_{Comparing myrrc/duckdb-split-model (36c96f7) with develop (406d6a1)²}

44 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩
No successful run was found on develop (e0d5f28) during the generation of this report, so 406d6a1 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

Verdict: Likely regression (medium confidence)
Attributed Vortex impact: +123.9%
Engines: DataFusion No clear signal (+5.1%, low confidence) · DuckDB Likely regression (+376.8%, 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.

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 (environment too noisy confidence)
Attributed Vortex impact: +19.1%
Engines: DataFusion No clear signal (+15.0%, environment too noisy confidence) · DuckDB No clear signal (+23.4%, high confidence)
Vortex (geomean): 1.177x ❌
Parquet (geomean): 0.988x ➖
Shifts: Parquet (control) -1.2% · Median polish +1.3%

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: TPC-H SF=1 on S3 📖

Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +9.6%
Engines: DataFusion No clear signal (-4.3%, environment too noisy confidence) · DuckDB No clear signal (+25.4%, environment too noisy confidence)
Vortex (geomean): 1.123x ➖
Parquet (geomean): 1.025x ➖
Shifts: Parquet (control) +2.5% · Median polish +2.5%

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-DS SF=1 on NVME 📖

Verdict: Likely regression (medium confidence)
Attributed Vortex impact: +54.1%
Engines: DataFusion No clear signal (+2.6%, low confidence) · DuckDB Likely regression (+131.3%, environment too noisy confidence)
Vortex (geomean): 1.543x ❌
Parquet (geomean): 1.002x ➖
Shifts: Parquet (control) +0.2% · Median polish +1.2%

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 on NVME 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +7.6%
Engines: DataFusion No clear signal (+1.7%, low confidence) · DuckDB No clear signal (+13.9%, medium confidence)
Vortex (geomean): 1.080x ➖
Parquet (geomean): 1.004x ➖
Shifts: Parquet (control) +0.4% · 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.

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: 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.
