In this case, we need to be able to infer the schema with a `StructType` instead of a `MapType`. Therefore, this PR proposes adding an new configuration `spark.sql.pyspark.inferNestedDictAsStruct.enabled` to handle which type is used for inferring nested structs. - When `spark.sql....
we had to convert the data approriately. CSV files have a header with the field name, but not the type, so we must know in advance how to convert data. This could be done with a case class in Scala. We convert the scalars, when we have an array we just build a sequence (in t...
