What are the differences between Redis Streams and Pub/Sub?

What are the differences between Redis Streams and Pub/Sub?

Redis Streams and Pub/Sub are both messaging systems, but they serve different purposes. Pub/Sub is a simple messaging pattern where messages are sent to subscribers without storing them, while Streams allow for message persistence and more complex data structures.

Can you explain how message persistence works in Redis Streams?

In Redis Streams, messages are stored in a log-like structure, allowing consumers to read messages at their own pace. This means that even if a consumer is offline, they can retrieve messages later.

What are some use cases for Redis Streams?

Redis Streams are great for event sourcing, real-time analytics, and managing data flows in applications where message order and persistence are crucial.

Is there a performance difference between using Redis Streams and Pub/Sub?

Yes, Redis Streams can handle higher throughput due to their ability to persist messages and allow multiple consumers to read from the same stream, while Pub/Sub is more lightweight but can lose messages if subscribers are not active.
