Overview

The launch specification for Spot Instances in the instance fleet, which determines the defined duration, provisioning timeout behavior, and allocation strategy.

<note markdown=“1”> The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions. Spot Instance allocation strategy is available in Amazon EMR releases 5.12.1 and later.

</note>

<note markdown=“1”> 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.

#allocation_strategy ⇒ String

Specifies one of the following strategies to launch Spot Instance fleets: ‘capacity-optimized`, `price-capacity-optimized`, `lowest-price`, or `diversified`, and `capacity-optimized-prioritized`. For more information on the provisioning strategies, see [Allocation strategies for Spot Instances] in the *Amazon EC2 User Guide for Linux Instances*.

<note markdown=“1”> 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.

  SENSITIVE = []
  include Aws::Structure
end

#block_duration_minutes ⇒ Integer

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

  include Aws::Structure
end

#timeout_action ⇒ String

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

end

#timeout_duration_minutes ⇒ Integer

The Spot provisioning timeout period in minutes. 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.
