OIDC Integration

July 22, 2022 by Marcial Rosales
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 Authorization server compliant with OpenID Connect and OAuth 2.0 protocols. Furthermore, OAuth 2.0 authorization code grant becomes the default grant and implicit grant is no longer supported.

Required feature flags in RabbitMQ 3.11.0

July 20, 2022 by Jean-Sébastien Pédron
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 are a mechanism to make breaking changes to RabbitMQ while still maintaining the compatibility between several versions of RabbitMQ. They usually come with code to migrate data structures in the internal schema database or on disk for instance.

RabbitMQ 3.11 Feature Preview: Super Streams

July 13, 2022 by Arnaud Cogoluègnes

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 an overview of super streams and the use cases they unlock. Read on to learn more, we value your feedback to make this feature the best it can be.

RabbitMQ 3.11 Feature Preview: Single Active Consumer for Streams

July 5, 2022 by Arnaud Cogoluègnes

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 more about single active consumer for streams and don’t hesitate to experiment with what is already available: try it, break it, tell us what you like and don’t like, what’s missing. Your feedback is essential to make this feature the best it can be.
