Message Router is a REST API on top of Kafka. We can’t replace any other messaging framework with the Kafka.

Let me know where i can find. [dgl: see https://onap.readthedocs.io/en/latest/submodules/dmaap/datarouter.git/docs/index.html] Also kindly clarify me on the below 1. Is kafka used in DR as well? [dgl: No kafka in DR. DR uses local file system to store client date until its delivered. It also uses mariadb to store provisioning data] 1. What is the exact use of DMD and Bus Controller? Need an example use case. [dgl: example use cases for Bus Controller: 1. Application X publishes to DR and creates Feed X via Bus Controller /feeds API. Analytic Function AF can subscribe to Feed X via Bus Controller /dr_subs API. Bus Controller provisions DR accordingly. 2. Designer specifies authenticated topic T. Topic is provisioned using Bus Controller /topics API. Application P can add itself as a publisher to topic T using the Bus Controller /mr_clients API. Application S can add itself as a subscriber to topic T using the same API. Bus Controller will create the topic T on MR, and also create and grant the AAF perms associated with the client actions. 1. Is it possible to replace other models instead of kafka in MR and use it? [Sunil?] 1. Which component of DMAAP does the Data translation and API translation? [dgl: no DMaaP component does data translation at this time. The DR team is considering a feature in Dublin that will offer some degree of provisioning coordination for a registered data translation service (e.g. reformat a data file). Please provide more info on a use case you have in mind. -- Regards, Prakas P, Network and Technology IT, -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
