Key: TEIID-1510
URL: https://issues.jboss.org/browse/TEIID-1510
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Labels: costing
Fix For: 7.4
RulePushAggregates currently only considers whether a key is in use in the grouping
columns to not stage an aggregate. It should additionally use a cost check to see if the
staged aggregate is cost effective.
