NAME

Paws::EMR::OnDemandCapacityReservationOptions

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::OnDemandCapacityReservationOptions object:

  $service_obj->Method(Att1 => { CapacityReservationPreference => $value, ..., UsageStrategy => $value  });

Results returned from an API call

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

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

DESCRIPTION

Describes the strategy for using unused Capacity Reservations for fulfilling On-Demand capacity.

ATTRIBUTES

CapacityReservationPreference => Str

Indicates the instance's Capacity Reservation preferences. Possible preferences include:

"open" - The instance can run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone).
"none" - The instance avoids running in a Capacity Reservation even if one is available. The instance runs as an On-Demand Instance.

CapacityReservationResourceGroupArn => Str

The ARN of the Capacity Reservation resource group in which to run the instance.

UsageStrategy => Str

Indicates whether to use unused Capacity Reservations for fulfilling On-Demand capacity.

If you specify "use-capacity-reservations-first", the fleet uses unused Capacity Reservations to fulfill On-Demand capacity up to the target On-Demand capacity. If multiple instance pools have unused Capacity Reservations, the On-Demand allocation strategy ("lowest-price") is applied. If the number of unused Capacity Reservations is less than the On-Demand target capacity, the remaining On-Demand target capacity is launched according to the On-Demand allocation strategy ("lowest-price").

If you do not specify a value, the fleet fulfils the On-Demand capacity according to the chosen On-Demand allocation strategy.
