Hi Spring fans! In this installment we look at the just-announced Spring Cloud Circuit Breaker project, which provides an abstraction atop Netflix' Hystrix, Resilience4J, Alibaba's Sentinel and Spring Retry and supports reactive and non-reactive circuits.

I am pleased to announce the release of Spring Boot for Apache Geode and Pivotal GemFire (SBDG) 1.0.0.RC1.

This is another significant milestone and SBDG 1.0 is less than a week away from final GA.

The new bits, org.springframework.geode:spring-geode-starter:1.0.0.RC1, are available in the Spring libs-milestone repository, here.

What’s New

This release adds several new features with some significant improvements and important bug fixes:

• Added auto-configuration support to automatically configure a GemfireTemplate for each GemFire/Geode Region defined in the GemFire/Geode cache. Read more

• Added chapter on "Auto-configuration vs. Annotation-based configuration" to the reference guide. Read more

• To compliment the chapter, added a new sample to explain and show Spring Boot’s auto-configuration support for GemFire/Geode in action. Read more

• Fixed a bug in the HTTP client used to push cluster configuration from a client to a standalone GemFire/Geode cluster, or PCC environment, with Security (Auth) enabled. Read more

• Switched Reference Docs to the HTML5 format. See here.

Background

When using a microservices architecture to build our applications, it is very common to end up with a pretty complex dependency tree amongst services. If the service down the dependency tree encounters an issue that causes it to start to respond slowly, it ends up causing a set of issues that cascade up the dependency tree. As more and more requests come in to the application, more and more resources may be consumed by waiting for the slow service to respond. Even worse, the additional load being put on the slow service may exacerbate the problem. To help alleviate the effect of…

Hi Spring fans! What a week it's been! When we last spoke I was in Capetown, South Africa or Johannesburg, South Africa. I've since been to Mauritius, back to Capetown, Serbia (for the amazing ITKonekt conference) and I'm now staring at the beautiful Bund river in beautiful Shanghai, China as I write this.

We've got a ton to get to this week, as usual, so let's get to it.

This blog post is the second in a series of posts that aim at providing a deeper look into Reactor's more advanced concepts and inner workings.

It is derived from my Flight of the Flux talk, which content I found to be more adapted to a blog post format.

I'll update the table below with links when the other posts are published, but here is the planned content:

1. Assembly vs Subscription
2. Debugging caveats (this post)
3. Hopping Threads and Schedulers
4. Inner workings: work stealing
5. Inner workings: operator fusion

If you're missing an introduction to Reactive Streams and the basic concepts of Reactor, head out to the site's learning section and the reference guide…

Hi Spring fans! In this installment of Spring Tips Josh revisits RSocket, the reactive application protocol from, among others, Facebook, this time looking at the brand new Spring Framework 5.2 and Spring Boot 2.2 integration.

speaker: Josh Long (@starbuxman)

Here's the first Spring Tips installment introducing the "raw" RSocket protocol and Java client library

Since we announced Spring Framework official support for Kotlin in January 2017, a lot of things happened. Kotlin was announced as an official Android development language at Google I/O 2017, we continued to improve the Kotlin support across Spring portfolio and Kotlin itself has continued to evolve with key new features like coroutines.

I would like to take the opportunity of the first milestone of Spring Framework 5.2 to give a status overview of where we are when it comes to Spring and Kotlin. And I will make my best to focus on concrete improvements since I believe Spring and Kotlin share…
