** A consumer cannot read another execution's frontier while closing its own transaction, so the frontier is pushed to it instead: an append that leaves a registered external consumer behind schedules a side-effect task on the stream, which writes the new frontier onto that consumer's cursor. That write dirties the consuming execution, and its own transaction close then sees the cursor is behind and schedules a workflow task, which is the same path an owned stream takes. Delivery clips to the pushed frontier rather than a live read, so no cross-execution read happens while a workflow transaction is open. + +The subscription registers the truncation pin on the stream **before** writing the cursor on the workflow. Interrupted after the first write there is a pin holding storage nothing reads, which costs space; the other order would leave a cursor with no pin, and truncation would be free to take a range it still points at. + +What does not work yet is dispatch. The wake reaches History as a `WorkflowTaskScheduled` event and the task never reaches a worker, because a workflow task scheduled from inside a CHASM update is not dispatched. `TestExternalStreamPushSchedulesAWorkflowTask` asserts everything up to that event and fails as soon as the last hop starts working. + +Two consequences worth stating. An external consumer's pin never advances, because advancing it would be a cross-execution write on the workflow task path, so a stream with a live external consumer does not truncate below where that consumer subscribed. And a capped slice relies on the same pushed frontier to continue, so it resumes on the next push rather than immediately. **Replay reassembly is built.** When a workflow task carries History, every `WorkflowTaskCompleted` in it that recorded a range gets its payloads re-read from the log and attached, tagged with that event's id. A response therefore holds at most one untagged slice, for the task about to run, plus one per recorded range being replayed.

Every SDK matches issued commands against command-generated events in order, popping a queue as each event arrives, so a command that produces none leaves its entry at the head and the next event pops the wrong one. TestBufferEvent exists to force new commands to have events, and this design had been opting out of it rather than satisfying it. The cost is one event per subscription, not per message, so the offsets a task consumed still ride WorkflowTaskCompleted and payloads still never enter History. It also means History now explains why a workflow receives stream data, which nothing did before. --- chasm/lib/stream/service/events.go | 45 +++++++++++++ chasm/lib/stream/service/fx.go | 1 + chasm/lib/workflow/stream_commands.go | 67 ++++++++++++++++--- go.mod | 2 +- go.sum | 4 +- .../api/respondworkflowtaskcompleted/api.go | 1 + .../stream_appends.go | 17 +++++ service/history/historybuilder/event_store.go | 3 +- .../historybuilder/history_builder_test.go | 4 +- streaming-detailed-design.md | 14 ++++ tests/stream_consume_test.go | 20 ++++++ 11 files changed, 163 insertions(+), 15 deletions(-) create mode 100644 chasm/lib/stream/service/events.go diff --git a/chasm/lib/stream/service/events.go b/chasm/lib/stream/service/events.go new file mode 100644 index 00000000000..4ef2964ebb2 --- /dev/null +++ b/chasm/lib/stream/service/events.go @@ -0,0 +1,45 @@ +package service + +import ( + enumspb "go.temporal.io/api/enums/v1" + historypb "go.temporal.io/api/history/v1" + "go.temporal.io/server/service/history/hsm" +) + +// streamSubscribedEventDefinition tells the history service how to treat the +// event a subscribe command writes. +// +// It applies nothing.

Publishing still writes none. + +The reason is not cost. Every SDK matches issued commands against command-generated events **in order**, popping a queue as each event arrives (`workflow_machines.rs`, `self.commands.pop_front()`). A command that produces no event leaves its entry at the head of that queue and the next event pops the wrong one. So a command reachable from workflow code has to have an event, and the codebase already says so: `TestBufferEvent` exists to force exactly that, and this design had been opting out of it. + +The cost is per subscription, not per message. A workflow subscribes to a stream once, so this is the same order as a single signal, and it leaves the property the design rests on untouched: the offsets a task consumed still ride `WorkflowTaskCompleted`, and payloads never enter History. Consumption remains zero events per task. + +It also closes an operational gap. Without the event nothing in History explains why a workflow began receiving stream data. + +`AddStreamMessages` is the case where an event would be per batch rather than once, so it still writes none and remains unreachable from workflow code for the same matching reason. That is the trade to revisit with measurements, not by assumption. + +#### Resolution + + + `COMMAND_TYPE_SUBSCRIBE_STREAM` carries only a stream id and a start offset. Everything else the cursor needs is resolved by the server, because a workflow cannot look it up: a stream's collection id is its run id and its bucket size is its own, and reading either means I/O. A value the workflow carried would be a reading rather than a fact, so it could differ on replay. Where the resolution happens is forced by two constraints. The command handler runs under the state lock with nowhere to do I/O from, and by delivery time the cursor has to already exist. So a subscription to a stream in another execution is staged by the handler and resolved in the flush before commit, the same place staged log writes go. A stream the workflow owns needs no resolution and is subscribed in the handler directly. diff --git a/tests/stream_consume_test.go b/tests/stream_consume_test.go index 06829df2f53..28633ee5357 100644 --- a/tests/stream_consume_test.go +++ b/tests/stream_consume_test.go @@ -772,6 +772,16 @@ func TestWorkflowSubscribesToAStreamItself(t *testing.T) { require.Len(t, desc.GetFrontendResponse().GetState().GetConsumers(), 1, "the command must have registered a consumer on the stream") + // The subscription is recorded once, with the offset the server resolved. + // Without it nothing in History explains why this workflow starts receiving + // stream data, and a command that writes no event desynchronises the + // command-to-event matching every SDK's replay depends on. + subscribed := subscribedEvents(env.GetHistory(s.ns, + &commonpb.WorkflowExecution{WorkflowId: id})) + require.Len(t, subscribed, 1) + require.Equal(t, streamID, subscribed[0].GetStreamId()) + require.Equal(t, int64(0), subscribed[0].GetStartOffset()) + // An off-shard producer, with no signal to the workflow. _, err = s.client.AddMessages(s.ctx(), &streamlib.AddMessagesRequest{ FrontendRequest: &streamlib.AddMessagesInput{ @@ -794,3 +804,13 @@ func TestWorkflowSubscribesToAStreamItself(t *testing.T) { require.Len(t, got.GetMessages(), 2) require.Equal(t, "self-1", string(got.GetMessages()[0].GetBody().GetData())) } + +func subscribedEvents(events []*historypb.HistoryEvent) []*historypb.WorkflowStreamSubscribedEventAttributes { + var out []*historypb.WorkflowStreamSubscribedEventAttributes + for _, e := range events { + if attrs := e.GetWorkflowStreamSubscribedEventAttributes(); attrs != nil { + out = append(out, attrs) + } + } + return out +} From ec69563bcfde5fc18f9181ee1215f9fff4cdb054 Mon Sep 17 00:00:00 2001 From: Moe Dashti Date: Fri, 28 Aug 2026 09:25:42 -0400 Subject: [PATCH 40/79] Aligned the stream imports with the repo's alias rules.

