Interface EmrCreateCluster.ScalingActionProperty

All Superinterfaces:

software.amazon.jsii.JsiiSerializable

All Known Implementing Classes:

EmrCreateCluster.ScalingActionProperty.Jsii$Proxy

Enclosing class:

EmrCreateCluster

@Stability(Stable)
public static interface EmrCreateCluster.ScalingActionProperty
extends software.amazon.jsii.JsiiSerializable

The type of adjustment the automatic scaling activity makes when triggered, and the periodicity of the adjustment.

And an automatic scaling configuration, which describes how the policy adds or removes instances, the cooldown period, and the number of EC2 instances that will be added each time the CloudWatch metric alarm condition is satisfied.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.stepfunctions.tasks.*;
 ScalingActionProperty scalingActionProperty = ScalingActionProperty.builder()
         .simpleScalingPolicyConfiguration(SimpleScalingPolicyConfigurationProperty.builder()
                 .scalingAdjustment(123)
                 // the properties below are optional
                 .adjustmentType(EmrCreateCluster.getScalingAdjustmentType().CHANGE_IN_CAPACITY)
                 .coolDown(123)
                 .build())
         // the properties below are optional
         .market(EmrCreateCluster.getInstanceMarket().ON_DEMAND)
         .build();
