The upper and lower EC2 instance limits for an automatic scaling policy.

Automatic scaling activities triggered by automatic scaling rules will not cause an instance group to grow above or below these limits.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_stepfunctions_tasks as stepfunctions_tasks } from 'aws-cdk-lib';
const scalingConstraintsProperty: stepfunctions_tasks.EmrCreateCluster.ScalingConstraintsProperty = {
  maxCapacity: 123,
  minCapacity: 123,
};

Properties

Name	Type	Description
maxCapacity	number	The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow.
minCapacity	number	The lower boundary of EC2 instances in an instance group below which scaling activities are not allowed to shrink.

---

maxCapacity

Type: number

The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow.

Scale-out activities will not add instances beyond this boundary.

---

minCapacity

Type: number

The lower boundary of EC2 instances in an instance group below which scaling activities are not allowed to shrink.

Scale-in activities will not terminate instances below this boundary.
