使用SAM模板创建DynamoDB表时出错

Question

我想使用SAM模板创建DynamoDB表，而且我是SAM模板的新手。我对Hash和Range没有更好的想法这是我的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

这是我在创建表时得到的错误代码。

CREATE_FAILED       AWS::DynamoDB::Table        MyDynamoDBTable             Resource handler retur                                                               message: "1 validation

如有任何帮助，我们将不胜感激。

您正试图创建一个具有4个Range键的表。Dynamo只支持一个Partition和一个Range键。在继续之前，您应该先查看文档。

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
