The OpenTelemetry project is an Observability framework and toolkit designed to create and manage telemetry data such as traces, metrics, and logs. It is gaining widespread adoption due to its consistent specification between signals and promise to reduce vendor lock-in which is something that we’re excited about. Looking back at…
RabbitMQ 3.10 was released on the 3rd of May 2022, with many new features and improvements. This blog post gives an overview of the performance improvements in that release. Long story short, you can expect higher throughput, lower latency and faster node startups, especially with large definitions files imported on…
Recent Erlang/OTP versions ship with Linux perf support. This blog post provides step by step instructions on how you can create CPU and memory flame graphs in RabbitMQ to quickly and accurately detect performance bottlenecks. We also provide examples of how flame graphs have helped us to increase message throughput…
RabbitMQ 3.11 will bring a noteworthy feature to streams: single active consumer. Single active consumer provides exclusive consumption and consumption continuity on a stream. It is also critical to get the most out of super streams, our solution for partitioning, that provide scalability for streams. Read on to find out…
RabbitMQ 3.11 will bring a feature with one of the coolest names in its history: super streams. Super streams are a way to scale out by partitioning a large stream into smaller streams. They integrate with single active consumer to preserve message order within a partition. This blog post gives…
RabbitMQ 3.11.0 will make all feature flags introduced during the life of RabbitMQ 3.8.x required. People who initially created clusters using RabbitMQ 3.8.9 or older should enable all feature flags before upgrading to RabbitMQ 3.11! If the feature flags are not enabled, RabbitMQ 3.11.0+ will refuse to start. Feature flags…
Today when we use the rabbitmq-management with the rabbitmq_auth_backend_oauth2 plugin, the only supported Authorization server is UAA, making it difficult to connect to other OAuth 2.0 servers. Additionally, rabbitmq-management plugin uses the OAuth 2.0 implicit flow which is no longer recommended for security reasons. RabbitMQ 3.11 will support practically any…
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…
