Featurized-Decomposition Join: Low-Cost Semantic Joins with Guarantees

Summary: FDJ uses LLM-extracted features combined as conjunctive-normal-form filters to prune semantic-join pairs before expensive predicate evaluation. It handles feature dependencies to provide statistical quality guarantees, achieving up to 10× lower cost than embedding-based methods. (summarized by gpt-5.6-luna on Aug 28 2026)
