Name the three main differences between Kafka and RabbitMQ.

Message Model:

• Kafka uses a publish-subscribe model with message storage in topics, where messages are stored on disk and accessible for multiple consumers.
• RabbitMQ is based on message queues, where messages are delivered to consumers and removed from the queue after processing.

Message Storage and Delivery:

• Kafka stores messages for a long time, allowing re-reading of data and use for analytics.
• RabbitMQ focuses on instant delivery and deletes messages after acknowledgment.

Performance and Scalability:

• Kafka is optimized for high-performance processing of large data streams and scales horizontally.
• RabbitMQ is better suited for complex message routing and integration with various protocols but may lag behind Kafka in throughput under heavy loads.
