DynamoDB autoscaling with cloud scope

Following is the ClodFormation autoscaling policy for DynamoDB table. Hopefully this will give you some idea of ​​how to shape the policy script.

{
  "Type" : "AWS::ApplicationAutoScaling::ScalingPolicy",
  "Properties" : {
    "PolicyName" : "MyScalingPolicy",
    "PolicyType" : "TargetTrackingScaling",
    "ResourceId" : "arn:aws:dynamodb:us-east-1:123456789012:table/books_table",
    "ScalableDimension" : "dynamodb:table:WriteCapacityUnits",
    "ServiceNamespace" : "dynamodb",
    "TargetTrackingScalingPolicyConfiguration" : {
    "PredefinedMetricSpecification": {
            "PredefinedMetricType": "DynamoDBWriteCapacityUtilization"
        },
        "ScaleOutCooldown": 60,
        "ScaleInCooldown": 60,
        "TargetValue": 50.0
    }    
  }
}
