|
|
| This collection includes: |
|
|
| - **Effi-SQL Benchmark**: a benchmark for evaluating SQL efficiency optimization methods. |
| - **Diff-SQL Training Dataset**: training data used by Diff-SQL, including data for the Patch Generator and Constraint Aligner. |
|
|
| ## Dataset Fields |
|
|
| ### Effi-SQL Benchmark |
|
|
| - **id**: A unique identifier for each benchmark instance. |
| - **db**: The database name. |
| - **base_sql**: The original slow SQL query. |
| - **optimized_sql**: The human-verified optimized SQL query. |
| - **base_time**: Execution time of the original SQL query. |
| - **fast_time**: Execution time of the optimized SQL query. |
| - **base_explain_analyze**: Query execution plan (QEP) output for the original SQL query. |
| - **optimized_explain_analyze**: Query execution plan (QEP) output for the optimized SQL query. |
| - **difficulty**: The difficulty label of the benchmark instance. |
