> DataWritableWriter is a class used to write Hive records to Parquet files. This class is getting all the information about how to parse a record, such as schema and object inspector, every time a record is written (or write() is called).
> We can make this class perform better by initializing some writers per data
> type once, and saving all object inspectors on each writer.
> The class expects that the next records written will have the same object inspectors and schema, so there is no need to have conditions for that. When a new schema is written, DataWritableWriter is created again by Parquet.
