This Month in RabbitMQ, April 2020 Recap

A Webinar on Quorum Queues

Before we start with RabbitMQ project and community updates from April, we have a webinar to announce! Jack Vanlightly, a RabbitMQ core team member, will present on High Availability and Data Safety in Messaging on June 11th, 2020.

In this webinar, Jack Vanlightly will explain quorum queues, a new replicated queue type in RabbitMQ. Quorum queues were introduced in RabbitMQ 3.8 with a focus on data safety and efficient, predictable recovery from node failures. Jack will cover and contrast the design of quorum and classic mirrored queues.

After this webinar, you'll understand:

• Why quorum queues offer better data safety than mirrored queues
• How and why server resource usage changes when switching to quorum queues from mirrored queues
• Some best practices when using quorum queues
