Struct rusoto_emr::OnDemandCapacityReservationOptions

pub struct OnDemandCapacityReservationOptions {
    pub capacity_reservation_preference: Option<String>,
    pub capacity_reservation_resource_group_arn: Option<String>,
    pub usage_strategy: Option<String>,
}

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

Fields

capacity_reservation_preference: Option<String>

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.

capacity_reservation_resource_group_arn: Option<String>

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

usage_strategy: Option<String>

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.
