- 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 APIData Movement Director (DMD) - A client to DMaaP platform to publish & subscribe data.
- Data Bus Controller - Provisioning API of the Data Movement Platform
Futher detailing will be done later.
4. known system limitations
...
- that can be used for provisioning topics in the Message Router and feeds in Data Router. In addition Bus Controller is also used for provisioning Mirror Maker capability between two Message Router instances to replicate messages
4. Known system limitations
Current know system limitations
- DMaaP uses persistent volumes to store data used by topics and feeds. Persistent volumes need to have enough storage space to handle anticipated volume.
5. Used Models
DMaaP uses the following models:
??
does not use any models.
6. System Deployment Architecture
DMaaP consists of 2 containers:
...
of 3 main components:
- DMaaP Message Router
- DMaaP Data Router
- DMaaP Buss Controller
