On Parallel Processing of Aggregate and Scalar Functions in Object-Relational DBMS

Summary: Framework for data-parallel processing of user-defined functions in OR-DBMS; identifies partitionable functions for parallel execution. Adds parallel-sorting to speed broader function families; enables faster decision-support on large data. (summarized by gpt-5-nano on Feb 09 2026)
