Dictionary-encode primitive Arrow exports without arrow_cast by joseph-isaacs · Pull Request #10802 · vortex-data/vortex

joseph-isaacs · 2026-10-26T14:21:03Z

Summary

Split out of #10761.

Exporting a primitive array as an Arrow dictionary went through arrow_cast. That cast hashes every value with SipHash and builds an ArrowError per value. On PolarSignals this export was about 90% of scan CPU, for both V1 and V2. Most of the PolarSignals gains in #10761 (hot geomean 0.564x) came from here.

Changes

primitive_to_dict encodes integer, float (by bits), date and timestamp arrays natively. It picks the first of these that applies:

A dense lookup table, when the keys span fewer than 65,536 values.
The values themselves with sequential codes, when a 1,024-value sample is nearly all distinct. Arrow dictionaries may contain duplicates, so this is valid.
An FxHash map, sized from the sample.

The full min/max scan only runs 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.

New tests cover:

nulls;
float bit-equality (0.0 and -0.0, NaN);
the all-distinct path;
a full UInt8 code space;
the overflow fallback, which still errors.

Checks run: cargo clippy -p vortex-arrow --all-targets --all-features -- -D warnings, cargo +nightly-2026-09-10 fmt -p vortex-arrow, and cargo test -p vortex-arrow --lib dictionary.

The License Check and Audit Check (advisories) failure is not from this PR. cargo deny reports new zstd 0.13.3 advisories, including RUSTSEC-2026-0391; the fix is zstd >= 0.14.3. That version comes from the workspace zstd = "0.13.3" pin in Cargo.toml and from arrow-avro, neither of which this diff touches. The job is continue-on-error, so it doesn't block merging. There's no fix PR yet: it needs a workspace zstd bump, or an ignore entry in deny.toml while arrow-avro still pins 0.13. The same failure applies to #10800, #10801 and #10803.

Merging this PR will regress 2 benchmarks

4 warnings, 1 note

⚠️ Walltime results may be unreliable

Some benchmarks used the Walltime instrument outside CodSpeed Macro Runners, which can make the results inconsistent.

See affected benchmarks

⚠️ Unable to measure the execution of 2 benchmarks

These benchmarks measured no execution time, so their results are not comparable and count as unchanged. This usually happens when the compiler removes the code under test.

Prevent compiler optimizations

⚠️ 24 benchmarks are dominated by system calls

System calls cannot be simulated consistently and are left out of the measure. The reported value understates the real cost. Switch to the Walltime instrument to measure them.

⚠️ Base and head ran on different runner types

Some benchmarks with significant performance changes were compared across different runner types, so the changes might not come from the code. Run base and head on the same runner type, or use CodSpeed Macro Runners for more stable results.

Neither CodSpeed regression on a6867e9 comes from this PR:

chunked_dict_primitive_canonical_into[f64, (1000, 1000, 10)] (-26.6%): this vortex-array benchmark doesn't run the Arrow export changed here. The same -26.6% against the same develop baseline (bbb562a) shows up on Size filtered V2 scan splits by projected bytes and threads #10800 and Emit projection pieces as separate batches #10801, which change other crates, so the cause is that baseline.
bitpack_blocked_compress_avx2 (-11%): this is a walltime benchmark of FastLanes compression, which this PR doesn't touch. It shows the same -11% on fix: bit-packed arrays cast match more often #10803, which changes only a cast kernel. CodSpeed also warns that walltime results outside its dedicated runners are unreliable, and that base and head ran on different runner types.

Commits: PR a6867e9c vs base 46429f5c
Verdict: No clear signal (low confidence)
Attributed Vortex impact: +4.9%
Engines: DataFusion No clear signal (+9.7%, low confidence) · DuckDB No clear signal (+0.3%, low confidence)
Vortex (geomean): hot 1.050x ➖ · cold 1.023x ➖

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.

Commits: PR a6867e9c vs base 59d1b4a5
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -0.7%
Engines: DataFusion No clear signal (-4.9%, environment too noisy confidence) · DuckDB No clear signal (+3.6%, environment too noisy confidence)
Vortex (geomean): hot 1.064x ➖ · cold 1.112x ➖
Parquet (geomean): hot 1.072x ➖ · cold 1.090x ➖
Shifts: Parquet (control) +7.2% · Median polish +7.3%

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: +0.2%
Engines: DataFusion No clear signal (-0.9%, low confidence) · DuckDB No clear signal (+1.3%, low confidence)
Vortex (geomean): hot 0.999x ➖ · cold 0.990x ➖
Parquet (geomean): hot 0.997x ➖ · cold 0.996x ➖
Shifts: Parquet (control) -0.3% · Median polish -0.3%

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.
