             Summary: Add higher order function`forall`
                 Key: SPARK-27905
                 URL: https://issues.apache.org/jira/browse/SPARK-27905
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Nikolas Vanderhoof


Add the SQL function forall.

`forall` tests an array to see if predicate holds for every item of the array.

This complements the `exists` higher order function.
