[teiid-issues] [JBoss JIRA] (TEIID-1540) Add the ability to delegate one shot dependent joins to the translators

[Steven Hawkins (Resolved) (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-1540?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-1540.
-----------------------------------

    Resolution: Done


Added pushdown support for dependent joins and added a description of how to use this feature in the developers guide.

This is a relatively advanced use case and may need refinement, such as letting the engine handle dependent joins in specific circumstances (such as via a hint parameter with TEIID-1544.

> Using a memory safe iterator, like with bulk handling, we should be able to push dependent joins to the translator to perform specialized source specific one-shot join handling.
> With the other dependent join improvements this should hopefully be needed only in the most extreme cases.
