Method Details

getCapacityReservationPreference

@Stability(Stable)
@Nullable
default String getCapacityReservationPreference()

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.

getCapacityReservationResourceGroupArn

@Stability(Stable)
@Nullable
default String getCapacityReservationResourceGroupArn()

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

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-emr-instancefleetconfig-ondemandcapacityreservationoptions.html#cfn-emr-instancefleetconfig-ondemandcapacityreservationoptions-capacityreservationresourcegrouparn

getUsageStrategy

@Stability(Stable)
@Nullable
default String getUsageStrategy()

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 fulfills the On-Demand capacity according to the chosen On-Demand allocation strategy.
