Steven Hawkins created TEIID-4332: ------------------------------------- Summary: Enhance costing to better guess at ndv Key: TEIID-4332 URL: https://issues.jboss.org/browse/TEIID-4332 Project: Teiid Issue Type: Quality Risk Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 9.1 Our logic for determining ndv is mostly ad hoc and varies greatly depending upon the position in the plan. This needs to be more standardized and based upon consistent assumptions - also additional information such as predicates and foreign keys should influence the calculation. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
