DESCRIPTION

       Sets the default read preferences to use for operations on collection not specifying a read preference.

       The  global default is MONGOC_READ_PRIMARY: if the client is connected to a replica set it reads from the
       primary, otherwise it reads from the current MongoDB server.

       Please see the MongoDB website for a description of Read Preferences.
