What message brokers have you worked with? Explain how Kafka works.

I have worked with RabbitMQ, Apache Kafka, and ActiveMQ.

Apache Kafka is a distributed streaming platform that functions as a high-performance message broker.

How Kafka works:

• Messages are published to topics.
• Topics are divided into partitions for parallelism and scalability.
• Producers send messages to topics.
• Consumers read messages from topics, and they can be organized into groups for load balancing.
• Kafka stores messages on disk with long-term storage capabilities, allowing data to be re-read.

Kafka provides high throughput, fault tolerance, and scalability, making it popular for processing large streams of real-time data.
