Lusheng,
We are working on exposing the Kafka through the NodePort and it will be
available by end of this week. DMaaP will permit the mixed use between the MR
REST API and Kafka client API.
Thanks,
Sunil

Christina,
The DMaaP team does have native Kafka API support included as part of
Casablanca scope per their release planning:
https://urldefense.proofpoint.com/v2/url?u=https-3A__wiki.onap.org_display_DW_DMaaP-2BR3-2B-2D-2BM1-2BRelease-2BPlanning&d=DwIGaQ&c=LFYZ-o9_HUMeMTSQicvjIg&r=t27CRRmn7U12dnOvcSPfcQ&m=V6AWEk0l0CEkJqAxVOS_zsqZelKbkt_FYX4kA_VDeNI&s=FBCzMbBk1BGsCwIIHhND3rRpdfPMyD8OOcHcnNj-e74&e=
. We will need DMaaP team’s help understand exactly how to integrate.
I also have a question on whether this permits mixed uses between Rest API
and Kafka API, that is: one side (either pub or sub) uses Rest API while the
other side uses Kafka, or some subscribers/publishers use Rest while other
subscribers (of the same topics) use Kafka API. One of the uses that we may
encounter is whether we can have VES collector publishes to DMaaP Rest API
while PDNA receives over native Kafka.

We are working on integrating PNDA applications with the DMaaP

In a first phase, we would like to cross-post topics between PNDA and DMaaP
and process the streams of messages. For this, we have created a test
environment where we are posting directly to the Kafka broker underneath the
DMaaP component. We understand that the DMaaP component is meant to be used
through its REST endpoint. As pointed by Donald in the Story above, we are
concerned about the performance impact of switching to the DMaaP REST endpoint
instead of directly using a Kafka endpoint. Could you detail your view on the
matter of performance and what the preferred method would be?
Alternatively, we propose having a Kafka endpoint exposed as a NodePort
or running a Kubernetes container as a Kafka forwarder.
Looking forward to your feedback!
Best regards,
