[Thanks a lot for your valuable feedback. I implemented socket.io as this is a personal project. can you please shed some light on how it's done in production? It would be really great if you could suggest some resources for better understanding.](https://hashnode.com/posts/building-real-time-chat-functionality-with-socketio-in-nodejs/658f261ed4abdc4aad882401/comment/6591b639bb9e53e89c95661a#reply-6591c6febb9e53e89c95f55f)

[Hi Rahul. I haven't used Kafka that much but from what I have understood so far is that Redis Pub/Sub and Kafka differ in terms of data persistence, message ordering, consumer model etc. While Kafka is pull-based, Redis Pub/Sub is push-based, delivering messages to subscribers as soon as they are published.](https://hashnode.com/posts/implementing-real-time-notifications-using-redis-pubsub/64737bc067dfaf4a8924ba46/comment/64742f34c9e56baaad57ff86#reply-64750e95780403b5073eafe1)
