Understanding and Detecting Query Performance Regression in Practical Index Tuning: [Experiments & Analysis]

Summary: Analyze structural plan-pair changes induced by recommended indexes and show most significant QPRs stem from a small set of recurring regression patterns. Propose a pattern-based QPR detector that outperforms ML alternatives across benchmarks and real workloads. (summarized by gpt-5-mini on Feb 11 2026)
