BASE: Bridging the Gap between Cost and Latency for Query Optimization
Summary: BASE: two-stage RL optimizer—train policy on cheap cost signals then transfer a calibrated reward function via an inverse-RL variant to align the policy to latency without costly online execution. Mutual reward–policy refinement improves latency over cost-only learners, cuts training time ≈30% vs SOTA, and generalizes to boost other learned optimizers. (summarized by gpt-5-mini on Feb 09 2026)
