[jira] Created: (JCR-190) Caching in QueryHandler does not scale well
Caching in QueryHandler does not scale well
-------------------------------------------
Key: JCR-190
URL: http://issues.apache.org/jira/browse/JCR-190
Project: Jackrabbit
Type: Improvement
Components: query
Environment: svn revision: 233161
Reporter: Marcel Reutegger
Assigned to: Marcel Reutegger
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

[jira] Resolved: (JCR-190) Caching in QueryHandler does not scale well
Posted by "Marcel Reutegger (JIRA)" <ji...@apache.org>.

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.
