[jira] [Created] (SPARK-22152) Add Dataset flatten function

Drew Robb created SPARK-22152:
---------------------------------

             Summary: Add Dataset flatten function
                 Key: SPARK-22152
                 URL: https://issues.apache.org/jira/browse/SPARK-22152
             Project: Spark
          Issue Type: Wish
          Components: Spark Core
    Affects Versions: 2.2.0
            Reporter: Drew Robb
            Priority: Minor


Currently you can use an identify flatMap to flatten a Dataset, for example to get from a Dataset[Option[T]] to a Dataset[T], but adding flatten directly would allow for a more similar API to scala collections.
