Query Optimization in the Presence of Foreign Functions

Summary: Optimizes queries with foreign functions and external data by introducing a declarative rule language for foreign-function semantics. Generates the equivalent query space, adapts dynamic-programming join ordering, and extends the cost model for foreign functions. (summarized by gpt-5-nano on Feb 09 2026)
