Regarding brokers — how did you use Kafka and RabbitMQ? Why two?

The project used both brokers — Kafka and RabbitMQ — for different reasons:

• Kafka was used for processing large data streams with high throughput and guaranteed message delivery. For example, for logging, analytics, and event processing, where scalability and fault tolerance are important.

• RabbitMQ was used for tasks with more complex message routing, supporting various queue types and delivery confirmation scenarios. It is well-suited for microservice architecture with asynchronous interaction and task processing.

Using two brokers allowed for optimal load distribution and selecting the right tool for specific requirements. Kafka — for streaming and storing events, RabbitMQ — for task management and communication between services with flexible routing.
