範例 4：使用 CloudFormation 標記串流

您可以直接在 CloudFormation 範本中指定 DynamoDB Streams 上的標籤。串流標籤是在標準資料表的 StreamSpecification 屬性內定義，而在全域資料表的 ReplicaStreamSpecification 屬性內定義。

AWS::DynamoDB::Table

Resources:
  MyTable:
    Type: AWS::DynamoDB::Table
    Properties:
      TableName: MyTable
      AttributeDefinitions:
        - AttributeName: id
          AttributeType: S
      KeySchema:
        - AttributeName: id
          KeyType: HASH
      BillingMode: PAY_PER_REQUEST
      Tags:
        - Key: TableEnv
          Value: Production
      StreamSpecification:
        StreamViewType: NEW_AND_OLD_IMAGES
        Tags:
          - Key: StreamEnv
            Value: Production
          - Key: StreamTeam
            Value: Payments

AWS::DynamoDB::GlobalTable

Resources:
  MyGlobalTable:
    Type: AWS::DynamoDB::GlobalTable
    Properties:
      TableName: MyGlobalTable
      AttributeDefinitions:
        - AttributeName: id
          AttributeType: S
      KeySchema:
        - AttributeName: id
          KeyType: HASH
      BillingMode: PAY_PER_REQUEST
      StreamSpecification:
        StreamViewType: NEW_AND_OLD_IMAGES
      Replicas:
        - Region: us-east-1
          Tags:
            - Key: TableEnv
              Value: Production
          ReplicaStreamSpecification:
            Tags:
              - Key: StreamEnv
                Value: Production
              - Key: StreamTeam
                Value: Payments
        - Region: eu-west-1
          Tags:
            - Key: TableEnv
              Value: Production
          ReplicaStreamSpecification:
            Tags:
              - Key: StreamEnv
                Value: Production
              - Key: StreamTeam
                Value: Payments

除了明確的串流標籤之外，CloudFormation 也會將堆疊層級標籤傳播至串流。如果您的堆疊已設定標籤，這些標籤會自動套用至堆疊中的所有資源，包括串流。
