QOVIS: Understanding and Diagnosing Query Optimizer via a Visualization-assisted Approach

Summary: QOVIS reconstructs transformation logic among thousands of plans produced by optimizers, visualizing operator-level changes to pinpoint root causes of optimizer bugs. Validated on Spark/Hive/DuckDB; a 24-participant study shows substantial debugging speedups. (summarized by gpt-5-mini on Feb 09 2026)
