Depth Estimation for Ranking Query Optimization

Summary: DEEP estimates rank-join input depth—the key cost driver—by modeling the joint score distribution across base tables. Efficient algorithms integrate this principled, data-aware framework into optimizers, outperforming prior estimation techniques. (summarized by gpt-5.6-luna on Jul 24 2026)
