Morsel-Driven Parallelism: A NUMA-Aware Query Evaluation Framework for the Many-Core Age

Summary: Introduces morsel-driven parallelism: NUMA-aware, fine-grained tasks that schedule small data morsels to run complete operator pipelines, bypassing plan-driven load balance. Dispatcher maps morsels to NUMA-local workers, enabling elastic parallelism and achieving >30x speedup on 32 cores for TPC-H/SSB. (summarized by gpt-5-nano on Feb 09 2026)
