Wander Join: Online Aggregation via Random Walks

Summary: Wander Join uses random walks over the join graph for online aggregation, beating ripple join without precomputed statistics. Statistics-free optimizer selects walk-based plans; strong for multi-table equality and group-by, validated on TPC-H in PostgreSQL. (summarized by gpt-5-nano on Feb 09 2026)
