Coresets for Robust Query Optimization
Summary: Introduces plan coresets for robust query optimization under cardinality uncertainty, proving size bounds across cost classes. Workload-aware construction algorithms yield compact coresets with near-optimal performance despite worst-case lower bounds. (summarized by gpt-5.6-luna on Jul 26 2026)
