> Addition of forany and forall semantics to Spark Dataframes
> -----------------------------------------------------------
>
> Key: SPARK-37171
> URL: https://issues.apache.org/jira/browse/SPARK-37171
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: Dhiren Navani
> Priority: Minor
>
> Spark dataframes currently do not have semantics of forany and forall.
> Scala collections do have these semantics.
> It would be nice to have them as an API as there is potential for implementing them in unoptimized form.
>
> E.g. forany might be implemented as df.filter(<condition>).count > 0, which is not optimal
