Optimizing Subgraph Queries by Combining Binary and Worst-Case Optimal Joins

Summary: Cost-based optimizer for subgraph queries with worst-case optimal plans, enabling hybrid plans that mix binary joins and multiway intersections. Introduces intersection-cost, expands plan space beyond tree decompositions, and adds adaptive reordering during execution in Graphflow DBMS. (summarized by gpt-5-nano on Feb 09 2026)
