Reproduce the failure with pyarrow.read_table(read_dictionary=string_columns) followed by table.append(df) using a bucket transform. Inspect the bucket-transform handling for Dictionary (Int32, Utf8) arrays; done means dictionary-encoded columns can be appended without the unsupported-data-type error.
