Review Comment:
```
import pyarrow as pa
import pyarrow.parquet as pq
arr = pa.array([[("a" * 2**30, 1)]], type = pa.map_(pa.string(), pa.int32()))
arr = pa.chunked_array([arr, arr])
tab = pa.table({ "arr": arr, "dict_arr": arr})
pq.write_table(tab, "test.parquet", compression='BROTLI',
use_dictionary=['dict_arr'])
```
I have written the above script, but I am not sure it's doing what it's
supposed to do. Is there a way to verify it? `parquet-tools inspect` does not
tell me much.