It takes `streampb` now, and the file that also needs the generated one aliases that to `streamlib`, the way `stream_commands.go` already did. `deliverStreamSlices` gave up its frontier lookup and its range read to named helpers to get back under the complexity limit. --- chasm/lib/stream/cursor.go | 5 +- chasm/lib/stream/messages.go | 22 ++-- chasm/lib/workflow/workflow.go | 8 +- .../stream_slices.go | 118 +++++++++++------- .../history/historybuilder/event_factory.go | 4 +- .../history/historybuilder/history_builder.go | 4 +- .../history/workflow/mutable_state_impl.go | 4 +- service/matching/wire_compat_test.go | 2 + 8 files changed, 100 insertions(+), 67 deletions(-) diff --git a/chasm/lib/stream/cursor.go b/chasm/lib/stream/cursor.go index ce3643e815e..0355a89f979 100644 --- a/chasm/lib/stream/cursor.go +++ b/chasm/lib/stream/cursor.go @@ -60,8 +60,9 @@ func NewCursor(_ chasm.MutableContext, req NewCursorRequest) (*Cursor, error) { }, nil } -// A cursor lives as long as the workflow holding it.

Publishing was the last stream command producing no event, which kept it unreachable from every SDK: sdk-core matches commands to events by position, so a command with no event puts replay out of step. The event names the offset range and nothing else, so it costs 41 bytes whether the batch holds one 20-byte message or a thousand 2KB ones. The Signal it replaces costs 112 bytes for the first and 2KB for each of the rest. --- chasm/lib/stream/service/events.go | 37 ++- chasm/lib/workflow/stream_commands.go | 75 ++++- go.mod | 2 +- go.sum | 4 +- service/history/historybuilder/event_store.go | 3 +- .../historybuilder/history_builder_test.go | 6 +- tests/stream_publish_cost_test.go | 289 ++++++++++++++++++ tests/stream_workflow_test.go | 30 +- 8 files changed, 423 insertions(+), 23 deletions(-) create mode 100644 tests/stream_publish_cost_test.go diff --git a/chasm/lib/stream/service/events.go b/chasm/lib/stream/service/events.go index 4ef2964ebb2..0088b1eec5e 100644 --- a/chasm/lib/stream/service/events.go +++ b/chasm/lib/stream/service/events.go @@ -38,8 +38,41 @@ func (streamSubscribedEventDefinition) CherryPick( return hsm.ErrNotCherryPickable } -// RegisterEventDefinitions makes the subscription event known to the history +// streamMessagesAddedEventDefinition tells the history service how to treat +// the event a publish command writes. +// +// Like the subscription event it applies nothing: the stream's frontier is +// CHASM state committed with the workflow task, and the bodies are in the +// stream's own log.

A stream a workflow owns is a subcomponent of that execution, so it has no id of its own and the id-addressed read could not reach it. Publishing from a workflow was therefore write-only from anywhere else, which rules out the case the feature exists for: an agent emits tokens and a UI reads them. It is addressed by its owner and its name instead, and routed on the owner so the call lands on the shard that holds both the frontier and the log. A stream the workflow has not published to yet reads as an empty one rather than as an error, because a reader arriving before the first event is ordinary and a parked reader has to wake when the stream appears. --- .../v1/request_response.go-helpers.pb.go | 222 ++++++ .../gen/streampb/v1/request_response.pb.go | 704 ++++++++++++++---- .../lib/stream/gen/streampb/v1/service.pb.go | 86 ++-

A workflow brackets a turn, but the tokens come from the activity making the model call, and an activity has no Workflow Task to ride. Both producers now write one ordered log: the workflow inside its own commit, at no transition cost, and everything else in a transition of its own per batch. Creating the stream is what the first append from outside has to pay for, because the collection id and bucket size it writes under are decided then. Only the first one pays it. --- .../v1/request_response.go-helpers.pb.go | 111 ++++ .../gen/streampb/v1/request_response.pb.go | 565 ++++++++++++------ .../lib/stream/gen/streampb/v1/service.pb.go |

A stream log takes writes from a workflow task and from producers outside it, and the two drew transaction ids from unrelated sequences. The store resolves a contested node by keeping the highest id it has seen and dropping everything below, so two sequences on one log lose data rather than order it: a node left by a write that never committed outranks every later write numbered below it, and the reader is not told, it just stops seeing new messages. Both producers now number from the shard. Ids only increase, so an uncommitted node is superseded rather than dominant, and two attempts of one workflow task can no longer land on the same key, which the design required from the start and the event-id derivation could not give. The staged flush is skipped once the task has failed, so a task that will not advance the frontier writes no bytes at all. The renumbering against already-read state is gone from the external paths: that state can be stale by commit time, so it protected nothing, and two writers that both took it would collide. Found by an outside review. The suite could not see it because SQLite resolves a repeated key with REPLACE, where MySQL and Postgres fail the write. --- .gitignore | 3 + chasm/lib/stream/service/handler.go | 16 ++++-- chasm/lib/workflow/registry.go | 23 ++++++-- chasm/lib/workflow/stream_commands.go | 33 +++-------- .../tests/history_store_stream_log.go | 57 +++++++++++++++++++ .../api/respondworkflowtaskcompleted/api.go | 21 ++++--- .../workflow_task_completed_handler.go | 2 +- 7 files changed, 112 insertions(+), 43 deletions(-) diff --git a/.gitignore b/.gitignore index 8bf274759e4..c8268bd4347 100644 --- a/.gitignore +++ b/.gitignore @@ -51,3 +51,6 @@ # Compiled output of develop/streamdemo. /streamdemo + +# Review scaffolding, kept out of the repo +/prompt.txt diff --git a/chasm/lib/stream/service/handler.go b/chasm/lib/stream/service/handler.go index 040f85b525a..2569e92b9f8 100644 --- a/chasm/lib/stream/service/handler.go +++ b/chasm/lib/stream/service/handler.go @@ -221,13 +221,15 @@ func (h *handler) AddMessages( return nil, err } + // Straight from the shard, never adjusted against the state just read. + // That state can be stale by the time this commits, so renumbering against + // it protects nothing, and two writers that both renumbered would land on + // the same id.

Two defects an outside review found, unrelated except that both were invisible to the tests. A stream's log rows carried a cleanup tag the history scavenger read as a workflow identity. It looked the namespace up, found none, took the branch for garbage and deleted it. On by default, sixty days old by default, so a live stream would lose everything past that. Branches that are not an execution's history now say so, and the scavenger leaves them to whoever wrote them. The subscribe event was written in the flush, which runs after every command, so it landed behind the events of commands issued later. Every SDK matches issued commands against their events by position, so a workflow that subscribed and then did anything else in the same task would fail its first replay. The event is now written where the command is, and the flush fills in the start offset it could not know yet. Only the tests subscribing last kept this hidden. --- chasm/lib/stream/log.go | 8 +- chasm/lib/workflow/stream_commands.go | 29 +++++-- chasm/lib/workflow/stream_cursor_test.go | 70 +++++++++++++---- chasm/lib/workflow/workflow.go | 4 + common/persistence/data_interfaces.go | 17 ++++ .../stream_appends.go | 14 ++-- service/worker/scanner/history/scavenger.go | 12 +++ .../worker/scanner/history/scavenger_test.go | 58 ++++++++++++++ tests/stream_consume_test.go | 78 +++++++++++++++++++ 9 files changed, 260 insertions(+), 30 deletions(-) diff --git a/chasm/lib/stream/log.go b/chasm/lib/stream/log.go index 02566c10d2e..af89484d7e5 100644 --- a/chasm/lib/stream/log.go +++ b/chasm/lib/stream/log.go @@ -107,8 +107,12 @@ func WriteAppend( TransactionID: op.TxnID, PrevTransactionID: op.PrevTxnID, IsNewBranch: op.IsNewBucket, - Info: fmt.Sprintf("stream:%s:%s", namespaceID, collectionID), - History: op.Blob, + // Prefixed so the history scavenger leaves it alone.

