Struct aws_sdk_emr::types::InstanceTypeConfig

#[non_exhaustive]
pub struct InstanceTypeConfig { /* private fields */ }

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.

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) -> Option<&[Configuration]>

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

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

The custom AMI ID to use for the instance type.

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<InstanceTypeConfig> for InstanceTypeConfig

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

This method tests for self and other values to be equal, and is used by ==.

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

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