- Source: [`aws-dynamodb/lib/scalable-attribute-api.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0/packages/aws-cdk-lib/aws-dynamodb/lib/scalable-attribute-api.ts#L6)

## Properties

- `env`: [ResourceEnvironment](/cdk/api/v2/docs/aws-cdk-lib.interfaces.ResourceEnvironment.html) (required) — The environment this resource belongs to.

  For resources that are created and managed in a Stack (those created by
  creating new class instances like `new Role()`, `new Bucket()`, etc.), this
  is always the same as the environment of the stack they belong to.

  For referenced resources (those obtained from referencing methods like
  `Role.fromRoleArn()`, `Bucket.fromBucketName()`, etc.), they might be
  different than the stack they were imported into.

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) (required) — The tree node.

- `scalableTargetRef`: [ScalableTargetReference](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_applicationautoscaling.ScalableTargetReference.html) (required) — A reference to a ScalableTarget resource.

## Methods

- `scaleOnSchedule(id: string, actions: ScalingSchedule): void` — Add scheduled scaling for this scaling attribute.

- `scaleOnUtilization(props: UtilizationScalingProps): void` — Scale out or in to keep utilization at a given level.

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.

  **Parameters**

  - `mixins` — The mixins to apply.

  **Returns:** This construct for chaining
