[jira] [Created] (OAK-4451) Implement a proper template cache

Michael Dürig created OAK-4451:
----------------------------------

             Summary: Implement a proper template cache
                 Key: OAK-4451
                 URL: https://issues.apache.org/jira/browse/OAK-4451
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: segment-tar
            Reporter: Michael Dürig
             Fix For: 1.6


The template cache is currently just a map per segment. This is problematic in various ways: 
* A segment needs to be in memory and probably loaded first only to read something from the cache. 
* No monitoring, instrumentation of the cache
* No control over memory consumption 

We should there for come up with a proper template cache implementation in the same way we have done for strings ({{StringCache}}) in OAK-3007. Analogously that cache should be owned by the {{CachingSegmentReader}}.
