Publish-Subscribe

Publish-Subscribe is a communication pattern where senders (publishers) send messages to a central system without knowing who will receive them. Receivers (subscribers) express interest in specific topics and receive only relevant messages. The system manages distribution, ensuring that subscribers get updates on topics they care about. This setup allows for flexible and scalable communication, making it ideal for systems like news feeds, notifications, or event-driven applications. Essentially, publishers share information, and subscribers listen to the topics they’re interested in, with the system handling the delivery details behind the scenes.
