Publishsubscribe

+**Publish-subscribe** is a [messaging pattern](/wiki/Messaging_Pattern) where senders (publishers) broadcast messages to topics, rather than directly to specific receivers. Subscribers express interest in these topics, receiving all relevant messages without needing to know the publishers. This enables [asynchronous](/wiki/Asynchronous) and decoupled communication, enhancing system flexibility.
