DB2 Query Parallelism: Staging and Implementation

Summary: Describes DB2’s three-stage intraquery parallelism, introduced in Version 3 (1993), and its implementation across optimizer, executor, buffer manager, and other components. Highlights the system-wide engineering required for practical data-intensive query speedups. (summarized by gpt-5.6-luna on Jul 24 2026)
