> | - In Spark 3.2, `TRANSFORM` operator can support
> `ArrayType/MapType/StructType` without Hive SerDe, in this mode, we use
> `StructsToJosn` to convert `ArrayType/MapType/StructType` column to `STRING`
> and use `JsonToStructs` to parse `STRING` to `ArrayType/MapType/StructType`.
> In Spark 3.1, Spark just support case `ArrayType/MapType/StructType` column
> as `STRING` but can't support parse `STRING` to
> `ArrayType/MapType/StructType` output columns.|
>
> StructToJosn -> StructToJson
