From 9a1b8a4b15c356be94e0ef5b147ef001b8096e7a Mon Sep 17 00:00:00 2001 From: Will Manning Date: Wed, 25 Mar 2026 15:38:39 -0400 Subject: [PATCH 01/89] feat[turboquant]: add TurboQuant vector quantization encoding Implement the TurboQuant algorithm (arXiv:2504.19874) as a new lossy encoding for high-dimensional vector data. This supports both the MSE-optimal and inner-product-optimal (Prod) variants at 1-4 bits per coordinate. Key components: - Max-Lloyd centroid computation on Beta(d/2,d/2) distribution - Deterministic random rotation via nalgebra QR decomposition - FastLanes BitPackedArray for index storage - QJL residual correction for unbiased inner product estimation (Prod) The encoding operates on FixedSizeList arrays of floats, which is the storage format for Vector and FixedShapeTensor extension types.

The SRHT applies D₃·H·D₂·H·D₁ where H is the Walsh-Hadamard transform and Dₖ are random diagonal ±1 sign matrices. This eliminates both the nalgebra and faer dependencies — the SRHT is fully self-contained with no external linear algebra library needed.

charset=UTF-8 Content-Transfer-Encoding: 8bit Address code review findings: - Tighten SRHT roundtrip test tolerance from 1e-3 to 1e-5 (verified exact to ~4e-7 relative error across dim 32-1024). Consolidate into parameterized rstest covering power-of-2 and non-power-of-2 dims. - Rename `pd` -> `padded_dim` throughout compress.rs and decompress.rs for clarity. - Add early dimension validation (>= 2) in turboquant_encode with clear error message. - Add edge case tests: single-row roundtrip (Mse + Prod), empty array Prod variant, dimension-below-2 rejection. - Tighten norm preservation test to 1e-5 relative tolerance. Total: 59 tests (up from 49).

At 8 bits (256 centroids), codes are stored as raw u8 instead of bit-packed since BitPackedArray doesn't support width >= 8. This gives ~4x compression from f32 with near-lossless quality (MSE bound 4.15e-05). Changes: - Update all validation sites (compress, array, centroids) to accept 1-8 bits (MSE) and 2-8 bits (Prod) - Skip bitpack_encode for 8-bit codes, store PrimitiveArray directly - Extend crate docs with full 1-8 bit bound/ratio tables - Add 6-bit and 8-bit test cases for roundtrip, MSE bounds, Prod bias, and monotonic MSE decrease. High bit-width tests verify MSE < 4-bit MSE and MSE < 1% (since the theoretical bound becomes unrealistically tight at 5+ bits due to SRHT finite-dimension effects) - Regenerate public-api.lock Total: 69 unit tests + 1 doctest.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add methods to persist and restore SRHT rotation signs as BoolArray, eliminating the need to regenerate from seed during decompression: - `export_inverse_signs_bool_array()`: Exports 3 × padded_dim sign bits as a single BoolArray in inverse-application order [D₃|D₂|D₁] so decompression iterates sequentially. - `from_bool_array(signs, dim)`: Reconstructs RotationMatrix from stored signs without needing the seed. - `apply_inverse_srht_from_bits(buf, signs_bytes, padded_dim, norm_factor)`: Hot-path free function that applies inverse SRHT directly from raw sign bytes, avoiding intermediate Vec reconstruction. Convention: bit=1 means +1, bit=0 means -1 (negate).

Validity is pushed down to the codes child via ValidityVTableFromChild at each level. Includes decompression implementations for both new types that use stored centroids/signs and the hot-path apply_inverse_srht_from_bits. The old TurboQuantArray and its decode paths are retained for now.

charset=UTF-8 Content-Transfer-Encoding: 8bit Update the BtrBlocks TurboQuant compressor to produce the new cascaded TurboQuantQJLArray(TurboQuantMSEArray) structure. The compressor no longer manually compresses each child — it produces the TurboQuant array and lets the layout writer's recursive descent handle child compression naturally. This removes the explicit per-child compress_canonical calls and the BtrBlocksCompressor self-reference, making the compressor stateless.

modules, delete dead code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Restructure the turboquant crate to follow the fastlanes encoding pattern where each encoding type gets its own subdirectory with array/ and vtable/ subdirectories: mse/ mod.rs — marker struct + re-exports array/mod.rs — TurboQuantMSEArray struct + accessors vtable/mod.rs — VTable + ValidityChild impls qjl/ mod.rs — marker struct + re-exports array/mod.rs — TurboQuantQJLArray struct + accessors vtable/mod.rs — VTable + ValidityChild impls Delete all dead code: - Remove old monolithic array.rs (TurboQuantArray, TurboQuantVariant) - Remove old mse_array.rs, qjl_array.rs flat files - Remove old rules.rs - Remove legacy decode functions from decompress.rs - Remove TurboQuantVariant from TurboQuantConfig (now just bit_width + seed) Update all consumers: - BtrBlocks compressor (already using new API) - Benchmarks: turboquant_encode → turboquant_encode_mse - lib.rs: use glob re-exports (pub use mse::*, pub use qjl::*) - Docstring example updated for new API Signed-off-by: Will Manning Co-Authored-By: Claude Opus 4.6 (1M context) Signed-off-by: Will

Fix: expand the stored BoolArray signs into f32 ±1.0 vectors once at decode start via RotationMatrix::from_bool_array(), then use the original inverse_rotate() with its SIMD-friendly apply_signs() inner loop. The expansion costs 3 × padded_dim × 4 bytes of temporary memory (12KB for dim=1024), amortized over all rows. We still store signs as 1-bit BoolArray on disk (32x space savings), but recover full autovectorized throughput at decode time. The apply_inverse_srht_from_bits function is retained (with tests) for potential future use with explicit SIMD bit-extraction intrinsics.

