Databricks, in collaboration with University of Pennsylvania, investigates whether frontier LLM agents can improve join order optimization in relational databases. The research explores applying AI models to help query optimizers select efficient execution orders for complex SQL queries. Preliminary experimental results are presented from this applied AI research.
