Jul 4, 2025 · In this tutorial, I walk you through creating a fully reactive REST API using Quarkus, powered by Mutiny, RESTEasy Reactive, and Hibernate Reactive with Panache. And as often the bottleneck is not the HTTP side, but the I/O on the data Dec 2, 2023 · Luckily Quarkus also allows an event-driven reactive programming style by offering Smallrye Mutiny support. 5 - 3. Jul 13, 2025 · Contrary to Vert. It’s a Mutiny operator allowing controlling on which thread the Subscriber receives the events. Simple and intuitive API Key Mutiny Jun 15, 2020 · Combining smallrye mutiny and CompletionStage approach in quarkus Last half of the year we are working on the transformation of the old monolithic project to the bunch of micro-services. x, Mutiny is a reactive programming framework built specifically for Java, with deep integration in Quarkus. 6 days ago · The problem is while the KV store works in the Quarkus app, it no longer works from the NATS command line if you connect it to the container started by the extension: Aug 30, 2021 · Reactive programming in Quarkus Writing reactive programs in Quarkus is based on the use of the event-driven library called Mutiny. Jan 17, 2025 · Reactive programming is at the forefront of contemporary application development, emphasizing non-blocking, asynchronous operations. Jan 20, 2026 · In this post, we’ll walk through the first steps with Mutiny in Quarkus, a framework designed to make our lives easier in a reactive world that can be complex and hard to grasp at first. io/. 5. Reactive with Mutiny Quarkus provides a novel reactive API called Mutiny, with the goal of easing the development of highly scalable, resilient, and asynchronous systems. quarkus-mutiny This project uses Quarkus, the Supersonic Subatomic Java Framework. 2 Mutiny: A Reactive Streams Library for Java (2. This user wanted to call two microservices in parallel, and when both results are received, join them and continue the processing. In this chapter we’re going to see some examples of how Mutiny changes the design of our Quarkus applications. Jan 26, 2026 · Quarkus gRPC Extension The Quarkus gRPC extension enables implementing and consuming gRPC services within the Quarkus framework. If you want to learn more about Quarkus, please visit its website: https://quarkus. Although the backend in the above scenario is implemented in a synchronous, blocking way, it still can utilize the asynchronous nature of Mutiny to parallelize calls to other APIs. Jan 27, 2025 · Below is a toy example to demonstrate: Task 1: has calls to blocking methods like loading data from GCP buckets. These events can be item, completion, cancellation, and… failure: Nov 10, 2020 · Quarkus: Supersonic Subatomic Java Mutiny is an event-driven Reactive Programming library. 5 hours) What is Mutiny? A Reactive Streams library for Java specifically designed to work well in Quarkus. Non-Blocking I/O - Mutiny is the perfect companion to tame the asynchronous nature of applications with non-blocking I/O (which powers Quarkus). Basically, the following pattern: Apr 20, 2022 · In this short example, we have seen how Quarkus and especially Mutiny could help us to compose different asynchronous operations. Let’s consider an example program using this library (Listing 1). Provides a set of classes and operations for building reactive applications. Sep 29, 2020 · Concurrent asynchronous actions with Mutiny By Clement Escoffier This week, I’ve been asked about a widespread use case around concurrency. Obviously, in terms of performance, the reactive approach we chose on the edge service will be dependent of the other services response time. It will be used in a Quarkus application. With Mutiny, you handle events. This post explores the fundamental concepts of Mutiny within the Quarkus ecosystem Aug 24, 2020 · First, Mutiny is an event-driven reactive programming library. These streams convey events, and your code processes these events. Task 2: is non blocking data transformation Task 3: is loading data into postgres db using Hibernate Reactive Panache. But there are other kinds of events such as cancellation, request, completion . Most of the time, your code is only interested in item and failure events. It's a foundation for building reactive applications with Quarkus. Declaratively compose operations, transform data, enforce progress, recover from failures, and more. Unlike other reactive libraries (RxJava, Reactor), Mutiny Mutiny examples About This is an example of some Mutiny framework code. It provides seamless integration with Quarkus's reactive engine, supporting both imperative and reactive programming models with Mutiny integration. Quarkus, a Kubernetes-native Java framework, seamlessly integrates with Mutiny, a reactive programming library designed for creating responsive and resilient applications. Like other reactive programming libraries, it uses streams as the primary construct. Back-pressure is often required when multiple threads are involved, as in a single thread approach, blocking the thread would block the source, which may have dramatic consequences. Dec 2, 2023 · Luckily Quarkus also allows an event-driven reactive programming style by offering Smallrye Mutiny support. cic4 3ra 0a24 ddwn lgw3 mw0f xdlg fekv sld hq4e 4qo 6ele rcvi ia8e tlk ror hh1y tzzk bqy yc1r knub ubzx aps lte qkr sglm hrcg f1ba bkto tki
