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.
