[jira] [Created] (OAK-1406) Background operations block writes

Marcel Reutegger created OAK-1406:
-------------------------------------

             Summary: Background operations block writes
                 Key: OAK-1406
                 URL: https://issues.apache.org/jira/browse/OAK-1406
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core, mongomk
    Affects Versions: 0.16
            Reporter: Marcel Reutegger
            Assignee: Marcel Reutegger


The background operations thread in DocumentNodeStore blocks writes to ensure a correct sequence of revisions introduced by local and external commits. Within this synchronization block the thread also invalidates caches.  OAK-1156 introduced a selective cache invalidation logic, which only invalidates documents that changed, but also comes with additional cost because it will make calls to MongoDB.
