Synopses for Query Optimization: A Space-Complexity Perspective

Summary: Information-theoretic analysis of synopsis space: histograms suffice for single-table selections but are fundamentally limited for joins. For key–foreign-key joins, small precomputed samples yield nearly space-optimal probabilistic guarantees; experiments confirm samples outperform histograms as joins increase.
