Correct, this is something to be expected, see [type inference docs](https://arrow.apache.org/docs/cpp/csv.html#data-types). You can change the column type and disable type inference with `column_types` in [`pa.csv.ConvertOptions`](https://arrow.apache.org/docs/python/generated/pyarrow.csv.ConvertOptions.html#pyarrow-csv-convertoptions): ```python In [45]: convert_options=csv.ConvertOptions( ...: column_types={ ...: 'col1': pa.string(), ...: } ...: ) ...: with io.BytesIO(b'col1,col2\n"001","foo"\n"002","bar"') as buf: ...: tbl = csv.read_csv(buf, parse_options=pa.csv.ParseOptions(quote_char='"'), ...: convert_options=convert_options) ...: print(tbl) ...: pyarrow.Table col1: string col2: string ---- col1: [["001","002"]] col2: [["foo","bar"]] ``` -- This is an automated message from the Apache Git Service.
