-----------------------------------

             Summary: Cache in CachingBlobStore might grow beyond configured limit
                 Key: OAK-6303
                 URL: https://issues.apache.org/jira/browse/OAK-6303
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: blob, core
            Reporter: Julian Reschke
            Assignee: Thomas Mueller
         Attachments: OAK-6303-test.diff

It appears that depending on actual cache entry sizes, the {{CacheLIRS}} might grow beyond
the configured limit.

For {{RDBBlobStore}}, the limit is currently configured to 16MB, yet storing random 2M entries
appears to fill the cache with 64MB of data (according to it's own stats).

The attached test case reproduces this.
