Project Name:

  • Proposed name for the project: DMaaP – Data movement as a platform
  • Proposed name for the repository: DMaaP

Project description:

DMaaP is a premier platform for high performing and cost effective data movement services that transports and processes data from any source to any target with the format, quality, security, and concurrency required to serve the business and customer needs.

...

3. Data Processing - the low latency and high throughput data transformation, aggregation, and analysis. The processing will be elastically scalable and fault-tolerant across data centers. The Data processing needs to provide the ability to process both batch and near real-time data.  


     

Scope:

DMaaP has four components:

...

  • It is based on Pub/Sub architecture, not Point to Point. Adding new subscribers (targets) for existing published feed requires no work on the publisher (Source side)
  • Agnostic to source and sink of data residing in an RDBMS, NoSQL DB, other DBMS, Flat Files, etc.
  • Does not tightly couple publisher and subscriber endpoints.
  • Ability to track completed file transmissions (via log records) 
  • Using HTTP as File transfer Protocol allows customers to utilize the language and frameworks that they are most comfortable with.
  • Does not require a contract (connectivity configuration) between two servers (not server specific Point to Point). It’s simply a contract between two applications.
  • Automatically retries delivery to subscriber for 24 hours. If it still fails, it will be marked as permanently failed.
  • User authentication for each publish request.
  • Authorization for each end point (IP of publisher) determines if allowed to publish or not.
  • Supports low latency for transmission of large files.
  • Feed can be defined with a guaranteed delivery option. This includes dealing with subscribers that are down for an extended amount of time.

Architecture Alignment:

  • How does this project fit into the rest of the ONAP Architecture?



  • What other ONAP projects does this project depend on?
    • AAF

  • Are there dependencies with other open source projects?
    • JSC (  Java Services Container )
    • DME ( Direct Messaging Engine )

    • AAF ( Application Authorization Framework )

    • Apache Kafka

    • Zookeeper.

    • Apache Tomcat

Release 1:

Release 1 provides the following features:

  • Pub/sub messaging metaphor to broaden data processing opportunities.
  • A single solution for most event distribution needs to simplify our solutions.
  • Horizontal scalability: Add servers to the cluster to add capacity. (Our initial installations are expected to handle at least 100,000 1KB msgs/sec per data center.)
  • Durability: Hardware failure in the cluster should not impact service, and messages should never be lost.
  • High throughput: Consumers must be able to distribute topic load across multiple systems.
  • Easy integration via RESTful HTTP API
