Let us consider a more complex Bus setup in order to understand the capabilities of the different parts of the infrastructure:

What are we expressing here?

  • Publishing is configured

  • If a message of type Transport is published, use the Sequential publisher
  • If a message type ends with “Request” in its name, publish a message of type Transport as constructed and use the non blocking publisher for the Request message.
  • If a message type ends with “Response” in its name, publish it in the parallel blocking fashion, then an instance of type Transport as shown.* Subscriptions are configured

This is an example where you perform Requests with messages that may be long running: They are published and the UI would have to wait until a “Response” becomes available. The Transport-messages mark those cycles such that a UI can use them in a general form to provide feedback to the user that something is happening.
