AWS DynamoDB/DAX ValueError: invalid literal for int() with base 10: '//test.<chars>.dax-clusters.<region>.amazonaws.com'

Question

我理解错误，但不确定为什么会发生。

    with AmazonDaxClient.resource(
            endpoint_url='daxs://test.<chars>.dax-clusters.<region>.amazonaws.com',
            region_name='<region>'
    ) as dynamodb:
        table = dynamodb.Table('<table_name>')

        stmt = """
    for i in range(3):
        table.get_item(Key={
            'id': str(i),
            'date': str(dt + relativedelta(days=i))
        })
        """

        timer = timeit.Timer(stmt, globals={'relativedelta': relativedelta, 'dt': date.today(), 'table': table})
        result = timer.repeat(repeat, n)

        return result

我只是想对我可用的不同数据库进行一些 read/write 次基准测试，但无法让 DAX 工作，而通过 boto3 与 DynamoDB 的标准连接似乎工作正常。任何输入都会非常有帮助

编辑：这是在 Lambda 上，这里是完整的错误消息：

  ]
}

最终将 endpoint_url 更改为 test.<chars>.dax-clusters.<region>.amazonaws.com。这最终导致错误告诉我集群端点出现故障。我最终不得不确保在 DAX 集群正在使用的安全组的 inbound/outbound 规则中指定了 Lambda 的安全组。
