CS2: A New Database Synopsis for Query Estimation

Summary: CS2 proposes Correlated Sample Synopsis for accurate join and selection estimation using correlated samples to preserve join structure with storage. Introduces reverse sampling and a reverse estimator; unbiased, competitive with baselines at the same space. (summarized by gpt-5-nano on Feb 09 2026)
