    Description

      When talking with server 3.4 or greater (maxWireVersion >=5), writeConcern is a supported option for all commands that write.
      The following methods and helpers should be updated to automatically pass writeConcern when maxWireVersion >= 5:

      Methods:

      • Collection.__create

      Helpers:

      • MongoClient.drop_database
      • Database.drop_collection
      • Collection.aggregate (when using $out)
      • Collection.create_indexes
      • Collection.create_index
      • Collection.ensure_index
      • Collection.drop_indexes
      • Collection.drop_index
      • Collection.map_reduce (when using $out)
      • Collection.reindex
      • Collection.rename

      Note:
      When the writeConcern on a command that writes fails, the resulting document still comes back with ok: 1. To check for write concern and raise the appropriate error, we need to check the result document for a writeConcernError field.
