Pub/Sub

Pub/Sub in Redis is a powerful messaging paradigm that allows for real-time communication between clients through a publish/subscribe model. In this system, publishers send messages to specific channels without knowing who, if anyone, will receive them. Subscribers, on the other hand, express interest in particular channels and receive messages published to those channels instantly. This decouples the message producers from the consumers, facilitating flexible and scalable communication. Key commands in this model include PUBLISH for sending messages, SUBSCRIBE for listening to channels, and UNSUBSCRIBE for stopping the reception of messages.
