Bound V2 shared reads and partition DuckDB scan work by joseph-isaacs · Pull Request #10857 · vortex-data/vortex

joseph-isaacs · 2026-10-27T12:52:55Z

Summary

V2 work ranges can overlap stored segments, duplicating reads and retaining buffers after their consumers finish. Drivers now share reads within one file execution and release them when owned row claims prove no unfinished work can read them again. DuckDB assigns work across its configured threads; DataFusion preserves independently scheduled scan chunks.

Changes

Move pending/completed read sharing to vortex-scan::planning::driver::FileReads. Queued planners, filtering, pruning, projection, and morsels transfer or split RowClaim ownership. Completed later parts can release their reads while an earlier part remains stalled.
Derive conservative consumer ranges from the stored layout. Dictionary values and auxiliary children inherit their enclosing root-row region. Missing lifetime information retains a read until file execution ends.
Partition DuckDB work on a 65,536-row grid, with at most 1,048,576 rows per assignment. For one projected string/binary column, preserve dictionary regions when that supplies enough assignments; coalesce only regions below 8,192 rows. Inspect the projected row-domain metadata without opening dictionary values or unrelated fields, and fall back to the static grid when metadata is unavailable.
Let DataFusion explicitly request independent chunk planners. The shared planner had changed Spawn into ordinary child planning, moving chunk execution onto the root scan task. Restoring independent chunks recovers parallel compute and read scheduling. DuckDB retains ordinary child planners inside its own work assignments.
Share dictionary inputs between filtering and projection, retain encoded predicate inputs and materialized boolean results, and release decoded predicate inputs. Preserve structural expression caching, sparse projection, unused-field pruning, and short-edge chunk merging.
Share concurrent DuckDB dictionary conversions through one initialization cell per dictionary. Gather sparse string/binary selections before export. Allow larger DuckDB projection batches while preserving DataFusion's output limit and byte bounds for identity projections.
Preserve develop's stricter DuckDB filter-argument checks. The regression case now returns the expected 40,000 rows in both scan modes instead of dropping the V1 filter and returning 200,000.

Planner interfaces remain experimental; constructors and pruning continuations transfer row claims.

Performance

ClickBench CI and controlled diagnostics tested aa2cf422. Final head df3c42df has identical Rust sources; its only subsequent change removes temporary diagnostic workflows. The controls were built from develop c56ee880 and the preceding PR's Rust sources at d704b47a, with matching compiler flags.

DataFusion Q38

Both controls and the candidate use V2 scanning and the same input files on one 96-core Graviton runner. Each version was warmed before two ABBA comparisons, with 30 iterations per trial and the first iteration excluded: 58 retained samples per version in each comparison.

Controlled comparison	Before (ms)	Candidate (ms)	Time change
Pre-fix PR vs candidate	18.879	12.759	−32.4%
Develop V2 vs candidate	12.656	12.781	+1.0%

The native CPU profiles corroborate the scheduling change: before, 22.72% of sampled cycles run through the root scan's spawn_cpu path; after, 23.30% run through independent chunk_stream tasks and only 0.89% through that root path. The scan metrics report the same output rows and segment-cache misses, with individual I/O requests falling from 11 to 2. This is primarily an elapsed-time improvement from scheduling, not less total CPU work.

The full 43-query report reduces DataFusion's attributed warm regression from +10.4% in the preceding rerun to +2.7%, with low confidence. Q20, Q21, Q23, Q26, Q28, and Q38 are now within 3.6% of the cached develop warm reference. This does not establish parity for every query: DataFusion Q24 remains +14.8%, and the combined Vortex cold geometric mean remains +13.4% in the report.

DuckDB Q28

Measurement	Before (ms)	After (ms)	Time change
CI: earlier PR `52b50e21` vs current	648.964	499.136	−23.1%
Local warmed V2 ABBA: `52b50e21` vs dictionary-aligned scheduler	1261.474	1128.896	−10.5%

The local comparison used 32 DuckDB/Tokio threads, 100 partitioned ClickBench files, and fresh connections. Both binaries were warmed; two eight-iteration trials per version retained 14 warm samples. Seven guard queries were checked, no benchmark/build workloads overlapped, and all 200 input-file size/mtime records remained unchanged. Existing benchmark processes and Cargo caches were preserved.

