将 kinesis 流添加到 DynamoDB 全局表中

Question

我可以手动将 kinesis 流添加到每个区域的 DynamoDB 全局表中。我将流保留为特定于区域的流。使用 Cloudformation 模板添加时出现错误 “资源处理程序返回消息：”提供的请求无效：要启用 Kinesis Data Stream在 DynamoDBTable 中，流和表必须位于同一区域。"

我用于创作的 CFT 是，

如果我们可以为这两个区域附加特定于全局 DynamoDB 区域的运动流，那就太好了！

您尝试将相同的流 ARN 传递到两个区域，但这是行不通的。确保您将正确的流 ARN 传递到该给定区域的每个副本中：

      Replicas:
      - Region: !Ref AWSCurrentRegion
        KinesisStreamSpecification:
          StreamArn: <stream arn from  us-east-1 >    
        PointInTimeRecoverySpecification: 
          PointInTimeRecoveryEnabled: true        
      - Region: !Ref AWSReplicatedRegion
        KinesisStreamSpecification:
          StreamArn: <stream arn from  us-west-2 >     
        PointInTimeRecoverySpecification: 
          PointInTimeRecoveryEnabled: true
