Creates or updates a scheduled action for an Application Auto Scaling scalable target.
applicationautoscaling_put_scheduled_action(ServiceNamespace, Schedule,
ScheduledActionName, ResourceId, ScalableDimension, StartTime, EndTime,
ScalableTargetAction)[required] The namespace of the AWS service that provides the resource or
custom-resource for a resource provided by your own application or
service. For more information, see AWS Service Namespaces
in the Amazon Web Services General Reference.
The schedule for this action. The following formats are supported:
At expressions -
"at(<i>yyyy</i>-<i>mm</i>-<i>dd</i>T<i>hh</i>:<i>mm</i>:<i>ss</i>)"
Rate expressions - "rate(<i>value</i> <i>unit</i>)"
Cron expressions - "cron(<i>fields</i>)"
At expressions are useful for one-time schedules. Specify the time, in UTC.
For rate expressions, value is a positive integer and unit is
minute \| minutes \| hour \| hours \| day \| days.
For more information about cron expressions, see Cron Expressions in the Amazon CloudWatch Events User Guide.
[required] The name of the scheduled action.
[required] The identifier of the resource associated with the scheduled action. This string consists of the resource type and unique identifier.
ECS service - The resource type is service and the unique
identifier is the cluster name and service name. Example:
service/default/sample-webapp.
Spot fleet request - 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.
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.
AppStream 2.0 fleet - The resource type is fleet and the unique
identifier is the fleet name. Example: fleet/sample-fleet.
DynamoDB table - The resource type is table and the unique
identifier is the resource ID. Example: table/my-table.
DynamoDB global secondary index - The resource type is index and
the unique identifier is the resource ID. Example:
table/my-table/index/my-table-index.
Aurora DB cluster - The resource type is cluster and the unique
identifier is the cluster name. Example: cluster:my-db-cluster.
Amazon SageMaker endpoint variants - The resource type is variant
and the unique identifier is the resource ID. Example:
endpoint/my-end-point/variant/KMeansClustering.
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.
[required] The scalable dimension. This string consists of the service namespace, resource type, and scaling property.
ecs:service:DesiredCount - The desired task count of an ECS
service.
ec2:spot-fleet-request:TargetCapacity - The target capacity of a
Spot fleet request.
elasticmapreduce:instancegroup:InstanceCount - The instance count
of an EMR Instance Group.
appstream:fleet:DesiredCapacity - The desired 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 an Amazon SageMaker model endpoint variant.
custom-resource:ResourceType:Property - The scalable dimension for
a custom resource provided by your own application or service.
The date and time for the scheduled action to start.
The date and time for the scheduled action to end.
The new minimum and maximum capacity. You can set both values or just one. During the scheduled time, if the current capacity is below the minimum capacity, Application Auto Scaling scales out to the minimum capacity. If the current capacity is above the maximum capacity, Application Auto Scaling scales in to the maximum capacity.

Each scalable target is identified by a service namespace, resource ID, and scalable dimension. A scheduled action applies to the scalable target identified by those three attributes. You cannot create a scheduled action until you have registered the resource as a scalable target using RegisterScalableTarget.
To update an action, specify its name and the parameters that you want to change. If you don't specify start and end times, the old values are deleted. Any other parameters that you don't specify are not changed by this update request.
You can view the scheduled actions using DescribeScheduledActions. If you are no longer using a scheduled action, you can delete it using DeleteScheduledAction.
Learn more about how to work with scheduled actions in the Application Auto Scaling User Guide.
