Amazon MQ now provides support for RabbitMQ version 3.13 and Quorum queues on RabbitMQ 3.13. RabbitMQ version 3.13 includes several fixes and performance improvements to the previous versions of RabbitMQ supported by Amazon MQ. Starting from RabbitMQ 3.13, Amazon MQ will manage patch version upgrades for your brokers. All brokers on version 3.13 will be automatically upgraded to the latest compatible and secure patch version in your scheduled maintenance window.

Quorum queues are a replicated FIFO queue type offered by open-source RabbitMQ that uses the Raft consensus algorithm to maintain data consistency. Quorum queues are the replicated queue type recommended by open-source RabbitMQ maintainers. With quorum queues, developers can design highly available messaging systems with higher data consistency and fault tolerance. Quorum queues can detect network failures faster and recover more quickly, improving the resiliency of the message broker as a whole. Quorum queues also provide poison message handling which helps developers manage unprocessed messages more efficiently. Amazon MQ benchmarks show that quorum queues offer an increased throughput (up to 2 times higher) compared to classic mirrored queues on RabbitMQ brokers.

If you are running earlier versions of RabbitMQ, such as 3.8, 3.9, 3.10, 3.11 or 3.12, we strongly encourage you to upgrade to RabbitMQ 3.13. This can be accomplished with just a few clicks in the Amazon Web Services Management Console. Amazon MQ also supports quorum queues only on RabbitMQ 3.13 and above. You can easily get started with quorum queues by declaring a new queue with queue type as ‘quorum’. To learn more about using quorum queues, see the Amazon MQ developer guide and the Amazon MQ release notes. Amazon MQ for RabbitMQ will end support for RabbitMQ versions 3.8, 3.9 and 3.10 as indicated in the version support calendar. To learn more about upgrading to RabbitMQ 3.13, see Managing Amazon MQ for RabbitMQ engine versions in the Amazon MQ Developer Guide. This feature is available in all regions where Amazon MQ is available, including Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
