Implements IConstruct, IDependable

A scalable sagemaker endpoint attribute.

Example

import * as sagemaker from '@aws-cdk/aws-sagemaker-alpha';

declare const model: sagemaker.Model;

const variantName = 'my-variant';
const endpointConfig = new sagemaker.EndpointConfig(this, 'EndpointConfig', {
  instanceProductionVariants: [
    {
      model: model,
      variantName: variantName,
    },
  ]
});

const endpoint = new sagemaker.Endpoint(this, 'Endpoint', { endpointConfig });
const productionVariant = endpoint.findInstanceProductionVariant(variantName);
const instanceCount = productionVariant.autoScaleInstanceCount({
  maxCapacity: 3
});
instanceCount.scaleOnInvocations('LimitRPS', {
  maxRequestsPerSecond: 30,
});
