[jira] [Created] (SPARK-33177) CollectList and CollectSet should not be nullable

Tanel Kiis created SPARK-33177:
----------------------------------

             Summary: CollectList and CollectSet should not be nullable
                 Key: SPARK-33177
                 URL: https://issues.apache.org/jira/browse/SPARK-33177
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: Tanel Kiis


CollectList and CollectSet SQL expressions never return null value. Marking them as non-nullable can have some performance benefits, because some optimizer rules apply only to non-nullable expressions
