Spring Cloud® Data Flow for PCF
Spring Cloud Data Flow is an open-source toolkit for data integration and real-time data processing (see the project home page). The Spring Cloud Data Flow (SCDF) server deploys pipelines composed of Spring Cloud Stream or Spring Cloud Task applications. A domain-specific language (DSL) makes it easy to describe the applications in a pipeline and how they are connected.
The SCDF server exposes a REST API for composing and deploying data pipelines and a dashboard with a graphical pipeline editor. It also includes a shell for working with the API from the command line.
Spring Cloud Data Flow for Pivotal Cloud Foundry (PCF) automates the deployment of SCDF and its dependent services so that developers can use Apps Manager to deploy their own SCDF instances. They can then access their Data Flow server, either via the SCDF dashboard UI or using their PCF credentials with the SCDF shell.
Spring Cloud Data Flow for PCF includes the following key features:
- Addition of the Spring Cloud Data Flow server to the Marketplace as a managed service
- Automatic integration with dependent PCF services:
- MySQL for PCF (or a user-provided relational database service) for apps, pipelines, and task history
- RabbitMQ for PCF (or a user-provided RabbitMQ or Kafka service) for event messaging
- Redis for PCF (or a user-provided Redis service) for capturing analytics data
- Integration of Data Flow server with PCF’s UAA security model
