无法在 DynamoDB 中创建计费模式设置为 PAY_PER_REQUEST 的表

Question

我目前正在使用 AWS cli 在 DynamoDB 中创建一个表。我正在使用的命令是

aws dynamodb create-table --cli-input-json file://.feature_promotions-dynamodb.json  --endpoint-url http://localhost:8000

根据 的文档create-table，我应该能够将计费模式设置为，而PAY_PER_REQUEST不必设置预配置的吞吐量，但每次运行命令时我都会收到以下错误：

An error occurred (ValidationException) when calling the CreateTable operation: No provisioned throughput specified for the table

我awscli昨天升级到

aws-cli/1.16.90 Python/3.7.2 Darwin/18.2.0 botocore/1.12.80

除此之外，我不知道如何解决它。目前我的解决方法是仅创建具有预配置吞吐量的表，然后转到控制台进行更改，但这似乎没有必要。最终，我希望能够在 bash 脚本中运行此命令，而不必稍后修复 AWS 控制台中的表设置。

下面是我在命令中加载的 JSON 文件create-table。"BillingMode": "PAY_PER_REQUEST"属性和值是在之后设置的"AttributeDefinition"，我希望它能够正常工作而不会出现任何错误。如果我删除计费模式行，并将以下属性添加到文件中

"ProvisionedThroughput": {
        "ReadCapacityUnits": 1,
        "WriteCapacityUnits": 1
      }

它创建的表没有任何错误。

我究竟做错了什么？

您只能在表或 GSI 上使用"BillingMode": "PAY_PER_REQUEST"其中之一。ProvisionedThroughput您需要删除ProvisionedThroughput任何按需资源。

编辑：要明确的是，您不能使用ProvisionedThroughput按需表的索引。要解决此问题，只需删除 的所有实例即可ProvisionedThroughput。您的索引也将按需提供。
