};Properties
InstanceTypeConfigs
The instance type configurations that define the Amazon EC2 instances in the instance fleet.
public object? InstanceTypeConfigs { get; set; }Property Value
Remarks
LaunchSpecifications
The launch specification for the instance fleet.
public object? LaunchSpecifications { get; set; }Property Value
Remarks
Name
The friendly name of the instance fleet.
public string? Name { get; set; }Property Value
Remarks
ResizeSpecifications
The resize specification for the instance fleet.
public object? ResizeSpecifications { get; set; }Property Value
Remarks
TargetOnDemandCapacity
The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision.
public double? TargetOnDemandCapacity { get; set; }Property Value
Remarks
When the instance fleet launches, Amazon EMR tries to provision On-Demand instances as specified by InstanceTypeConfig . Each instance configuration has a specified WeightedCapacity . When an On-Demand instance is provisioned, the WeightedCapacity 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 a WeightedCapacity 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 <code>TargetSpotCapacity</code> . At least one of <code>TargetSpotCapacity</code> and <code>TargetOnDemandCapacity</code> should be greater than 0. For a master instance fleet, only one of <code>TargetSpotCapacity</code> and <code>TargetOnDemandCapacity</code> can be specified, and its value must be 1.
TargetSpotCapacity
The target capacity of Spot units for the instance fleet, which determines how many Spot instances to provision.
