extends software.amazon.jsii.JsiiSerializable

The launch specification for On-Demand Instances in the instance fleet, which determines the allocation strategy.

The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions. On-Demand Instances allocation strategy is available in Amazon EMR releases 5.12.1 and later.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.emr.*;
 OnDemandProvisioningSpecificationProperty onDemandProvisioningSpecificationProperty = OnDemandProvisioningSpecificationProperty.builder()
         .allocationStrategy("allocationStrategy")
         // the properties below are optional
         .capacityReservationOptions(OnDemandCapacityReservationOptionsProperty.builder()
                 .capacityReservationPreference("capacityReservationPreference")
                 .capacityReservationResourceGroupArn("capacityReservationResourceGroupArn")
                 .usageStrategy("usageStrategy")
                 .build())
