Publish/Subscribe (Pub/Sub) Pattern
The Publish/Subscribe (Pub/Sub) pattern is a messaging paradigm where senders (publishers) broadcast messages without needing to know who will receive them. Receivers (subscribers) declare interest in specific message types and only receive those relevant messages.
Key Points:
- Decoupling: Publishers and subscribers operate independently, allowing for more flexible development.
- Scalability: This pattern supports scalability by permitting numerous publishers and subscribers within the same system.
- Flexibility: Adaptable for dynamic systems where participants or conditions may frequently change.
