In Hydra on NodeJS, serviceName is used in the Redis key expression and this allows any service to participate in the working of a queue. In HydraPy I felt that perhaps that decision in Node might have been a bad idea so I wanted to force that only queue owners can process messages. Granted you're correct that the service_name is the HydraPy get_queue_message function isn't being currently used in this early iteration. I think we continue to follow the approach in Hydra for Node by allowing the microservice implementor to decide how queues will be processed. So that would mean a PR to use service_name in the Redis key as Hydra for Node does.

  /**
   * @name _getQueuedMessage
   * @summary retrieve a queued message
   * @param {string} serviceName who's queue might provide a message
   * @return {promise} promise - resolving to the message that was dequeued or a rejection.
   */
  _getQueuedMessage(serviceName) {
    return new Promise((resolve, reject) => {
      this.redisdb.rpoplpush(`${redisPreKey}:${serviceName}:mqrecieved`, `${redisPreKey}:${serviceName}:mqinprogress`, (err, data) => {
        if (err) {
          reject(err);
        } else {
          let msg = Utils.safeJSONParse(data);
          resolve(msg);
        }
      });
    });
  }
