Spring Cloud Data Flow 1.3.0.M3 released

We are pleased to announce the 1.3.0.M3 release of the Spring Cloud Data Flow and its associated ecosystem of projects.

Release Highlights

Stream updates and rollback

A streaming data pipeline orchestrated as a series of microservice applications has always been the core value of Spring Cloud Data Flow’s design. In 1.3.0.M3 we have provided the ability to update sources, processors, and sinks independently without having to undeploy and redeploy the entire stream.

The stream update feature is implemented by delegating the deployment process to a new Spring Cloud project called Skipper. Introduced in this blog, Spring Cloud Skipper is a standalone server that deploys Spring Boot applications to multiple cloud platforms. It also keeps track of the application version, application properties, and deployment properties of the deployed application or applications so that the changes to any of these properties can be calculated upon an update request.

When a request is made to update applications in a Stream, only the application or applications that need to be changed are updated. A simple red/black update is performed and the design relies on Spring Boot’s health endpoint associated with the new application(s). By keeping track of the deployments, Skipper can also rollback to previous versions of the stream.

The following new Data Flow commands show the basic lifecycle of updating the log sink from version 1.1.0 to version 1.2.0 and then rolling back to 1.1.0. This assumes that both version 1.1.0 and 1.2.0 of the log sink were deployed as maven artifacts. Note that the HTTP source application remains deployed throughout the changes to the log sink.

dataflow:> app register --name http --type source --uri maven://org.springframework.cloud.stream.app:http-source-rabbit:1.2.0.RELEASE

dataflow:> app register --name log --type sink --uri maven://org.springframework.cloud.stream.app:log-sink-rabbit:1.1.0.RELEASE

dataflow:> stream create --name httptest --definition "http --server.port=9000 | log"

dataflow:> stream skipper deploy --name httptest

dataflow:> stream skipper update --name httptest --properties version.log=1.2.0.RELEASE

dataflow:> stream skipper rollback --name httptest

The Getting Started and Streams with Skipper sections of the documentation walk through the process in much greater detail.

First of all, special thanks to all community members for their ongoing active contributions to the framework!

Several JIRAs (and some GitHub issues), since the previously announced RC1, are included in this release, mostly bug fixes from early adopters and Reference Manual improvements.
