For some reason, many developers view RabbitMQ and Kafka as interchangeable. The goal of this post is to present both RabbitMQ and Kafka side-by-side.
- RabbitMQ is preferable when we need:
- Advanced and flexible routing rules.
- Message timing control (controlling either message expiry or message delay).
- Advanced fault handling capabilities, in cases when consumers are more likely to fail to process messages (either temporarily or permanently).
- Simpler consumer implementations.
- Kafka is preferable when we require:
- Strict message ordering.
- Message retention for extended periods, including the possibility of replaying past messages.
- The ability to reach a high scale when traditional solutions do not suffice.
