import pyarrow.fs as pafs
import pyarrow.parquet as pq

filesystem = pafs.LocalFileSystem()
subtree_filesystem = pafs.SubTreeFileSystem('C:\\', filesystem)

in_path = 'Users\\westpace\\in.parquet'
out_path = 'Users\\westpace\\out.parquet'

table = pq.read_table(in_path, filesystem=subtree_filesystem)
print(f'Read in {table.num_rows} rows')
pq.write_table(table, out_path, filesystem=subtree_filesystem)
# pq.write_to_dataset(table, out_path, filesystem=subtree_filesystem)
