Could you explain what is meant by the type of dissemination in the context of events or messages?

The distribution type in the context of events or messages determines how the event is transmitted and processed by subscribers. Main types of distribution:

• Synchronous — the event is processed immediately, invoking handlers in the same thread.
• Asynchronous — handlers are invoked later, for example, via a message queue or a separate thread.
• Broadcast — the event is sent to all subscribers.
• Unicast — the event is directed to a specific recipient.

Choosing the distribution type affects the application's performance and architecture.
