[teiid-issues] [JBoss JIRA] (TEIID-5895) Create common mongodb logic

[Steven Hawkins (Jira)]

    [ https://issues.redhat.com/browse/TEIID-5895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13998428#comment-13998428 ] 

Steven Hawkins commented on TEIID-5895:
---------------------------------------

It appears that the join logic is quite specialized to the embedded doc case, so the only issue I see with the mongo join logic is around DBRef construct.  The issues are:

* the lookup is based upon name name, which does not account for conflicts - TEIID-5876
* it does not account for exclusions or other reasons why a collection may not be present and create a dangling fk - which is already present in the metadata tests
* if an fk is created, it will allow a join to be pushed down, which is not expected

based upon the above issues, I'll simply remove the creation of the fk.

> Similar to the refactoring of infinispan connectivity, the logic should be shared between teiid and teiid spring boot.  As well as a review of similar potential issues with the join filtering and TEIID-5876
