We intend to release RabbitMQ 3.11.0 on 5 September 2022. While we have been testing it internally for some time, with production-like workloads, we need your help to check that it is as stable and reliable as we believe it is. This is the timeline that we have to work…
Team RabbitMQ and community members have recently identified a curious scenario where a freshly started node could consume a surprisingly high amount of memory, say, 1.5 GiB or so. We'd like to share our findings with the community and explain what short term and longer term workarounds are available. Some…
Quorum Queues are a superior replacement for Classic Mirrored Queues that were introduced in RabbitMQ version 3.8. And there are two complementary reasons why you would need to migrate. First of all, Classic Mirrored Queues were deprecated in 3.9, with a formal announcement posted on August 21, 2021. They will…
RabbitMQ's core protocol has been AMQP 0.9.1. To support MQTT, STOMP, and AMQP 1.0, the broker transparently proxies via its core protocol. While this is a simple way to extend RabbitMQ with support for more messaging protocols, it degrades scalability and performance. In the last 9 months, we re-wrote the…
RabbitMQ now has an official Discord server started by the core team. If you prefer Discord to Slack, feel free to join it and discuss all things RabbitMQ! Introducing RabbitMQ Community Discord Server Thanks to Gavin Roy, the RabbitMQ community has had a place to communicate, help each other and…
RabbitMQ 3.12 will be released soon with many new features and improvements. This blog post focuses on the the performance-related differences. The most important change is that the lazy mode for classic queues is now the standard behavior (more on this below). The new implementation should be even more memory…
Native MQTT released in RabbitMQ 3.12 has delivered substantial scalability and performance improvements for IoT use cases. RabbitMQ 3.13 will support MQTT 5.0 and will therefore be the next big step in our journey to make RabbitMQ one of the leading MQTT brokers. This blog post explains how the new…
Stream filtering is a new feature in RabbitMQ 3.13. It allows to save bandwidth between the broker and consuming applications when those applications need only a subset of the messages of a stream. Keep reading to find out how stream filtering works and see it in action. Concepts of Stream…
A previous post gave an introduction to stream filtering, a new and exciting feature in RabbitMQ 3.13. In this post we cover the internals of stream filtering. Knowing the design and implementation will help you to configure and use stream filtering in the most optimal way for your use cases.…
We have been working for several weeks on a new website for RabbitMQ. We plan to release this significant upgrade shortly after RabbitMQ 3.13.0 is released! At this point, we would love you to visit the new website and tell us what you think :-) In this blog post, I…
