Steven Hawkins commented on TEIID-3898:
---------------------------------------

> Noticed this neat trick in the JPA translator to only push down joins on foreign keys.

Yes, several of the hierarchical sources have that requirement.  See salesforce also, which has to produce valid SOQL queries.

> Maybe as predicate functions in the where clause?

We have similar logic in the Modeshape translator, which has JCR constructs that are effectively predicates, but need special handling in the translator.

> Add OrientDB translator

> My organization has high-performance analytics on OrientDB graph databases.  We use Teiid for centralized governance, access, etc.  It would be beneficial to us if Teiid could translate to the SQL-like OrientDb syntax.  Because there are many SQL-like syntax components of OrientDB's REST endpoints this should be fairly straightforward.
> The OrientDB site is http://orientdb.com/.  It's Apache 2 licensed, has a stable and mature community, has multiple releases, and provides multiple access methods (jdbc, odbc, REST).  Work on the translator should not be wasted effort.
> I can assist with testing if it would be helpful and if the translator is started I can assist in dev.
