> 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
> Priority: Major
>
> 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.