The frontier push resolves each consumer through the local shard controller, so a consumer whose shard lives on another host fails every time. Its known head never advances, delivery clips to it, and the workflow simply never receives anything. That was logged at warning level per consumer and then dropped, which is why a single-host test cluster showed nothing. Retrying does not make it work across hosts.

Registering a consumer pin and telling a consumer the frontier moved both resolved refs through the local shard controller, which refuses a shard this host does not own. Both are now RPCs on the stream service, routed on the execution they act upon, so they land wherever it lives. The pin still goes on before the cursor, because the routed call returns before the local update runs, so the ordering that guarantee rests on is unchanged. The third step cannot be done this way. A subscribe issued from workflow code registers its pin inside the workflow task's own transaction, and a cross-shard call cannot live there. Moving it out makes the pin asynchronous and gives up the ordering.

A `SubscribeStream` command cannot resolve anything itself, because +a command handler runs under the state lock with nowhere to do I/O from, so the +command stages and the flush resolves. The flush registers the pin on the +stream and then writes the cursor onto the workflow, in that order, inside the +transaction that commits the workflow task. + +That order is the guarantee. Interrupted between the two there is a pin holding +storage nothing reads, which costs space and is reclaimable. The other order +would leave a cursor with no pin behind it, and truncation would be free to take +a range that cursor still points at, which loses data a consumer was promised. + +A synchronous cross-shard call cannot live there. The workflow's transaction is +open, it holds the execution lock, and the far shard may be on another host. So +the pin has to move out of the transaction, and the moment it does, the ordering +that made the guarantee is gone. + +## Why the obvious answers do not work + +**Emit a transfer task that registers the pin.** This is how signalling an +external workflow works, and it is the shape the rest of Temporal uses. It makes +the pin asynchronous: the workflow task commits with a cursor, and the pin +arrives later. Between the two, truncation can take the range the cursor points +at. That is precisely the failure the current order exists to prevent, now with +a wider window. + +**Register the pin before the workflow task commits, from outside.** There is +nothing outside to do it. The subscribe originates in workflow code, and the +first moment the server knows about it is the command. + +**Have the command handler do the I/O.** It cannot. That constraint is what +produced the staging design in the first place. + +**Make truncation defensive: never truncate below any cursor, pin or not.** +Truncation cannot see cursors it does not have a pin for. The pin is how a +consumer in another execution becomes visible to the stream at all. + +## Directions worth costing + +1. **A cursor that is not usable until its pin is confirmed.** The workflow task + commits a cursor in a pending state that delivers nothing. A transfer task + registers the pin and then marks the cursor live. Truncation ignores pending + cursors, so it can still take the range, but a pending cursor that finds its + start offset already truncated fails the subscription cleanly rather than + silently skipping data. Cost: a state on the cursor, a task, and a visible + failure mode for a subscription that was too slow to pin. + +2. **Pin first, from the frontend, before the command is issued.** Move + subscribe out of workflow code and make it something a client does, the way + `SubscribeWorkflow` already is for external callers. The workflow then only + reads. This removes the problem rather than solving it, at the cost of the + ergonomics: a workflow can no longer subscribe to a stream by itself. + +3. **A reservation with a lease.** The command handler cannot do I/O, but the + flush can, and the flush is still inside the transaction. A short-lived + reservation written locally, honoured by truncation for its lease duration, + converted to a real pin by a transfer task. Cost: truncation has to consult + something with a clock, which it currently does not. + +4. **Let the substrate decide it.** If the log moves to a dedicated table keyed + by `(shard, collection, offset)`, the pin and the cursor may be able to live + in one place and the ordering question dissolves. This is the argument for + settling the substrate before spending anything here. + +## Recommendation + +Do not build any of these yet. The cheapest correct thing today is to say that +Path C across executions is single-host only, which is now true and visible +rather than true and silent. Direction 1 is the one to cost first if Path C has +to work across hosts before the substrate is settled, and direction 4 is the +reason not to start.

Per-partition cost was the biggest named risk to a Temporal-owned stream and had never been run. It has been now, on the schema a dedicated facet would use. Cassandra is not the obstacle it was feared to be: a 100k-token session is 5.84 MB, well inside guidance. Row count binds before size does, so buckets should be sized against the unbatched case, around 10,000 offsets rather than the 100,000 in use. It also found a gap that applies to the current substrate just as much: a bucket has an offset budget and no byte budget, so a stream of large batches can build a partition twice the guidance out of cells that are themselves too big. A bucket has to roll on whichever budget is reached first. And it measured a reason to move that is not about correctness. Keying a row by the offset its batch starts at positions a read in one row. The node-id mapping cannot, so it reads back up to a full batch of rows before the target on every poll, for every reader. --- develop/cassmeasure/gen.py | 49 ++++++++++++++ develop/cassmeasure/reads.cql | 11 ++++ streaming-cassandra-partitioning.md | 99 +++++++++++++++++++++++++++++ 3 files changed, 159 insertions(+) create mode 100644 develop/cassmeasure/gen.py create mode 100644 develop/cassmeasure/reads.cql create mode 100644 streaming-cassandra-partitioning.md diff --git a/develop/cassmeasure/gen.py b/develop/cassmeasure/gen.py new file mode 100644 index 00000000000..e33711c86de --- /dev/null +++ b/develop/cassmeasure/gen.py @@ -0,0 +1,49 @@ +"""Generate the CQL for the Option B stream-log partition measurement. + +Three shapes, each in its own partition so tablestats can tell them apart: + A 100k rows of 40 bytes an unbatched token stream, one bucket of 100k offsets + B 100 rows of 2 MB the largest batch the current design permits + C 50k rows of 200 bytes a modestly batched stream +""" +import sys + +NS = "11111111-1111-1111-1111-111111111111" + +def rows(bucket, count, payload_bytes, offset_per_row=1): + blob = "0x" + ("ab" * payload_bytes) + out = [] + off = 0 + for _ in range(count): + out.append( + f"INSERT INTO stream_log (shard_id, namespace_id, collection_id, bucket, " + f"start_offset, end_offset, data, data_encoding) VALUES " + f"(1, {NS}, 'c1', {bucket}, {off}, {off + offset_per_row}, {blob}, 'Proto3');" + ) + off += offset_per_row + return out + +print(""" +CREATE KEYSPACE IF NOT EXISTS streammeasure WITH replication = + {'class': 'SimpleStrategy', 'replication_factor': 1}; +USE streammeasure; +DROP TABLE IF EXISTS stream_log; +CREATE TABLE stream_log ( + shard_id int, + namespace_id uuid, + collection_id text, + bucket bigint, + start_offset bigint, + end_offset bigint, + data blob, + data_encoding text, + PRIMARY KEY ((shard_id, namespace_id, collection_id, bucket), start_offset) +) WITH CLUSTERING ORDER BY (start_offset ASC); +""") + +shape = sys.argv[1] +if shape == "A": + print("\n".join(rows(bucket=0, count=100000, payload_bytes=20))) +elif shape == "B": + print("\n".join(rows(bucket=1, count=50, payload_bytes=512 * 1024, offset_per_row=1000))) +elif shape == "C": + print("\n".join(rows(bucket=2, count=50000, payload_bytes=100))) diff --git a/develop/cassmeasure/reads.cql b/develop/cassmeasure/reads.cql new file mode 100644 index 00000000000..afbedc1c908 --- /dev/null +++ b/develop/cassmeasure/reads.cql @@ -0,0 +1,11 @@ +USE streammeasure; +TRACING ON; +-- Find the batch containing an arbitrary offset: reverse slice, one row. +SELECT start_offset, end_offset FROM stream_log + WHERE shard_id=1 AND namespace_id=11111111-1111-1111-1111-111111111111 + AND collection_id='c1' AND bucket=0 AND start_offset <= 73456 + ORDER BY start_offset DESC LIMIT 1; +-- Read forward from there for a page. +SELECT start_offset, end_offset FROM stream_log + WHERE shard_id=1 AND namespace_id=11111111-1111-1111-1111-111111111111 + AND collection_id='c1' AND bucket=0 AND start_offset >= 73456 LIMIT 100; diff --git a/streaming-cassandra-partitioning.md b/streaming-cassandra-partitioning.md new file mode 100644 index 00000000000..a498a5a95f0 --- /dev/null +++ b/streaming-cassandra-partitioning.md @@ -0,0 +1,99 @@ +# Cassandra partitioning for the stream log + +Measured 2026-09-02 against Cassandra 5.0.9, single node, on the schema the +dedicated-facet substrate would use.

