Have you ever worked with Kafka?

Yes, I have worked with Apache Kafka in the context of test automation and quality assurance. Specifically, I wrote tests that checked the correctness of publishing and consuming messages in Kafka topics, as well as integration scenarios where Kafka acted as an intermediary between microservices.

For this, I used Kafka client libraries, for example, in Java or Python, to send test messages and verify their receipt. I also used Kafka monitoring and logging tools to analyze system behavior under load and during failures.
