Key: TEIID-3917
URL:
https://issues.jboss.org/browse/TEIID-3917
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 9.0
Currently the pushProjection check in RuleAssignOutputElements does not consider
projected columns from a node that has window functions. This should be relaxed so that
more can be pushed.
