/**
 * <p>Extends an existing training plan by purchasing an extension offering. This allows you to add additional compute capacity time to your training plan without creating a new plan or reconfiguring your workloads.</p> <p>To find available extension offerings, use the <code> <a href="https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_SearchTrainingPlanOfferings.html">SearchTrainingPlanOfferings</a> </code> API with the <code>TrainingPlanArn</code> parameter.</p> <p>To view the history of extensions for a training plan, use the <code> <a href="https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_DescribeTrainingPlanExtensionHistory.html">DescribeTrainingPlanExtensionHistory</a> </code> API.</p>

 * const input = { // ExtendTrainingPlanRequest

 * };
 * const command = new ExtendTrainingPlanCommand(input);
 * const response = await client.send(command);
 * // { // ExtendTrainingPlanResponse
