Idempotence is a mathematical requirement of particular operations where the operation can be applied multiple times without changing the result beyond the initial application. The main driver behind the idempotency requirement is often to handle duplicated messages. As developers and architects, we need to pay close attention to how we deal with our production data during new deployments to ensure we are not losing any data, duplicating messages, or introducing malformed data into our system. Furthermore, we need to figure out how to automate the process and add testing guarantees to prevent any potential human error.
In this session, you will learn about the idempotent Kafka Producer & Consumer architecture and how to automate the CI/CD process with open-source tools.
