Client. Message bus

Here's a description of message bus from Enterprise Integration Patterns

A Message Bus is a combination of a common data model, a common command set, and a messaging infrastructure to allow different systems to communicate through a shared set of interfaces.

If all your applications built on top of Enqueue Client you have to only make sure they send message to a shared topic. The rest is done under the hood.

If you'd like to connect another application (written on Python for example ) you have to follow these rules:

• An application defines its own queue that is connected to the topic as fanout.
• A message sent to message bus topic must have a header enqueue.topic_name.
• Once a message is received it could be routed internally. enqueue.topic_name header could be used for that.
