extends software.amazon.jsii.JsiiSerializable

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

InstanceTypeConfig is a sub-property of InstanceFleetConfig . InstanceTypeConfig determines the EC2 instances that Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities.

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.*;
 ConfigurationProperty configurationProperty_;
 InstanceTypeConfigProperty instanceTypeConfigProperty = InstanceTypeConfigProperty.builder()
         .instanceType("instanceType")
         // the properties below are optional
         .bidPrice("bidPrice")
         .bidPriceAsPercentageOfOnDemandPrice(123)

getInstanceType

@Stability(Stable)
@NotNull
String getInstanceType()

An Amazon EC2 instance type, such as m3.xlarge .

getBidPrice

@Stability(Stable)
@Nullable
default String getBidPrice()

The bid price for each Amazon EC2 Spot Instance type as defined by InstanceType .

Expressed in USD. If neither BidPrice nor BidPriceAsPercentageOfOnDemandPrice is provided, BidPriceAsPercentageOfOnDemandPrice defaults to 100%.

getBidPriceAsPercentageOfOnDemandPrice

@Stability(Stable)
@Nullable
default Number getBidPriceAsPercentageOfOnDemandPrice()

The bid price, as a percentage of On-Demand price, for each Amazon 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%.

getConfigurations

@Stability(Stable)
@Nullable
default Object getConfigurations()

default String getCustomAmiId()

The custom AMI ID to use for the instance type.

getEbsConfiguration

@Stability(Stable)
@Nullable
default Object getEbsConfiguration()

getWeightedCapacity

@Stability(Stable)
@Nullable
default Number getWeightedCapacity()

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.
