在无服务器 yml 文件中创建 DynamoDB 表

Question

我将在 yml 文件中创建表。 当我写如下时，首先它是成功创建的。

  UsersTable:
  Type: AWS::DynamoDB::Table
  Properties:
    TableName: users
    AttributeDefinitions:
      - AttributeName: user_id
        AttributeType: S
    KeySchema:
      - AttributeName: user_id
        KeyType: HASH
    ProvisionedThroughput:
      ReadCapacityUnits: 5
      WriteCapacityUnits: 5

但我需要更多属性，所以我改变如下。

  UsersTable:
  Type: AWS::DynamoDB::Table
  Properties:
    TableName: users
    AttributeDefinitions:
      - AttributeName: user_id
        AttributeType: S
      - AttributeName: email_lower_case
        AttributeType: S
      - AttributeName: book_id
        AttributeType: S
      - AttributeName: book_amount
        AttributeType: S  
    KeySchema:
      - AttributeName: user_id
        KeyType: HASH
    ProvisionedThroughput:
      ReadCapacityUnits: 5
      WriteCapacityUnits: 5

但它显示这样的错误。

An error occurred: UsersTable - One or more parameter values were invalid: Number of attributes in KeySchema does not exactly match number of attributes defined in AttributeDefinitions

我不想使用其他 KeySchema。 是否可以创建这样的表？ 我不能使用不包含在任何索引中的属性创建表吗？

Answer 1

您必须在属性定义中包含键。

  UsersTable:
  Type: AWS::DynamoDB::Table
  Properties:
    TableName: users
    AttributeDefinitions:
      - AttributeName: user_id
        AttributeType: S

      - AttributeName: bitwage_user_id
        AttributeType: S
      - AttributeName: email_lower_case
        AttributeType: S
      - AttributeName: book_id
        AttributeType: S
      - AttributeName: book_amount
        AttributeType: S  
    KeySchema:
      - AttributeName: user_id
        KeyType: HASH
    ProvisionedThroughput:
      ReadCapacityUnits: 5
      WriteCapacityUnits: 5
