RabbitMQ और Kafka दोनों messaging systems हैं लेकिन मौलिक रूप से भिन्न हैं — RabbitMQ एक traditional message broker है (queues, flexible routing, messages consume होकर हट जाते हैं), जबकि Kafka एक distributed event log है (retained, replayable, high-throughput streaming)। वे विभिन्न use cases के लिए उपयुक्त हैं।
मौलिक अंतर
RABBITMQ → a message BROKER (smart broker, simple consumer):
→ messages ROUTED via exchanges, CONSUMED and removed (transient)
→ rich ROUTING (exchange types); per-message handling; push-based
→ for: task queues, complex routing, request/reply, traditional messaging
KAFKA → a distributed event LOG (simple broker, smart consumer):
→ events RETAINED (not removed on consume), replayable; partition-based
→ very high throughput; multiple consumers read the same data; pull-based
→ for: event streaming, high-volume data, pipelines, retention/replay
