PropertyDefinition不一致

Question

我在 cloudformation UI 中使用以下模板来创建 dynamoDB table。我想创建一个 table PrimaryKey 作为 ID 和 sortKey 作为值

{
  "AWSTemplateFormatVersion" : "2010-09-09",

  "Description" : "DB Description",

  "Resources" : {
    "TableName" : {
      "Type" : "AWS::DynamoDB::Table",
      "Properties" : {
        "AttributeDefinitions": [ { 
          "AttributeName" : "ID",
          "AttributeType" : "S"
        }, { 
          "AttributeName" : "Value",
          "AttributeType" : "S"
        } ],
        "KeySchema": [
          { 
            "AttributeName": "ID", 
            "KeyType": "HASH"
          }
        ]                
      },
      "TableName": "TableName"
    }
  }
}

在 CF UI 上，我单击新堆栈，指向本地计算机中的 template 文件，为堆栈命名并单击下一步。一段时间后，我收到错误提示 属性 AttributeDefinitions is inconsistent with the KeySchema of the table and the secondary indexes

Answer 1

问题是 Resources.Properties.AttributeDefinitions 键必须仅定义用于索引或键的列。换句话说，Resources.Properties.AttributeDefinitions 中的键必须匹配 Resources.Properties.KeySchema.

中定义的相同键

AWS 文档：

AttributeDefinitions: A list of AttributeName and AttributeType objects that describe the key schema for the table and indexes.

因此生成的模板将如下所示：

{
  "AWSTemplateFormatVersion" : "2010-09-09",

  "Description" : "DB Description",

  "Resources" : {
    "TableName" : {
    "Type" : "AWS::DynamoDB::Table",
    "Properties" : {
      "AttributeDefinitions": [ { 
        "AttributeName" : "ID",
        "AttributeType" : "S"
      } ],
      "ProvisionedThroughput":{
        "ReadCapacityUnits" : 1,
        "WriteCapacityUnits" : 1
      },
      "KeySchema": [
        { 
          "AttributeName": "ID", 
          "KeyType": "HASH"
        }
       ] ,               
      "TableName": "table5"
    }
   }
  }
}

Answer 2

在 AttributeDefinitions 中，您只需定义分区键和范围键，而不是其他属性。

AttributeDefinitions 和 KeySchema 中的属性数量应该匹配并且应该完全相同。

Answer 3

接受的答案在错误原因上是正确的，但您说您希望排序键是 Value。所以你应该改变你的 CloudFormation 以包括：

{
  "AWSTemplateFormatVersion" : "2010-09-09",

  "Description" : "DB Description",

  "Resources" : {
    "TableName" : {
      "Type" : "AWS::DynamoDB::Table",
      "Properties" : {
        "AttributeDefinitions": [ { 
          "AttributeName" : "ID",
          "AttributeType" : "S"
        }, { 
          "AttributeName" : "Value",
          "AttributeType" : "S"
        } ],
        "KeySchema": [
          { 
            "AttributeName": "ID", 
            "KeyType": "HASH"
          },
          { 
            "AttributeName": "Value", 
            "KeyType": "RANGE"
          }
        ]                
      },
      "TableName": "TableName"
    }
  }
}
