DynamoDB.create_table erroring with `ArgumentError: no such member :billing_mode`

Question

我正在尝试使用 DynamoDB 客户端通过 aws-sdk(2.11.31) 创建一个新的 table；

        new_table_definition = {
          attribute_definitions: [
            {
              attribute_name: 'user',
              attribute_type: 'S'
            },
            {
              attribute_name: 'timestamp',
              attribute_type: 'N'
            },
            {
              attribute_name: 'uuid',
              attribute_type: 'S'
            }
          ],
          key_schema: [
            {
              attribute_name: 'uuid',
              key_type: 'HASH'
            },
            {
              attribute_name: 'timestamp',
              key_type: 'RANGE'
            }
          ],
          global_secondary_indexes: [
            {
              index_name: 'user-timestamp-index',
              key_schema: [
                {
                  attribute_name: 'user',
                  key_type: 'HASH'
                },
                {
                  attribute_name: 'timestamp',
                  key_type: 'RANGE'
                }
              ],
              projection: {
                projection_type: 'KEYS_ONLY'
              },
              provisioned_throughput: {
                read_capacity_units: 0,
                write_capacity_units: 0,
              }
            }
          ],
          billing_mode: "PAY_PER_REQUEST",
          provisioned_throughput: {
            read_capacity_units: 0,
            write_capacity_units: 0
          },
          table_name: "A_NEW_TABLE"
        }
        Dynamo::Table.create(new_table_definition)

但是我收到以下错误： ArgumentError: no such member :billing_mode

据我所知，这是 sdk v2 文档中描述的计费模式的正确密钥和格式。删除计费模式会创建 table 罚款，但我随后被迫进入 AWS 控制台以手动将其更改为按需模式。

我特别遇到的问题是 gem 版本。好像不支持billing_mode.

我在测试较新版本时还发现的另一个问题实际上是同时发送 billing_mode 和 provisioned_throughput 值。这是 either/or 的情况。

If read/write capacity mode is PAY_PER_REQUEST the value is set to 0. 本文档中的这一行造成了混淆 https://docs.aws.amazon.com/sdk-for-ruby/v2/api/Aws/DynamoDB/Types/ProvisionedThroughput.html

看到这里它告诉你不要通过它： https://docs.aws.amazon.com/sdk-for-ruby/v2/api/Aws/DynamoDB/Client.html#create_table-instance_method
