alippai opened a new issue, #43210: URL: https://github.com/apache/arrow/issues/43210
### Describe the bug, including details regarding any error messages, version, and platform. The `column_types` parameter of the `pyarrow.csv.ConvertOptions` may ignore the field nullability in some cases. A `parsed_table.cast(schema)` after the read fixes the problem (which also implies there was no null data). I couldn't come up with a small example yet. ### Component(s) Python -- This is an automated message from the Apache Git Service.
