public abstract class BaseScalableAttribute
extends software.constructs.Construct

(experimental) Represent an attribute for which autoscaling can be configured.

This class is basically a light wrapper around ScalableTarget, but with all methods protected instead of public so they can be selectively exposed and/or more specific versions of them can be exposed by derived classes for individual services support autoscaling.

Typical use cases:

• Hide away the PredefinedMetric enum for target tracking policies.
• Don't expose all scaling methods (for example Dynamo tables don't support Step Scaling, so the Dynamo subclass won't expose this method).
