@Stability(Stable) public static interface EmrCreateCluster.ScalingTriggerProperty extends software.amazon.jsii.JsiiSerializable
The conditions that trigger an automatic scaling activity and the definition of a CloudWatch metric alarm.

When the defined alarm conditions are met along with other trigger parameters, scaling activity begins.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
