amazon-web-services - Cloudformation DynamoDB 部署失败

Question

我有这个模板，非常简单。

DepartmentsTable:
  Type: AWS::DynamoDB::Table
  Properties:
    TableName: "Departments"
    AttributeDefinitions:
      - 
        AttributeName: "id"
        AttributeType: "S" 
      -
        AttributeName: "client_id"
        AttributeType: "S"
      -
        AttributeName: "department_name"
        AttributeType: "S"
    KeySchema:
      - 
        AttributeName: "id"
        KeyType: "HASH"
    BillingMode: "PAY_PER_REQUEST"

当我使用 3 个 attributeName 进行部署时，它不会部署。

当我将模板更改为具有单个属性时，它会进行部署。

任何想法

Answer 1

DynamoDB 是无模式的，因此在这方面您必须仅在创建时定义所需的键。

由于您仅使用 id 作为哈希键，因此这必须是您定义的唯一属性，因此您可以随意添加 client_id 和 department_name 当您插入您的元素时，CFN 不需要知道这些。这就是您收到异常的原因。

DepartmentsTable:
  Type: AWS::DynamoDB::Table
  Properties:
    TableName: "Departments"
    AttributeDefinitions:
      - 
        AttributeName: "id"
        AttributeType: "S" 
    KeySchema:
      - 
        AttributeName: "id"
        KeyType: "HASH"
    BillingMode: "PAY_PER_REQUEST"
