Struct rusoto_emr::ScalingRule

pub struct ScalingRule {
    pub action: ScalingAction,
    pub description: Option<String>,
    pub name: String,
    pub trigger: ScalingTrigger,
}

A scale-in or scale-out rule that defines scaling activity, including the CloudWatch metric alarm that triggers activity, how EC2 instances are added or removed, and the periodicity of adjustments. The automatic scaling policy for an instance group can comprise one or more automatic scaling rules.

Fields

action: ScalingAction

The conditions that trigger an automatic scaling activity.

description: Option<String>

A friendly, more verbose description of the automatic scaling rule.

name: String

The name used to identify an automatic scaling rule. Rule names must be unique within a scaling policy.

trigger: ScalingTrigger

The CloudWatch alarm definition that determines when automatic scaling activity is triggered.
