Add TakeSlices for fixed-size-list take by danking · Pull Request #8674 · vortex-data/vortex

danking · 2026-07-07T16:30:28Z

The key issue here is that fixed_size_list.take(indices) explodes the indices into one index per list element. For a fixed-size list of length 4096, this means the number of take indices expands by three orders of magnitude. Moreover, the take kernel must either copy each index separately or reconstruct the fact that these are actually contiguous ranges so it can use range copies.

This PR now models that operation directly as a gather of contiguous runs:

fn take_slices(&self, starts: ArrayRef, lengths: ArrayRef) -> VortexResult<ArrayRef>;

starts[i] and lengths[i] describe each child run, and the output is the concatenation of values[starts[i]..starts[i] + lengths[i]]. The runs may overlap, repeat, and appear in any order; this is a gather of runs, not a normal slice.

For FixedSizeList<100, u8>, this:

fixed_size_list.take([10, 100, 0])

now becomes run selectors over the child elements:

starts  = [1000, 10000, 0]
lengths = [100, 100, 100]

instead of expanding to:

fixed_size_list.elements().take([1000, 1001, ..., 1099, 10000, 10001, ..., 10099, 0, 1, ..., 99])

This also gives ListView -> List packing a direct fast path: ListView rebuild now uses original offsets as starts and normalized sizes as lengths, so it can gather the referenced element runs without building a flat per-element take index buffer or falling back to per-list builders. Struct now pushes those run selectors into each field, and VarBinView now executes run gathers by copying contiguous view ranges while reusing the original data buffers.

This is a table of results for FixedSizeList<N, f16>:

Summary

Switch TakeSlicesArray from a Vec<Range<usize>> constructor to selector arrays: non-nullable unsigned starts and lengths.
Route FixedSizeList take through contiguous child runs via take_slices, leaving child encodings responsible for optimization.
Add selector validation/materialization helpers for equal-length, non-nullable unsigned selectors and in-bounds runs, including zero-length runs.
Add a primitive TakeSlicesExecute kernel that copies each requested run directly from the primitive slice.
Add Struct TakeSlicesReduce so run gathers push down into each field, matching the existing take shape.
Add VarBinView TakeSlicesExecute so run gathers copy view ranges directly and reuse backing data buffers.
Use take_slices to rebuild non-zero-copy ListViewArray layouts into packed, zero-copy-to-list layouts.
Expand take_fsl benchmarks and take_slices coverage for selector arrays, overlapping/repeated runs, empty runs, nested TakeSlices, nullable validity, generic fallback, primitive execution, Struct pushdown, VarBinView view-buffer execution, and FSL take.

Correctness and Coverage

TakeSlices validates public construction selectors before creating the lazy array.
Generic TakeSlices execution repeatedly slices the child and appends each run; specialized children can bypass that path.
Nullable FSL take uses zero-length runs for null output rows and keeps nullness in outer FSL validity.
ListView rebuild zeroes null-list lengths before gathering elements, preserving packed offsets without copying invalid-row payloads.
Struct preserves struct-level validity while applying the same run selectors to every unmasked field.
VarBinView preserves validity and shares the original data-buffer Arc while copying only selected views.

PR Review: Add `TakeSlices` for fixed-size-list take

I reviewed the new TakeSlices encoding, the FSL take routing, the ListView rebuild fast path, the primitive kernel, and the validity plumbing. Overall this is a well-structured change with strong test coverage. The core "gather of contiguous runs" model is sound, selector validation is thorough, and the case-splitting in FSL take follows the repo's "dispatch to named helpers" guideline nicely. I found no correctness bugs — a few notes and questions below.

Correctness — verified, no bugs found

Null-row bounds safety in ListView rebuild is correct (worth calling out). In rebuild_with_take_slices (listview/rebuild.rs:149), null rows zero their sizes (→ length-0 runs) but pass the original, unmodified offset as the run start. A length-0 run makes selector_slices_typed check end = start + 0 = offset <= child_len. This is only safe because ListViewData::validate (listview/array.rs:731) enforces offset[i] + size[i] <= elements_len for all rows including null ones, so offset <= elements_len always holds. Good — but this now depends on that invariant for well-formedness, so it's load-bearing. A one-line comment at rebuild.rs:184 noting "null-row offset is in bounds by the ListView offset invariant" would help the next reader (and defend against a future new_unchecked caller that violates it).

Run splitting in project_slices preserves semantics. Composing TakeSlices(TakeSlices(child)) can split one outer run across multiple inner runs, increasing the row count while preserving the concatenation. Since output length is the sum of run lengths (not row count), this is correct, and the take_slices_of_take_slices_projects_to_original_child test confirms it.

Zero-length run handling is consistent across paths. selector_slices drops zero-length runs, while Validity::take_slices / the lazy validity path use the raw selectors — both yield the same logical length because empty runs contribute nothing. values and validity therefore stay aligned. Nice.

