Add BlockedFoR: a frame of reference per 1024 values by joseph-isaacs · Pull Request #9609 · vortex-data/vortex

joseph-isaacs · 2026-08-25T13:18:32Z

Summary

FoR subtracts one minimum from a whole array, so the single bit width BitPacking then picks is driven by the spread of the entire array. Data that stays tightly clustered locally but drifts over the array — sorted keys, timestamps, counters, FSST/list offset vectors — pays for that global spread on every value.

BlockedFoR stores one reference per 1024-value block (the FastLanes chunk size, so a block lines up exactly with a bit-packing chunk). The residual bit width is then set by the widest block rather than by the array. The references live in a child array, which the cascading compressor compresses in turn, so the overhead is 8 bytes per 1024 values before that child is itself compressed.

This PR is additive and opt-in. ALL_SCHEMES is unchanged from develop, no golden snapshot changes, and no default write path can select the new encoding. Nothing here alters compressed output or query performance as merged; it lands the encoding so it can be evaluated and, if it earns its place, promoted later.

Changes

encodings/fastlanes/src/blocked_for/ — the new fastlanes.blockedfor encoding.

BlockedFoRData::encode splits into 1024-value blocks and subtracts each block's minimum. Nulls encode as a zero residual, exactly as FoR does, so they decode back to their block's reference instead of wrapping out of the primitive range.
A < 1024 block offset in metadata makes slicing exact without re-encoding, mirroring how BitPacked handles the same problem: a slice keeps the blocks it overlaps and records where inside the first one it starts.
block_summary is a single linear pass returning the widest per-block range and whether every block minimum is already zero. The scheme uses it to decide.
Serde, statistics, validity, canonicalization and slicing follow the existing FoR vtable layout. New golden metadata file at encodings/fastlanes/goldenfiles/blockedfor.metadata.

vortex-btrblocks/src/schemes/integer/blocked_for.rs — BlockedFoRScheme, deliberately not in ALL_SCHEMES.

An encoding must belong to an enabled edition before the writer will serialize it, and fastlanes.blockedfor is a preview member. A feature flag cannot express "this session's editions permit this encoding" — vortex-file/unstable_encodings enables vortex-btrblocks/unstable_encodings without enabling vortex/unstable_encodings, which is what gates the preview edition — so the scheme is opted into explicitly instead:

BtrBlocksCompressorBuilder::default()
    .with_new_scheme(&BlockedFoRScheme)
    .build()

That keeps the invariant that matters: no default write path can produce an array the file writer cannot serialize. Paths that build a WriteStrategyBuilder directly (vortex-ffi, vortex-python, vortex-tui, the CUDA writers) leave the encoding policy unset, so nothing would filter a scheme that slipped into the default set. Pinned by default_schemes_exclude_blocked_for.

The scheme produces only BlockedFoR and returns Skip wherever a single global reference is the better shape — single-block arrays, block-constant arrays, and data whose blocks span the same range as the array. FoRScheme competes for those on its own estimate. Declaring one produced encoding rather than two also keeps retain_allowed_encodings correct: a policy permitting fastlanes.for but not fastlanes.blockedfor drops only the blocked scheme and keeps frame of reference, pinned by retain_allowed_encodings_keeps_global_for_without_blocked.

vortex/src/editions/preview/v2026_08.rs — fastlanes.blockedfor joins the new PREVIEW_2026_08_0 edition, following how fastlanes.delta landed, and DEFAULT_PREVIEW_EDITION advances to it.

What this buys, measured

Compressed array bytes at 131072-row chunks, with vortex-btrblocks's plain scheme set (no pco, zstd, or unstable_encodings) plus BlockedFoRScheme:

dataset	overall	on the columns that changed
TPC-H lineitem sf=0.1	4.17%	`l_orderkey` 18.3%, `l_comment` 6.8%
ClickBench hits (1M rows)	0.22%	2.53% over 44 columns
NYC taxi 2023-11	0.18%	0.99% over 4 columns

Chunk size dominates — the bigger the compression unit, the more a single global reference costs. On lineitem: 2.56% at 8192 rows, 4.89% at 65536, 5.77% at 1M. Compression time was a wash (−5.7% on lineitem, −7.1% on ClickBench, i.e. noise-level).

