 Review comment:
   This comment is relevant for PR review, but I think it's not necessary for 
readers of the code. I suggest we remove it. If we want to keep the names of 
positional arguments for readability, we can do:
    
   ```
   writer_schema=self._schema
   reader_schema=self._schema
   reader = avroio.DatumReader(     
           writer_schema, reader_schema)
   ```
