Struct aws_sdk_emr::model::InstanceGroup

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

This entity represents an instance group, which is a group of instances that have common purpose. For example, CORE instance group is used for HDFS.

Implementations

impl InstanceGroup

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

The identifier of the instance group.

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

The name of the instance group.

pub fn market(&self) -> Option<&MarketType>

The marketplace to provision instances for this group. Valid values are ON_DEMAND or SPOT.

pub fn instance_group_type(&self) -> Option<&InstanceGroupType>

The type of the instance group. Valid values are MASTER, CORE or TASK.

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

If specified, indicates that the instance group uses Spot Instances. This is the maximum price you are willing to pay for Spot Instances. Specify OnDemandPrice to set the amount equal to the On-Demand price, or specify an amount in USD.

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

The EC2 instance type for all instances in the instance group.

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

The target number of instances for the instance group.

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

The number of instances currently running in this instance group.

pub fn status(&self) -> Option<&InstanceGroupStatus>

The current status of the instance group.

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

Amazon EMR releases 4.x or later.

The list of configurations supplied for an Amazon EMR cluster instance group. You can specify a separate configuration for each instance group (master, core, and task).

pub fn configurations_version(&self) -> i64

The version number of the requested configuration specification for this instance group.

pub fn last_successfully_applied_configurations(
    &self
) -> Option<&[Configuration]>

A list of configurations that were successfully applied for an instance group last time.

pub fn last_successfully_applied_configurations_version(&self) -> i64

The version number of a configuration specification that was successfully applied for an instance group last time.

pub fn ebs_block_devices(&self) -> Option<&[EbsBlockDevice]>

The EBS block devices that are mapped to this instance group.

pub fn ebs_optimized(&self) -> Option<bool>

If the instance group is EBS-optimized. An Amazon EBS-optimized instance uses an optimized configuration stack and provides additional, dedicated capacity for Amazon EBS I/O.

pub fn shrink_policy(&self) -> Option<&ShrinkPolicy>

Policy for customizing shrink operations.

pub fn auto_scaling_policy(&self) -> Option<&AutoScalingPolicyDescription>

An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.

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

The custom AMI ID to use for the provisioned instance group.

impl InstanceGroup

pub fn builder() -> Builder

Creates a new builder-style object to manufacture InstanceGroup.

Trait Implementations

impl Clone for InstanceGroup

fn clone(&self) -> InstanceGroup

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceGroup

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

Formats the value using the given formatter.

impl PartialEq<InstanceGroup> for InstanceGroup

fn eq(&self, other: &InstanceGroup) -> 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.
