The UUID _generation_ is not a problem. (I it a bit slow, but scales well - no issue there). The UUID _lookup_ is not a problem either. The problem is indexing, because this is a unique index (wasted storage space, wasted CPU and latency). The issue is, in most cases there is no need for this UUID. So why index it. Sure, we could improve indexing (improve unique property indexes). But it would be easier to not index those nodes at all. I would not change nt:resource because of backward compatibility issues. Instead I would recommend not to use nt:resource. See SLING-6090. Regards, Thomas
