Method Summary

Modifier and Type	Method and Description
SimpleScalingPolicyConfiguration.Builder	adjustmentType(AdjustmentType adjustmentType) The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered.
SimpleScalingPolicyConfiguration.Builder	adjustmentType(String adjustmentType) The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered.
SimpleScalingPolicyConfiguration.Builder	coolDown(Integer coolDown) The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start.
SimpleScalingPolicyConfiguration.Builder	scalingAdjustment(Integer scalingAdjustment) The amount by which to scale in or scale out, based on the specified AdjustmentType.

Method Detail

adjustmentType

SimpleScalingPolicyConfiguration.Builder adjustmentType(String adjustmentType)

The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as a decimal. For example, 0.20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

Parameters:

adjustmentType - The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as a decimal. For example, 0.20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

Returns:

Returns a reference to this object so that method calls can be chained together.

adjustmentType

SimpleScalingPolicyConfiguration.Builder adjustmentType(AdjustmentType adjustmentType)

The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as a decimal. For example, 0.20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

Parameters:

CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer.

scalingAdjustment

SimpleScalingPolicyConfiguration.Builder scalingAdjustment(Integer scalingAdjustment)

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY, the value should express the percentage as a decimal. For example, -0.20 indicates a decrease in 20% increments of cluster capacity.

Parameters:

scalingAdjustment - The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY, the value should express the percentage as a decimal. For example, -0.20 indicates a decrease in 20% increments of cluster capacity.

Returns:

Returns a reference to this object so that method calls can be chained together.

coolDown

SimpleScalingPolicyConfiguration.Builder coolDown(Integer 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.

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:

Returns a reference to this object so that method calls can be chained together.
