Hi Prakesh,


No partitioning involved in DMaaP DR.

Data is published to specific "feeds" which subscribers can consume from.


See arch diagram here 
https://onap.readthedocs.io/en/latest/submodules/dmaap/datarouter.git/docs/data-router/architecture.html


Have a quick read through the API also.

Hi Team,

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]


Kindly assist me understand the below

If DR doesn't use kafka then how the partitioning of data and topics happens in 
DR? Kindly provide more info.

Can you explain the internal call flow that DR does for a single file.txt 
transfer between two applications?

Hello Team,

 As i could see a demo video on MR but i just want to know how DR works 
internally and looking for more documentation. Let me know where i can find.

[dgl: see 
https://onap.readthedocs.io/en/latest/submodules/dmaap/datarouter.git/docs/index.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__onap.readthedocs.io_en_latest_submodules_dmaap_datarouter.git_docs_index.html=DwQGaQ=udBTRvFvXC5Dhqg7UHpJlPps3mZ3LRxpb6__0PomBTQ=b3fQ5vQGBcdUCgZUGFf9IC7Lhg8psUY8W6jf9R5XqtE=3LQdIm-tMQXx1XGI9LKKmLsuMWKYAB85AgQl_27cs3k=6GfengOIC6NdK6kwYimfeR2m8dhP4AhJAnDVysRhsZA=>]

 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]

2.   What is the exact use of DMD and Bus Controller? Need an example use case.

[dgl: example use cases for Bus Controller:

a)   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.

b)   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.

3.   Is it possible to replace other models instead of kafka in MR and use it?

[Sunil?]

4.   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.
