Welcome to the first of our newly reformatted Quarkus newsletters - focused on helping you to get the best out of Quarkus and related technologies.

Wherever you are in your journey this newsletter will help you move forward.  Expect to see information covering the breadth of the Quarkus ecosystem, discussions with the engineers creating these amazing technologies, practical guides, wider looks at the Cloud and Kubernetes space and of course relevant insights into what’s happening  in the wider Java community in general.


Quarkus 2.0 featured image

Quarkus 2.0 is here!

We like to say Quarkus is “Supersonic, Subatomic Java,” and we don’t just mean making your applications lightweight and blazing fast.  Quarkus is also about making your teams supersonic, with minimal effort and code. Quarkus 2.0 doubles down on our mission to bring “Developer Joy,” boosting your productivity and optimizing your workflow with time-saving capabilities like Live Continuous Testing and Dev Services. You’ll see instantaneous test results as you code - without lifting your hands from the keyboard. And, thanks to Dev Services, you will avoid the mundane task of configuring and starting a database. It will just appear when you need it. 

Of course, it wouldn’t be Quarkus without mind-blowing performance, so Quarkus 2.0 also brings lightning-fast REST with RESTEasy Reactive. RESTEasy Reactive build-time optimizes your HTTP handling, whether you use imperative or reactive programming, and it’s all built on the next generation Vert.x 4. The move to Vert.x 4 is another significant change in Quarkus 2.0, improving the full stack’s reactive capabilities and boosting overall performance.

Although what’s most impressive about 2.0 isn’t any particular feature, it’s the fantastic Quarkus community who shared their passion and ideas along the way. We hope that you will find using Quarkus 2.0 as blissful as we felt building it.

Data is the New Gold – How to Work with Databases in Quarkus

By Daniel Brintzinger

By using Quarkus you can write lightweight and lightning-fast Java applications that scale on OpenShift/Kubernetes in a matter of milliseconds. But to achieve linear scalability and resilience of your application you should strive to create stateless applications. If you scale up multiple application instances that all connect to the same database, this will result in a bottleneck essentially halting all performance gain after a certain threshold. Learn More
