------------------------------------------
> Add getRowCountInt support for anti join in calcite.
> ------------------------------------------------------
>
> Key: HIVE-23933
> URL: https://issues.apache.org/jira/browse/HIVE-23933
> Project: Hive
> Issue Type: Bug
> Reporter: mahesh kumar behera
> Assignee: mahesh kumar behera
> Priority: Major
>
> The current anti join conversion does not support direct conversion of
> not-exists to anti join. The not exists sub query is converted first to left
> out join and then its converted to anti join. This may cause some of the
> optimization rule to be skipped.
