Benchmarks: Vortex queries 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +3.5%
Engines: DataFusion No clear signal (+5.1%, low confidence) · DuckDB No clear signal (+1.8%, low confidence)
Vortex (geomean): 1.020x ➖
Parquet (geomean): 1.003x ➖
Shifts: Parquet (control) +0.3% · Median polish +1.9%

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.
