Subject [jira] Commented: (JCR-2715) Improved join query performance
Date Wed, 20 Oct 2010 06:51:26 GMT

    [ https://issues.apache.org/jira/browse/JCR-2715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12922872#action_12922872

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

Thanks for all the work ! I've tested the QueryEngine and results do indeed seem to be faster,
although I had an issue I'm not sure is due to my code regarding reading results twice.

Also, concerning limits, do they currently work with sorting ? If I limit to 100 results,
will it be the sorted 100 first results ? Or is sorting done after limiting ?

Let me know how I can help,
Best regards,
  Serge Huber.

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