From c272bbb33b693b47e724bc07c7de0a10be2bcf85 Mon Sep 17 00:00:00 2001 From: Moe Dashti Date: Wed, 2 Sep 2026 11:19:41 -0400 Subject: [PATCH 59/79] Moved the stream log onto a table of its own. The log lived in history_node, which was the fastest substrate to prototype on and the wrong one to keep. Its contested-node rule is written for one writer per branch, its rows look like workflow history to anything that inspects them, and its replication path runs through version histories a stream has none of. Three of the six blocking defects an outside review found came from that choice. A row is now keyed by the offset its batch starts at. That single change is what the substrate is for: a write is idempotent, a retry addresses the row it wrote before, and there is nothing for an uncommitted write to outrank. The frontier the stream component commits is the only thing deciding what a reader may see, which is what the design always said and could not previously rely on. It also positions in one row. Finding the batch holding an arbitrary offset is an indexed lookup rather than reading a full batch of rows backwards on every poll, which is measured in streaming-cassandra-partitioning.md. SQLite, MySQL, Postgres and Cassandra all implement it, and the Cassandra DDL is validated against a running server. Only SQLite is exercised by tests here. The whole stream functional suite passes unchanged, which is the point: this moves where the bytes live and nothing else. The transaction id is now vestigial and still threaded through the component. Removing it is a follow-up, kept separate so this change stays reviewable. --- chasm/lib/stream/log.go | 149 ++++++------------ chasm/lib/stream/stream.go | 6 +- chasm/lib/stream/stream_test.go | 16 +- common/metrics/metric_defs.go | 6 + common/persistence/cassandra/history_store.go | 99 ++++++++++++ common/persistence/data_interfaces.go | 7 + common/persistence/data_interfaces_mock.go | 43 +++++ common/persistence/history_manager.go | 26 +++ common/persistence/persistence_interface.go | 52 ++++++ .../persistence/persistence_metric_clients.go | 42 +++++ .../persistence_rate_limited_clients.go | 33 ++++ .../persistence_retryable_clients.go | 37 +++++ common/persistence/sql/history_store.go | 83 ++++++++++ .../persistence/sql/sqlplugin/interfaces.go | 1 + .../sql/sqlplugin/mysql/stream_log.go | 64 ++++++++ .../sql/sqlplugin/postgresql/stream_log.go | 65 ++++++++ .../sql/sqlplugin/sqlite/stream_log.go | 72 +++++++++ .../persistence/sql/sqlplugin/stream_log.go | 66 ++++++++ .../tests/history_store_stream_log.go | 83 ++++++++-- schema/cassandra/temporal/schema.cql | 15 ++ .../versioned/v1.10/add_stream_log.cql | 14 ++ .../temporal/versioned/v1.10/manifest.json | 6 +- schema/sqlite/v3/temporal/schema.sql | 12 ++ .../versioned/v0.10/add_stream_log.sql | 12 ++ .../v3/temporal/versioned/v0.10/manifest.json | 4 +- tests/testcore/history_task_recorder.go | 24 +++ 26 files changed, 899 insertions(+), 138 deletions(-) create mode 100644 common/persistence/sql/sqlplugin/mysql/stream_log.go create mode 100644 common/persistence/sql/sqlplugin/postgresql/stream_log.go create mode 100644 common/persistence/sql/sqlplugin/sqlite/stream_log.go create mode 100644 common/persistence/sql/sqlplugin/stream_log.go create mode 100644 schema/cassandra/temporal/versioned/v1.10/add_stream_log.cql create mode 100644 schema/sqlite/v3/temporal/versioned/v0.10/add_stream_log.sql diff --git a/chasm/lib/stream/log.go b/chasm/lib/stream/log.go index af89484d7e5..f458b56b68c 100644 --- a/chasm/lib/stream/log.go +++ b/chasm/lib/stream/log.go @@ -2,11 +2,9 @@ package stream import ( "context" - "fmt" "github.com/google/uuid" commonpb "go.temporal.io/api/common/v1" - persistencespb "go.temporal.io/server/api/persistence/v1" "go.temporal.io/server/common/persistence" ) @@ -38,12 +36,13 @@ const defaultReadPageSize = 256 // two apart is what lets the append ride a workflow's own commit later without // the component knowing. type LogAppend struct { - Bucket int64 - NodeID int64 - TxnID int64 - PrevTxnID int64 + Bucket int64 + // The offsets this batch covers, end exclusive.

The floor waited for the slowest reader so that a consumer could always re-read a range its history recorded. Nothing released it when that consumer finished, so a stream with a cap kept everything for as long as a consumer had ever been registered. It was not protecting readers, it was disabling the cap. Registering a consumer now says who to wake and nothing more, and truncation applies the cap it was asked for. A consumer that falls behind is told: the polling path already refused a read below the base, and delivery now does too. Delivery used not to, which was the real hazard, because it would have handed the workflow whatever survived and left a hole nothing could see. This also removes the reason subscribing from workflow code had to reach another shard while holding the execution lock. That was the last of the three cross-execution steps and the one that could not be routed, so it stops being a problem rather than being solved with machinery. Six tests asserted the old floor. They assert the new behaviour instead, since what changed is a guarantee and not an implementation. --- chasm/lib/stream/stream.go | 33 +++-- chasm/lib/stream/stream_test.go | 56 +++---- chasm/lib/workflow/stream_cursor_test.go | 81 ++++++---- .../stream_slices.go | 10 ++ streaming-open-question-pin-ordering.md | 138 ++++++++---------- 5 files changed, 163 insertions(+), 155 deletions(-) diff --git a/chasm/lib/stream/stream.go b/chasm/lib/stream/stream.go index 56f5e357e96..1aad73462ee 100644 --- a/chasm/lib/stream/stream.go +++ b/chasm/lib/stream/stream.go @@ -55,7 +55,6 @@ type AddMessagesRequest struct { // Optional fencing.

