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 (environment too noisy confidence)
Attributed Vortex impact: -4.4%
Engines: DataFusion No clear signal (+36.1%, environment too noisy confidence) · DuckDB No clear signal (-32.8%, 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-DS SF=1 on NVME 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +2.0%
Engines: DataFusion No clear signal (-0.5%, low confidence) · DuckDB No clear signal (+4.5%, environment too noisy confidence)
Vortex (geomean): 1.021x ➖
Parquet (geomean): 1.002x ➖
Shifts: Parquet (control) +0.2% · Median polish -0.0%

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.
