在 Cloudformation 中创建 DynamoDB table 失败

Question

我收到以下错误：

Property AttributeDefinitions is inconsistent with the KeySchema of the table and the secondary indexes

但我不确定这里出了什么问题。

  FeedbackTable: 
    Type: "AWS::DynamoDB::Table"
    Properties: 
      AttributeDefinitions: 
        - 
          AttributeName: "uuid"
          AttributeType: "S"
        - 
          AttributeName: "timestamp"
          AttributeType: "N"
        - 
          AttributeName: "pros"
          AttributeType: "S"
        - 
          AttributeName: "cons"
          AttributeType: "S"
        - 
          AttributeName: "comments"
          AttributeType: "S"
        -

Answer 1

您不需要在此处指定 DynamoDB table 的所有属性。 cloudformation 需要的只是键和索引属性的定义。

因此，如果您将 AttributeDefinition 减少为 uuid 和 timestamp，应该没问题（只要您没有二级索引）。

这里是 CloudFormation 文档中关于此主题的部分：

A list of attributes that describe the key schema for the table and indexes. Duplicates are allowed.
