删除DynamoDB默认CloudWatch警报
我是DynamoDB的新手。在创建DynamoDB表的同时，我可以看到它还创建了一些CloudWatch警报，例如TargetTraking-TableXx-ProvisionedCapacityHigh。
因此，我的问题是我可以删除这些警报，因为它正在增加成本。我尝试过研究此事，但DINT找到了任何东西。我害怕删除此功能，因为我不确定AWS本身是否正在使用这些警报来进行DynamoDB维护，以及是否删除它们是否会以任何方式进行DynamoDB故障。
我还想知道，如果启用自动启动或为DynameDB表启用了按需启用这些警报，则在自动化的情况下进行扩展。
就我而言，我不使用自动升级或onDemand表，所以如果删除这些警报，那很好吗？
I am new to DynamoDB. While creating a dynamodb table I can see that it also creates some cloudwatch alarms like TargetTraking-TableXX--ProvisionedCapacityHigh.
So my question is can I delete these alarms as it is adding cost. I have tried researching on this but dint find anything. I am afraid to delete this because I am not sure if the AWS itself is using these alarms for the dynamodb maintenance and whether if I delete them will the dynamodb malfunction by any means.
I would also like to know if these alarms are used for scaling up and down in case of autoscaling been enabled or ondemand provisioning is enabled for the dynamodb table.
In my case I am not using autoscaling or ondemand tables so is it fine if I delete those alarms?

如果启用了自动化，则可以创建CloudWatch警报，以便为了配置表。按需表由AWS完全管理，我们为使用的费用付费。如果您不希望自动化，则可以删除警报或禁用警报。为了恢复更改，自动化的重新部署将重新创建警报。
注意：自动化创建4读和4个写入表。警报描述还说，请勿编辑或删除警报，因为它会影响自动化功能。
The Cloudwatch alarms gets created if autoscaling is enabled for provisioned tables. Whereas On-demand tables are fully managed by AWS and we pay for what we use. If you wish not to have autoscaling then it is ok to delete the alarms or disable them. To revert back the change re-deploy of autoscaling will re-create the alarms.
NOTE: Autoscaling creates 4 read and 4 writes table. The alarms description also says do not EDIT or DELETE the alarm as it affects the autoscaling functionality.
