Wes McKinney commented on ARROW-3850:
-------------------------------------

Is StructType not supported yet? I know that Map is definitely not yet.

> It would be great to support MapType and StructType in Arrow so that PySpark can make use of it.

>  Quite often as in my use-case in Hive table cells are also complex types saved. Currently it's not possible to user the new {{[pandas_udf|https://spark.apache.org/docs/latest/api/python/pyspark.sql.html?highlight=explode#pyspark.sql.functions.pandas_udf]}} decorator which internally uses Arrow to generate a UDF an columns with complex types.
