QPipe: A Simultaneously Pipelined Relational Query Engine

Summary: On-demand simultaneous pipelining (OSP) enables proactive sharing of operator work across concurrent queries. QPipe, an operator-centric engine with per-operator micro-engines, uses OSP for cross-query data sharing, yielding ~2x speedup on TPC-H. (summarized by gpt-5-nano on Feb 09 2026)
