Efficient Denial Constraint Discovery with Hydra
Summary: Hydra automatically discovers all valid denial constraints, unifying diverse integrity constraints and business rules. Its novel algorithm reduces tuple-scaling from quadratic to empirically linear, yielding orders-of-magnitude speedups over prior DC discovery methods. (summarized by gpt-5.6-luna on Jul 24 2026)
