# ScaleInPolicyProperty

Specifies how the endpoint releases instances when managed instance scaling scales in.

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_sagemaker as sagemaker } from 'aws-cdk-lib';
const scaleInPolicyProperty: sagemaker.CfnEndpointConfig.ScaleInPolicyProperty = {
  strategy: 'strategy',

  // the properties below are optional
  cooldownInMinutes: 123,
  maximumStepSize: 123,
};
```

## Properties

- `cooldownInMinutes`: number — The cooldown period, in minutes, after the last endpoint operation before the endpoint evaluates consolidation scale-in opportunities.

  Valid values are 5 to 1440. The default is 20.

- `maximumStepSize`: number — The maximum number of instances that the endpoint can terminate at a time during a consolidation scale-in operation.

  Valid values are 1 to 100. The default is 1.

- `strategy`: string (required) — The strategy for scaling in instances.

  IDLE_RELEASE releases instances that have no hosted inference component copies. CONSOLIDATION consolidates inference component copies onto fewer instances to release more instances.
