Julian Hyde commented on CALCITE-328: ------------------------------------- Since we added SemiJoin in CALCITE-368 we will probably never add {{eliminateRightDuplicates}}, though it would help us with NOT EXISTS (see CALCITE-374). > Introduce semi-join-like flag in JoinRelBase > -------------------------------------------- > > Key: CALCITE-328 > URL: https://issues.apache.org/jira/browse/CALCITE-328 > Project: Calcite > Issue Type: Bug > Reporter: Laljo John Pullokkaran > Assignee: Julian Hyde > > Introduce a flag to indicate that duplicates are eliminated from RHS of the > join (semiJoin). This would help to improve cardinality, cost estimation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
