How to use the phoenixdb.avatica.proto.requests_pb2.ColumnsRequest function in phoenixdb

def get_columns(self, connection_id, catalog=None, schemaPattern=None, tableNamePattern=None, columnNamePattern=None):
        request = requests_pb2.ColumnsRequest()
        request.connection_id = connection_id
        if catalog is not None:

        response_data = self._apply(request, 'ResultSetResponse')
        response = responses_pb2.ResultSetResponse()
        response.ParseFromString(response_data)
        return response
