TOPIC OVERVIEW

Redis/Pub-Sub

Let Redis instantly broadcast messages from publishers to every subscriber listening to a channel.

12 QuestionsIntermediateMedium Priority ~8 min read

Redis Pub/Sub provides a simple way for applications to send messages through channels. A publisher sends a message to a channel, and every currently connected subscriber listening to that channel receives it.

This is useful for real-time notifications, application events, and communication between processes. However, standard Pub/Sub does not store messages for disconnected subscribers, so it is not always the right choice when reliable message delivery is required.
