 Cheeper is configured so signing up new Authors is a synchronous operations. This mean that once the HTTP request made to the Cheeper API is finished, the Author will be in the database without having to perform any other action. As soon the API receives the request, the SignUpCommand is created and delegated to the Command Bus. The Command Bus will check the routing configurations and it will pass the Command to the SignUpCommandHandler that will perform all the actions required to sign up a new Author.

 The response to the HTTP request and the Authors in the database are not the only outcome generated. In RabbitMQ, there are store multiple events of type `NewAuthorSigned`. Those Domain Events are waiting to be handled. In order to do so, they will have to be consumed. Until not getting consumed, the Follower Counters Query will still return a 404 HTTP Status Code.
