What are the differences between pub-sub and other messaging patterns?

Pub-sub is a messaging pattern where publishers send messages without knowing who will receive them, while other patterns like point-to-point require a direct connection between sender and receiver.

Can you explain how pub-sub works in real-time applications?

In real-time applications, pub-sub allows multiple subscribers to receive updates simultaneously when a publisher sends a message, making it efficient for broadcasting information.

What are some use cases for the pub-sub pattern?

Common use cases include chat applications, live sports updates, and stock market feeds, where timely information is crucial.

How does pub-sub compare to message queues?

Unlike message queues, which store messages until they are processed by a single consumer, pub-sub delivers messages to all subscribers instantly, promoting a more dynamic interaction.
