DunceCap: Query Plans Using Generalized Hypertree Decompositions
Summary: Query plans are cast as generalized hypertree decompositions and scored by minimal fractional hypertree width to bound worst-case join runtimes. Benchmarked on Stanford Large Network Dataset Collection, DunceCap rivals LogicBlox on cyclic queries. (summarized by gpt-5-nano on Feb 09 2026)
