The Reactor team is happy to announce the release of 2.0.0.RC1, which is now available in the spring.io Maven repository as well as Maven central. Version 2.0 is an #uberupdate from Reactor version 1.1 and contains several new components as well as complete rewrites of important classes like Stream, which now implements the Reactive Streams standard. Please note that the Maven coordinates for Reactor 2.0 have changed from those for Reactor 1.x. The new coordinates all fall under the group ID io.projectreactor rather than the previous org.projectreactor. A sample dependencies block for a Gradle…

The Reactor team is frankly a little giddy at finally being able to announce an initial milestone release of Reactor 2.0! This update includes a fully-compliant Reactive Streams implementation in the completely re-written Stream and Promise APIs! This is a huge step for Reactor users. It opens up integration with other Reactive Streams implementations like Akka Streams, Ratpack, RxJava and others. Reactor provides a solid foundation upon which to build modern #uberfastdata applications with demanding high-throughput and low-latency requirements. Stream and Promise The headline change in…

The Reactor team is pleased to announce that some significant updates to the Reactor framework are now available in the 1.1.0.RELEASE version of Reactor's flexible, asynchronous, fast data framework. This version includes numerous bug fixes and rewrites of key components to make them faster and, maybe more importantly, more efficient in terms of memory usage. Reactor 1.1 now includes the fantastic gs-collections library from Goldman Sachs [1] which provides a very fluent API for dealing with maps and collections of all kinds. Here is a non-exhaustive list of changes between Reactor 1.0 and 1.…

I'm happy to announce that Reactor, a powerful foundational library for building reactive, fast data applications on the JVM has reached GA! What is Reactor and why should I care? Reactor provides the necessary abstractions to build high-throughput, low-latency--what we now call "fast data"--applications that absolutely must work with thousands, tens of thousands, or even millions of concurrent requests per second. You should care about Reactor because modern applications with non-human consumers--like mobile phones and the apps that run on them--generate more data than traditional thread-per…

I'm super excited to announce the first milestone release of Project Reactor! Project Reactor is a foundational framework for building asynchronous, FastData applications on the JVM. Some of the goodness in Reactor 1.0.0.M1 includes: reactive composition helpers Stream and Promise, a TcpServer and TcpClient, and Groovy and Spring support. Inspired by Reactive Extenstions, RxJava, the new JDK 8 Stream API (and Scala, and others...), these Composables make coordinating asynchronous tasks dead simple. They support traditional callback-style programming using Consumers, but they also offer a…

We’re pleased to announce that, after a long period of internal incubation, we’re releasing a foundational framework for asynchronous applications on the JVM which we’re calling Reactor. It provides abstractions for Java, Groovy and other JVM languages to make building event and data-driven applications easier. It’s also really fast. On modest hardware, it's possible to process over 15,000,000 events per second with the fastest non-blocking Dispatcher. Other dispatchers are available to provide the developer with a range of choices from thread-pool style, long-running task execution to non…

I'm pleased to announce the release of Spring Data REST 1.0.0.RC3! This release includes a significant number of bug fixes, changes to the structure of the JSON representation, better integration of user-defined Jackson Modules that are bootstrapped into the internal ObjectMapper, as well integration with Spring HATEOAS. Also included in this release is support for extending the resource representation (e.g. to add links to other, related resources) using the Spring HATEOAS ResourceProcessor abstraction. New functionality includes: Starter Web Application | Wiki | Release Notes To learn more…

I'm pleased to announce the release of Spring Data REST 1.0.0.RC2! Beyond a number of bug fixes, this release adds support for JSONPE (JSONP with error handling), the ability to turn off CRUD methods with the @RestResource annotation, and is now built and tested against the Servlet 3.0 API (though it is not yet 3.0 specific, so will still work fine in Servlet 2.5 containers). New functionality includes: New or updated documentation includes: Starter Web Application | Wiki | Release Notes To learn more about the project, visit the Spring Data REST homepage, or visit the Github repository to…
