Designing pub-sub

We have identified the requirements for our system. Let’s dive into designing the system.

Designing a pub-sub system

At a high level, the components involved in the design of the pub-sub system are:

• Broker: It is responsible for taking the message from the client and sending them to the receivers.

• Writer: It writes the message of the client.

• Reader: It reads the message for the client.

So the writer will push the messages to the broker. The broker will take those messages and push them to the readers.