A transfer task - registers the pin and then marks the cursor live. Truncation ignores pending - cursors, so it can still take the range, but a pending cursor that finds its - start offset already truncated fails the subscription cleanly rather than - silently skipping data. Cost: a state on the cursor, a task, and a visible - failure mode for a subscription that was too slow to pin. - -2. **Pin first, from the frontend, before the command is issued.** Move - subscribe out of workflow code and make it something a client does, the way - `SubscribeWorkflow` already is for external callers. The workflow then only - reads. This removes the problem rather than solving it, at the cost of the - ergonomics: a workflow can no longer subscribe to a stream by itself. - -3. **A reservation with a lease.** The command handler cannot do I/O, but the - flush can, and the flush is still inside the transaction. A short-lived - reservation written locally, honoured by truncation for its lease duration, - converted to a real pin by a transfer task. Cost: truncation has to consult - something with a clock, which it currently does not. - -4. **Let the substrate decide it.** If the log moves to a dedicated table keyed - by `(shard, collection, offset)`, the pin and the cursor may be able to live - in one place and the ordering question dissolves. This is the argument for - settling the substrate before spending anything here. - -## Recommendation - -Do not build any of these yet. The cheapest correct thing today is to say that -Path C across executions is single-host only, which is now true and visible -rather than true and silent. Direction 1 is the one to cost first if Path C has -to work across hosts before the substrate is settled, and direction 4 is the -reason not to start. +So the pin is gone. Registering a consumer says who to wake when the frontier +moves, and nothing more. Truncation applies the cap it was asked for. + +A consumer that falls behind the floor is told. On the polling path that was +already true: a read below the base returns an error naming where the stream +now starts. The delivery path now does the same, and used not to, which was the +real hazard: it would have read whatever survived and handed the workflow a +range with a hole in it that nothing could see. + +This is what a log with a retention window does everywhere else. A reader that +cannot keep up gets an out-of-range error rather than silent loss, and the +window is the thing the operator asked for. + +## What this costs + +A workflow consuming a capped stream can now be outrun and fail. Before, it +could not be outrun, because the cap did not work. The failure is explicit, it +names the offsets, and it happens when the workflow next tries to read. + +For a stream with no cap and no retention, nothing changes: there is no floor +to fall behind. + +## What it buys, beyond the cap working + +The cross-execution write disappears from the workflow-task transaction, which +is what made this a design question rather than plumbing. Subscribing from +workflow code no longer has to reach another shard while holding the execution +lock, so the last of the three cross-execution steps stops being a problem +rather than being solved with machinery. + +## What is still not settled + +Registering a consumer still happens in the flush, and still reaches the +stream's shard. That is now a call whose failure costs a delayed wake-up rather +than a lost pin, so it can be retried or deferred without risking data. Making +it asynchronous is a tidy-up, not a correctness fix, and is not done. From 343d19d93d4571e7e02a90c658beb3ca2dd2f4f3 Mon Sep 17 00:00:00 2001 From: Moe Dashti Date: Wed, 2 Sep 2026 12:04:16 -0400 Subject: [PATCH 62/79] Designed stream log replication, which the substrate change made cheap. The component's state already replicates: a stream's frontier and cursors are CHASM nodes and ride the sync-versioned-transition message. Only the log rows do not, and on the old substrate there was nowhere to put them, because replication reads history through version histories a stream had none of. Keying a row by the offset its batch starts at changes that. Applying a row is idempotent, rows are independent, and a row says which offsets it covers, so the payload can be shipped rather than fetched back the way history events are. Carrying the rows in the message that already carries the frontier removes the ordering question instead of answering it. Split them and the frontier can arrive first, leaving a standby holding offsets whose bytes never landed, found at failover. Not built. What needs deciding first is bigger than the mechanism: a size cap on the most important message in the replication path, and what happens to a stream written from both sides of a failover, which idempotent-by-offset turns into silent last-writer-wins. --- streaming-replication-design.md | 98 +++++++++++++++++++++++++++++++++ 1 file changed, 98 insertions(+) create mode 100644 streaming-replication-design.md diff --git a/streaming-replication-design.md b/streaming-replication-design.md new file mode 100644 index 00000000000..a540bd46168 --- /dev/null +++ b/streaming-replication-design.md @@ -0,0 +1,98 @@ +# Replicating a stream log + +Status: designed, not built.

They ride along for +free. + +The log does not. Its rows live in `stream_log`, outside the CHASM tree, and +nothing ships them. That is the whole of the gap: after a failover the standby +holds a frontier and no bytes, so every read fails and every subscribed +workflow wedges. + +This was previously worse than a gap. On the old substrate there was no hook to +build either, because replication reads history through a workflow's version +histories and a stream's buckets appeared in none. There was nowhere to put the +rows even if you wanted to. + +## Why the substrate change makes it cheap + +Three properties, all of them consequences of keying a row by the offset its +batch starts at. + +**Applying a row is idempotent.** The key is `(shard, namespace, collection, +bucket, start_offset)`, so writing the same row twice is a no-op and writing a +retried version of it replaces the first. A replication stream may therefore +duplicate, retry, and redeliver freely. None of the exactly-once machinery +history events need applies here. + +**Rows are independent.** There is no chain, no previous-transaction pointer, +nothing that orders one row against another. Out-of-order arrival is harmless. + +**A row is self-describing.** It carries the offsets it covers, so a receiver +needs no context to place it. + +Together those mean the payload can be shipped rather than referenced. History +events are fetched back by the standby through branch tokens, which is most of +the complexity in that path, and it exists because events are large and shared +across branches. Stream batches are neither. + +## The design + +Carry the rows in the message that already carries the frontier. + +`SyncVersionedTransition` is built from everything that changed since the +receiver's last known version. A stream's appends are part of what changed. Add +the rows for the offset range between the last replicated offset and the +current frontier to that message, alongside `UpdatedChasmNodes`. + +The apply side writes the rows first, then applies the state. Both are +idempotent, so a failure between them replays harmlessly. + +**Ordering comes free, and it is the thing most likely to be got wrong.** If the +rows travelled separately from the frontier, the frontier could arrive first and +the standby would hold a frontier covering offsets whose bytes have not landed: +exactly the hole this whole design exists to avoid, revealed at failover, which +is the worst possible moment. Putting them in one message removes the question +rather than answering it. Any design that separates them needs a per-collection +replicated-through watermark and reads clamped to `min(frontier, watermark)`, +which is more machinery to get a worse result. + +## What has to be decided before building + +**Message size.** A stream can append a great deal between two syncs, and +`sync_state_retriever` has no byte cap today. Attaching log rows changes the +size profile of the most important message in the replication path. It needs a +cap and a continuation, and whether that belongs here or in the sync path +generally is not my call to make alone. + +**Conflict on a stream written from both sides.** Unresolved, and not made +better by any of the above. Two clusters appending to one stream will assign the +same offsets to different bytes, and idempotent-by-offset then means last writer +wins, silently. The honest options are to make a stream single-writer by +ownership, the way an execution already is, or to accept the loss and say so. +Ownership is the right answer and it is a design question of its own. + +**Whether streams replicate at all in the first release.** A stream that does +not replicate is not a correctness bug if it is documented; it is a smaller +feature. Given the option is still competing against one that keeps the payload +outside Temporal entirely, shipping without replication and saying so may be the +right first step. + +## Estimate + +The mechanism above is perhaps a week: proto, retrieval, apply, and the xdc +tests to prove a failover keeps the bytes. The size cap and the single-writer +question are each larger than the mechanism, and both are decisions rather than +code. + +I have not started it.

