Massively Parallel Sort-Merge Joins in Main Memory Multi-Core Database Systems

Summary: Introduces NUMA-affine massively parallel sort-merge joins using partial partition-based sorting, avoiding the traditionally serial final merge. On 1-TB/32-core hardware, MPSM scales nearly linearly and beats state-of-the-art parallel hash joins by up to 4×. (summarized by gpt-5.6-luna on Jul 24 2026)
