------------------------------------------
Summary: 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
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.
