public static enum EmrCreateCluster.OnDemandAllocationStrategy
extends Enum<EmrCreateCluster.OnDemandAllocationStrategy>
On-Demand Allocation Strategies.
Specifies the strategy to use in launching On-Demand instance fleets. Currently, the only option is "lowest-price" (the default), which launches the lowest price first.
Example:
EmrCreateCluster.Builder.create(this, "OnDemandSpecification") .instances(InstancesConfigProperty.builder() .instanceFleets(List.of(InstanceFleetConfigProperty.builder() .instanceFleetType(EmrCreateCluster.getInstanceRoleType().MASTER) .launchSpecifications(InstanceFleetProvisioningSpecificationsProperty.builder() .onDemandSpecification(OnDemandProvisioningSpecificationProperty.builder() .allocationStrategy(EmrCreateCluster.getOnDemandAllocationStrategy().LOWEST_PRICE) .build()) .build()) .build())) .build()) .name("OnDemandCluster") .integrationPattern(IntegrationPattern.RUN_JOB) .build(); EmrCreateCluster.Builder.create(this, "SpotSpecification") .instances(InstancesConfigProperty.builder() .instanceFleets(List.of(InstanceFleetConfigProperty.builder() .instanceFleetType(EmrCreateCluster.getInstanceRoleType().MASTER) .launchSpecifications(InstanceFleetProvisioningSpecificationsProperty.builder() .spotSpecification(SpotProvisioningSpecificationProperty.builder() .allocationStrategy(EmrCreateCluster.getSpotAllocationStrategy().CAPACITY_OPTIMIZED) .timeoutAction(EmrCreateCluster.getSpotTimeoutAction().TERMINATE_CLUSTER) .timeout(Duration.minutes(5)) .build()) .build()) .build())) .build()) .name("SpotCluster") .integrationPattern(IntegrationPattern.RUN_JOB) .build();
