Scalable Discovery of Unique Column Combinations

Summary: Ducc scales discovery of all unique and non-unique column combinations by framing it as a graph-coloring problem and applying a hybrid column-based DFS/random-walk pruning. Row-based pruning with scale-out deployment yields up to 631× faster than Gordian and 398× faster than HCA on multi-million-row datasets. (summarized by gpt-5-nano on Feb 09 2026)
