Pub/Sub: A Comprehensive Guide to Asynchronous Messaging
At a high level, Publish-Subscribe, commonly known as Pub/Sub, is a messaging pattern where senders of messages, called publishers, do not send messages directly to specific receivers, called subscribers. Instead, publishers categorize published messages into classes, without knowledge of what, if any, subscribers there might be. Similarly, subscribers express interest in one or more classes and only receive messages that are of interest, without knowledge of what, if any, publishers there are. This decoupling of publishers and subscribers is a core tenet of the Pub/Sub model, enabling greater scalability and flexibility in distributed systems. This pattern is fundamental to building modern, resilient, and scalable applications that can handle a high volume of messages and events.
