Wander Join: Online Aggregation for Joins

Summary: Wander Join proposes random-walk online aggregation for joins, replacing costly ripple-join methods and relaxing order constraints. It traverses the join graph with random walks to yield continuous, approximate results, with PostgreSQL implementation. (summarized by gpt-5-nano on Feb 09 2026)
