Proactive Re-optimization with Rio
Summary: Rio uses uncertainty intervals around statistics in plan enumeration and costing to pick robust plans or defer decisions. It collects intermediate-subexpression statistics during execution for rapid re-optimization; prototype built on Predator demonstrates viability. (summarized by gpt-5-nano on Feb 09 2026)
