             Summary: Allow join grouping to optimize across left outer joins
                 Key: TEIID-4886
                 URL: https://issues.jboss.org/browse/TEIID-4886
             Project: Teiid
          Issue Type: Enhancement
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 9.3


In a from clause such as:

(a.t1 inner join b.t1 ... inner join a.t2 ...) left outer join b.t2 ...

It is possible to group the b.t1 and b.t2 together, but generally won't be found by the grouping and then ordering logic.
