Conjunctive Queries with Inequalities Under Updates

Summary: IEDyn dynamically maintains conjunctive queries with theta-joins under updates, avoiding materialization and recomputation. It generalizes Dynamic Yannakakis to theta-joins and extends acyclicity/free-connexity, achieving two orders of magnitude gains. (summarized by gpt-5-nano on Feb 09 2026)
