]
Steven Hawkins resolved TEIID-5346.
-----------------------------------
Resolution: Done
Updated the logic to better propagate ndv. Also added logic dealing with preventing the
creation of unnecessary dependent joins with copy criteria - which were the majority of
the test case changes.
Improve costing of literals even with unknown values
----------------------------------------------------
Key: TEIID-5346
URL: https://issues.jboss.org/browse/TEIID-5346
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 11.0
In the nodes above a projected literal if there are unknown cardinalities will become ndv
unknown - rather than the expected ndv/nnv.
