NAME

Paws::EMR::SpotProvisioningSpecification

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::EMR::SpotProvisioningSpecification object:

  $service_obj->Method(Att1 => { AllocationStrategy => $value, ..., TimeoutDurationMinutes => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::EMR::SpotProvisioningSpecification object:

  $result = $service_obj->Method(...);
  $result->Att1->AllocationStrategy

DESCRIPTION

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

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions. Spot Instance allocation strategy is available in Amazon EMR version 5.12.1 and later.

ATTRIBUTES

AllocationStrategy => Str

Specifies the strategy to use in launching Spot Instance fleets. Currently, the only option is capacity-optimized (the default), which launches instances from Spot Instance pools with optimal capacity for the number of instances that are launching.

BlockDurationMinutes => Int

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.

REQUIRED TimeoutAction => Str

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.

REQUIRED TimeoutDurationMinutes => Int

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.
