Steven Hawkins resolved TEIID-4943.
-----------------------------------
Resolution: Done
Changed the planning behavior to only push the copied criteria in specific circumstances,
rather than generally even when we are already under an access node. This mostly, but not
completely, addresses the referenced forum post. There are still circumstances involving
delayed pushdown, or greater transitivity (such as three tables all joined by the same
columns), that would still result in the copied predicate being pushed.
Allow translators to declare if copied criteria should be included

Key: TEIID-4943
URL:
https://issues.jboss.org/browse/TEIID-4943
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 10.0
When an inner join with a predicate that can be copied is pushed, we will still create
the copied criteria. In some situations, this over-constraining is not desirable. There
should be a capability to determine if this copying should take place.
