Pub/Sub Messaging
Pub/Sub (Publish/Subscribe) messaging is an asynchronous communication pattern where senders (publishers) distribute messages to receivers (subscribers) without specifying individual recipients. Publishers categorize messages into topics or channels, and subscribers express interest in one or more topics to receive relevant messages. This decouples producers from consumers, enabling scalable and flexible event-driven architectures.
Developers should use Pub/Sub messaging for building distributed systems that require real-time data streaming, event-driven processing, or microservices communication, such as in IoT applications, financial trading platforms, or social media feeds. It's ideal when you need to handle high-throughput, low-latency message delivery across multiple consumers without tight coupling, improving system resilience and scalability.
