Congressional Samples for Approximate Answering of Group-By Queries

Summary: Proposes congressional samples, a hybrid of uniform and biased samples, to maximize group-by accuracy under fixed space. One-pass construction with incremental maintenance without accessing the base relation, plus query-rewriting strategies, validated on TPC-D. (summarized by gpt-5-nano on Feb 09 2026)
