Subject [jira] Commented: (JCR-2715) Improved join query performance
Date Tue, 19 Oct 2010 07:30:27 GMT

    [ https://issues.apache.org/jira/browse/JCR-2715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12922469#action_12922469

Serge Huber commented on JCR-2715:
----------------------------------

Hello Jukka, 

I see you have been committing quite a lot of changes yesterday. Thank you very much ! I have
been looking at the changes. Do you still have more to commit ? I have some trouble understanding
how it works currently, as there seems to be no references to the QueryEngine in the code.
I'm assuming you haven't "glued" it together yet, is that correct or that you will commit
this soon ? Did I miss something ? 

Best regards, 
  Serge Huber.

> Our current implementation of SQL2 join queries does not perform very well on pretty
much any non-trivial data set.