Notes / questions (non-blocking)

scalar_at is O(num_runs) per call (take_slices/vtable.rs:198). Each call re-runs selector_slices (which executes both selector arrays and allocates a Vec) and then linearly scans runs to locate the logical index. For a transient node executed in bulk this is fine, but sequential scalar iteration over a TakeSlices would be O(num_runs · accesses) — the exact "hidden-cost accessor" pattern CLAUDE.md warns about. Worth a doc note that callers should execute in bulk rather than scalar-iterate. Fix this →
TakeSlices is intentionally non-serializable (vtable.rs:155/:162 both vortex_bail!). FSL take and ListView rebuild now return arrays whose element child is a lazy TakeSlices (e.g. take.rs:308). Can you confirm every serialization/IPC path canonicalizes or executes before writing, so a lazy TakeSlices can never reach serialize? If there's any path that persists a child array without executing it, this would surface as a runtime bail. A test that round-trips an FSL-take result through the file writer would lock this down.
Signed indices reinterpreted to unsigned (fixed_size_list/compute/take.rs:56). The comment says "values are unchanged", but a negative signed index becomes a large unsigned value that then fails check_index_in_bounds with an out-of-bounds error rather than a "negative index" error. Behavior is acceptable (negative take indices are invalid), but the comment is slightly misleading for the negative case — consider rewording to "bit-identical reinterpret; negative inputs become large unsigned and are rejected by the bounds check."
Minor redundancy / cheap cleanup:
- primitive_selector_slices (take_slices/mod.rs:174) re-checks starts.len() == lengths.len(), already validated by check_selector_arrays at :145. Harmless.
- rebuild_with_take_slices calls self.validity()? three times (:172, :193, :205). It's a cheap clone, but hoisting once would be marginally cleaner.
- Primitive::take_slices recomputes the output len by folding over slices (take_slices.rs:29) even though selector_output_len already encodes this logic; not worth refactoring, just noting the duplication.

Tests

Coverage is strong: order/duplicates/overlap, nullable child validity, lazy scalar+validity, single-run reduction, size-1 repeat, all-invalid, empty runs, empty child, invalid-run rejection, nested TakeSlices projection, generic (non-primitive) fallback, and the primitive execute kernel. FSL take adds nullable, degenerate (list_size==0), and empty-source cases. This matches the branching in the implementation well.

One suggestion: add an explicit test for nullable indices over a non-nullable FSL array (null index → null output row, output dtype becomes nullable) if not already covered in fixed_size_list/tests/take.rs — that's the one interaction where output nullability is derived from indices rather than the array.

Performance

The reported CodSpeed regressions (slice_empty_vortex -15.8%, chunked_varbinview_opt_canonical_into -10.6%) touch vortex-buffer slicing and varbinview canonicalization — neither is on any path this PR changes, so they read as measurement noise rather than a real regression. The take_fsl_* numbers in the PR body (up to ~69× over per-index) are the meaningful result and match the design.

Verification I did not run

This is a read-only review; I did not run cargo build/nextest/clippy locally. The PR body lists those as passing.

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.

Introduce a lazy TakeSlices array for ordered child ranges, wire FixedSizeList take to emit element ranges, and add a primitive child execution kernel for contiguous range copies. Expand FSL take benchmarks and cover TakeSlices edge cases, nullable validity, generic slice-based execution, and nullable FSL take with nullable indices. Signed-off-by: Daniel King <dan@spiraldb.com>

Refactor fixed-size-list take around structural cases, tighten TakeSlices validation, and extend edge-case coverage. Also document the local-reasoning guideline that would have avoided threading fallback state through the main path. Signed-off-by: Daniel King <dan@spiraldb.com>

Replace ambiguous ordered-range wording with caller-provided sequence terminology so the API docs do not imply sorted or disjoint ranges. Signed-off-by: Daniel King <dan@spiraldb.com>

Switch TakeSlices to starts/lengths selector arrays and reuse the contiguous-run gather for ListView rebuilds. Signed-off-by: Daniel King <dan@spiraldb.com>

Attributed Vortex impact: -3.5%
Engines: DataFusion No clear signal (-1.9%, environment too noisy confidence) · DuckDB No clear signal (-5.0%, 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.

Benchmarks: TPC-H SF=10 on NVME

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +0.9%
Engines: DataFusion No clear signal (+1.7%, low confidence) · DuckDB No clear signal (+0.1%, low confidence)
Vortex (geomean): 1.018x ➖
Parquet (geomean): 1.002x ➖
Shifts: Parquet (control) +0.2% · 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.

Parquet (geomean): 1.004x ➖

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.

Benchmarks: TPC-H SF=1 on S3

Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +3.8%
Engines: DataFusion No clear signal (+4.3%, environment too noisy confidence) · DuckDB No clear signal (+3.4%, environment too noisy confidence)
Vortex (geomean): 1.040x ➖
Parquet (geomean): 1.001x ➖
Shifts: Parquet (control) +0.1% · Median polish +2.1%

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.

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +4.0%
Engines: DataFusion No clear signal (+10.0%, low confidence) · DuckDB No clear signal (-0.9%, 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.

Parquet (geomean): 1.018x ➖

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.

Validate existing converted Vortex files against the source Parquet footer row count before reusing them. Regenerate files that are unreadable or have stale row counts so benchmark data caches cannot preserve empty Vortex artifacts. Signed-off-by: Daniel King <dan@spiraldb.com>

Add context-aware TakeSlices construction and validity paths so callers with an ExecutionCtx do not fall back to legacy session execution. Centralize run selector validation/output length in RunSelectors and use it from execution kernels.\n\nClarify that TakeSlices remains a lazy non-serializable compute encoding like Slice, remove the unrelated AGENTS.md guidance change, tighten Struct length derivation, document the FSL null-placeholder run invariant, and rename the benchmark cache helper to describe its row-count-only check.

I don't think we should do this validation on construction. As long as starts, lengths are correct size then starts being out of bounds should be an execution error

this really should account for constant arrays, that's what you end up with for fixedsizelist
