   I suspect that writing a dataset while reading from another dataset might have issues. I don't see any options to set the number of open files on a dataset read.. I'm guessing the total number of open files should files being read + files being written..
   
   my_source_dataset = pyarrow.Dataset.dataset("original_csv_files")
   pyarrow.Dataset.write_dataset(my_source_dataset, base_dir = "parted_parquet")
   
   def dataset(source, schema=None, format=None, filesystem=None,
               partitioning=None, partition_base_dir=None,
               exclude_invalid_files=None, ignore_prefixes=None):
       """
       Open a dataset.
