Subject [jira] Created: (JCR-190) Caching in QueryHandler does not scale well
Date Wed, 17 Aug 2005 12:17:54 GMT
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
