InstanceTypeConfig class

An instance type configuration for each instance type in an instance fleet, which determines the EC2 instances Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities. There can be a maximum of five instance type configurations in a fleet.

Constructors

InstanceTypeConfig({required String instanceType, String? bidPrice, double? bidPriceAsPercentageOfOnDemandPrice, List<Configuration>? configurations, EbsConfiguration? ebsConfiguration, int? weightedCapacity})

Properties

bidPrice → String?
The bid price for each EC2 Spot Instance type as defined by InstanceType. Expressed in USD. If neither BidPrice nor BidPriceAsPercentageOfOnDemandPrice is provided, BidPriceAsPercentageOfOnDemandPrice defaults to 100%.
final
bidPriceAsPercentageOfOnDemandPrice → double?
The bid price, as a percentage of On-Demand price, for each EC2 Spot Instance as defined by InstanceType. Expressed as a number (for example, 20 specifies 20%). If neither BidPrice nor BidPriceAsPercentageOfOnDemandPrice is provided, BidPriceAsPercentageOfOnDemandPrice defaults to 100%.
final
configurations → List<Configuration>?
A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software that run on the cluster.
final
ebsConfiguration → EbsConfiguration?
The configuration of Amazon Elastic Block Storage (Amazon EBS) attached to each instance as defined by InstanceType.
final
hashCode → int
The hash code for this object.
no setterinherited
instanceType → String
An EC2 instance type, such as m3.xlarge.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
weightedCapacity → int?
The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig. This value is 1 for a master instance fleet, and must be 1 or greater for core and task instance fleets. Defaults to 1 if not specified.
