Databricks researchers have explored using Large Language Model (LLM) agents to tackle the complex problem of SQL join order optimization. Traditional query optimizers often struggle with this due to the exponential growth of possible execution plans. The experimental LLM agent, acting as a data-driven DBA, demonstrated improved performance over the existing Databricks optimizer in 80% of benchmark cases, resulting in a 1.3x average reduction in query latency.
