[jira] [Created] (IMPALA-7911) Extend constant propagation for views to include other operators

Peter Ebert created IMPALA-7911:
-----------------------------------

             Summary: Extend constant propagation for views to include other operators
                 Key: IMPALA-7911
                 URL: https://issues.apache.org/jira/browse/IMPALA-7911
             Project: IMPALA
          Issue Type: New Feature
            Reporter: Peter Ebert


IMPALA-5003 added the ability to use a view to hide from users that a table might be partitioned by month instead of day (avoiding over partitioning and small files), and works well for = operator. However if a user queries using < or > (and likely others) this does not work.  For the date example > and < are common so it would be helpful to have this extended to those.
