             Summary: Commit does not ensure w:majority
                 Key: OAK-2592
                 URL: https://issues.apache.org/jira/browse/OAK-2592
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core, mongomk
            Reporter: Marcel Reutegger
            Assignee: Marcel Reutegger
             Fix For: 1.4


The MongoDocumentStore uses {{findAndModify()}} to commit a transaction. This 
operation does not allow an application specified write concern and always uses 
the MongoDB default write concern {{Acknowledged}}. This means a commit may not 
make it to a majority of a replica set when the primary fails. From a 
MongoDocumentStore perspective it may appear as if a write was successful and 
later reverted. See also the test in OAK-1641.

To fix this, we'd probably have to change the MongoDocumentStore to avoid 
{{findAndModify()}} and use {{update()}} instead.
