-------------------------------------

             Summary: Allow dependent join pushdown to be chosen by the planner
                 Key: TEIID-2885
                 URL: https://issues.jboss.org/browse/TEIID-2885
             Project: Teiid
          Issue Type: Enhancement
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.7


As a follow on to TEIID-2249, the planner should be able to choose when to use full join pushdown, rather than only relying upon a hint.  One downside to this currently is that there isn't a good way to do a back off to a different join processing (unless we embedded an alternative plan) and so we may have to add failure logic if too many independent values are retrieved.
