Summary: [C++] Add support for dictionary type to arrow::read_csv (was: Add support for dictionary type to arrow::read_csv)
> [C++] Add support for dictionary type to arrow::read_csv
> --------------------------------------------------------

> Key: ARROW-9881
> URL: https://issues.apache.org/jira/browse/ARROW-9881
> Project: Apache Arrow
> Issue Type: Improvement
> Reporter: Dmitry Chigarev
> Priority: Minor
>
> For now, the only way to encode column with dict-encoding is to set {{auto_dict_encode = True}} at {{arrow::csv}}{{::}}{{ConvertOptions}}
> However, users should have the ability to specify column type as dict explicitly via {{column_types}} parameter. (Currently it is raising an exception that dict type is not supported)
