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:

SCDF Helm Chart and Apache Kafka

With continued interest from the community, as of v2.0.2, we have now added support to toggle between RabbitMQ and Apache Kafka when using SCDF’s helm chart. Though the chart is in the PR status in Helm repository, you could still try it out and give us feedback.

Docker Compose and Apache Kafka

To continue with the same trend in regards to Apache Kafka, along with regular Apache Kafka binder properties, we have now also added support for Kafka Streams binder properties; likewise, we have switched to use the official Confluent’s Docker image as part of the Docker Compose getting-started experience…

Dear Spring Community,

I am happy to announce the 4.2.1 release of the Spring Tools 4 for Eclipse, Visual Studio Code, and Atom.

Highlights from this release include:

• (Spring Boot) performance: additional performance and memory footprint improvements to symbol indexing, now eats less memory and is faster while doing the initial indexing run
• (Spring Boot) new: content-assist for bean types in Spring XML config files
• (Spring Boot) new: content-assist for property names in Spring XML config files
• (Spring Boot) new: content-assist for bean references in property definitions in Spring XML config files (very rough early cut, needs a lot more work on proposal content, number of proposals, and sorting)
• (Eclipse) fixed: empty property values in custom properties not set when launching boot apps (#275…

We have released Spring Cloud Config 2.1.2, 2.0.4, and 1.4.6 to address CVE-2019-3799: Directory Traversal with spring-cloud-config-server. Please review the information in the CVE report and upgrade immediately.

These fixes will be included in the next release of the respective Spring Cloud release train.

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…