With unstable_encodings on, Delta wins these shapes. After #9602 priced its bases and tail padding correctly, Delta beats the blocked scheme wherever both apply — every unstable__* golden case is unchanged by adding BlockedFoRScheme. So the numbers above describe the default scheme set; that is the honest scope of the win today.

Because the scheme is out of the default set, the standard benchmark suites cannot exercise it: nothing opts it in, so a bench-* run on this PR measures a build that compresses byte-identically to develop. The numbers above come from a purpose-built harness that adds the scheme explicitly.

Known cost, and what is not done

FoR's filter push-down does not apply to this encoding. Filtering renumbers rows, which breaks the row-to-block mapping, so a Filter over a BlockedFoR array materializes it rather than staying encoded. Any caller opting the scheme in trades that for the size win, and it is not benchmarked here.

Also out of scope: no fused unpack path (decode adds a separate reference-addition pass instead of folding into unchecked_unfor_pack the way FoR does), no CUDA kernel, and no specialized compare/is_sorted/is_constant/cast kernels — those decompress first. Promotion to a core edition, and with it selection by default, is a separate decision.

Testing

encodings/fastlanes/src/blocked_for/tests.rs covers round-trips across integer ptypes, nulls (including all-null blocks), non-block-aligned lengths, single-block arrays, slicing at and across block boundaries, serde, and the property the encoding exists for — blocked_references_narrow_the_bit_width asserts 7 bits blocked vs 24 global on the same data, independent of feature flags.

In vortex-btrblocks: test_blocked_for_compressed (drifting data selects it when opted in), test_blocked_for_falls_back_to_global_for (no local clustering leaves it to FoR), default_schemes_exclude_blocked_for, and retain_allowed_encodings_keeps_global_for_without_blocked.

Checks run: cargo test -p vortex-btrblocks -p vortex-fastlanes across default, pco, --all-features, and --no-default-features; cargo test -p vortex --lib editions; cargo test -p vortex-file -p vortex-layout; cargo clippy --all-targets over default, pco, zstd, --all-features, and --no-default-features; cargo +nightly fmt --all. I could not run a workspace-wide build — lance-encoding fails on a missing protoc in this container, unrelated to this change.

FoR subtracts one minimum from a whole array, so the single bit width BitPacking then picks is driven by the spread of the entire array. Data that stays tightly clustered locally but drifts over the array — sorted keys, timestamps, counters, offset vectors — pays for that spread on every value. BlockedFoR stores one reference per 1024-value block (the FastLanes chunk size), so the residual bit width is set by the widest block instead. The references live in a child array, which the cascading compressor compresses in turn; a `offset` in metadata (< 1024) keeps slicing exact, mirroring BitPacked. BlockedFoRScheme replaces FoRScheme in ALL_SCHEMES, and falls back to plain FoR whenever per-block references buy no bits: single-block arrays, block-constant arrays, and data whose blocks span the same range as the array. The CUDA preset keeps FoR, which has a GPU decode kernel. Filter push-down does not apply to this encoding: filtering renumbers rows, which breaks the row-to-block mapping. Arrays that fall back to FoR keep it. Measured on compressed array bytes at 131072-row chunks: TPC-H lineitem sf=0.1 4.17% smaller (l_orderkey 18.3%, l_comment 6.8%) ClickBench hits 1M 2.53% over the 44 columns that changed NYC taxi 2023-11 0.99% over the 4 columns that changed Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Regenerated the golden snapshots against the merged code: develop's delta estimate fix (#9602) and BlockedFoR both target the same shapes, so the unstable snapshots now match develop and only the default-feature ones change. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

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.

