What are the main differences between Redis Pub/Sub and a message queue?
Redis Pub/Sub is a messaging pattern where messages are broadcast to multiple subscribers, while a message queue stores messages for processing by consumers.
When should I use Pub/Sub instead of a queue?
Use Pub/Sub when you need real-time message broadcasting to multiple subscribers. Use a queue for reliable message processing.
Can you give an example of a use case for each?
Sure! Use Pub/Sub for live sports updates, and a queue for processing orders in an e-commerce application.
What are the performance implications of using one over the other?
Pub/Sub can be faster for broadcasting, but queues provide better reliability and message delivery guarantees.
