This option allows you to control the minimum number of rows a table (or a UNION ALL view of tables) must have left after the filtering effects of all local predicates have been considered before the join optimizer considers using either the hash push-down join (HPDJ) or the sort/merge push-down join (SMPDJ) algorithms for situations where there are no joins or only lookup joins between this join and the table (or the UNION ALL view). Under most circumstances you do not need to change the value of this option.
