Learning how KAFKA works !!

I just completed a hands-on project to understand how microservices communicate asynchronously. What I built: 📍 Delivery Service: Acts as a Producer, sending real-time location updates. 📩 Apache Kafka: The middleman (Broker) that handles the data stream. 📥 Customer Service: The Consumer that listens and saves every update to an H2 Database. My biggest "Aha!" moment: Realizing that the Delivery Service doesn't need to wait for a database confirmation. It just drops the message in Kafka and moves on. This is how apps like Uber scale to millions of users!
