> Seems default of nullable is true ( https://arrow.apache.org/docs/python/generated/pyarrow.field.html#pyarrow.field ). What error does it report? And can you provide how to reproduce the error? ``` import random import pandas as pd import pyarrow as pa import pyarrow.dataset as ds schema = pa.schema([ pa.field('id', pa.string(), metadata={b"table_field": b"ID"}), pa.field('name', pa.string(), metadata={b"table_field": b"NAME"}), pa.field('age', pa.int8(), metadata={b"table_field": b"AGE"}) ]) data = { "id": [i for i in range(3)], "name": [None] * 3, "age": [random.randint(10, 30) for i in range(3)] } df = pd.DataFrame(data) print(df) table = pa.Table.from_pandas(df) file_path = 'test' ds.write_dataset(table, file_path, format='parquet', schema=schema) ``` -- This is an automated message from the Apache Git Service.
