A RabbitMQ quorum queue deletes each message once it is acknowledged and fsyncs before accepting it; a stream keeps it for rereading. On RabbitMQ 4.3.6, with 1 KB messages, the quorum queue moved 45,156 msg/s and the stream, over its own protocol, 281,330 msg/s, using 9 KB of memory per million messages against 20.5 MB.
Redpanda promises Kafka-protocol compatibility without the JVM, without ZooKeeper, and with a thread-per-core architecture. By 2025 there are already serious production deployments. It is worth understanding where the switch pays off and where it does not.
To remove ZooKeeper from Kafka you have to go through 3.9. I migrated a three-broker Kafka 3.9.2 ZooKeeper cluster to KRaft in Docker and then upgraded it to Kafka 4.4.0: five phases with rolling restarts, the config and commands for each one, and all 100,000 messages intact at the end.
Kafka gets the headlines as the byword for modern messaging, but RabbitMQ remains the better choice for task queues with retries, asynchronous RPC, and pub/sub with complex routing. This guide compares both against NATS, walks through classic patterns and production mistakes, and helps you decide based on the actual use case rather than the trend.
