Broadcasting Simple Messages
Practice publishing messages to channels and subscribing to receive them using the Redis CLI and client libraries.
What is Broadcasting?
In the world of Pub/Sub, broadcasting means sending a single message that can be received by many listeners at once.
Think of it like a radio station: the station broadcasts music, and anyone tuned to that frequency can hear it.
- One sender (publisher)
- Many receivers (subscribers)
- Decoupled communication
The Publisher's Role
A publisher is the entity that sends messages. It doesn't care who is listening or if anyone is listening at all.
Publishers simply send messages to a specific channel. Redis then takes care of delivering that message to all active subscribers of that channel.
