Prefetch list elements from block boundaries by mhk197 · Pull Request #9052 · vortex-data/vortex

mhk197 · 2026-07-29T10:48:07Z

Summary

persist cumulative outer-row and element-row boundaries for structural list input blocks
use those boundaries for exact list scan splits and to issue broad element reads concurrently with offsets
trim prefetched elements to the exact range once offsets resolve, while retaining the sequential path for narrow selections and legacy files

Motivation

Nested structural-list reads currently have to resolve offsets before they can issue the corresponding element read. Deeply nested lists have several steps of sequential io to fetch offsets and then elements. Coarse paired boundaries provide a safe element envelope so broad reads can overlap these operations without flattening the list layout.

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +2.8%
Engines: DataFusion No clear signal (+1.8%, low confidence) · DuckDB No clear signal (+3.7%, low 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.

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: 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: Clickbench Sorted on NVME 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +3.2%
Engines: DataFusion No clear signal (+5.3%, low confidence) · DuckDB No clear signal (+1.1%, low confidence)
Vortex (geomean): 1.056x ➖
Parquet (geomean): 1.023x ➖
Shifts: Parquet (control) +2.3% · Median polish +4.1%

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: Likely improvement (high confidence)
Attributed Vortex impact: -24.9%
Engines: DuckDB Likely improvement (-24.9%, high 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.

Engines: DataFusion No clear signal (-4.5%, environment too noisy confidence) · DuckDB No clear signal (+0.5%, low confidence)
Vortex (geomean): 0.982x ➖
Parquet (geomean): 1.002x ➖
Shifts: Parquet (control) +0.2% · Median polish +1.1%

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.
