Spark structured streaming kafka convert JSON without schema (infer schema)

Question

I read Spark Structured Streaming doesn\'t support schema inference for reading Kafka messages as JSON. Is there a way to retrieve schema the same as Spark Streaming does:

Answer 1

Taking Arnon's solution to the next step (since it's deprecated in spark's newer versions, and would require iterating the whole dataframe just for a type casting)

spark.read.json(df.as[String])

Anyways, as for now, it's still experimental.
