On behalf of the team, I am pleased to announce the release of the first milestone of the Spring Cloud Stream Brooklyn release train. Spring Cloud Stream Brooklyn.M1 is available for use in the Spring Milestone repository, a detailed description of its features can be found in the reference documentation. Release notes are available here and include important information on the migration path.

From a Monolith to a Release Train

Spring Cloud Stream Brooklyn.M1 succeeds Spring Cloud Stream 1.0. The change in the naming scheme reflects the project's structural changes, in particular switching…

We are pleased to announce the 1.0.0.RC2 release candidate of Spring Cloud Data Flow for Mesos, a team effort that encompasses many new features under the hood.

This release candidate builds upon the recent 1.0 GA release of Spring Cloud Data Flow. Some highlights include:

• We now run the Spring Cloud Data Flow Server as a Docker image on Marathon, a container orchestration platform for Mesos.
• This release adds features to support stream partitioning and scaling

• Currently partitioning and scaling of sinks and processors are handled by using multiple application deployments, one for each app instance, identified by an index appended to the name.
• Scaling of sources is handled by using additional application instances.

* Streams are now deployed using Marathon [Application Groups](https://mesosphere.github.io/marathon/docs/application-groups.html) so it is easier to identify the different apps making up a stream. * We have added support for launching tasks using Chronos, a fault tolerant job scheduler for Mesos.

As part of this effort we have developed a simple Java client for interacting with the Chronos API. This Java client is included in the latest 1.0.2.RELEASE version of the Spring Cloud Deployer for Mesos project…

We are pleased to announce the general availability of Spring Cloud Data Flow for Cloud Foundry version 1.0.0.RELEASE.

Spring Cloud Data Flow for Cloud Foundry provides support for orchestrating long-running (streaming) and short-lived (task/batch) data microservices on Cloud Foundry runtime.

As the successor to Spring XD, this project benefits from a much more decoupled architecture, leveraging the Spring Cloud Deployer for Cloud Foundry library, which also goes GA today. More details about Spring Cloud Data Flow’s architecture and its ecosystem can be found in this blog.

• Stream and Batch/Task Processing are the primary functionalities in Spring Cloud Data Flow and they map to Cloud Foundry Diego’s LRPs and Tasks1 respectively.

• Includes developer toolkits to build streaming and batch/task pipelines using the DSL, Shell, REST-APIs, Dashboard, Flo Designer, or any combination of those.

• Facilitates test-driven-development at individual data pipeline components along with test fixtures to develop and test "data-centric" apps in isolation.

• Leverages Cloud Foundry’s runtime capabilities such as security, metrics, operational monitoring, scaling, and reliable execution of streaming and batch/task pipelines.

Without the community we couldn’t be the successful project we are today. I’d like to thank everyone that created issues & provided feedback.

Feedback Please

If you have feedback on this release, I encourage you to reach out via StackOverflow, GitHub Issues, or via the comments section. You can also ping me @rob_winch or Joe @joe_grandja on Twitter.

Of course the best feedback comes in the form of contributions…

We are pleased to announce the 1.0.0.RC1 release of Spring Cloud Data Flow for Cloud Foundry.

As we near completion towards a GA release in the upcoming days, this milestone brings the following improvements:

• Builds upon the 1.0.0.RC1 release of Spring Cloud Deployer Cloud Foundry, which itself builds upon Project Reactor 3.0.0.RELEASE and of CF-Java-Client 2.0.0.RELEASE

• Adds the ability to orchestrate short-lived tasks including Spring Batch Jobs in Cloud Foundry, which can be enabled as an experimental feature toggle

• Adds support for command line arguments as a separate set of properties to be passed to a Task when it’s launched

• Adds support to separate stream and task specific service bindings. This allows pinning stream and tasks specific services to stream and task applications respectively

It was brought to our attention that the spring-security-saml sample application contained an XML External Entity (XXE) vulnerability. This meant that a malicious user could view any file that the Spring Application’s process had access to.

The issue was a direct result of OpenSAML Java ParserPool and Decrypter Vulnerable To XML Attacks. The default behavior of the ParserPool implementations is fixed in OpenSAML 2.6.1+ (which Spring Security SAML uses). However, the vulnerability is still possible if users construct their own ParserPool without the proper settings.

Note

We did not consider this a CVE because the exploit was only found in the sample application which is not considered production code. However, we expect that our users may have copied this code to create their own applications. For this reason, we wanted to be transparent and communicate the issue and…

Welcome to another installation of This Week in Spring! This week I'm in NYC (for the NYC Java SIG), Austin and San Francisco (for the Silicon Valley Spring User Group) talking to customers and doing meetups! We've got a lot to cover, as usual, so let's get to it!

• Spinnaker is a continuous delivery platform from Netflix built on Spring Boot. It supports a build-and-bake pipeline and works naturally with Spring Boot and various cloud platforms. It's enjoyed contributions from Microsoft, Google and Pivotal. In this post, Spring ninja Greg Turnquist introduces Spring Cloud Spinnaker 1.0.0.M1. Definitely worth a look!
• this seemed interesting - a code generator that supports Spring-based applications called Sifu

I am pleased to announce that the Spring for Apache Kafka 1.1.0.M1 milestone release is available now.

As usual, thanks to the community for any feedback and contribution as always!

Highlights of this release:

• Support for the 0.10.x.x client (use 1.0.x for the 0.9.x.x client)

• Support for listeners that receive the entire batch of messages returned by the consumer.poll() operation

• Support for null payloads - used to delete keys when using log compaction

• Allow setting the initial offset to be relative to the current offset
