feat(compressor): measure inputs and blocks by the bytes their rows reference by joseph-isaacs · Pull Request #10445 · vortex-data/vortex

joseph-isaacs · 2026-10-12T11:24:31Z

Summary

Second of three stacked PRs, on top of vortex-data/vortex#10439. Uses the exact uncompressed size where nbytes() overstated view arrays that share a decompressed Parquet page.

Changes

CascadingCompressor measures the input, and each leaf a scheme competes against, by the bytes its rows reference. A dictionary of distinct strings no longer looks like a 20x win against a 2 MiB shared page. Sampling scores slices the same way.
The repartition writer coalesces blocks by the exact size, so 27 KiB string blocks reach the 1 MiB block_size_minimum instead of each being emitted alone. The Python dataset test's fragment count drops from 26 to 16 as the string column's blocks now line up with the numeric columns'.
The compressing layout caches the exact size on each chunk before compression so the compressor reads it instead of recomputing it. The statistic is serialized with the others, so a written file grows by a few bytes per leaf; the stock ticker file size test moves by 24 bytes.
A dtype the aggregate cannot measure, such as variant, is sized by the bytes it holds.

…ure blocks exactly Arrow's Parquet reader points each batch's string views into the whole decompressed page, and VarBinView::slice keeps every buffer, so the nbytes() of an 8,192-row block of TPC-H l_comment was about 1 MiB for 27 KiB of strings. The repartition writer measured blocks with nbytes(), so every block already exceeded the 1 MiB minimum and never coalesced. Rather than trimming buffers on import, which costs a pass over every imported view array, keep the import zero-copy and let callers that size blocks ask for a precise measurement: - `UncompressedSizeInBytes` takes `UncompressedSizeOpts { precision }`. `Inexact` (the default) keeps today's behaviour and counts every held buffer. `Exact` counts only the bytes the valid rows reference: a VarBinView walks its views, a ListView rebuilds to its referenced elements, nested types forward the precision to their children, and fixed-width types are the same either way. - The `Stat::UncompressedSizeInBytes` slot is the exact size. Only the exact aggregate reads and writes it as `Precision::Exact`; an inexact measurement is cached as `Precision::Inexact`, an upper bound that inexact queries reuse and exact queries ignore. `compute_stat`, and so file statistics, now measure exactly. - The repartition coalescer measures each block exactly, so view blocks sharing a large buffer coalesce up to `block_size_minimum`. Adds a regression test streaming ten 8,192-row view blocks that share a 2 MiB buffer and asserting they coalesce three to a block.

…tes from uncompressed output The writer caches the exact uncompressed size on every chunk before compression. The compressor now reads that size, computing it without recording anything where it is absent, as the baseline a scheme has to beat, for the full array and for the sampled slices whose views still point at the full array's buffers. Dead bytes in a view array's buffers no longer make a dictionary of distinct strings look like a 20x win. Compaction moves from before scheme selection to after it. A scheme that changes the encoding rebuilds the data it keeps, so its dead bytes are gone for free. An array that keeps its canonical encoding, because no scheme matched, won, or beat the exact size, is compacted when it holds more than its rows reference: buffers used end to end are kept, contiguous ranges are sliced without copying, and the rest rewritten. The previous up-front compaction skipped arrays holding at most 128 bytes per row or with over half their bytes referenced, which let an Arrow page shared by 8,192-row blocks pass through whole. `uncompressed_size_in_bytes_uncached` measures columnar arrays without caching a statistic on them or their children, since an uncompressed leaf is serialized with its statistics and a size the compressor measured for itself would grow the file.

…fragments The uncompressed size aggregate does not apply to variant arrays, so the coalescer, the compressing layout and the compressor fell over on the first variant chunk. Each now checks the dtype first and sizes an unsupported array by the bytes it holds, as before. The Python dataset test counted 26 fragments, which were the row splits left by string blocks that never coalesced. Measured exactly, the string column's blocks line up with the numeric columns' and the file has 16.

…e flag The exact size of a list view's elements is found by scanning offsets and sizes: lists that tile one contiguous run are measured as a slice of it, fixed-width elements are sized by count, and only overlapping or gapped lists of variable-width elements are rebuilt. The accumulator already caches an exact result through the stat slot, so the cache flag and the uncached variant go. Precision is documented as approximate versus actual bytes used.

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 9c23a32b vs base 787fac76
Verdict: No clear signal (low confidence)
Attributed Vortex impact: +0.1%
Engines: DataFusion No clear signal (+0.3%, low confidence) · DuckDB No clear signal (-0.1%, low confidence)
Vortex (geomean): hot 1.000x ➖ · cold 0.975x ➖

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: FineWeb S3 📖

Commits: PR 9c23a32b vs base 787fac76
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +14.9%
Engines: DataFusion No clear signal (+24.4%, environment too noisy confidence) · DuckDB No clear signal (+6.0%, environment too noisy confidence)
Vortex (geomean): hot 1.020x ➖ · cold 1.003x ➖
Parquet (geomean): hot 0.888x ➖ · cold 0.907x ➖
Shifts: Parquet (control) -11.2% · Median polish -5.7%

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-DS SF=1 on NVME 📖

Commits: PR 9c23a32b vs base 787fac76
Verdict: No clear signal (low confidence)
Attributed Vortex impact: -0.1%
Engines: DataFusion No clear signal (-0.4%, low confidence) · DuckDB No clear signal (+0.3%, environment too noisy confidence)
Vortex (geomean): hot 0.998x ➖ · cold 1.010x ➖
Parquet (geomean): hot 0.999x ➖ · cold 1.001x ➖
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.

Benchmarks: TPC-H SF=10 on NVME 📖

Commits: PR 9c23a32b vs base 787fac76
Verdict: No clear signal (low confidence)
Attributed Vortex impact: -0.3%
Engines: DataFusion No clear signal (-0.3%, low confidence) · DuckDB No clear signal (-0.4%, low confidence)
Vortex (geomean): hot 0.992x ➖ · cold 0.953x ➖
Parquet (geomean): hot 0.996x ➖ · cold 0.977x ➖
Shifts: Parquet (control) -0.4% · Median polish -0.4%

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.

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 9c23a32b vs base 85e7acfa
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -0.7%
Engines: DataFusion No clear signal (+10.3%, environment too noisy confidence) · DuckDB No clear signal (-10.5%, environment too noisy confidence)
Vortex (geomean): hot 1.095x ➖ · cold 1.043x ➖

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: Random Access (S3) 📖

Commits: PR 9c23a32b vs base 85e7acfa
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -6.4%
Engines: random-access No clear signal (-6.4%, environment too noisy confidence)
Vortex (geomean): hot 0.964x ➖
Parquet (geomean): hot 1.030x ➖
Shifts: Parquet (control) +3.0% · Median polish +2.8%

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.
