Selectivity estimation for range predicates using lightweight models
Proceedings of the VLDB Endowment, pp. 1044-1057, 2019.
Query optimizers depend on selectivity estimates of query predicates to produce a good execution plan. When a query contains multiple predicates, today's optimizers use a variety of assumptions, such as independence between predicates, to estimate selectivity. While such techniques have the benefit of fast estimation and small memory foot...More
