amazon-dynamodb - 如何使用云形成更新 dynamodb 表

Question

如何使用云形成为现有 dynamodb 表启用“PointInTimeRecoverySpecification”。我尝试过如下:

Resources: 
  mytableenablerecovery: 
    Properties: 
       AttributeDefinitions: 
         - 
          AttributeName: ArtistId
          AttributeType: S
        KeySchema: 
          - 
          AttributeName: ArtistId
          KeyType: HASH
      PointInTimeRecoverySpecification: 
         PointInTimeRecoveryEnabled: true
      ProvisionedThroughput: 
        ReadCapacityUnits: "5"
        WriteCapacityUnits: "5"
      TableName: mytablename123
    Type: "AWS::DynamoDB::Table"

但如果新表不存在，则会创建新表，否则会抛出错误“mytablename123 已存在于堆栈 arn:aws:cloudformation:us-east-”

While the list is expanding , only some resource types currently support importing existing resources into CloudFormation

幸运的是，AWS::DynamoDB::Table目前是这些资源类型之一

要将这些支持的资源类型之一的现有资源导入 CloudFormation，必须使用更改集 as described here 导入它们。
