Marcel Reutegger resolved JCR-190:
----------------------------------
Resolution: Fixed
Caching is now less memory consuming.
- Caching the hierarchy relation between indexed nodes needs approximately 25
bytes per node.
- UUID to lucene document number mapping is cached with a LRU algorithm. The
default cache size is set to 1000 entries.
Implemented in svn revision: 234492
> Caching in QueryHandler does not scale well

> Fix For: 1.0
>
> Caching in class CachingIndexReader uses too much memory. It uses around 500
> bytes per node and does not use any strategy to limit the cache.
> This improvement covers two goals:
> - lower per-node memory cost for caching
> - implement a caching strategy using e.g LRU algorithm
