Public Class SpotProvisioningSpecificationProperty
    Inherits Object
    Implements CfnCluster.ISpotProvisioningSpecificationProperty

Remarks

SpotProvisioningSpecification determines the launch specification for Spot instances in the instance fleet, which includes the defined duration and provisioning timeout behavior.

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

Synopsis

Constructors

SpotProvisioningSpecificationProperty()

Properties

AllocationStrategy	Specifies one of the following strategies to launch Spot Instance fleets: `price-capacity-optimized` , `capacity-optimized` , `lowest-price` , or `diversified` .
BlockDurationMinutes	The defined duration for Spot Instances (also known as Spot blocks) in minutes.
TimeoutAction	The action to take when `TargetSpotCapacity` has not been fulfilled when the `TimeoutDurationMinutes` has expired;
TimeoutDurationMinutes	The Spot provisioning timeout period in minutes.

Constructors

public SpotProvisioningSpecificationProperty()

Properties

AllocationStrategy

Specifies one of the following strategies to launch Spot Instance fleets: price-capacity-optimized , capacity-optimized , lowest-price , or diversified .

public string AllocationStrategy { get; set; }

Property Value

System.String

Remarks

For more information on the provisioning strategies, see Allocation strategies for Spot Instances in the Amazon EC2 User Guide for Linux Instances .

When you launch a Spot Instance fleet with the old console, it automatically launches with the capacity-optimized strategy. You can't change the allocation strategy from the old console.

BlockDurationMinutes

The defined duration for Spot Instances (also known as Spot blocks) in minutes.

public Nullable<double> BlockDurationMinutes { get; set; }

Property Value

System.Nullable<System.Double>

Remarks

When specified, the Spot Instance does not terminate before the defined duration expires, and defined duration pricing for Spot Instances applies. Valid values are 60, 120, 180, 240, 300, or 360. The duration period starts as soon as a Spot Instance receives its instance ID. At the end of the duration, Amazon EC2 marks the Spot Instance for termination and provides a Spot Instance termination notice, which gives the instance a two-minute warning before it terminates.

Spot Instances with a defined duration (also known as Spot blocks) are no longer available to new customers from July 1, 2021. For customers who have previously used the feature, we will continue to support Spot Instances with a defined duration until December 31, 2022.

TimeoutAction

The action to take when TargetSpotCapacity has not been fulfilled when the TimeoutDurationMinutes has expired;

public string TimeoutAction { get; set; }

Property Value

System.String

Remarks

that is, when all Spot Instances could not be provisioned within the Spot provisioning timeout. Valid values are TERMINATE_CLUSTER and SWITCH_TO_ON_DEMAND . SWITCH_TO_ON_DEMAND specifies that if no Spot Instances are available, On-Demand Instances should be provisioned to fulfill any remaining Spot capacity.

TimeoutDurationMinutes

The Spot provisioning timeout period in minutes.

public double TimeoutDurationMinutes { get; set; }

Property Value

System.Double

Remarks

If Spot Instances are not provisioned within this time period, the TimeOutAction is taken. Minimum value is 5 and maximum value is 1440. The timeout applies only during initial provisioning, when the cluster is first created.