Eof should only be used for data that the writer wants to place at the end of the file. Buffered writer was writing regular buffered data to there which did mess up ordering of some segments. Previously struct writer was using a transposed stream without spawning a task per column, on that world buffering was deadlocky. That is changed for a while to spawn now, so we should be deadlock safe. I did try converting all clickbench files repeatedly, as well as the public bi datasets and randomly generated wide tables but I couldn't deadlock this. fixes https://github.com/vortex-data/vortex/issues/7234 fixes https://github.com/vortex-data/vortex/issues/7236 ## Testing add a vortex file test that asserts the dict layout segments are in the right order, as well as zone maps across columns --------- Signed-off-by: Onur Satici Signed-off-by: Will Manning --- vortex-file/src/tests.rs | 175 ++++++++++++++++++++++++++ vortex-layout/src/layouts/buffered.rs | 34 ++--- 2 files changed, 194 insertions(+), 15 deletions(-) diff --git a/vortex-file/src/tests.rs b/vortex-file/src/tests.rs index ee81f957bf0..5a7d93ec99c 100644 --- a/vortex-file/src/tests.rs +++ b/vortex-file/src/tests.rs @@ -62,6 +62,7 @@ use vortex_buffer::ByteBufferMut;

``` To ```rust let writer = TableStrategy::new(Arc::new(validity_strategy), Arc::new(child_strategy)); ``` **Note that TableStrategy and StructStrategy constructors have their arguments flipped** ## Testing We're eliminating code, nothing added.

For non-power-of-2 dims, the -zero-padded entries cause a distribution mismatch that elevates QJL bias from ~11% to -~23%+ and worsens with smaller dimensions. The fix is to use a rotation that produces -the correct coordinate distribution without zero-padding. - -## Approach: Tiered rotation by dimension structure - -Three tiers based on what the dimension actually is: - -| Dimension structure | Example dims | Rotation | Rationale | -|---------------------|-------------|----------|-----------| -| Power of 2 | 128, 256, 512, 1024 | SRHT (current) | No padding, exact distribution | -| Sum of 2 powers of 2 (>128) | 384, 768, 1536 | Split SRHT | Two independent SRHTs, no padding | -| Small (≤128) non-power-of-2 | 96, 100, 112 | Dense orthogonal | d² is cheap at small d | -| Other (>128) | 837, 1000 | SRHT with padding | Accept QJL bias, current behavior | - -The key insight: the common non-power-of-2 embedding dimensions (768, 384, 1536) are -almost always sums of two powers of two.

The permutation ensures both halves get a uniform mix of -the original dimensions, so both SRHTs see statistically similar inputs. - -**Why not split for arbitrary dims?** A dimension like 837 doesn't decompose into -two powers of two. We could decompose into more terms (837 = 512 + 256 + 64 + 4 + 1) -but many small SRHTs lose mixing quality. The SRHT-with-padding approach is acceptable -for these rare cases. - -**Why dense only for ≤128?** At d=128, the dense matrix is 64 KB and GEMV is 16K -FLOPS — both small. At d=768, it's 2.36 MB and 590K FLOPS — the storage is -significant and the compute gap widens. The split SRHT gives O(d log d) for -the common large non-power-of-2 dims. - -## What we tried and learned - -| Approach | 768/3-bit QJL bias | 768/4-bit QJL bias | 768/8-bit MSE | Verdict | -|----------|-------------------|-------------------|---------------|---------| -| Original (padded_dim centroids) | -0.24 | -0.22 | within bound | baseline | -| Analytical (dim centroids) | -0.15 | -0.28 | within bound | mixed | -| MC empirical centroids | passes 0.15 | +0.06 | 25× over bound | MSE regression | -| Random permutation before SRHT | -0.24 | -0.22 | within bound | no effect | - -Key takeaways: -- The bias is caused by distribution mismatch from zero-padding, not centroid tuning -- MC centroids optimize for the actual distribution but violate the theoretical MSE bound -- Fixing centroids alone trades MSE quality for QJL bias — a fundamental tension -- The principled fix is to eliminate the distribution mismatch at the rotation level - -## Verification - -1. All existing tests pass (SRHT path unchanged for power-of-2) -2. 768/384/1536 pass at 0.15 QJL bias (SplitSrht path) -3. MSE within theoretical bound for all rotation types -4. Benchmarks: SplitSrht throughput comparable to SRHT -5.
