// `AutoScalingPolicy` is a subproperty of `InstanceGroupConfig` .
//
// `AutoScalingPolicy` defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. For more information, see [Using Automatic Scaling in Amazon EMR](https://docs.aws.amazon.com//emr/latest/ManagementGuide/emr-automatic-scaling.html) in the *Amazon EMR Management Guide* .
//
// Example:
//   // The code below shows an example of how to instantiate this type.
//   // The values are placeholders you should change.
