Sampling-Based Query Re-Optimization

Summary: Sampling-based, low-cost post-processing detects likely cardinality-estimation errors in an optimizer’s plan and iteratively re-optimizes it with targeted sampling. Minimal integration burden—no changes to optimizer or evaluator—and low overhead demonstrated on PostgreSQL and two commercial systems. (summarized by gpt-5-nano on Feb 09 2026)
