Speed up PolarSignals scans: spread filtered V2 splits and export primitive dictionaries natively by joseph-isaacs · Pull Request #10761 · vortex-data/vortex

joseph-isaacs · 2026-10-23T22:34:52Z

Summary

On PolarSignals with DataFusion, scan V2 from #10706 was 1.79x slower than V1 (geomean). This PR fixes that. It also speeds up both V1 and V2 by making the Arrow dictionary export cheaper; that export was ~90% of scan CPU on these queries for both scans. V2 and V1 now perform about the same on PolarSignals.

CI action/bench-sql on a47ec03 against develop (CI's PolarSignals job runs V1):

Suite	Vortex hot geomean	Notes
PolarSignals	0.564x	q00 −80%, q01 −71%, q02 −74%, q03 −65%, q08 −38%; no regressions
TPC-H SF1 / SF10 / S3	1.004x / 0.996x / 0.988x	no clear signal
TPC-DS SF1	0.999x	no clear signal
ClickBench, FineWeb	0.992x, 0.992x	no clear signal

Local runs at SF1 on 4 cores, median of 3 rounds × 5 iterations, sides alternated:

PolarSignals	V1 before	V2 before	V1 after	V2 after
q01	1067 ms	2927 ms	107 ms	108 ms
total	4.44 s	10.62 s	1.40 s	1.39 s

Changes

Filtered V2 splits (vortex-layout). Filtered scans used fixed ~1M-row chunks. A DataFusion byte-range partition of a ~1M-row file was therefore one chunk, so when the selected rows sat in one partition, a single thread did all the work. Chunks are now sized two ways:
- by the serialized bytes the projection reads per row, cached per projection in ScanCache;
- by the partition's rows per thread.
Cheap projections over large ranges keep the 1M-row chunks.
No re-concatenation (vortex-layout). ProjectionMorsel emitted its pieces as one ChunkedArray, which the Arrow export then concatenated, re-merging nested dictionaries. Pieces are now separate batches; only pieces under 4,096 rows are grouped.
Primitive dictionary export (vortex-arrow). This replaces arrow_cast, which hashed each value with SipHash and built an ArrowError per value. The export now uses, in order of preference:
- a dense table for keys spanning fewer than 65,536 values;
- the values themselves with sequential codes, when a sample shows nearly every value is distinct (Arrow dictionaries may contain duplicates);
- an FxHash map sized from the sample.
The full min/max scan runs only when the sample's range could fit the dense table. Nulls stay in the codes. Other types, and codes that would overflow, fall back to arrow_cast.
Bit-packed arrays exported as dictionaries (vortex-arrow, vortex-fastlanes). A bit-packed array without patches holds only values in 0..2^bit_width, so the unpacked values serve directly as codes into that range. This applies up to 16-bit widths. BitPacked's CastKernel now also handles narrowing integer casts when there are no patches and the target type holds every value the bit width allows.

Tests cover nulls, float bit-equality, a full UInt8 code space, the overflow fallback, the all-distinct path, bit-packed export, and narrowing bit-packed casts.

The CodSpeed micro-benchmarks it flags don't run the code this PR changes; see the comment below.

…tion pieces Filtered V2 scans used fixed 1,048,576-row chunks. A DataFusion byte-range partition of a ~1M-row file then became a single chunk, so when the surviving rows sat in one partition (PolarSignals time ranges) one thread did all the work. Size filtered chunks by the serialized bytes the projection reads per row and by the partition's rows per thread, keeping 1M-row chunks for cheap projections over large ranges. ProjectionMorsel also wrapped its pieces in a ChunkedArray, which the Arrow export concatenated, re-merging nested dictionaries.

Exporting a non-dictionary Vortex array to an Arrow dictionary type went through arrow_cast, which hashes each primitive value with SipHash and builds an ArrowError per value. PolarSignals requests its nested `locations` fields as dictionaries, so this was ~90% of scan CPU for both V1 and V2. Encode primitive values directly, hashing their bits with FxHash and keeping nulls in the codes, and fall back to arrow_cast for other types or when the codes overflow. PolarSignals SF1 on DataFusion (V2): q00-q03 ~3.6x faster, total 4.28s -> 1.90s.

…ictionaries Hash-map growth and hashing still dominated exporting PolarSignals' nested dictionary fields. Keys spanning under 65,536 values (line numbers) are now looked up in a dense table. When a sample of the values is nearly all distinct (addresses), the values become the dictionary with sequential codes, reusing their buffer, since Arrow dictionaries may hold duplicates. Other inputs hash into a map sized from the sample. PolarSignals SF1 on DataFusion (V2): q00-q03 another 22-31% faster.

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.

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.

Verdict: No clear signal (low confidence)
Attributed Vortex impact: -0.4%

Vortex (geomean): hot 0.992x ➖ · cold 0.957x ➖

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.

Commits: PR a47ec03e vs base 91b38f41
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +3.7%
Engines: DataFusion No clear signal (-0.2%, environment too noisy confidence) · DuckDB No clear signal (+7.7%, environment too noisy confidence)
Vortex (geomean): hot 0.988x ➖ · cold 0.982x ➖
Parquet (geomean): hot 0.953x ➖ · cold 0.982x ➖
Shifts: Parquet (control) -4.7% · Median polish -0.9%

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.

A bit-packed array without patches only holds values in 0..2^bit_width, so its unpacked values are already codes into that range. Exporting it to an Arrow dictionary now unpacks straight into the codes type and uses 0..2^bit_width as the values, instead of decoding to the values type and dictionary-encoding the result. Applies up to 16-bit widths when the dictionary is no larger than the array. To unpack into narrower codes, BitPacked's cast kernel now also handles narrowing integer casts when the array has no patches and the target holds every value the bit width allows, skipping the generic bounds check. PolarSignals SF1 on DataFusion (V2): q00-q03 another ~2x faster.

…ange The primitive dictionary export scanned every key for its range before choosing an encoding, even for high-cardinality columns such as addresses that can never use the dense table. Sample first, and scan the full range only when the sampled keys fit the dense table.

CodSpeed Performance Analysis fails on a47ec03, but I don't think any of the flagged benchmarks run code this PR changes. The PR touches only vortex-arrow dictionary export, the BitPacked CastKernel and the vortex-layout scan v2 code:

filter_neon[8/64/80], threshold_neon[80] (encodings/fastlanes/benches/bitpacking_{filter,take}.rs). These time filter and take on BitPacked and never call cast, so the narrowing-cast change isn't on their path. They are walltime runs on a non-Macro runner, and CodSpeed notes that base and head ran on different runner types.
chunked_dict_primitive_canonical_into[f64] (vortex-array) and words_gather_dispatch_avx512 (vortex-buffer). This PR changes neither crate. Both were flagged before as well, when the branch was behind develop.
test_repeated_scan_scalar_at[int_float] (Python scalar_at). That path doesn't use dictionary export or the scan v2 filter path. Its sibling [int] case improved by 28% in the same run.

There's no fix to port for these. I'll re-check them on the next push.
