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\u00a0of assumptions, such as independence between predicates, to estimate selectivity. While such techniques have the benefit of fast estimation and small\u00a0memory footprint, they often incur large selectivity estimation errors.\u00a0In this
