scalingAdjustment
@Stability(Stable) public CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.Builder scalingAdjustment(Number scalingAdjustment) Sets the value ofCfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.getScalingAdjustment()
- Parameters:
scalingAdjustment
- The amount by which to scale in or scale out, based on the specifiedAdjustmentType
. This parameter is required. A positive value adds to the instance group's Amazon EC2 instance count while a negative number removes instances. IfAdjustmentType
is set toEXACT_CAPACITY
, the number should only be a positive integer. IfAdjustmentType
is set toPERCENT_CHANGE_IN_CAPACITY
, the value should express the percentage as an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.- Returns:
this
-
adjustmentType
@Stability(Stable) public CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.Builder adjustmentType(String adjustmentType) Sets the value ofCfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.getAdjustmentType()
- Parameters:
adjustmentType
- The way in which Amazon EC2 instances are added (ifScalingAdjustment
is a positive number) or terminated (ifScalingAdjustment
is a negative number) each time the scaling activity is triggered.CHANGE_IN_CAPACITY
is the default.CHANGE_IN_CAPACITY
indicates that the Amazon EC2 instance count increments or decrements byScalingAdjustment
, which should be expressed as an integer.PERCENT_CHANGE_IN_CAPACITY
indicates the instance count increments or decrements by the percentage specified byScalingAdjustment
, which should be expressed as an integer. For example, 20 indicates an increase in 20% increments of cluster capacity.EXACT_CAPACITY
indicates the scaling activity results in an instance group with the number of Amazon EC2 instances specified byScalingAdjustment
, which should be expressed as a positive integer.- Returns:
this
-
coolDown
@Stability(Stable) public CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.Builder coolDown(Number coolDown) - Parameters:
coolDown
- The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.- Returns:
this
-
