Summary: Prevent processing cross joins with unknown cardinalities
Key: TEIID-3237
URL: https://issues.jboss.org/browse/TEIID-3237
Project: Teiid
Issue Type: Quality Risk
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.10
The optimizer will select plans with cross joins (particularly with a parent dependent join) when the join is to be processed in Teiid and the cardinality of both sides of the join are unknown.
We should prefer non cross join plans in these scenarios.