Two defects, one root cause: BlockedFoRScheme was registered in place of FoRScheme and declared both encodings as its output. An encoding must belong to an enabled edition before the writer will serialize it, and fastlanes.blockedfor belonged to none. Where the file writer configures an encoding policy, retain_allowed_encodings saw a scheme producing a forbidden encoding and dropped it -- taking global FoR with it, because no other scheme produced it. Integer columns that would have used a frame of reference fell back to plain bit-packing, so ClickBench files grew 0.6% overall (152 of 200 larger). Where no policy was configured, nothing filtered the scheme and the write failed outright with "Array encoding fastlanes.blockedfor not permitted by ctx", which is what the SQL logic tests hit. BlockedFoRScheme now produces only BlockedFoR and skips wherever a single global reference is the better shape, so FoRScheme rejoins ALL_SCHEMES and competes for those arrays on its own estimate. An encoding policy that forbids blockedfor now drops just the blocked scheme and keeps frame of reference, pinned by retain_allowed_encodings_keeps_global_for_without_blocked. fastlanes.blockedfor joins the new PREVIEW_2026_08_0 edition, following fastlanes.delta. Preview is only enabled with unstable_encodings, so the scheme is gated behind that feature -- selecting an encoding the writer cannot serialize fails the write. Under that feature Delta already wins these shapes after #9602, so every golden snapshot now matches develop apart from one compact list case that shifts delta -> pco and shrinks.

The only use of the import is a test that is itself gated, so building without default features warned on an unused import. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Commits: PR ee07a98a vs base 479bd98a
Verdict: No clear signal (low confidence)
Attributed Vortex impact: -0.4%
Engines: DataFusion No clear signal (-0.4%, low confidence) · DuckDB No clear signal (-0.3%, environment too noisy confidence)

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.

Gating the scheme on `unstable_encodings` did not close the hole it was meant to. That feature is per-crate: `vortex-file/unstable_encodings` turns on `vortex-btrblocks/unstable_encodings` without turning on `vortex/unstable_encodings`, and only the latter enables the preview edition. The scheme was therefore reachable in builds where `fastlanes.blockedfor` was not writable. Whether that surfaced depended on the write path. `VortexWriteOptions` derives an encoding policy from the session's editions, so there the scheme was filtered out. Paths that build a `WriteStrategyBuilder` directly -- vortex-ffi, vortex-python, vortex-tui, the CUDA writers -- leave that policy unset, nothing filters the scheme, and the write fails with "Array encoding fastlanes.blockedfor not permitted by ctx". A feature flag cannot express "this session's editions permit this encoding", so stop trying: BlockedFoRScheme leaves ALL_SCHEMES and is opted into explicitly by callers that have also enabled the preview edition. No default write path can now select an encoding its session cannot serialize, pinned by default_schemes_exclude_blocked_for. This restores ALL_SCHEMES to develop's contents exactly, so the only remaining golden change is compact__list_of_int_runs, which is stale on develop: develop's own code produces the pco offsets recorded here, as a worktree run at 5049e41 confirms.

…ession-sampling-qqbhm7

Workspace-wide clippy unifies features, so vortex-btrblocks builds with pco enabled but not unstable_encodings. In that combination both users of the ArrayRef import were compiled out and the import was left unused, failing the clippy-default lint. Inlining the helper into the test that uses it leaves ArrayRef with a single user, gated the same way, so no feature combination strands it. Verified with clippy over default, pco, zstd, all-features, and no-default-features. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

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 ee07a98a vs base 479bd98a
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -8.3%
Engines: DataFusion No clear signal (+2.2%, environment too noisy confidence) · DuckDB No clear signal (-17.6%, environment too noisy confidence)
Vortex (geomean): hot 0.919x ➖ · cold 0.958x ➖
Parquet (geomean): hot 1.002x ➖ · cold 0.952x ➖
Shifts: Parquet (control) +0.2% · Median polish -1.9%

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.

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.

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.
