Query Caching and Optimization in Distributed Mediator Systems

Summary: Proposes cost-based optimization for mediator systems over distributed sources by caching actual call stats to estimate plan costs. Adds a query-result cache and invariants to use semantic source info to reuse prior results when sources are unavailable, with experiments. (summarized by gpt-5-nano on Feb 09 2026)
