• "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.

Valid values are: "ecs:service:DesiredCount", "ec2:spot-fleet-request:TargetCapacity", "elasticmapreduce:instancegroup:InstanceCount", "appstream:fleet:DesiredCapacity", "dynamodb:table:ReadCapacityUnits", "dynamodb:table:WriteCapacityUnits", "dynamodb:index:ReadCapacityUnits", "dynamodb:index:WriteCapacityUnits", "rds:cluster:ReadReplicaCount", "sagemaker:variant:DesiredInstanceCount", "custom-resource:ResourceType:Property", "comprehend:document-classifier-endpoint:DesiredInferenceUnits", "comprehend:entity-recognizer-endpoint:DesiredInferenceUnits", "lambda:function:ProvisionedConcurrency", "cassandra:table:ReadCapacityUnits", "cassandra:table:WriteCapacityUnits", "kafka:broker-storage:VolumeSize"

ScalableTargetAction => Paws::ApplicationAutoScaling::ScalableTargetAction

The new minimum and maximum capacity. You can set both values or just one. At 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.

Schedule => Str

The schedule for this action. The following formats are supported:

• At expressions - "at(yyyy-mm-ddThh:mm:ss)"
• Rate expressions - ""rate(value unit)""
• Cron expressions - "cron(fields)"

At expressions are useful for one-time schedules. Cron expressions are useful for scheduled actions that run periodically at a specified date and time, and rate expressions are useful for scheduled actions that run at a regular interval.

At and cron expressions use Universal Coordinated Time (UTC) by default.

The cron format consists of six fields separated by white spaces: [Minutes] [Hours] [Day_of_Month] [Month] [Day_of_Week] [Year].

For rate expressions, value is a positive integer and unit is "minute" | "minutes" | "hour" | "hours" | "day" | "days".

For more information and examples, see Example scheduled actions for Application Auto Scaling (https://docs.aws.amazon.com/autoscaling/application/userguide/examples-scheduled-actions.html) in the Application Auto Scaling User Guide.

REQUIRED ScheduledActionName => Str

The name of the scheduled action. This name must be unique among all other scheduled actions on the specified scalable target.

REQUIRED ServiceNamespace => Str

The namespace of the AWS service that provides the resource. For a resource provided by your own application or service, use "custom-resource" instead.

Valid values are: "ecs", "elasticmapreduce", "ec2", "appstream", "dynamodb", "rds", "sagemaker", "custom-resource", "comprehend", "lambda", "cassandra", "kafka"

StartTime => Str

The date and time for this scheduled action to start, in UTC.

Timezone => Str

Specifies the time zone used when setting a scheduled action by using an at or cron expression. If a time zone is not provided, UTC is used by default.

Valid values are the canonical names of the IANA time zones supported by Joda-Time (such as "Etc/GMT+9" or "Pacific/Tahiti"). For more information, see https://www.joda.org/joda-time/timezones.html (https://www.joda.org/joda-time/timezones.html).
