System Design Insight
Pub-Sub enables event-driven architectures where publishers broadcast messages to topics, and all subscribers to that topic receive the message. This pattern provides loose coupling, allowing publishers and subscribers to evolve independently. Unlike queues, messages are delivered toall subscribers, making it ideal for notifications, event sourcing, and real-time updates. Use pub-sub when you need one-to-many message distribution.
