Is Rest proxy api version v3, ready for usage?

I used v2 version and data flowing just fine, when I tried to use v3, Rest proxy is giving 200 okay, but data is not getting ingested into underlying kafka. I wonder is there some configuration i need to update in kafka brokers, before using rest V3?

I am also interested in learning more about API v3. Many of the docs/demos still use v2. Give us more examples! :slight_smile:
