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.

Flight of the Flux 2 - Debugging Caveats

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. Concurrent Agnostic
  4. Schedulers and publishOn vs subscribeOn
  5. Inner workings: work stealing
  6. Inner workings: operator fusion

Introducing Spring Cloud Circuit Breaker

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 these types of cascading failures, it is common practice to use circuit breakers as part of microservice applications.

This Week in Spring - April 16th, 2019

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.

What’s Next

Some of the proposed and upcoming features in the SSDG 2.2 release line include:

  • Attached Sessions (option).

  • Stronger Consistency (option) using Map.replace(key, oldValue, newValue) for lightweight transactions supplanting the need for heavier, cache/local transactions.

  • Improvements in PDX Serialization support.

  • And much more…​
