Subscribers can follow multiple channels, enabling concurrent reception of messages from various sources. When a publisher disseminates a message to a channel, Redis delivers it to all connected subscribers of that channel. Channels are string-based identifiers that serve as communication conduits. In this model, a Redis client can act as both a publisher, sending messages to channels, and a subscriber, receiving messages from those channels. Redis Pub/Sub (Publish/Subscribe) is a messaging pattern that facilitates the broadcasting of messages to multiple subscribers.
