Have you worked with Kafka? Was another message broker used?

Yes, I have worked with Kafka. It is a distributed messaging streaming platform known for high performance and scalability. Kafka is often used for processing large streams of real-time data.

Besides Kafka, I have worked with other message brokers, such as:

• RabbitMQ — supports various protocols, suitable for queues with acknowledgments and routing.
• ActiveMQ — a classic broker supporting JMS, suitable for integration into Java applications.
• Amazon SQS — a cloud-based message queue service, managed and scalable.

Each broker has its own features and use cases. Kafka is well-suited for processing large data streams and storing messages with the ability to re-read, whereas RabbitMQ is convenient for traditional task queues and complex routing.
