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.

Serge Huber.
