The following interfaces are consumed by DMaaP

...

  • Message Router (MR) - Message Router is a reliable, high-volume pub/sub messaging service with a RESTful HTTP API. It is intended to be deployed by Platform Service providers so that it is available to Platform clients as a web service. The service is initially built over Apache Kafka.
  • Data Router (DR) - The Data Routing System project is intended to provide a common framework by which data producers can make data available to data consumers and a way for potential consumers to find feeds with the data they require. The interface to DR is exposed as a RESTful web service known as the DR Publishing and Delivery API
  • Data Bus Controller (BC) - Provisioning API of the Data Movement Platform that can be used for provisioning topics in the Message Router and feeds in Data Router.

4. Known system limitations
