[][src]Struct rusoto_emr::SimpleScalingPolicyConfiguration

pub struct SimpleScalingPolicyConfiguration {
    pub adjustment_type: Option<String>,
    pub cool_down: Option<i64>,
    pub scaling_adjustment: i64,
}

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.

Fields

adjustment_type: Option<String>

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 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 EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

cool_down: Option<i64>

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.

scaling_adjustment: i64

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 an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.
