In the context of cloud-native applications the topic ‘reactive’ becomes more and more important, since more efficient applications can be built and user experiences can be improved. If you want to...
Using the OpenJ9 JVM for Quarkus Applications
As defined on the home page, Quarkus is “a Kubernetes Native Java stack tailored for OpenJDK HotSpot and GraalVM”. Since I’m a big fan of OpenJ9, I’ve quickly measured memory usage of my reactive s...
Comparing synchronous and asynchronous Access to Postgres
Quarkus supports imperative as well as reactive programming styles. In this article I compare access times to Postgres from Java based microservices developed with Quarkus. For synchronous invocati...
Invoking REST APIs asynchronously with Quarkus
Recently I blogged about how to develop reactive REST APIs with Quarkus. Developing the actual endpoints asynchronously is the first step. To leverage reactive capabilities maximally though, the co...
Developing reactive REST APIs with Quarkus
This article describes how to implement reactive REST APIs in Java with Quarkus rather than using synchronous endpoints. In order to do this, the Java classes CompletableFuture and CompletionStage ...
Reactive Messaging Examples for Quarkus
Quarkus provides several different reactive messaging capabilities. The open source project cloud-native-starter uses some of these capabilities in a sample application which are described in this ...
Accessing PostgreSQL in Kubernetes from Quarkus
The open source project cloud-native-starter describes how to develop reactive applications with Quarkus. One of the demonstrated functions is reactive access to PostgreSQL. This article describes ...
Accessing Apache Kafka from Quarkus
This article describes how to develop microservices with Quarkus which use Apache Kafka running in a Kubernetes cluster. Quarkus supports MicroProfile Reactive Messaging to interact with Apache Ka...
Development of Reactive Applications with Quarkus
In the context of cloud-native applications the topic ‘reactive’ becomes more and more important, since more efficient applications can be built and user experiences can be improved. If you want to...
Podcasts about Cloud-Native-Starter Open Source Project
I had the pleasure to get interviewed in two airhacks.fm podcasts by Java guru Adam Bien. It was a lot of fun. The first podcast #63 NodeJS, MicroProfile and Java Cloud Native Starter was primaril...
