[jira] [Created] (ARROW-9881) Add support for dictionary type to arrow::read_csv

Dmitry Chigarev created ARROW-9881:
--------------------------------------

             Summary: 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


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)
