[teiid-issues] [JBoss JIRA] (TEIID-4100) Full odata expand support

[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-4100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-4100.
-----------------------------------
    Resolution: Done


The initial work has been completed.

Follow on tasks:

- support level
- remove the isSameEntity logic - which is only needed for the $it construct
- create an rewrite optimization to turn a single expand into a left outer join, which will preserve the performance characteristics of the old logic

> To move TEIID-3039 we need to have xml document model style processing for expand support.  That is top down generation that supports arbitrary descendants - with targeted optimizations for projection minimization and dependent joins.
