Herman van Hovell created SPARK-18601:
-----------------------------------------

             Summary: Simplify Create/Get complex expression pairs in optimizer
                 Key: SPARK-18601
                 URL: https://issues.apache.org/jira/browse/SPARK-18601
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Herman van Hovell
            Assignee: Eyal Farago


It often happens that a complex object (struct/map/array) is created only to get elements from it in an subsequent expression. We can add an optimizer rule for this.
