A Step Toward Deep Online Aggregation
Summary: Introduces evolving data frames (edf) to enable online aggregation for nested op(...(op(data))), closed under set operations. Wake, an edf-based OLA system, achieves ~4.93x faster initial estimates on TPC-H and 1.3x slower exact answers, beating prior OLA and supporting set ops. (summarized by gpt-5-nano on Feb 09 2026)
