Steven Hawkins created TEIID-4885: ------------------------------------- Summary: Costing issues Key: TEIID-4885 URL: https://issues.jboss.org/browse/TEIID-4885 Project: Teiid Issue Type: Quality Risk Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 9.3 There were several deficiencies introduced with TEIID-4332 - In some circumstances very low ndv values on the large side of a join would cause a dependent join in an unexpected direction. The row estimate derived for a join without ndv information would tend to be too low, which would have a cumulative effect through further joins. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
