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

基于create-table的文档，我应该能够将计费方式设置为PAY_PER_REQUEST，而不必设置预配置的吞吐量，但是每次运行命令时，我都会得到以下错误：

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

我昨天将awscli升级到了

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

除此之外，我对如何解决它没有想法。我目前的解决方法是仅使用预配置的吞吐量创建表，然后转到控制台进行更改，但这似乎是不必要的。最终，我希望能够在bash脚本中运行此命令，而不必稍后在AWS控制台中修复表设置。

以下是我在create-table命令中加载的JSON文件。 "BillingMode": "PAY_PER_REQUEST"的属性和值是在"AttributeDefinition"之后设置的，我希望它可以正常工作。如果我删除结算方式行，然后将以下属性添加到文件中

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

它创建表没有任何错误。

我在做什么错了？

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

编辑：为清楚起见，您不能在按需表的索引上使用ProvisionedThroughput。要解决此问题，只需删除ProvisionedThroughput的所有实例。您的索引也将随需应变。
