Optimal Aggregation Algorithms for Middleware [Extended Abstract]

Summary: Introduces TA, proved instance-optimal for top-k under any monotone aggregation on every database with only constant-size buffers. Gives optimal variants when random access is costly/impossible and contrasts TA's deterministic worst-case optimality and low memory vs. Fagin's Algorithm. (summarized by gpt-5-mini on Feb 09 2026)
