[GitHub] [hive] maheshk114 opened a new pull request #1459: HIVE-23928 : Support conversion of sub query with not-exists to Anti join directly
maheshk114 opened a new pull request #1459:
URL: https://github.com/apache/hive/pull/1459
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.
