RabbitMQ 4 has been out for some time by now, and we have covered some of the goodies it comes with, compared to its predecesor, RabbitMQ 3.13. Some examples are improved performance, Native AMQP 1.0, new Quorum Queue features, bringing closer feature parity with Classic Queues.

It's time to retire the myth that RabbitMQ stores messages in memory. While it was true in the early days of RabbitMQ, and an option for the last 10 years, modern RabbitMQ versions almost always write messages to disk right away. In this blog post we review how different queue types store messages but the short answer is: not in memory!

RabbitMQ 4.0 (currently in beta) includes new quorum queue features:

• message priorities
• consumer priorities combined with Single Active Consumer
• default delivery limit is now 20 (breaking change!)
• faster recovery of long queues
