Kafka for Developers - Data Contracts Using Schema Registry - Update the Code to Interact with Maven Local Repository -

This lecture focuses on Maven users, detailing the process of versioning a schemas module. It covers changing the version to 1.0, publishing it to the Maven local repository, and updating consuming applications to reference the new version. The lecture also addresses troubleshooting common issues and ensuring the consumer can read messages from the producer. The goal is to manage version compatibility in Kafka producer-consumer setups.
