Query Execution in DIRECT
Summary: DIRECT dynamically tunes parallelism by query priority and operation mix, with runtime reallocation via monitors and NEXT PAGE. It tackles fragmentation and estimates optimal processor counts to compress data, reducing query time on parallel DBs. (summarized by gpt-5-nano on Feb 09 2026)
