CorrBound: Cardinality Estimation Accounting for Inter- and Intra-relation Correlations

Summary: CorrBound is a cardinality estimator that explicitly models inter-/intra-relation join-column correlations via a new information inequality and LP over stats + Shannon constraints, extending beyond LpBound. Sketching and low-rank tensor compression make the correlation-aware estimates practical for multi-join, range, and group-by queries. (summarized by gpt-5-mini on Apr 11 2026)
