Overview

Name	`scaling_policies`
Type	Resource
Description	The ``AWS::ApplicationAutoScaling::ScalingPolicy`` resource defines a scaling policy that Application Auto Scaling uses to adjust the capacity of a scalable target. For more information, see [Target tracking scaling policies](https://docs.aws.amazon.com/autoscaling/application/userguide/application-auto-scaling-target-tracking.html) and [Step scaling policies](https://docs.aws.amazon.com/autoscaling/application/userguide/application-auto-scaling-step-scaling-policies.html) in the Application Auto Scaling User Guide.
Id	`awscc.applicationautoscaling.scaling_policies`

Fields

Name	Datatype	Description
`policy_type`	`string`	The scaling policy type.<br />The following policy types are supported: <br />``TargetTrackingScaling``—Not supported for Amazon EMR<br />``StepScaling``—Not supported for DynamoDB, Amazon Comprehend, Lambda, Amazon Keyspaces, Amazon MSK, Amazon ElastiCache, or Neptune.<br />``PredictiveScaling``—Only supported for Amazon ECS
`resource_id`	`string`	The identifier of the resource associated with the scaling policy. This string consists of the resource type and unique identifier.<br />+ ECS service - The resource type is ``service`` and the unique identifier is the cluster name and service name. Example: ``service/my-cluster/my-service``.<br />+ Spot Fleet - The resource type is ``spot-fleet-request`` and the unique identifier is the Spot Fleet request ID. Example: ``spot-fleet-request/sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE``.<br />+ EMR cluster - The resource type is ``instancegroup`` and the unique identifier is the cluster ID and instance group ID. Example: ``instancegroup/j-2EEZNYKUA1NTV/ig-1791Y4E1L8YI0``.<br />+ AppStream 2.0 fleet - The resource type is ``fleet`` and the unique identifier is the fleet name. Example: ``fleet/sample-fleet``.<br />+ DynamoDB table - The resource type is ``table`` and the unique identifier is the table name. Example: ``table/my-table``.<br />+ DynamoDB global secondary index - The resource type is ``index`` and the unique identifier is the index name. Example: ``table/my-table/index/my-table-index``.<br />+ Aurora DB cluster - The resource type is ``cluster`` and the unique identifier is the cluster name. Example: ``cluster:my-db-cluster``.<br />+ SageMaker endpoint variant - The resource type is ``variant`` and the unique identifier is the resource ID. Example: ``endpoint/my-end-point/variant/KMeansClustering``.<br />+ Custom resources are not supported with a resource type. This parameter must specify the ``OutputValue`` from the CloudFormation template stack used to access the resources. The unique identifier is defined by the service provider. More information is available in our [GitHub repository](https://docs.aws.amazon.com/https://github.com/aws/aws-auto-scaling-custom-resource).<br />+ Amazon Comprehend document classification endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example: ``arn:aws:comprehend:us-west-2:123456789012:document-classifier-endpoint/EXAMPLE``.<br />+ Amazon Comprehend entity recognizer endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example: ``arn:aws:comprehend:us-west-2:123456789012:entity-recognizer-endpoint/EXAMPLE``.<br />+ Lambda provisioned concurrency - The resource type is ``function`` and the unique identifier is the function name with a function version or alias name suffix that is not ``$LATEST``. Example: ``function:my-function:prod`` or ``function:my-function:1``.<br />+ Amazon Keyspaces table - The resource type is ``table`` and the unique identifier is the table name. Example: ``keyspace/mykeyspace/table/mytable``.<br />+ Amazon MSK cluster - The resource type and unique identifier are specified using the cluster ARN. Example: ``arn:aws:kafka:us-east-1:123456789012:cluster/demo-cluster-1/6357e0b2-0e6a-4b86-a0b4-70df934c2e31-5``.<br />+ Amazon ElastiCache replication group - The resource type is ``replication-group`` and the unique identifier is the replication group name. Example: ``replication-group/mycluster``.<br />+ Amazon ElastiCache cache cluster - The resource type is ``cache-cluster`` and the unique identifier is the cache cluster name. Example: ``cache-cluster/mycluster``.<br />+ Neptune cluster - The resource type is ``cluster`` and the unique identifier is the cluster name. Example: ``cluster:mycluster``.<br />+ SageMaker serverless endpoint - The resource type is ``variant`` and the unique identifier is the resource ID. Example: ``endpoint/my-end-point/variant/KMeansClustering``.<br />+ SageMaker inference component - The resource type is ``inference-component`` and the unique identifier is the resource ID. Example: ``inference-component/my-inference-component``.<br />+ Pool of WorkSpaces - The resource type is ``workspacespool`` and the unique identifier is the pool ID. Example: ``workspacespool/wspool-123456``.
`scaling_target_id`	`string`	The CloudFormation-generated ID of an Application Auto Scaling scalable target. For more information about the ID, see the Return Value section of the ``AWS::ApplicationAutoScaling::ScalableTarget`` resource.<br />You must specify either the ``ScalingTargetId`` property, or the ``ResourceId``, ``ScalableDimension``, and ``ServiceNamespace`` properties, but not both.
`policy_name`	`string`	The name of the scaling policy.<br />Updates to the name of a target tracking scaling policy are not supported, unless you also update the metric used for scaling. To change only a target tracking scaling policy's name, first delete the policy by removing the existing ``AWS::ApplicationAutoScaling::ScalingPolicy`` resource from the template and updating the stack. Then, recreate the resource with the same settings and a different name.
`service_namespace`	`string`	The namespace of the AWS service that provides the resource, or a ``custom-resource``.
`scalable_dimension`	`string`	The scalable dimension. This string consists of the service namespace, resource type, and scaling property.<br />+ ``ecs:service:DesiredCount`` - The task count of an ECS service.<br />+ ``elasticmapreduce:instancegroup:InstanceCount`` - The instance count of an EMR Instance Group.<br />+ ``ec2:spot-fleet-request:TargetCapacity`` - The target capacity of a Spot Fleet.<br />+ ``appstream:fleet:DesiredCapacity`` - The capacity of an AppStream 2.0 fleet.<br />+ ``dynamodb:table:ReadCapacityUnits`` - The provisioned read capacity for a DynamoDB table.<br />+ ``dynamodb:table:WriteCapacityUnits`` - The provisioned write capacity for a DynamoDB table.<br />+ ``dynamodb:index:ReadCapacityUnits`` - The provisioned read capacity for a DynamoDB global secondary index.<br />+ ``dynamodb:index:WriteCapacityUnits`` - The provisioned write capacity for a DynamoDB global secondary index.<br />+ ``rds:cluster:ReadReplicaCount`` - The count of Aurora Replicas in an Aurora DB cluster.
