RabbitMQ र Kafka दुवै messaging systems हुन् तर मौलिक रूपमा फरक छन् — RabbitMQ एक traditional message broker हो (queues, flexible routing, messages consumed र removed), जबकि Kafka एक distributed event log हो (retained, replayable, high-throughput streaming)। तिनीहरू विभिन्न use cases को लागि उपयुक्त छन्।
मौलिक फरक
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
