Ard Schrijvers commented on JCR-1337:
-------------------------------------
When per-document payloads and unique doc ids are implemented in lucene, we
might be able to optimize the hierarchical cache, because we might base it on
uid instead of the current doc id (based on uid, we might keep the hierarchical
cache intact for ever, even after segment merges and pre-warming / caching will
be trivial)
See dev list lucene mail about the subject:
