SQL/MapReduce: A practical approach to self-describing, polymorphic, and parallelizable user-defined functions

Summary: SQL/MR: a MapReduce-inspired UDF framework for scalable, self-describing functions in parallel, shared-nothing DBs. UDFs are polymorphic; their output schemas are defined by the function at query plan-time, enabling language-agnostic, cross-schema reuse. (summarized by gpt-5-nano on Feb 09 2026)
