[jira] [Created] (PARQUET-1962) Filtering dictionary data types using dplyr in Arrow package

Soumya Ranjan Prusty created PARQUET-1962:
---------------------------------------------

             Summary: Filtering dictionary data types using dplyr in Arrow package
                 Key: PARQUET-1962
                 URL: https://issues.apache.org/jira/browse/PARQUET-1962
             Project: Parquet
          Issue Type: Bug
            Reporter: Soumya Ranjan Prusty


Is there any way where we can filter the dictionary data types using dplyr. Below is the example for illustration 

test %>% dplyr::filter(cols %in% c("A","B","C") %>collect(). It gives me following error

Error in dataset___Scanner__ToTable(self) :   NotImplemented: Function is_in has no kernel matching input types (array[dictionary<values=string, indices=int32, ordered=0>])

Here cols is dictionary type value
