mahesh kumar behera updated HIVE-23919: --------------------------------------- Description: Currently in Hive we create different operator for different kind of join. n Calcite, it all seems to be based on a single Join class in newer releases. So the classes like HiveAntiJoin, HiveSemiJoin can be merged into one. was: For Anti Join, we emit the records if the join condition does not satisfies. In case of PK-FK rule we have to explore if this can be exploited to speed up Anti Join processing. > Merge all kind of Join operator variants (Semi, Anti, Normal) into one. > ------------------------------------------------------------------------ > > Key: HIVE-23919 > URL: https://issues.apache.org/jira/browse/HIVE-23919 > Project: Hive > Issue Type: Bug > Reporter: mahesh kumar behera > Assignee: mahesh kumar behera > Priority: Major > > Currently in Hive we create different operator for different kind of join. n > Calcite, it all seems to be based on a single Join class in newer releases. > So the classes like HiveAntiJoin, HiveSemiJoin can be merged into one. > -- This message was sent by Atlassian Jira (v8.3.4#803005)
