[jira] [Created] (IMPALA-9971) Use defined tabled constraints during query planning

Shant Hovsepian created IMPALA-9971:
---------------------------------------

             Summary: Use defined tabled constraints during query planning
                 Key: IMPALA-9971
                 URL: https://issues.apache.org/jira/browse/IMPALA-9971
             Project: IMPALA
          Issue Type: New Feature
          Components: Frontend
            Reporter: Shant Hovsepian


With the implementation of [IMPALA-3531|https://issues.apache.org/jira/browse/IMPALA-3531] the planner now has access to defined table constraints. The Hive metastore supports defining nullability, uniquness, and referential integrity constraints. This metadata should be used for more effective query planning.
