Tradeoffs in Processing Complex Join Queries via Hashing in Multiprocessor Database Machines

Summary: Examines hash-based processing of ~10-way joins in shared-nothing MP databases, focusing on query-tree shape and dataflow format. Shows right-deep scheduling often beats left-deep/bushy under memory limits, with new right-deep algorithms and intra-query parallelism tradeoffs. (summarized by gpt-5-nano on Feb 09 2026)
