Pub/Sub
A messaging pattern where publishers send messages to topics that subscribers receive.
Why it matters
- Fully decouples publishers from subscribers
- Enables broadcasting to multiple consumers
- Scales well for event-driven architectures
When to use
- When multiple services need to react to the same event
- For real-time notifications and updates
- When building event-driven systems
Common mistakes
- Not handling subscriber failures gracefully
- Creating too many fine-grained topics
- Not considering message ordering requirements
