Which message broker would you prefer to use — Kafka or RabbitMQ?

The choice between Kafka and RabbitMQ depends on the specific project requirements. Kafka is better suited for processing large data streams with high throughput and message storage (event logs). It focuses on scalability and resilience, suitable for analytics, streaming processing, and event-driven systems. RabbitMQ is a classic message broker supporting various exchange models (queues, topics), suitable for guaranteed delivery, complex routing, and service integration. If high performance and large data volume processing are needed, Kafka is preferable. For flexible routing and reliable delivery, RabbitMQ is better. Example of Kafka usage in Go with the sarama library is provided in the original text.
