[teiid-issues] [JBoss JIRA] (TEIID-4320) Costing calculation issues

Costing calculation issues -------------------------- Key: TEIID-4320 URL: https://issues.jboss.org/browse/TEIID-4320 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.7 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Critical Fix For: 9.1, 8.7.8.6_2, 9.0.1, 8.13.6 When determining if a dependent join should be used we'll rule out too many scenarios based upon requiring additional ndv info - when that can be determined from cardinality alone. Also we are inappropriately assuming key usage in predicate costing - as it does not consider the node which may not represent a single table.
