WebIntroduction. Accurate cardinality estimates are fundamental to cost-based optimizers, such as the Db2 optimizer. Cardinality estimation is a process where the optimizer traditionally uses statistics to determine the size of intermediate query results such as the output cardinality of an operator in an access plan that applies one or more predicates.
