CfnScalingPolicy

The name of the scaling policy. 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.

The scaling policy type. The following policy types are supported: `TargetTrackingScaling` —Not supported for Amazon EMR `StepScaling` —Not supported for DynamoDB, Amazon Comprehend, Lambda, Amazon Keyspaces, Amazon MSK, Amazon ElastiCache, or Neptune. `PredictiveScaling` —Only supported for Amazon ECS

The predictive scaling policy configuration.

Example: `function:my-function:prod` or `function:my-function:1` . - Amazon Keyspaces table - The resource type is `table` and the unique identifier is the table name. Example: `keyspace/mykeyspace/table/mytable` . - 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` . - Amazon ElastiCache replication group - The resource type is `replication-group` and the unique identifier is the replication group name. Example: `replication-group/mycluster` . - Amazon ElastiCache cache cluster - The resource type is `cache-cluster` and the unique identifier is the cache cluster name. Example: `cache-cluster/mycluster` . - Neptune cluster - The resource type is `cluster` and the unique identifier is the cluster name. Example: `cluster:mycluster` . - SageMaker serverless endpoint - The resource type is `variant` and the unique identifier is the resource ID. Example: `endpoint/my-end-point/variant/KMeansClustering` . - SageMaker inference component - The resource type is `inference-component` and the unique identifier is the resource ID. Example: `inference-component/my-inference-component` . - Pool of WorkSpaces - The resource type is `workspacespool` and the unique identifier is the pool ID. Example: `workspacespool/wspool-123456` .

The scalable dimension. This string consists of the service namespace, resource type, and scaling property. - `ecs:service:DesiredCount` - The task count of an ECS service. - `elasticmapreduce:instancegroup:InstanceCount` - The instance count of an EMR Instance Group. - `ec2:spot-fleet-request:TargetCapacity` - The target capacity of a Spot Fleet. - `appstream:fleet:DesiredCapacity` - The capacity of an AppStream 2.0 fleet. - `dynamodb:table:ReadCapacityUnits` - The provisioned read capacity for a DynamoDB table. - `dynamodb:table:WriteCapacityUnits` - The provisioned write capacity for a DynamoDB table. - `dynamodb:index:ReadCapacityUnits` - The provisioned read capacity for a DynamoDB global secondary index. - `dynamodb:index:WriteCapacityUnits` - The provisioned write capacity for a DynamoDB global secondary index. - `rds:cluster:ReadReplicaCount` - The count of Aurora Replicas in an Aurora DB cluster. Available for Aurora MySQL-compatible edition and Aurora PostgreSQL-compatible edition. - `sagemaker:variant:DesiredInstanceCount` - The number of EC2 instances for a SageMaker model endpoint variant. - `custom-resource:ResourceType:Property` - The scalable dimension for a custom resource provided by your own application or service. - `comprehend:document-classifier-endpoint:DesiredInferenceUnits` - The number of inference units for an Amazon Comprehend document classification endpoint. - `comprehend:entity-recognizer-endpoint:DesiredInferenceUnits` - The number of inference units for an Amazon Comprehend entity recognizer endpoint. - `lambda:function:ProvisionedConcurrency` - The provisioned concurrency for a Lambda function. - `cassandra:table:ReadCapacityUnits` - The provisioned read capacity for an Amazon Keyspaces table. - `cassandra:table:WriteCapacityUnits` - The provisioned write capacity for an Amazon Keyspaces table. - `kafka:broker-storage:VolumeSize` - The provisioned volume size (in GiB) for brokers in an Amazon MSK cluster. - `elasticache:cache-cluster:Nodes` - The number of nodes for an Amazon ElastiCache cache cluster. - `elasticache:replication-group:NodeGroups` - The number of node groups for an Amazon ElastiCache replication group. - `elasticache:replication-group:Replicas` - The number of replicas per node group for an Amazon ElastiCache replication group. - `neptune:cluster:ReadReplicaCount` - The count of read replicas in an Amazon Neptune DB cluster. - `sagemaker:variant:DesiredProvisionedConcurrency` - The provisioned concurrency for a SageMaker serverless endpoint. - `sagemaker:inference-component:DesiredCopyCount` - The number of copies across an endpoint for a SageMaker inference component. - `workspaces:workspacespool:DesiredUserSessions` - The number of user sessions for the WorkSpaces in the pool.

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. > You must specify either the `ScalingTargetId` property, or the `ResourceId` , `ScalableDimension` , and `ServiceNamespace` properties, but not both.

The namespace of the AWS service that provides the resource, or a `custom-resource` .
