Steven Hawkins created TEIID-5420: ------------------------------------- Summary: Costing can over estimate join cardinality when no keys nor ndv is specified Key: TEIID-5420 URL: https://issues.jboss.org/browse/TEIID-5420 Project: Teiid Issue Type: Quality Risk Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 11.1 The changes from TEIID-4485 allow for joins lacking all but cardinality information to have their cardinality over-estimated. The estimate should be made more cautious by default as that would be the most common case. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
