[jira] [Created] (OAK-3723) Provide a pure read only mode for DocumentNodeStore

Chetan Mehrotra created OAK-3723:
------------------------------------

             Summary: Provide a pure read only mode for DocumentNodeStore
                 Key: OAK-3723
                 URL: https://issues.apache.org/jira/browse/OAK-3723
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: documentmk
            Reporter: Chetan Mehrotra
             Fix For: 1.4


Currently whenever an instance of DocumentNodeStore gets created it would make an entry to cluster collection and start the background read and write operations. Would also configured a last rev fixer etc

For safer tooling it would be required to have a mode where DocumentNodeStore can be configured to run only in a readOnly mode. In this mode
* No entry to be made in cluster collection
* No background write task scheduled
* No last rev recovery enabled
* In addition an option to also forcefully disable any explicit writes 

This would allows the user a confidence that any tooling (oak-run) based would not leave any sort of side effect on the running system
