Scalable Discovery of Unique Column Combinations

Summary: Ducc discovers all unique and non-unique column combinations by framing uniqueness as graph coloring and combining hybrid lattice traversal with row-based pruning. Parallel scale-up/out enables million-row, hundreds-attribute datasets, outperforming prior methods by up to 631×. (summarized by gpt-5.6-luna on Jul 24 2026)
