How do pub-sub and request-response patterns differ?
An example of an AI chatbot conversation about comparing pub-sub and request-response patterns.
How do pub-sub and request-response patterns differ?
The pub-sub pattern 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 each pattern?
Sure! In a request-response pattern, a client might request data from a server and wait for a reply. In pub-sub, a weather station (publisher) sends updates to all subscribers (like apps) without knowing who they are.
What are the advantages of using pub-sub?
Pub-sub allows for scalability and decouples the components, making it easier to add or remove subscribers without affecting publishers.
Are there any downsides to using pub-sub?
Yes, pub-sub can introduce complexity in message delivery and may lead to challenges in ensuring message order and reliability.
