[teiid-issues] [JBoss JIRA] (TEIID-979) Add pushdown support for sql/xml functions

[Tom Arnold (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13295143#comment-13295143 ] 

Tom Arnold commented on TEIID-979:
----------------------------------

>  If Teiid simply generated a plan that pushed a join rather than individually processing the subqueries, would that be acceptable?

Yes I think that would be helpful. Anything is better than N-many queries.

> Otherwise can you create a sub-task with the specific sql/xml constructs you need to be pushed?

I will write a new JIRA for this. Do you have an idea of what work would be involved? I can probably work on it if it doesn't fit on your roadmap.

Thanks!
