feat(aggregate): add ExtensionStoragePushdown to push an aggregate into an extension type's storage by joseph-isaacs · Pull Request #10566 · vortex-data/vortex

joseph-isaacs · 2026-10-16T15:57:19Z

Summary

Aggregates that support an extension dtype currently do so by hand: each one matches Canonical::Extension and recurses on storage_array() (min_max, is_constant, is_sorted, uncompressed_size_in_bytes, the zoned bloom filter). Aggregates that don't, such as IsSorted, reject extension dtypes outright, even where running them on the storage is correct (e.g. timestamps, which compare like their i64 storage).

This adds an opt-in pushdown: declaring that one aggregate may run on one extension type's storage is a single registration, with no per-aggregate code:

session.aggregate_fns().register(ExtensionStoragePushdown::new(IsSorted, Timestamp));

Changes

New ExtensionStoragePushdown<A: AggregateFnVTable, E: ExtVTable> in vortex-array/src/aggregate_fn/storage_pushdown.rs, an AggregateFnVTable of its own:
- id <A>[<E>] (e.g. vortex.is_sorted[vortex.timestamp]), built once in new; it never replaces A. Options serialize and deserialize through A, so a registered pair round-trips by id.
- accepts only extension dtypes of type E; any other input makes return_dtype/partial_dtype return None.
- the partial is A::Partial, and every vtable call forwards to A with the storage dtype borrowed from the extension dtype, so partial handling allocates nothing (perf(aggregate): hold the storage partial directly in ExtensionAggregate #10612).
- unwraps each batch to its storage array and accumulates it through a per-batch Accumulator<A>, so kernels and cached stats registered for A on storage encodings still fire. Constant extension batches become constant storage arrays.
- partials and results are those of A over the storage dtype, with no lifting back to the extension.
The doc comment says a registration is an unchecked claim, and is only correct when two things hold:
- E's domain supports the aggregation.
- The storage computes it soundly. Each operation the aggregate uses must give the same answer on the storage: comparison, equality, addition, NaN detection.
It uses Date/Time/Timestamp as the example (comparison yes, sum no), and a doctest registers and runs ExtensionStoragePushdown<IsSorted, Timestamp>.
The existing hand-written storage delegations are left unchanged: they handle every extension type rather than one specific E.

Tests:

pushes_down_into_storage registers ExtensionStoragePushdown<MinMax, Timestamp>, finds it by id, and checks that the result matches MinMax over the storage.
combines_flushed_partials checks that merging two flushed partials matches accumulating both batches.
rejects_other_extension_types checks that a Date input is rejected.
A doctest shows registering and running a pair.

API Changes

Adds the public vortex_array::aggregate_fn::ExtensionStoragePushdown. Nothing existing changes.

⚠️

Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

⚠️

1 benchmark measured no execution time

Nothing ran under measurement, usually because the compiler removed the code under test. This result is not comparable, so it counts as unchanged.

CodSpeed Performance Analysis is red on 3db29a5, but I don't think either regression is this PR's:

chunked_opt_bool_canonical_into[(1000, 10)] (-15%) builds canonical bool arrays from chunks.
test_scan_filter[int] (-11%) is a Python scan with a filter on an int column.

This PR only adds ExtensionAggregate (vortex-array/src/aggregate_fn/extension.rs) and its module line. Nothing existing calls it or registers it, so neither benchmark can reach the new code. The previous CodSpeed run on 241723d also flagged 4 regressions, and none of them are among these 2. Most of the flagged benchmarks there were Python scans with flame graphs unavailable. CodSpeed's own report warns about walltime runs on hosted runners and about comparisons across different runtime environments.

No fix is needed in this PR. The regressions can be acknowledged on CodSpeed.

The adapter is an opt-in pushdown of one aggregate into one extension type's storage, not an aggregate over any extension type, so name it for that and move it to aggregate_fn/storage_pushdown.rs. Expand its docs: registering a pair is an unchecked claim about the extension type; a pushdown is correct only when every operation the aggregate uses (comparison, equality, addition, NaN detection) derives from the same operation on the storage; Timestamp supports it for comparison but not addition. Switch the tests and examples from Sum to MinMax, which is correct for Timestamp.
