You can convert from Avro to Spark format, but you need to somehow get the Avro schema. The key and value are not really different in most cases.

Hi, @cerveada I did it but the the fame i get is with column name from_avro(kafka_binary_key) and the value in this column is 1. So its look like the key "id" is missing from some reason. I expected to see column id and value 1

Couldn't you just rename the column name to 'key' then?
