PICK A TOPIC
[1/3]
Apache Kafka
Pick this when…
- · Event streaming + replay needed
- · Heavy analytics pipelines (> 100k msg/s)
- · Log-centric architecture
- · Multi-consumer independent cursors
RabbitMQ / NATS
Pick that when…
- · RabbitMQ: traditional work queues with routing
- · RabbitMQ: priority queues + delayed delivery
- · NATS: sub-10ms fan-out messaging
- · NATS: service-to-service in Kubernetes
FACTORS TO WEIGH
[2/3]
| Factors to weigh | Apache Kafka | RabbitMQ / NATS |
|---|---|---|
| Throughput | Millions/s | RabbitMQ ~50k/s, NATS millions/s |
| Latency | ~5-10ms | RabbitMQ ~3-5ms, NATS <1ms |
| Replay | Native (infinite retention) | Not native |
| Routing patterns | Topics + partitions | RabbitMQ exchanges + bindings, NATS subjects |
| Ops complexity | High (ZK / KRaft, storage) | RabbitMQ medium, NATS low |
| Cloud-managed | Confluent, MSK, Upstash | CloudAMQP, Synadia |
| We recommend | Event streams + analytics | RabbitMQ for work queues, NATS for low-latency |
