Plan Stitch: Harnessing the Best of Many Plans

Summary: Plan Stitch opportunistically stitches efficient subplans from past plans into a valid new plan cheaper than any single prior plan. Implemented on SQL Server; evaluated with TPC-DS and real workloads, achieving up to 100x cost reductions versus reverting to the cheapest previous plan. (summarized by gpt-5-nano on Feb 09 2026)
