targetOnDemandCapacity
@Stability(Stable) public CfnInstanceFleetConfig.Builder targetOnDemandCapacity(Number targetOnDemandCapacity) The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision.When the instance fleet launches, Amazon EMR tries to provision On-Demand instances as specified by
InstanceTypeConfig
. Each instance configuration has a specifiedWeightedCapacity
. When an On-Demand instance is provisioned, theWeightedCapacity
units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EMR can only provision an instance with aWeightedCapacity
of 5 units, the instance is provisioned, and the target capacity is exceeded by 3 units.If not specified or set to 0, only Spot instances are provisioned for the instance fleet using
TargetSpotCapacity
. At least one ofTargetSpotCapacity
andTargetOnDemandCapacity
should be greater than 0. For a master instance fleet, only one ofTargetSpotCapacity
andTargetOnDemandCapacity
can be specified, and its value must be 1.- Parameters:
targetOnDemandCapacity
- The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision. This parameter is required.- Returns:
this
-
targetSpotCapacity
@Stability(Stable) public CfnInstanceFleetConfig.Builder targetSpotCapacity(Number targetSpotCapacity) The target capacity of Spot units for the instance fleet, which determines how many Spot instances to provision.When the instance fleet launches, Amazon EMR tries to provision Spot instances as specified by
InstanceTypeConfig
. Each instance configuration has a specifiedWeightedCapacity
. When a Spot instance is provisioned, theWeightedCapacity
units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EMR can only provision an instance with aWeightedCapacity
of 5 units, the instance is provisioned, and the target capacity is exceeded by 3 units.If not specified or set to 0, only On-Demand instances are provisioned for the instance fleet. At least one of
TargetSpotCapacity
andTargetOnDemandCapacity
should be greater than 0. For a master instance fleet, only one ofTargetSpotCapacity
andTargetOnDemandCapacity
can be specified, and its value must be 1.- Parameters:
targetSpotCapacity
- The target capacity of Spot units for the instance fleet, which determines how many Spot instances to provision. This parameter is required.- Returns:
this
