> I had a program to read some csv files (a few million rows each, 9 columns),
> and converted with:
> {code}
> import os
> import pandas as pd
> import pyarrow.parquet as pq
> import pyarrow
> def to_parquet(output_file, csv_file):
> df = pd.read_csv(csv_file)
> df['gecco_variant'] = [ v.lstrip('0') for v in df['gecco_variant']]
> table = pyarrow.Table.from_pandas(df)
> pq.write_table(table, output_file)
> {code}
> The first csv file would always complete, but python would hang on the second
> or third file, and sometimes on a much later file.
