What are some use cases for the publish-subscribe pattern?

The publish-subscribe pattern is widely used in various applications. For instance, it's common in messaging systems, where publishers send messages to multiple subscribers without knowing who they are.

Can you give me an example of a messaging system that uses this pattern?

Sure! An example is a news application where publishers post articles, and subscribers receive updates based on their interests.

Are there any other domains where this pattern is useful?

Yes, it's also used in event-driven architectures, IoT systems, and real-time data streaming, allowing for efficient data distribution.

How does it compare to the request-response pattern?

In contrast to request-response, where a client requests data from a server, publish-subscribe allows for asynchronous communication, enabling more scalable and decoupled systems.
