Does spark support automatic detection of schema from a json string in a dataframe.
I am trying to parse a json string and do some transofrmations on to it (would like append new columns to the dataframe) , from the data i stream from kafka. But i am not very sure, how i can parse the json in structured streaming. And i would not be interested in creating a schema, as the data form kafka is going to maintain different schema objects in value column. Any advice or help would be appreciated. Regards, Satyajit.
