---------------------------------------------------
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.
