Introduction to Pub/Sub

Welcome to Redis Pub/Sub! Pub/Sub, short for Publish/Subscribe, is a messaging pattern where senders (publishers) don't directly send messages to specific receivers (subscribers).

Instead, messages are sent to an intermediary, called a channel or topic. Subscribers then listen to these channels to receive messages.

In the Pub/Sub model, a publisher is the entity that creates and sends messages. Publishers don't need to know who (or if anyone) is listening.

• They focus only on sending messages to a specific channel.
• This makes the system flexible and scalable.
