> When converting a table in which one of the column's type is of DictionaryType (values=int32, indices=int32, ordered=0) the conversion to pandas DataFrame fails with:
> NotImplementedError: dictionary<values=int32, indices=int32, ordered=0>
> The dictionary has this conversion not implmented yet.
> This DictionaryType is used as type when using one of the columns (Int64) as one of the parquet's dataset partition columns.
