Steven Hawkins commented on TEIID-2885:
---------------------------------------
dependentJoinPushdownThreshold has been removed for 8.11. That will give the optimizer
more flexibility in utilizing full pushdown. Also the hints will be updated to prevent
that if needed.
Allow dependent join pushdown to be chosen by the planner

Key: TEIID-2885
URL:
https://issues.jboss.org/browse/TEIID-2885
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.8, 8.7.1
As a follow on to TEIID-2249, the planner should be able to choose when to use full join
pushdown, rather than only relying upon a hint. One downside to this currently is that
there isn't a good way to do a back off to a different join processing (unless we
embedded an alternative plan) and so we may have to add failure logic if too many
independent values are retrieved.
