Spring Cloud Data Flow

Spring Cloud Data Flow – We are pleased to announce that 1.3.0. M2 version for cloud data flow and related enterprise ecosystem.

In this second release of Dashboard/Flo version 1.3, we have covered the essential features that support streaming and task/package operations.

Continuing to upgrade the Angular4-based infrastructure, streams and task/batch workflows now have a modern look and feel and are packed with usability improvements.

Based on popular demand from the community, customers, and industry, this release includes support for visual fan and fan for data channels. The following image shows the waving in action:

Additionally, there is a new control that allows you to branch directly from a specific node to kill streaming from that location.

It is also possible to switch the primary flow in the chassis. Just one click – it’s that easy!

Cloud Data Flow always ensures support for data channels that interact with destinations defined as producers, consumers, or both. This version adds the ability to interact with them visually and makes it easier to create a complex topology. ‘n’ groups of producers and consumers can be linked to a common destination, which is very powerful for architectures that span multiple data sources and destinations. The following image shows an example of a complex topology:

Users who resolve Maven flaws from the public or private artifact tree can now use the update policy feature. You can use this option to bypass and update the Cloud Data Flow internal cache. For example, you can constantly resolve SNAPSHOT versions of a Maven artifact in development by setting

, which forces the download of the latest version of the broadcast or batch / task application used in the DSL / dashboard.

Due to the traditional security support and OAuth in Cloud Data Flow and similar coverage requirements for its accompanying servers such as -cloud / -cloud-dataflow-metrics-collector, -cloud-task-app-starters / composite-task- runner and -cloud / -cloud-skipper Next, we separate the shared security infrastructure into a separate library. The -cloud/-cloud-common-security-config library will be reused in companion servers in future releases.

This version adds autocomplete for the stream, task/package names and other metadata. No more guessing – everything is just a tab away! For more information on advanced shell features and tips and tricks, see the following screen recording.

This release provides Boot 1.5.7 compatibility and the cloud core infrastructure is updated to Dalston.SR3. See the 1.3.0 M2 release notes for more information.

Looking ahead, we are aiming for 1.3.0 M3, followed by a filter release and then general availability by October 2017.

As always, feedback and contributions are welcome, so please contact us on Stackoverflow, GitHub, or Gitter. In this article, I will show you how you can get started with Spring Cloud Data Flow. Spring Cloud Data Flow is a great platform for data integration and pipeline processing. It has a very easy to use graphic dashboard where you can define your own streams, which makes working with data an absolute pleasure.

The goal of this article is to teach you how to create simple data lines by the time you have finished reading. Before you begin, there are some system requirements.

Spring Cloud Data Flow 1.5.0 Released

As I mentioned, middleware is required to run the platform. The first is RabbitMQ, you can use Kafka for your streaming connections, but for simplicity in this tutorial we will be using RabbitMQ:

Running this command will start the RabbitMQ Docker container on your machine, opening it to the default ports. You also get an administrative console that allows you to check the status of your broker.

You also need Redis to get analytics from Spring Cloud Data Flow. It’s not 100% required, but since it’s not much of a hassle, let’s start with it. If you are using Data Flow in a production deployment, you will definitely need:

The last condition is a MySql instance. If you don’t have one, you can feed the data stream to an in-memory H2 database. The problem is that when you restart the server, you lose all your data. This may be desirable for testing, but it is very frustrating if you spend time configuring your streams only to lose them on server restart. When the container is created, we set a custom password and create a database for the data flow:

Spring Cloud Data Flow 1.1 M2 Released

Once you have these three docker containers up and running, you are ready to run your data flow server. You can download it here: https://repo.spring.io/libs-release/org/springframework/cloud/spring-cloud-dataflow-server-local/1.3.0.RELEASE/spring-cloud-dataflow-server-release Local 1.3.0.RELEASE.jar. This is the latest version at the time of writing, the official website of the project may have a more up-to-date link, but it is not guaranteed to work.

They are executed as local java processes. Cloud Foundry and Kubernetes versions are available from the server if you want something that is production ready.

It’s time to start the server. In this startup command, we pass MySQL and RabbitMQ parameters. The default radish features are good enough:

If you wish, you can view your MySQL instance where you should see a set of tables created:

It looks a bit empty! This is because we have not downloaded any launcher. Spring Cloud Stream App Starters is a project that provides several ready-to-use starter applications for creating streams. You can read from FTP, HTTP, JDBC, twitter and more, process and save in many sources. Each application can belong to three basic concepts:

They are constantly being added, and you can see an updated list on the official website of the project. We currently have:

This is a great list! So how do we get them into the Spring Cloud data server? It couldn’t be easier! First, we’ll start with the RabbitMQ + Maven flavor, because that’s how we’re going to set up the server. The stable release URL is http://bit.ly/Celsius-SR1-stream-applications-rabbit-maven on the project site. We can forward this data stream to the server. First, click:

We are now ready to build our first data stream. For this, we head to the address

Here we create a flow that reads from the HTTP endpoint, writes the content in uppercase, and saves it all to c:/dataflow-output (if you’re on Windows, otherwise you can choose a different directory). The purpose of this exercise is to show you how the source, processor, and sink are all connected together and how smooth it all comes together! We pull the following data into the work area:

As you can see, there are red exclamation marks on the screen. This means that the flow is not healthy. You must click the small squares in the graphic to connect streams, or alternatively you can specify how the stream is configured in the text field:

With that, we just need to configure the flow accordingly. This can be done either by clicking on the gear icon of the graphic representation that appears when you select:

Or using a text field. One thing you get from this GUI is a great way to enter themes. For example, to configure this HTTP source, we can simply set the port as follows:

It wouldn’t be fun to just create a stream and not try! To do this, you can run Postman to send some requests to this HTTP endpoint:

Finally, let’s examine the file and directory where we wanted to save our broadcast results:

I hope reading this introduction got you excited about using Spring Cloud Data Flow – I definitely enjoyed writing about it! You should know that Spring Cloud Data Flow Shell is also available if you only need to work with the platform in a shell environment (or if you want to!).

Spring Cloud Data Flow

Spring Cloud Data Flow offers so much more. You can create your own sources, processors, and sinks. Instead of streams, you can create task processes (running on demand). You can design complex processing workflows. All you have to discover and use – we hope with the knowledge you gained from this article, you are ready to start your own exploration.

Technology: Spring Cloud Data Flow is a cloud-based orchestration service for compostable microservices applications in modern runtime. With Spring Cloud Data Flow, developers can create and organize a data path for common use cases such as data collection, real-time analysis, and data import/export. It is a tool for deploying/hosting Java-based microservices and also a dashboard/screen for Java-based applications to check the behavior and health of Java-based microservices, it provides multiple instances of the same applications and also provides complete details of user rudimentary actions from user interface or shell.
