The 1.1.1.RELEASE maintenance release of Spring Cloud Data Flow for Cloud Foundry is now available and includes a variety of stability and performance improvements. Following are the highlights:

• Stability Improvements The instability problems when using SCDF’s 1.1.0.RELEASE on PCF manifested to the users in the following forms.

  • stream list operation would hang and eventually time out with “IllegalStateException: 503 Bad Gateway” or “IllegalStateException: Timeout on block read” exceptions. This is addressed in the cf-java-client library.

  • With SCDF server sitting cold/idle for a period of time and with OAUTH token refresh routine happening in the background, any new operation to the server would never complete. The OAUTH refresh token routine had a bug in successfully negotiating for new tokens. This is addressed in the cf-java-client library.

Hi Spring fans! In this tip, we'll look at jOOQ (a fluent API for typesafe SQL query construction and execution) to quickly and easily interface with our SQL database.

On behalf of the team, I am excited to announce the release of the first milestone of Spring Cloud Data Flow 1.2.

Note: A great way to start using this new release(s) is to follow the release matrix on the project page, which includes the download coordinates and the links to the reference guide.

Over the last few weeks, we have added new features and improvements to the overall orchestration of data microservices. The following new features were included in the 1.2.0.M1 release:

Core

• Introduce dedicated prefixes for deployment properties. Using the deployer properties is as simple as deployer.<appname>.xxx as opposed to app.<appname>.spring.cloud.deployer.xxx
• Introduce a new REST-API controller and shell support to cleanup Task Executions
• Foundation work to consolidate the use of controllers between Task deployments and Task Executions
• Consolidate REST-API call traces and return codes for consistency
• Adds role-based access control to define who has access to create, deploy, destroy, or view streams/tasks. This works seamlessly in coordination with the supported authentication methods…

What do things like Minecraft, a light bulb and your music library have in common? Well, nothing really. Until you come up with this crazy idea to link them together. This is where application orchestration comes in.

In this session, you’ll learn how Spring Cloud Data Flow allows easy composition of microservices together. As the spiritual successor to Spring XD and the natural sidekick of Spring Cloud…

Recorded at SpringOne Platform 2016. Speaker: Christian Posta, Redhat Slides: http://www.slideshare.net/SpringCentral/real-world-microservices-with-spring-cloud-netflix-oss-and-kubernetes

Building distributed systems - whether we call them SOA or microservices - is not easy. Open source communities like Spring, NetflixOSS and Kubernetes bring decades of experience building these systems, but the question always begs to be asked "do we implement these patterns in the application layer or in the infrastructure layer"?

This is a Java developer-oriented presentation showing developers how to…

Recorded at SpringOne Platform 2016. Speaker: Andreas Evers, Ordina JWorks Slides: http://www.slideshare.net/SpringCentral/writing-comprehensive-and-guaranteed-uptodate-rest-api-documentation

RESTful APIs are eating the world, yet all too often the documentation can cause indigestion for the APIs' developers and their users. Developers have to deal with annotation overload, repetition, and an unpleasant writing environment. Users are then left with documentation that's inaccurate and difficult to use. It doesn't have to be this way.

This talk will introduce Spring REST Docs and its test…
