Eager Aggregation and Lazy Aggregation
Summary: Eager aggregation partially pushes a group-by below a join to shrink join input, while preserving the original group-by above. Lazy aggregation pulls a group-by above a join and merges group-bys for grouped-view reuse; experiments on TPC-D show gains. (summarized by gpt-5-nano on Feb 09 2026)
