LEON: A New Framework for ML-Aided Query Optimization
Summary: LEON is an ML-aided framework that augments an expert query optimizer by training a pairwise-ranking model to self-adjust to specific deployments, replacing prior regression objectives. Combines ranking+uncertainty exploration to find valuable plans and ML-guided pruning to boost planning efficiency, improving end-to-end latency, training efficiency, and stability.
