StructReader::partition_expr doesn't hold lock if the expression is being newly partitioned

[robert3005]

We also simplify ExactExpr hash behaviour to match the equality semantics and
avoid deep tree hashing

[robert3005]

Not sure if this is better, we can redundantly recompute partitioning at the beginning but lookups no longer take a write lock

Benchmarks: Vortex queries 📖

Verdict: No clear signal (medium confidence)
Attributed Vortex impact: -4.6%
Engines: DataFusion Likely improvement (-9.3%, medium confidence) · DuckDB No clear signal (+0.3%, low confidence)
Vortex (geomean): 0.950x ➖
Parquet (geomean): 0.973x ➖
Shifts: Parquet (control) -2.7% · Median polish -2.7%

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: -2.6%
Engines: DataFusion No clear signal (-3.9%, low confidence) · DuckDB No clear signal (-1.3%, low confidence)
Vortex (geomean): 0.984x ➖
Parquet (geomean): 1.010x ➖
Shifts: Parquet (control) +1.0% · 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.

Verdict: No clear signal (low confidence)
Attributed Vortex impact: -0.4%
Engines: DuckDB No clear signal (-0.4%, low 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: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -4.1%
Engines: DataFusion No clear signal (-4.8%, environment too noisy confidence) · DuckDB No clear signal (-3.3%, low confidence)
Vortex (geomean): 0.974x ➖
Parquet (geomean): 1.016x ➖
Shifts: Parquet (control) +1.6% · Median polish -2.3%

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=10 on NVME 📖

Verdict: No clear signal (low confidence)
Attributed Vortex impact: -1.9%
Engines: DataFusion No clear signal (-2.4%, environment too noisy confidence) · DuckDB No clear signal (-1.4%, low confidence)
Vortex (geomean): 0.965x ➖
Parquet (geomean): 0.981x ➖
Shifts: Parquet (control) -1.9% · 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.

Verdict: No clear signal (low confidence)
Attributed Vortex impact: -0.8%
Engines: DataFusion No clear signal (-1.7%, environment too noisy confidence) · DuckDB No clear signal (-0.9%, low 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-H SF=1 on S3 📖

Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -3.1%
Engines: DataFusion No clear signal (-4.3%, environment too noisy confidence) · DuckDB No clear signal (-1.8%, low confidence)
Vortex (geomean): 0.986x ➖
Parquet (geomean): 1.017x ➖
Shifts: Parquet (control) +1.7% · 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: Appian 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 (+0.0%, low confidence)
Vortex (geomean): 0.929x ➖
Parquet (geomean): 0.929x ➖
Shifts: Parquet (control) -7.1% · Median polish -7.4%

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.

Parquet (geomean): 1.036x ➖

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.
