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.
