allows for some interesting transitive relationships to be discovered and addresses the
case given in the description.

Key: TEIID-1338
URL:
https://issues.jboss.org/browse/TEIID-1338
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 7.1
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 7.3
A situation such as
from a, b, c where a.x = b.x and a.x = c.x
such that b and c are on a different source than a, it would be good to also use
transitive condition b.x = c.x.
