Subject [jira] Commented: (JCR-2715) Improved join query performance
Date Mon, 06 Dec 2010 07:28:12 GMT

    [ https://issues.apache.org/jira/browse/JCR-2715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12967111#action_12967111

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

Hello Jukka, 

Thanks for clarifying this. But it seems to me that a lot of developers will generate such
queries. I'll continue on the other ticket anyway, so that we can close this one.

Best regards,
  Serge Huber.

much any non-trivial data set.
