MongoDB::WriteConcern - Encapsulate and validate a write concern

Attributes

w
       Specifies the desired acknowledgement level. If not set, the server default will be used, which is
       usually "1".

   wtimeout
       Specifies how long to wait for the write concern to be satisfied (in milliseconds).  Defaults to 1000. If
       you set this to undef, it could block indefinitely (or until socket timeout is reached).

   j
       The j option confirms that the mongod instance has written the data to the on-disk journal.  Defaults to
       false.

       Note: specifying a write concern that set j to a true value may result in an error with a mongod or
       mongos running with --nojournal option now errors.
