@Generated(value="software.amazon.awssdk:codegen") public final class AutoScalingPolicy extends Object implements SdkPojo, Serializable, ToCopyableBuilder<AutoScalingPolicy.Builder,AutoScalingPolicy>
An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. An automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.

public final ScalingConstraints constraints()
The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.
public final boolean hasRules()
public final List<ScalingRule> rules()
The scale-in and scale-out rules that comprise the automatic scaling policy.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
You can use hasRules()
to see if a value was sent in this field.
