-------------------------------------
Summary: pyarrow.csv.read_csv: Ability to not infer column types.
Key: ARROW-5811
URL: https://issues.apache.org/jira/browse/ARROW-5811
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Affects Versions: 0.13.0
Environment: Ubuntu Xenial
Reporter: Bogdan Klichuk
I'm trying to read CSV as is. All columns as strings. I don't know the schema
of these CSVs and they will vary as they are provided by user.
Right now i'm using pandas.read_csv(dtype=str) which works great, but since
final destination of these CSVs are parquet files it seems like much more
efficient to use pyarrow.csv.read_csv in future, as soon as this becomes
available :)
I tried things like
`pyarrow.csv.read_csv(convert_types=ConvertOptions(columns_types=defaultdict(lambda:
'string')))` but it doesn't work.
Maybe I just didnt' find something that already exists? :)
