Redis Pub/Sub (Publish/Subscribe)
Redis Pub/Sub is a messaging paradigm where there are two main components: publishers and subscribers. Publishers send messages (events) to channels, and subscribers receive messages from the channels they are interested in. It’s a simple and efficient way to implement a publish/subscribe system for real-time communication within an application.
Differences:
- Channels: Pub/Sub relies on channels. Publishers send messages to specific channels, and subscribers listen to one or more channels they are interested in.
- Message Delivery: In Pub/Sub, messages are sent to all subscribers of a channel (broadcasting), and subscribers don’t typically receive missed messages if they weren’t listening when a message was published.
Difference between Redis Pub/sub vs Redis streams
Redis Pub/Sub (Publish/Subscribe) and Redis Streams are both features of the Redis database that enable real-time messaging and event-driven communication, but they have distinct use cases and characteristics.
