Welcome to Hive, @shamimalmamun! Your payment.completed example makes service decoupling easy to follow, and I like that you’re digging into idempotency and safe offset commits alongside Kafka’s core concepts. InLeo Threads (inleo.io) could be a useful place to share bite-sized lessons from your Node.js and NestJS experiments between longer posts. Are you planning to build a small payment-and-notification demo to test retries and duplicate event handling?
