Publish And Subscribe Integration

Publish and subscribe integration is a sophisticated messaging pattern used in distributed systems to enable decoupled, asynchronous communication. Publishers send messages to topics, which act as intermediaries, and subscribers receive messages from these topics based on their subscriptions. This pattern supports real-time event notifications, dynamic scaling, and independent development of system components. Advanced implementations often include features like message filtering, fanout (sending a message to multiple subscribers), and durable messaging to ensure reliability and fault tolerance.
