SemJoin optimizes LLM-based semantic joins with dynamic routing

Researchers have developed SemJoin, a novel approach to optimize semantic joins in relational databases using large language models (LLMs). This system employs an LLM-based decision pipeline to dynamically route joins to either a Cluster Join strategy, which uses embedding clustering and sample-based filtering, or a Classifier strategy for predicates with discrete label sets. Tested on three diverse datasets, SemJoin consistently identified the optimal execution strategy, outperforming existing methods like adaptive block join (ABJ) and featurized-decomposition join (FDJ) in terms of F1 scores and token efficiency.
