Allow for non-virtual dependent joins to be created over unions ---------------------------------------------------------------- Key: TEIID-5374 URL: https://issues.jboss.org/browse/TEIID-5374 Project: Teiid Issue Type: Bug Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 11.0, 10.3.2, 10.2.3 A simple structure like: {code} join access union access access {code} will reject creating a cost based dependent join over the union if the number of independent values seems too large for a virtual dependent join. A related issue is that TEIID-5020 introduced a regression when creating a dependent join that is eventually pushed over a union below an access node: {code} dependent select access set op .. {code} the logic attempts to move nested dependent select back above the access node - so that only a single dependent predicate exists - based upon the node that is created at a child. However if the child projects a literal into the dependent set criteria, then the result is invalid.
