             Summary: common table expression performance
                 Key: TEIID-2338
                 URL: https://issues.jboss.org/browse/TEIID-2338
             Project: Teiid
          Issue Type: Enhancement
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins


Large common table expressions should be indexed based upon their usage in the query to improve performance.

Also given that we will now back-off of bad dependent joins, we should be more optimistic with using common tables as dependent joins (which would also reduce the need for an index).
