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

             Summary: Multi-way join predicate inappropriately removed
                 Key: TEIID-4448
                 URL: https://issues.jboss.org/browse/TEIID-4448
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 8.7
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Blocker
             Fix For: 9.1, 9.0.5


In a situation where copy criteria can work against a multi-way join predicate, such that the predicate is not pushed:

t1.a = coalesce(t2.b, t3.c, t4.d) ... t1.a = t4.d

The multi-way predicate can be marked as optional and removed.
