> Key: OAK-2681
> URL: https://issues.apache.org/jira/browse/OAK-2681
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core, mongomk
> Reporter: Marcel Reutegger
> Assignee: Marcel Reutegger
> Labels: concurrency, technical_debt
> Fix For: 1.3.1
>
>
> A lease update of the DocumentNodeStore on MongoDB will acquire a lock in
> MongoDocumentStore to perform the changes. The locking is only necessary for
> changes in the 'nodes' collection, because only those documents are cached
> and the locking makes sure the cache is consistent. The MongoDocumentStore
> must be changed to only acquire a lock when changes are done in the 'nodes'
> collection.
