Pub/Sub

Pub/Sub (Publish/Subscribe) is a communication pattern where message senders (publishers) don't send messages directly to receivers (subscribers). Instead, publishers send messages to a central system called a message broker, which then distributes those messages to all interested subscribers based on their subscriptions. This setup allows for decoupled, scalable communication, enabling multiple systems or components to exchange information efficiently without direct dependencies. It is commonly used in messaging systems, event-driven architectures, and real-time data processing to ensure timely and organized data sharing.
