Welcome and introduction


Keynote: Erlang powered Rabbits

Lukas Larsson

Erlang is a programming language designed to make it easier to handle many parallel interactions. It was originally intended for usage in telecom, but has since spread to messaging, databases, fintech systems, and message brokers such as RabbitMQ. Join me as we explore what makes Erlang uniquely suited for solving the problems in these domains, and what RabbitMQ does to leverage its strengths.


Update from RabbitMQ team

Ed Byford & Howard Twine



What's New in RabbitMQ Streams?

Arnaud Cogoluègnes

RabbitMQ 3.9 introduced streams, a new log-type data structure. What is the state of RabbitMQ Streams after one year of existence? Feedback from users helped stabilize and optimize it. The ecosystem grew with new client libraries in several programming languages. But streams are far from feature-complete: super streams, to scale out publishing and consuming, and single active consumer, to handle consumer concurrency, are the two major features coming up. Join this session to find out about the present and future of RabbitMQ Streams!

Managing RabbitMQ Usage at Scale for Bloomberg’s Trading Systems

Andrew Cook

Learn how Bloomberg's Order Management Systems (OMS) leverage RabbitMQ! We'll talk about how we use RabbitMQ for OMS applications. As you can imagine, these systems require particularly complex topologies in order to satisfy critical service-level requirements related to performance, reliability, scalability, and client isolation. The evolution of our OMS topologies posed some common problems. As these systems grew and evolved, virtual hosts became bloated. Workflows that started as simple publisher/consumer pipelines required more steps inserted. Connection strings needed to be changed to adopt amqpprox – a proxy for the RabbitMQ brokers. To solve these and other challenges, we needed a system that could easily coordinate changes to the way large numbers of applications use RabbitMQ. We will share how we did this by developing a configuration system that drives our applications’ interactions with the broker, while maintaining the flexibility of a loosely-coupled system.

Write fast, reliable, and secure clients!

Carl Hörberg

The RabbitMQ website has over 70 clients listed, so there is naturally a vast array of client libraries. Among these, there are several great, unofficial clients developed by the RabbitMQ community, so what could go wrong? As we aim to deliver the best possible clients, we need to be sure to keep everything above-board and high quality. Carl Hörberg (CloudAMQP) has contributed to several client libraries lately, including the amqp-client for Crystal, the TypeScript client both for Node.js and browsers (using WebSocket), and the amqp-client for Ruby, where the new Ruby client is more than 4 times faster than other Ruby clients. In this presentation, Carl talks about how to write fast clients that are also reliable and secure. He also tells you why he decided to write some new libraries.

How to Safely and Reliably Upgrade Your RabbitMQ Cluster While Maintaining 100% Uptime

Stefan Moser

The RabbitMQ team releases new features, bug fixes and security patches at a blistering pace, but *you* have to upgrade your cluster to take advantage of all the awesome new value. Upgrading a RabbitMQ cluster can be a harrowing adventure full of pitfalls and danger lurking around every corner. But fear not, you are not alone! Based on the experience of keeping a large fleet of RabbitMQ clusters up-to-date and running the latest version of RabbitMQ, we’ll walk through all of the steps that you can take to safely, reliably and triumphantly upgrade your RabbitMQ cluster, all while maintaining 100% uptime!

An update on Khepri adoption in RabbitMQ

Michael Klishin & Diana Parra Corbacho

Khepri, RabbitMQ's next generation schema database, has evolved significantly from the last time it was covered at RabbitMQ Summit. So has RabbitMQ core team's understanding of where it can be adopted before RabbitMQ 4.0. In this talk we will cover the continued evolution of Khepri, what it has to offer to RabbitMQ users, and how soon they can expect Khepri to ship in a GA release.

How We Rabbit at AWeber

Gavin Roy

RabbitMQ is at the heart of AWeber's event-based distributed architecture, responsible for the delivery of over 75,000 messages per second on average. In this talk we will explore how we've use RabbitMQ in production over the last 10 years, including topologies, standards for use, monitoring, day-to-day operational management, and other technologies we use in conjunction to our RabbitMQ usage.


