The release 2.3.0 delivers a lot of enhancements and generic compatibility changes for Spring Boot 2.2.x and Spring Cloud Hoxton.
As task applications evolve faster to keep up with business needs, the ability for new versions to be consumed via Data Flow in an automated way is needed. While Data Flow has supported the ability to register multiple versions of a task application in previous iterations, the ability to run them in a practical way by re-hydrating command line arguments, deployment properties, and application properties used in previous executions has been missing. In this version, the storage of those values in a manifest and the ability to both retrieve them to determine if an application needs to be upgraded and apply them to the new execution allows for developers to create continuous deployment flows for their task applications. All these capabilities are readily available through RESTful APIs, as well, so the overall CI/CD workflow for Tasks can be automated.
Scheduling has been updated to support the Task’s CI/CD features. Thus when the Kubernetes or Cloud Foundry Task-scheduler launches the application after the user updates the Task application to a new version, the next execution in Spring Cloud Data Flow will take advantage of these updates automatically.
In this release, we have revised the monitoring architecture to drive towards a consistent experience in Local, Kubernetes, and Cloud Foundry.
The following new capabilities are readily available as deployment properties in Kubrentes for both streaming and batch data pipelines.
The addition of new scaling API is available to quickly alter the number of application instances without redeploying a whole stream with updates to the deployment properties. The Scaling API is agnostic to the target platform and can be used seamlessly with K8s, CF and Local.
We also made it easier to work with multiple environments by adding Import/Export Streams feature which provides easy moving streams across different environments, e.g. dev, test, prod.
Our journey to fully move into next generation Spring Security OAuth2 support is almost complete and we expect to finalize it in next releases. There is a blog post Next Generation OAuth 2.0 Support with Spring Security which outlined where things are going in a Spring world.
We have released one major release (2.0), three minor releases (2.1, 2.2, and 2.3), and several maintenance releases in 2019! Likewise, Spring Cloud Stream, Spring Cloud Task, Deployers, Skipper, Apps, and remaining others in the SCDF ecosystem independently evolved in isolation, as well.
