Can you name the difference between Kafka and RabbitMQ?

Kafka and RabbitMQ are message exchange systems, but with different architectures and purposes:

• Kafka is a distributed data streaming platform focused on high throughput and message storage in topics with re-reading capabilities. It is well-suited for processing large data streams, analytics, and event-driven systems.

• RabbitMQ is a classic message broker implementing queues with delivery confirmation, routing, and support for various protocols (AMQP). It is oriented towards guaranteed delivery and complex message routing.

Main differences:

Characteristic	Kafka	RabbitMQ
Model	Publish/subscribe with log	Queues with confirmation
Message storage	Long-term (logs)	Short-term (queues)
Performance	Very high, scalable	Good, but lower than Kafka
Delivery guarantees	"At least once"	"Exactly once" (with confirmations)

The choice depends on the task: for stream processing and analytics, Kafka is better; for traditional queues with delivery guarantees, RabbitMQ.