Current CI Q28 is 2.4% below the cached develop reference of 511.325 ms. Develop's DuckDB reference uses V1, so that comparison is not V2 versus V2. Earlier runs of the dictionary-aligned scheduler measured 500.956, 501.121, and 502.467 ms. Other DuckDB regressions remain, including Q20 (+14.3%) and Q38 (+24.8%) versus the cached reference.

Memory and retention

Restoring DataFusion Q38 parallelism increases median peak RSS across the paired 30-iteration trials from 1.95 to 2.32 GiB (+18.8%); develop measured 2.29 GiB. More simultaneous work is the tradeoff for the lower elapsed time.

The earlier local DuckDB Q28 comparison reduced peak RSS from 7.50–7.55 GiB to 4.95–5.84 GiB. These measurements compare V2 implementations and do not establish whole-process memory parity with V1. Decoded arrays and output buffers can retain memory independently of read-cache eviction.

The controlled 32-part retention test holds the first part stalled while later parts finish. Flat reads retained fall from 32 segments / 128 KiB under the former watermark policy to 2 / 8 KiB; dictionary reads fall from 33 / 144 KiB to 3 / 24 KiB. Each segment is fetched once, and the cache empties after the final claim drops.

Validation

Final-head regular CI passed, including formatting, Clippy, Linux/Windows and CPU-feature Rust tests, SQL logic tests, and integration checks. Instrumented Rust, musl, and CUDA workflows also passed.
Full ClickBench and controlled Q38 diagnostics passed. The diagnostics artifact includes raw timings, metrics, explain plans, binary hashes/build IDs, and native profiles.
Regression coverage checks bounded selections for both ordinary and independent chunk planners. Existing retention and dictionary-region tests continue to run in CI.
Local Q28 timings, guards, and profiles are recorded above. The new DataFusion comparison ran on isolated CI runners while the other local benchmark continued. Local pinned formatting could not run because its toolchain installation ran out of disk space; final-head CI formatting passed. No existing caches were removed.
Patch whitespace checks passed; temporary CI instrumentation is removed from the final diff.

How to read Verdict and Engines

Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

How to read Verdict and Engines

Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

Benchmarks: TPC-H SF=10 on NVME 📖

Commits: PR d704b47a vs base c56ee880
Verdict: No clear signal (low confidence)
Attributed Vortex impact: -2.2%
Engines: DataFusion No clear signal (+0.0%, low confidence) · DuckDB No clear signal (-4.4%, low confidence)
Vortex (geomean): hot 0.977x ➖ · cold 0.974x ➖
Parquet (geomean): hot 0.999x ➖ · cold 0.969x ➖
Shifts: Parquet (control) -0.1% · Median polish -0.1%

How to read Verdict and Engines

Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

How to read Verdict and Engines

Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

How to read Verdict and Engines

Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

How to read Verdict and Engines

Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

We'd need to tackle ClickBench regression before merging

…unks Fall back to the driver's normal partitioning when a lazy chunk's metadata cannot be initialized. Selection and pruning may avoid executing that chunk. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Only coalesce tiny dictionary regions below 8192 rows, allowing workers to balance dictionary expressions without cutting their cached value domains. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Run the PR and its develop base on the same ClickBench runner, with warmed ABBA timings, scan metrics, and native CPU profiles. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Avoid mixing current develop workflow actions with an older PR checkout during the controlled comparison. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

The shared chunk planner had stopped emitting independent work, moving DataFusion scans onto the root task's step-by-step execution. Allow DataFusion to opt into independent chunks while DuckDB keeps its own work queue policy. Cover the independent planner's bounded selection scope. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

The active benchmark run retains its pinned diagnostic workflow. Keep the PR change limited to DataFusion chunk scheduling and its regression coverage. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>
