[teiid-issues] [JBoss JIRA] Created: (TEIID-746) Composite keys should be detected by costing

Composite keys should be detected by costing -------------------------------------------- Key: TEIID-746 URL: https://jira.jboss.org/jira/browse/TEIID-746 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 6.2.0 Detection of composite keys in costing logic has not worked since we break the criteria up prior to cost analysis. A possible fix for this is to also re-combine criteria that has been pushed to a source node - this approach will still fail to detect the key criteria if one of the conjuncts cannot be pushed. Also we should be able to detect disjunctive composite key usage more broadly. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
