}

An instance type configuration for each instance type in an instance fleet, which determines the Amazon EC2 instances Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities. When you use an allocation strategy, you can include a maximum of 30 instance type configurations for a fleet. For more information about how to use an allocation strategy, see Configure Instance Fleets. Without an allocation strategy, you may specify a maximum of five instance type configurations for a fleet.

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

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

instance_type: Option<String>

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

weighted_capacity: Option<i32>

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.

bid_price: Option<String>

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%.

bid_price_as_percentage_of_on_demand_price: Option<f64>

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%.

ebs_configuration: Option<EbsConfiguration>

The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType.

configurations: Option<Vec<Configuration>>

A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software that run on the cluster.

custom_ami_id: Option<String>

The custom AMI ID to use for the instance type.

priority: Option<f64>

The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type. Priority starts at 0, which is the highest priority. Amazon EMR considers the highest priority first.

Implementations

impl InstanceTypeConfig

pub fn instance_type(&self) -> Option<&str>

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

pub fn weighted_capacity(&self) -> Option<i32>

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.

pub fn bid_price(&self) -> Option<&str>

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%.

pub fn bid_price_as_percentage_of_on_demand_price(&self) -> Option<f64>

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%.

pub fn ebs_configuration(&self) -> Option<&EbsConfiguration>

The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType.

pub fn configurations(&self) -> &[Configuration]

A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software that run on the cluster.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .configurations.is_none().

pub fn custom_ami_id(&self) -> Option<&str>

The custom AMI ID to use for the instance type.

pub fn priority(&self) -> Option<f64>

The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type. Priority starts at 0, which is the highest priority. Amazon EMR considers the highest priority first.

impl InstanceTypeConfig

pub fn builder() -> InstanceTypeConfigBuilder

Creates a new builder-style object to manufacture InstanceTypeConfig.

Trait Implementations

impl Clone for InstanceTypeConfig

fn clone(&self) -> InstanceTypeConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InstanceTypeConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for InstanceTypeConfig

fn eq(&self, other: &InstanceTypeConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
