[jira] [Created] (SPARK-33778) Allow typesafe join for LeftSemi and LeftAnti

Venkata krishnan Sowrirajan created SPARK-33778:
---------------------------------------------------

             Summary: Allow typesafe join for LeftSemi and LeftAnti
                 Key: SPARK-33778
                 URL: https://issues.apache.org/jira/browse/SPARK-33778
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.1
            Reporter: Venkata krishnan Sowrirajan


With [SPARK-21333|https://issues.apache.org/jira/browse/SPARK-21333] change, LeftSemi and LeftAnti no longer has a typesafe join API. It makes sense to not support LeftSemi and LeftAnti as part of joinWith as it returns tuples which includes values from both the datasets which is not possible in the above joins. Neverthless, it would be nice to have a separate join API or in the existing API to support LeftSemi and LeftAnti which returns Dataset.
