✨This talk was recorded at RabbitMQ Summit 2023. If you're curious about our upcoming event, check https://rabbitmqsummit.com ✨ Nobody wants to lose a single message. When everything works fine, then all is easy. But what happens when things go wrong: the dreaded split brain, network partitions, losing disks. This is where the fun starts. In this talk we explore the technology powering RabbitMQ. We’ll scratch the surface of internode clustering, Mnesia and why we still need to know about them. New advances in RabbitMQ in recent years improved resiliency tremendously. We discuss how quorum queues and streams fit in and provide consistency and resiliency we always wanted. Understanding how the internals affect the operational experience can help us scale and avoid potential outages. A future proof design with the available features can be challenging but following some simple guidelines can take us a long way. Let's keep in touch!
