Merging this PR will regress 1 benchmark

⚠️

Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

⚡ 2 improved benchmarks
❌ 1 regressed benchmark
✅ 1997 untouched benchmarks
⏩ 89 skipped benchmarks¹

Warning

Please fix the performance issues or acknowledge them on CodSpeed.

Performance Changes

Benchmarks: Random Access 📖

Verdict: No clear signal (medium confidence)
Attributed Vortex impact: +6.6%
Engines: random-access No clear signal (+6.6%, medium confidence)
Vortex (geomean): 1.059x ➖
Parquet (geomean): 0.994x ➖
Shifts: Parquet (control) -0.6% · Median polish +3.6%

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: -10.4%
Engines: DataFusion No clear signal (+1.4%, low confidence) · DuckDB No clear signal (-20.8%, medium 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-DS SF=1 on NVME 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +0.2%
Engines: DataFusion No clear signal (-0.2%, low confidence) · DuckDB No clear signal (+0.7%, environment too noisy confidence)
Vortex (geomean): 1.005x ➖
Parquet (geomean): 1.003x ➖
Shifts: Parquet (control) +0.3% · 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.

Benchmarks: Clickbench Sorted on NVME 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +2.3%
Engines: DataFusion No clear signal (+4.3%, low confidence) · DuckDB No clear signal (+0.3%, low confidence)
Vortex (geomean): 1.005x ➖
Parquet (geomean): 0.982x ➖
Shifts: Parquet (control) -1.8% · 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.

Benchmarks: TPC-H SF=10 on NVME 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: -0.3%
Engines: DataFusion No clear signal (-0.4%, low confidence) · DuckDB No clear signal (-0.2%, low confidence)
Vortex (geomean): 0.997x ➖
Parquet (geomean): 1.000x ➖
Shifts: Parquet (control) +0.0% · 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.

Benchmarks: FineWeb S3 📖

Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +25.5%
Engines: DataFusion No clear signal (+20.3%, environment too noisy confidence) · DuckDB No clear signal (+31.0%, environment too noisy confidence)
Vortex (geomean): 1.057x ➖
Parquet (geomean): 0.842x ➖
Shifts: Parquet (control) -15.8% · Median polish -1.0%

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: Statistical and Population Genetics 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +2.1%
Engines: DuckDB No clear signal (+2.1%, low confidence)
Vortex (geomean): 1.018x ➖
Parquet (geomean): 0.997x ➖
Shifts: Parquet (control) -0.3% · Median polish -0.5%

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 (low confidence)
Attributed Vortex impact: -3.7%
Engines: DataFusion No clear signal (-5.3%, environment too noisy confidence) · DuckDB No clear signal (-2.1%, low confidence)
Vortex (geomean): 0.921x ➖
Parquet (geomean): 0.957x ➖
Shifts: Parquet (control) -4.3% · Median polish -3.9%

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.
