Computing Join Queries with Functional Dependencies
Summary: Algorithm that computes joins with functional dependencies within the GLVV polymatroid output-size bound up to polylog factors, achieving worst-case optimality when GLVV is tight. Extends GLVV via the lattice of FD-closed sets, proves tightness on distributive lattices, handles degree/cardinality bounds, and turns polymatroid proofs into algorithms.
