Subject [jira] [Resolved] (OAK-3066) Persistent cache for previous documents
Date Fri, 29 Jan 2016 03:44:39 GMT

     [ https://issues.apache.org/jira/browse/OAK-3066?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vikas Saurabh resolved OAK-3066.
--------------------------------
       Resolution: Fixed
    Fix Version/s:     (was: 1.4)

Committed to trunk at [r1727470|http://svn.apache.org/r1727470]. The test just verifies stats
across the 2 types of cache (prevDocsCache and nodesCache). I couldn't figure a way to verify
if prevDocsCache gets backed by persistent cache if one is configured (ideas?).
Mem cache percentage for prevDocsCache is set to 4% and would cut into document cache's share.

> Previous (aka split) documents contain old revisions and are immutable documents. Those
documents should go into the persistent cache to reduce calls to the underlying DocumentStore.
