Convert JSON in Arcadia Data, Ksql Connection

Hi there,

I am new to Arcadia, so would like to get some help here.

Ksql connection is created and ksql stream is created. One of the column from stream is string type, and it’s actually json format. I understand that I can create another stream to flat the json column. Somehow I don’t have permission.

Is there any other way to convert json out?

Thanks much
