Subject [jira] Commented: (JCR-2715) Improved join query performance
Date Fri, 15 Oct 2010 13:10:33 GMT

    [ https://issues.apache.org/jira/browse/JCR-2715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12921338#action_12921338

Serge Huber commented on JCR-2715:

If I understand this ticket properly, this doesn't only happen for join queries but for all
SQL-2 queries no ?

In the first solution, do you mean you intend to map the single selector queries along with
using BooleanQuery objects to map constraints directly to the underlying Lucene query ?

Anyway, I'd be willing to help anyway possible as this is become the biggest performance issue
we are seeing in testing Jackrabbit with non-trivial data sets and loads.
