>
> 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.
