amazon-web-services - 使用 SAM 模板创建 DynamoDB 表时出现错误

Question

我想使用 SAM 模板创建 DynamoDB 表，并且我是 SAM 模板的新手。我对哈希和范围没有更好的了解这是我的 DynamoDB 模板部分

  MyDynamoDBTable:
    Type: AWS::DynamoDB::Table
    DeletionPolicy: Retain
    Properties:
      TableName: customerInformations
      AttributeDefinitions:
        - AttributeName: phoneNumber
          AttributeType: S
        - AttributeName: firstName
          AttributeType: S
        - AttributeName: lastName
          AttributeType: S
        - AttributeName: address
          AttributeType: S
        - AttributeName: email
          AttributeType: S
      KeySchema:
        - AttributeName: phoneNumber
          KeyType: HASH
        - AttributeName: firstName
          KeyType: RANGE
        - AttributeName: lastName
          KeyType: RANGE
        - AttributeName: address
          KeyType: RANGE
        - AttributeName: email
          KeyType: RANGE

这是我在创建表时收到的错误代码。

任何帮助将不胜感激。

Answer 1

您正在尝试创建一个包含 4 个范围键的表。 Dynamo 仅支持 1 个 Partition 和 1 个 Range key。您应该看看documentation在继续之前。

示例解决方案:

  MyDynamoDBTable:
    Type: AWS::DynamoDB::Table
    DeletionPolicy: Retain
    Properties:
      TableName: customerInformations
      AttributeDefinitions:
        - AttributeName: phoneNumber
          AttributeType: S
        - AttributeName: firstName
          AttributeType: S
      KeySchema:
        - AttributeName: phoneNumber
          KeyType: HASH
        - AttributeName: firstName
          KeyType: RANGE
