broker topology vs mediator topology

Comment

The mediator topology is commonly used when you need to orchestrate multiple steps within an event through a central mediator, whereas the broker topology is used when you want to chain events and responses together directly without the need for a mediator.

There are four main types of architecture components within the mediator topology: event queues, an event mediator, event channels, and event processors. 
The event flow starts with a client sending an event to an event queue, which is used to transport the event to the event mediator. 
The event mediator receives the initial event and orchestrates that event by sending additional asynchronous events to event channels to execute each step of the process. 
Event process‐ ors, which listen on the event channels, receive the event from the event mediator and execute specific business logic to process the event.
