             Summary: Improve the document cache invalidation logic to selectivly ivalidate doc
                 Key: OAK-1156
                 URL: https://issues.apache.org/jira/browse/OAK-1156
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: mongomk
            Reporter: Chetan Mehrotra
            Assignee: Chetan Mehrotra


Currently the Background Read operation invalidates the complete cache in {{MongoNodeStore}} upon detecting external change. Instead of that it should check for which cached documents are stale and only invalidate them. 

It can make use of {{_lastRev}} to check if nodes within a subtree have changed or not.