The note designed a private replication protocol for the stream log. The reason it needed one is that CHASM has no way for a component to own data it does not store inline, so the framework does not know the bytes exist and cannot replicate, reclaim or account for them. History solved this bespoke with branch tokens. Asking for the general version is the right order, since building the private one first makes it harder to ask. Reframed on the assumption that the store is external and shared rather than the execution database. That assumption removes any chance of the framework reaching the bytes through an existing persistence path, and it puts the current interface in the wrong place: the three methods sit on ExecutionStore, which presumes the log is shard-local. --- chasm-external-data-request.md | 166 ++++++++++++++++++++++++++++++++ streaming-replication-design.md | 123 ----------------------- 2 files changed, 166 insertions(+), 123 deletions(-) create mode 100644 chasm-external-data-request.md delete mode 100644 streaming-replication-design.md diff --git a/chasm-external-data-request.md b/chasm-external-data-request.md new file mode 100644 index 00000000000..9e41b21bd3a --- /dev/null +++ b/chasm-external-data-request.md @@ -0,0 +1,166 @@ +# CHASM needs a node kind for data a component owns but does not store inline + +Audience: CHASM owners.

That part is not controversial and it is what +history already does: the branch token lives in mutable state, the bytes live +in `history_node`. The gap is that history's arrangement is bespoke. There is +no general way to express it, so the next component to need it starts over. + +## Working assumption: the store is external and shared + +For the streaming prototype the current implementation is a `stream_log` table +in the execution database, but **the intended target is an external shared +store**, not Temporal's own database. That is the right assumption for this +request, and it sharpens it: the locator points outside the database entirely, +so there is no chance of the framework quietly reaching the bytes through an +existing persistence path. It has to be told. + +It also surfaces the one thing the current prototype has in the wrong place: +`AppendStreamLog`, `ReadStreamLog` and `DeleteStreamLogBucket` are methods on +`ExecutionStore` (`persistence_interface.go:168-175`), implemented in +`sql/history_store.go` and `cassandra/history_store.go`. That presumes the log +lives in the execution database. Under an external store it needs to be its own +store type, resolved per namespace or per cluster rather than per shard. + +Two consequences of an external store that this design has to answer, and they +are worth being explicit about because they are not improvements: + +**There is no transaction across the two systems.** The bytes and the frontier +commit separately. Ordering is therefore load-bearing: write bytes, then commit +the frontier. Crashing in between leaves bytes nobody references, which is +reclaimable garbage. The reverse order leaves a frontier whose bytes never +landed, which is unrecoverable data loss discovered by a reader. Idempotent +writes keyed by offset make the safe order safe to retry. + +**Durability has to be real.** Redis has been named as a candidate. Its default +configuration is not durable, and a stream that a customer is told is durable +cannot be backed by a cache. Whatever the store is, it needs durable +acknowledgement before the frontier advances, or the ordering rule above buys +nothing. + +## What the framework would have to do + +**Replicate.** Component state already replicates: `sync_state_retriever.go:415` +ships `UpdatedChasmNodes` inside `SyncWorkflowStateMutationAttributes`, scoped +by `exclusive_start_versioned_transition`. External bytes do not, so today a +standby holds a frontier and no data, discovered at failover. + +Whether the framework has to ship the bytes at all depends on the store, and +this is the one question an external store genuinely improves. If the store is +itself multi-region, replication of the payload is the store's problem and +Temporal ships only the reference, which it already does. If the store is +regional, Temporal ships the payload, and now two systems have to fail over +consistently. The framework should therefore treat "who replicates the bytes" +as a property of the store rather than assuming either answer. + +**Reclaim.** When the owning component completes or truncates, something has to +delete the bytes. Inline data gets this free. External data needs the framework +to run a reclamation hook, and to tolerate the store having already lost them. + +**Account.** External bytes are invisible to `approximateSize`, which is correct +for the force-terminate check and wrong for quota. A namespace can currently +write unbounded external payload with no accounting anywhere. + +## A protocol that works + +For the regional-store case, where Temporal does ship the payload. Offered as a +concrete proposal rather than the only option. + +Three properties make shipping the payload viable rather than fetching it back +the way history events are fetched through branch tokens. All three follow from +keying a record by the offset it starts at: + +- **Applying is idempotent.** Same key, same record.

Both are idempotent, so a failure in between replays +harmlessly. Ordering is then free, which matters because it is the thing most +likely to be got wrong: shipped separately, the frontier can arrive first and +the standby holds offsets whose bytes never landed. + +**Which records to ship** is the part with a real choice in it. The state delta +is versioned and the records are not, so the sender cannot tell from what +already exists which records go with it. + +*Receiver reports a watermark.* The standby says, per collection, the offset it +holds records through, and the sender ships from there to the frontier.

That is the correct design for state. It is -not a place to put payload: +A stream's messages cannot live in mutable state.

