> Key: OAK-1295
> URL: https://issues.apache.org/jira/browse/OAK-1295
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core, mongomk
> Reporter: Marcel Reutegger
> Assignee: Chetan Mehrotra
> Fix For: 0.20
>
>
> The _lastRev fields are periodically written to MongoDB with a background
> thread.
> This means there may be missing _lastRev updates when an Oak instance crashes.
> There must be a recovery mechanism in place when an Oak instance starts up.
> MongoMK needs to read the most recent _lastRev for the local cluster id and
> get
> documents with a _modified timestamp at _lastRev or newer. These are
> candidates
> for missing _lastRev updates. The _lastRev must only be updated for committed
> non-branch changes.