Pushing RabbitMQ to the limit

Gabor Olah

One of the most frequent questions I’m asked about RabbitMQ is whether it can do a specific throughput. My answer is almost always is that it depends. In this talk I will explain what affects RabbitMQ performance through practical examples. I will give a practical introduction to how to use PerfTest, the “official” performance testing tool for RabbitMQ to simulate different workloads over different topologies.

Zero Trust RabbitMQ with HashiCorp Vault

Rob Barnes

Securing RabbitMQ in a Zero Trust environment has multiple layers that need consideration. The first is implementing the principle of least privileged access to RabbitMQ, and the second is ensuring the confidentiality and integrity of application data. Both of which are difficult challenges to solve and introduce substantial operational overheads. In this demo-driven talk, I will show how you can use HashiCorp Vault to offset the operational overhead of Identity and Access Management. I will also show you how you can use HashiCorp Vault’s API to implement a simple workflow that offsets the complexity of cryptography to Vault. By the end of this talk, you will learn how to configure Vault using Terraform to broker application identity on behalf of RabbitMQ and refactor a simple Go application to implement this authentication workflow. You will also learn how to implement symmetric and asymmetric encryption of your application data before placing it on RabbitMQ message queues.

Why does RabbitMQ stop and what can be done about it

Johan Rhodin

Depending on a certain number of factors, the job of a support engineer for CloudAMQP may vary. Every now and then RabbitMQ stops, and Johan has to work quickly to get it up and running, and after that, he needs to make bug reports, sometimes build features around it, and educate other customers. In this talk, Johan will walk you through the most common issues, and how he troubleshoots them, and he will share knowledge gained from mistakes made by us, customers, and the community through his own experience.

Management, Monitoring and Tracing in RabbitMQ

Rohini Senthil

This session presents a walkthrough of RabbitMQ's Management Plugin and Firehose Tracer, highlighting how they help in addressing the difficulties faced while introducing external monitoring, by providing management and tracing capability in RabbitMQ nodes. As this capability is often crucial to the overall development and debugging process, this session will also showcase a live-coding on how they can be leveraged in building custom tools for monitoring & tracing, tailored to an application’s need. To demonstrate the potential of building custom tools the session will close with a small demo of Rabbitrace, a custom management extension built by the speaker.

RabbitMQ Performance Improvements

David Ansari & Michal Kuratczyk

An ideal message broker allows for high throughput and low latency while keeping hardware resource usage as low as possible. This talk presents tooling that helps improve RabbitMQ performance. We provide examples of how we spotted and fixed bottlenecks in the RabbitMQ broker. We show how you can leverage these tools to profile and further optimise the broker given your specific application workload.

Fun, interesting and common RabbitMQ use cases

Lovisa Johansson

We as human beings have always sought ways to communicate, even when there have been distances between us. The same need exists in the computer world - a method to send, receive, and create the message itself. Despite that, I often get the question; “Where would a message queue fit in my architecture?” Get ready for an answer to that question from the lens of common RabbitMQ use cases that are understandable no matter where you are or what language you’re speaking.

David Ansari & Michal Kuratczyk

Approaching cloud-native RabbitMQ

Iliia Khaprov

In this talk we explore RabbitMQ as a centerpiece of serverless/cloud technologies. Using Knative RabbitMQ integration as an example we will learn about Serverless, Cloudevents ecosystem, Observability frameworks and OpenTelemtry Messaging Semantic Conventions.


Keynote: Quorum Queues: a retrospective

Karl Nilsson

Quorum Queues were release in RabbitMQ 3.8 in October 2019 and in 3.10 received a whole bunch of requested features such as message TTL and at-least-once dead lettering. This session will look back at the history of Quorum Queue development and look at the various design decisions that were taken and discuss what worked and what didn't and what the future may look like.
