How to use the datasketch.storage.RedisBuffer function in datasketch

def __init__(self, config, name=None):
            self.config = config
            self._buffer_size = 50000
            redis_param = self._parse_config(self.config['redis'])
            self._redis = redis.Redis(**redis_param)
            self._buffer = RedisBuffer(self._redis.connection_pool,
                                       self._redis.response_callbacks,
                                       transaction=True,
                                       buffer_size=self._buffer_size)
            if name is None:
                name = _random_name(11)
            self._name = name

def execute_command(self, *args, **kwargs):
            if len(self.command_stack) >= self._buffer_size:
                self.execute()
            super(RedisBuffer, self).execute_command(*args, **kwargs)
