Request Window: an Approach to Improve Throughput of RDBMS-based Data Integration System by Utilizing Data Sharing Across Concurrent Distributed Queries

Summary: Request Window detects and exploits cross-query data sharing by coalescing similar remote requests into a single fetch, enabling result reuse. Implemented in IGNITE (PostgreSQL extension); distributed TPC-H shows ~1.7× throughput gain vs a commercial data integration system. (summarized by gpt-5-nano on Feb 09 2026)
