What is Kafka and how does it differ from RabbitMQ?

Kafka is a distributed data streaming platform focused on high throughput and scalability. It stores messages in topics and allows consumers to read them from the desired position.

RabbitMQ is a message broker implementing message queues with support for various protocols, aimed at reliable delivery and routing.

Main differences:

• Kafka stores messages longer and allows multiple reads, RabbitMQ deletes messages after delivery.
• Kafka is better suited for processing large data streams and analytics, RabbitMQ for traditional task queues and workload distribution.

Example: if you need to process logs in real-time and store them for analysis, Kafka is chosen. If you need to distribute tasks among workers, RabbitMQ is more convenient.
