Reducing Multidatabase Query Response Time By Tree Balancing
Summary: Two-phase optimization for multidatabase queries: build an optimal left-deep join tree, then balance with simple transformations for lower latency. Balancing lowers response time and resource use for sort-merge/hash-join plans, with low overhead. (summarized by gpt-5-nano on Feb 09 2026)
