Use a per-benchmarks baseline instead of the last fully succesful run

[AdamGS]

Summary

Currently - when one post-merge benchmarks fails for any reason, the baseline we use is the last fully successful run. This PR changes it to be the last successful run of that specific benchmark.

Tested this works by running it in such a state and visually verifying the results.

_{Comparing adamg/benchmarks-baseline (6a4663d) with develop (47d2041)}

[github-actions]

Benchmarks: PolarSignals Profiling

Vortex (geomean): 0.969x ➖

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: +1.9%
Engines: DataFusion No clear signal (+2.3%, low confidence) · DuckDB No clear signal (+1.5%, low confidence)

Parquet (geomean): 1.049x ➖
Shifts: Parquet (control) +4.9% · Median polish +5.0%

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.

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +14.7%
Engines: DataFusion No clear signal (+27.3%, environment too noisy confidence) · DuckDB No clear signal (+3.4%, environment too noisy confidence)

Shifts: Parquet (control) -1.0% · Median polish -2.0%

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: Clickbench on NVME

Verdict: No clear signal (low confidence)
Attributed Vortex impact: -1.2%
Engines: DataFusion No clear signal (-1.2%, environment too noisy confidence) · DuckDB No clear signal (-0.7%, low confidence)
Vortex (geomean): 1.019x ➖
Parquet (geomean): 1.027x ➖
Shifts: Parquet (control) +2.7% · 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.

[github-actions]

Benchmarks: TPC-H SF=1 on S3

Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +11.2%
Engines: DataFusion No clear signal (+29.0%, environment too noisy confidence) · DuckDB No clear signal (-4.1%, environment too noisy confidence)
Vortex (geomean): 1.125x ➖
Parquet (geomean): 1.012x ➖
Shifts: Parquet (control) +1.2% · Median polish +5.0%

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.

Vortex (geomean): 0.909x ➖
Parquet (geomean): 0.983x ➖

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.
