What are the differences between pub-sub and request-response communication models?

What are the differences between pub-sub and request-response communication models?

The pub-sub model allows for asynchronous communication where publishers send messages without knowing who will receive them, while request-response is synchronous, requiring a direct response to each request.

Can you give me an example of when to use pub-sub?

Sure! Pub-sub is great for scenarios like live sports updates, where multiple subscribers want real-time information without polling the server.

And what about request-response? When is it more suitable?

Request-response is ideal for situations where immediate feedback is needed, like submitting a form and waiting for a confirmation.

Are there any drawbacks to using pub-sub?

Yes, pub-sub can lead to message loss if subscribers are not active when messages are sent, and it can be harder to debug due to its asynchronous nature.
