Why Kafka, and not other systems?

Kafka is chosen for its high performance, scalability, and reliability when working with real-time data streams. Unlike traditional message brokers, Kafka stores messages on disk and allows consumers to read them at different speeds, which is convenient for building complex systems with multiple subscribers.

Main advantages of Kafka:

• High throughput and low latency
• Horizontal scaling through topic partitioning
• Delivery guarantees (at-least-once, exactly-once)
• Support for message history storage for re-reading

This makes Kafka a preferred choice for systems with large data streams, analytics, and microservices architecture.
