Class SimpleScalingPolicyConfiguration

    • Constructor Detail

      • SimpleScalingPolicyConfiguration

        public SimpleScalingPolicyConfiguration()
    • Method Detail

      • setAdjustmentType

        public void setAdjustmentType(String adjustmentType)

        The way in which Amazon 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 Amazon 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 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 by ScalingAdjustment, which should be expressed as a positive integer.

        Parameters:
        adjustmentType - The way in which Amazon 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 Amazon 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 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 by ScalingAdjustment, which should be expressed as a positive integer.
