Protobuf support in nussknacker

[vishnu s r]

Hi,

I am testing nussknacker for my project and I was trying to integrate the nussknacker with exsiting kafka. I was able to connect to it. We are using protobuf for our project . Is protobuf supported in nussknacker? 

Thanks a lot!

Hi,

Currently we support only avro and json schema formats, but adding protobuf schemas should be quite easy because mechanism of distinction between various formats is already implemented.

Moreover confluent schema registry client supports this format: https://docs.confluent.io/platform/current/schema-registry/serdes-develop/serdes-protobuf.html and we use it under the hood so some part of work will be easier to do.

Our team don't have plans to add protobuf in near future, so contribution would be welcome.

As a work around, I recommend you convertion between protobuf and other format that is already supported. Maybe kafka-connect has some option to do it?

Cheers,

Arek
