Steven Hawkins commented on TEIID-5346:
---------------------------------------
I have the changes ready for this. The only downside is that we are more aggressive in
creating dependent joins - which in testing scenarios don't appear to be necessary
much like the one created by TEIID-5345. I'll spend a little more time on this to see
if we can do more to prevent the unnecessary dependent joins.
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.
