The temperatures have dropped again but the days are lengthening. And, it is not too long ago since we started 2023, a year full of opportunities in the world of real-time data streaming. We are happy to announce the last release of 2022, Axual Platform 2022.4.
In this blog you can learn what Axual Platform 2022.4 brings to Apache Kafka users, such as a rich and clean Self-Service interface with enriched topic graph, stream insights. Last but not least, from this release you are in control of who is able to browse your topic’s data in any environment. Continue reading this blog to learn more.
The new UI is now generally available
In the last release we introduced our revamped and improved user interface. Since then, we have collected all kinds of bug reports and improvement ideas and we believe it’s time to announce the new UI as the default for Axual Platform going forward. It includes:
- Enriched dashboard, with “My streams” and “My applications” widgets for each access to the assets you own
- Schema explorer: browse through the organization’s schemas and show details and schema versions
- Insights (see below)
- Enriched topic graph (see below)
Enriched topic graph
One of the most beloved features of our platform is the topic graph, where users can navigate through the different environments where topics are created and applications are interacting with them. By clicking the application or topic, we are now showing application and topic metadata which, together with highlighting in the graph, helps to quickly understand the context of the application or the topic. Clicking the “View stream” or “View application” takes you to the detail pages of the respective stream or app.
In a future update we are going to make navigating the streaming landscape even more user friendly by introducing filter and search possibilities.
Stream Insights
We have now integrated metrics in the user interface, starting with “Message rate”, the amount of messages produced on a topic. The stream detail page shows the current message rate on the topic for every environment and below the graph, the historic message rate can be seen.
By clicking the “Insights” tab, you can select a specific interval of your interest.
In future releases we will add more valuable metrics to the user interface.
Stream Browse access control
Streaming platforms like Apache Kafka take a central place in an organization and many applications interact with the data on the topics created on the platform. Access to the topics is given on a need-to-have basis and only the necessary permissions are assigned. We support topic authorization approval workflows to guarantee just that. However, it is not only about applications interacting with a streaming platform. Applications are built by people and when things go south, an engineer needs to dive into the details to research and ultimately solve the problem.
In the 2022.4 release of the product we are introducing “Stream Browse Access Control”, a way for stream owners to grant permissions to anyone in the organization.
Any person in the organization trying to get access to a topic in an environment where he doesn’t have the permission will be presented with a warning explaining why access is blocked.
Phasing out Axual CLI for platform deployment
When we introduced Axual Platform in 2016, the only deployment option we supported was docker. To orchestrate deployment of our platform components and to configure them as desired, we created a set of deployment scripts named Axual CLI. A couple of years later we introduced support to deploy Axual Platform on Kubernetes infrastructure by using helm charts. This has now become the default and now that none of our customers are using Axual CLI anymore for deployment.
Strimzi upgrade
Axual Platform is based on the Strimzi Operator. For the 2022.4 release we have upgraded to Strimzi 0.32.0. It allows for an upgrade to the 3.3.1 release of Apache Kafka. The operator instructions contain upgrade steps related to Axual Operator 0.13.0 to upgrade to Kafka 3.3.1. You can find the operations documentation here. A more extensive list of updates done to Axual Platform can be found in the release notes.
Experience Axual yourself
On a personal note, I am extremely excited to share these updates. It’s our mission to make streaming (and Kafka) simple. Our complete event streaming platform based on Apache Kafka comes with self-service, data governance and security functionalities to achieve this mission.

In this blog, we explore how the Model Context Protocol (MCP) enables AI applications to move beyond text generation and interact with systems like Kafka through structured actions. We will look at how natural language intent can be translated into real operations such as managing topics, schemas, and streaming applications, while also touching on governance, security, and the role of declarative approaches like KSML.
The Axual 2026.1 release builds on the improvements in governance, observability, and self-service introduced in 2025.4, and takes things a step further. This release adds audit event coverage across platform resources, giving teams more visibility and control over what’s happening in the platform. We’ve also extended OAuth support to all data plane components, making security more consistent end to end. On top of that, updates to Connector management and the Overview Graph make the platform easier to use and give clearer insight into platform activity.
Axual 2025.4, the Winter Release, expands on the governance and self-service foundations of 2025.3 with improved KSML monitoring and state management, an enhanced Schema Catalog, and usability improvements across Self-Service and the platform.
