DunceCap: Compiling Worst-Case Optimal Query Plans
Summary: DunceCap is a query compiler that combines Yannakakis' acyclic-join algorithm with a universal worst-case optimal planner to produce end-to-end optimal plans. It yields order-of-magnitude gains over standard RDBMS and simple WCO baselines on diverse multiway-join workloads. (summarized by gpt-5-nano on Feb 09 2026)