Inline, that is one long +agent conversation past the warn and approaching the limit, and every append rewrites the whole record on the way there. -So the bytes go in a side store. That part is not controversial and it is what -history already does: the branch token lives in mutable state, the bytes live -in `history_node`. The gap is that history's arrangement is bespoke. There is -no general way to express it, so the next component to need it starts over. - -## Working assumption: the store is external and shared - -For the streaming prototype the current implementation is a `stream_log` table -in the execution database, but **the intended target is an external shared -store**, not Temporal's own database. That is the right assumption for this -request, and it sharpens it: the locator points outside the database entirely, -so there is no chance of the framework quietly reaching the bytes through an -existing persistence path. It has to be told. - -It also surfaces the one thing the current prototype has in the wrong place: -`AppendStreamLog`, `ReadStreamLog` and `DeleteStreamLogBucket` are methods on -`ExecutionStore` (`persistence_interface.go:168-175`), implemented in -`sql/history_store.go` and `cassandra/history_store.go`. That presumes the log -lives in the execution database. Under an external store it needs to be its own -store type, resolved per namespace or per cluster rather than per shard. - -Two consequences of an external store that this design has to answer, and they -are worth being explicit about because they are not improvements: - -**There is no transaction across the two systems.** The bytes and the frontier -commit separately. Ordering is therefore load-bearing: write bytes, then commit -the frontier. Crashing in between leaves bytes nobody references, which is -reclaimable garbage. The reverse order leaves a frontier whose bytes never -landed, which is unrecoverable data loss discovered by a reader. Idempotent -writes keyed by offset make the safe order safe to retry. - -**Durability has to be real.** Redis has been named as a candidate. Its default -configuration is not durable, and a stream that a customer is told is durable -cannot be backed by a cache. Whatever the store is, it needs durable -acknowledgement before the frontier advances, or the ordering rule above buys -nothing. - -## What the framework would have to do - -**Replicate.** Component state already replicates: `sync_state_retriever.go:415` -ships `UpdatedChasmNodes` inside `SyncWorkflowStateMutationAttributes`, scoped -by `exclusive_start_versioned_transition`. External bytes do not, so today a -standby holds a frontier and no data, discovered at failover. - -Whether the framework has to ship the bytes at all depends on the store, and -this is the one question an external store genuinely improves. If the store is -itself multi-region, replication of the payload is the store's problem and -Temporal ships only the reference, which it already does. If the store is -regional, Temporal ships the payload, and now two systems have to fail over -consistently. The framework should therefore treat "who replicates the bytes" -as a property of the store rather than assuming either answer. - -**Reclaim.** When the owning component completes or truncates, something has to -delete the bytes. Inline data gets this free. External data needs the framework -to run a reclamation hook, and to tolerate the store having already lost them. - -**Account.** External bytes are invisible to `approximateSize`, which is correct -for the force-terminate check and wrong for quota. A namespace can currently -write unbounded external payload with no accounting anywhere. - -## A protocol that works - -For the regional-store case, where Temporal does ship the payload. Offered as a -concrete proposal rather than the only option. - -Three properties make shipping the payload viable rather than fetching it back -the way history events are fetched through branch tokens. All three follow from -keying a record by the offset it starts at: - -- **Applying is idempotent.** Same key, same record. Duplicate and retry freely. -- **Records are independent.** No chain, no previous-record pointer, so - out-of-order arrival is harmless. -- **A record is self-describing.** It carries the range it covers, so a receiver - needs no context to place it. +## Prior art, which reached the same ceiling + +Dan Davison and Sean Kane built a CHASM streaming component about a year ago, +on `seandan/streaming` in `temporalio/temporal`. It is roughly 1500 lines under +the same `chasm/lib/stream/` path this prototype uses, with `AddToStream` and +`PollStream` on the frontend and one end-to-end test. Its component is: + +```go +type Stream struct { + chasm.UnimplementedComponent + *streampb.StreamState // head, tail + Messages chasm.Map[int64, *commonpb.Payload] // one data node per message +} +``` + +Roey Berman flagged its ceiling at the time: limited to about 5 MB of total +payload because everything is in mutable state. The same note enumerated three +ways out, and they are the same three this prototype arrived at independently: +CHASM nodes in separate cells, payloads written outside mutable state by +repurposing history, or payloads replaced by pointers to a blob store. + +Worth being plain about it: this prototype's first substrate was the second of +those, and the request this file used to make was the third. Neither was a new +idea. Finding that out after the fact is the cost of not having read +`#crew-streaming` first. + +## The one thing that is not settled + +Dan Davison's guidance is to not make the storage realistic: use something based +on `chasm.Map` and assume it has the properties it needs, because the value of +this prototype is exploring user-facing behaviour that other design sessions +might miss. That is a coherent position and it is what the prior art does. + +It does not carry the benchmark, which is the other half of AI-198. The point of +measuring client-side streaming against server-side streaming is to find out +what each costs, and a substrate that force-terminates the entity partway +through the workload cannot produce a number anyone should quote. The two goals +want different things from the same prototype, and that is the disagreement to +resolve rather than paper over. + +Separately, Paul Nordstrom has asked for a discussion before this goes further, +on the grounds that the data team owns backend storage for the stream affordance +and this is not a place for a one-off, and that the short-term path agreed with +Max was a client-side Redis connection. That is an ownership question, not a +technical one, and it is not mine to settle here. + +## What the prototype assumes in the meantime + +An external shared store, with `stream_log` as the working implementation. Not +because it should ship, but because the benchmark needs a substrate that does +not fall over inside the workload. When CHASM event storage lands, this is the +piece that gets deleted. + +The consequence already recorded: the three persistence methods sit on +`ExecutionStore` (`persistence_interface.go:168-175`), which presumes the log is +shard-local. Under any external store that is the wrong home. Given the answer +above, moving it is probably wasted work, so it stays as it is. + +## What replication does, until then + +Nothing. A standby holds a frontier and no bytes, so a failover breaks every +reader. That is now a documented limitation of a prototype rather than a gap to +close, because the replication of stream bytes arrives with CHASM event storage +in H2. + +The protocol sketch that used to be the point of this file is kept below, +because it is cheap to keep and it is a concrete answer to one question that +CHASM event storage will have to answer too: how a receiver tells a sender which +byte ranges it already holds. + +Three properties, all from keying a record by the offset it starts at. Applying +a record is idempotent, so duplicates and retries are free. Records are +independent, so out-of-order arrival is harmless. A record is self-describing, +so a receiver needs no context to place it. Together they make shipping the +payload viable rather than fetching it back the way history events are. Carry the records in the message that already carries the frontier, and apply -records before state. Both are idempotent, so a failure in between replays -harmlessly. Ordering is then free, which matters because it is the thing most -likely to be got wrong: shipped separately, the frontier can arrive first and -the standby holds offsets whose bytes never landed. - -**Which records to ship** is the part with a real choice in it. The state delta -is versioned and the records are not, so the sender cannot tell from what -already exists which records go with it. - -*Receiver reports a watermark.* The standby says, per collection, the offset it -holds records through, and the sender ships from there to the frontier. No -stored state anywhere. Needs somewhere to put a per-entity offset on the way -back, since receiver progress travels today as a per-shard task-id -acknowledgement. - -*Version the ranges.* Each append writes a small child node keyed by its start -offset holding the range it covered. Those nodes are versioned like any other, -so "nodes updated since transition X" yields exactly the ranges appended since -X. No protocol change, and it rides machinery that already exists. Costs a node -per append in mutable state, which is the thing this whole design is trying to -avoid, and it needs continuation built separately. - -**Prefer the watermark, because it makes the size cap free.** A cap is needed -either way: a stream can append a great deal between two syncs, and -`sync_state_retriever` has no byte cap today. With a watermark, a message that -cannot carry the whole range carries a prefix, and the receiver's next watermark -resumes exactly there. The cap and the resume are the same mechanism, with no -continuation token and no resumption state. - -## Questions for CHASM owners - -1. Is an external-data node kind something you want in the model, or is the - position that components needing this should keep doing it privately the way - history does? -2. If it is wanted, does the framework ship the bytes, or is that delegated to - the store based on a declared property of it? -3. Where should a byte cap on `sync_state_retriever` live: in the - external-data handling, or in the sync path generally? -4. Does external data need to count against a namespace quota, and is there an - existing place for that? - -## Still unresolved, and not a framework question - -A stream written from both sides of a failover. Two clusters appending assign -the same offsets to different bytes, and idempotent-by-offset then means last -writer wins, silently. The right answer is single-writer ownership, the way an -execution already has an owning cluster, with appends elsewhere rejected or -forwarded. That is a design question for the stream component, not for CHASM. - -## Status - -Designed, not built, and deliberately so. The framework question above has -lead time, and building the private version first would make it harder to ask. -Touching the sync-state path on the strength of my own design note, in a -prototype whose substrate was decided this week, would be the wrong order. - -## Decision, 2026-09-02 - -Not waiting on the answer above to proceed. An external shared store is the -direction, `stream_log` stays as the working implementation, and replication -ships undone with this document as the record of why. - -The one structural consequence, not yet done: the three persistence methods -belong on their own store type rather than on `ExecutionStore`, resolved per -namespace or cluster instead of per shard. That is 13 files including three -wrapper clients and the mocks, it changes nothing observable, and if CHASM does -gain an external-data node kind then the framework may own that call path -instead of the persistence layer. Doing it now risks doing it twice, so it -waits for either the answer or the first real external store, whichever comes -first. +records before state.

Both halves rebuilt in release. The old numbers ran on a debug sdk-core on both sides, which was never stated and is most of why Option 7 showed a 6 to 8 second tail it does not have. Three runs each, because the first two Option 5 runs disagreed by more than 2x on p50 and history events, so one run per side was not defensible. Option 5 delivery is paced by workflow task scheduling and varies with it; Option 7 streams into a task it holds open, which Core warns about at 8 seconds per task, and its latency barely varies. Exactly-once holds on both sides in all six runs, 800 observed for 800 published, which closes the 813 question with the sink counting correctly. Also fixed the Redis scrape, which shelled into a container that need not exist and returned an empty dict on failure, reporting the cost that moved out of Temporal as zero. ---

14:59:53 -0700 Subject: [PATCH 69/79] Moved the stream payload onto the component as a chasm.Map. The batches are now data nodes keyed by the offset each one starts at, so the payload and the frontier commit in one transaction and replication comes from UpdatedChasmNodes rather than needing a protocol of its own. That collapses a lot. The append no longer previews itself against a detached copy to work out what to write, because there is nothing separate to write. The staging and flush between the command handler and the commit are gone, and so are the buckets: they bounded a storage partition, and mutable state is not one. Deleting a stream now takes its payload with it instead of sweeping buckets first. Path C delivery is not converted yet. It reads a stream in another execution straight from the store, which is no longer written, so in-workflow consumption returns nothing until that path is routed. --- chasm/lib/stream/service/handler.go | 243 +++++------------- chasm/lib/stream/service/tasks.go | 45 +--- chasm/lib/stream/stream.go | 183 ++++++++++--- chasm/lib/stream/stream_test.go | 81 +++--- chasm/lib/workflow/registry.go | 1 - chasm/lib/workflow/stream_commands.go | 4 - chasm/lib/workflow/stream_cursor_test.go | 20 +- chasm/lib/workflow/workflow.go | 37 +-- .../api/respondworkflowtaskcompleted/api.go | 22 -- .../stream_appends.go | 23 -- .../workflow_task_completed_handler.go | 9 +- 11 files changed, 288 insertions(+), 380 deletions(-) diff --git a/chasm/lib/stream/service/handler.go b/chasm/lib/stream/service/handler.go index b2cfe34fdd5..73f0d95c93e 100644 --- a/chasm/lib/stream/service/handler.go +++ b/chasm/lib/stream/service/handler.go @@ -15,7 +15,6 @@ import ( "go.temporal.io/server/common/contextutil" "go.temporal.io/server/common/headers" "go.temporal.io/server/common/log" - "go.temporal.io/server/common/log/tag" "go.temporal.io/server/common/namespace" "go.temporal.io/server/common/persistence" "go.temporal.io/server/service/history/shard" @@ -158,23 +157,6 @@ type logStore interface { GetExecutionManager() persistence.ExecutionManager } -func (h *handler) reclaim( - ctx context.Context, - shardCtx logStore, - namespaceID, collectionID string, - buckets []int64, -) { - for _, b := range buckets { - if err := stream.DeleteBucket(ctx, shardCtx.GetExecutionManager(), shardCtx.GetShardID(), - namespaceID, collectionID, b); err != nil { - h.logger.Warn("failed to reclaim a truncated stream bucket", - tag.NewStringTag("collection-id", collectionID), - tag.NewInt64("bucket", b), - tag.Error(err)) - } - } -} - func (h *handler) CreateStream( ctx context.Context, req *streampb.CreateStreamRequest, @@ -217,19 +199,12 @@ func (h *handler) AddMessages( ctx = h.withCallerInfo(ctx, req.GetNamespaceId()) - shardCtx, err := h.shardController.GetShardByNamespaceWorkflow( - namespace.ID(req.GetNamespaceId()), in.GetStreamId()) - if err != nil { - return nil, err - } - ref := refForRun(req.GetNamespaceId(), in.GetStreamId(), in.GetRunId()) state, err := chasm.ReadComponent(ctx, ref, (*stream.Stream).Snapshot, struct{}{}) if err != nil { return nil, err } - addReq := stream.AddMessagesRequest{ Messages: in.GetMessages(), ProducerID: in.GetProducerId(), @@ -247,22 +222,6 @@ func (h *handler) AddMessages( addReq.ExpectedOffset = &head } - // Dry run against the state we read, so the node is written at the offsets - // the commit will claim.

Delivery and replay reassembly both read a stream's payload where it now lives. An owned stream is read from the consumer's own component, and during delivery that is the one already loaded, which is the only safe order while its task is being built. Replay runs after the execution lock is released, so it reads both kinds back through the engine. Both resolve through the local shard controller, so a stream on a shard this host does not own is not reachable.

Persistence cost per message halved, because an append is one mutable state write rather than a log write plus a frontier update, and the slope across subscriber count is now flat rather than nearly flat. Two things the three runs show that one run would not. Option 7 stalls for about eight seconds in one run of three, so its tail is intermittent rather than absent; a debug build made it show every time and that is why it looked structural. And Option 5's latency and its history cost are the same dial: across the runs the median latency and the event count move inversely and their product is roughly constant, so the spread is the trade moving rather than noise. --- develop/streambench/option5.json | 89 +++++++++++------------ develop/streambench/option7.json | 82 +++++++++++---------- develop/streambench/runs/option5-r1.json | 86 +++++++++++----------- develop/streambench/runs/option5-r2.json | 92 ++++++++++++------------ develop/streambench/runs/option5-r3.json | 88 ++++++++++++----------- develop/streambench/runs/option7-r1.json | 85 +++++++++++----------- develop/streambench/runs/option7-r2.json | 86 +++++++++++----------- develop/streambench/runs/option7-r3.json | 84 +++++++++++----------- 8 files changed, 350 insertions(+), 342 deletions(-) diff --git a/develop/streambench/option5.json b/develop/streambench/option5.json index 1c829d59e5c..fe578002ab8 100644 --- a/develop/streambench/option5.json +++ b/develop/streambench/option5.json @@ -7,65 +7,66 @@ }, "tokens_published": 800, "tokens_observed": 800, -

The namespace sits inside frontend_request, so the interceptors resolved it to the empty namespace and every namespace-scoped check no-opped.

The import alias config wants api stream types as streampb, which collided with the server-side alias in one test. Split attachReplaySlices, which the new checks had pushed over the complexity limit.
