Struct ManagedScalingPolicy

#[non_exhaustive]
pub struct ManagedScalingPolicy {
    pub compute_limits: Option<ComputeLimits>,
    pub utilization_performance_index: Option<i32>,
    pub scaling_strategy: Option<ScalingStrategy>,
}

Managed scaling policy for an Amazon EMR cluster. The policy specifies the limits for resources that can be added or terminated from a cluster. The policy only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

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.

compute_limits: Option<ComputeLimits>

The Amazon EC2 unit limits for a managed scaling policy. The managed scaling activity of a cluster is not allowed to go above or below these limits. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

utilization_performance_index: Option<i32>

An integer value that represents an advanced scaling strategy. Setting a higher value optimizes for performance. Setting a lower value optimizes for resource conservation. Setting the value to 50 balances performance and resource conservation. Possible values are 1, 25, 50, 75, and 100.

scaling_strategy: Option<ScalingStrategy>

Determines whether a custom scaling utilization performance index can be set. Possible values include ADVANCED or DEFAULT.

Implementations

impl ManagedScalingPolicy

pub fn compute_limits(&self) -> Option<&ComputeLimits>

The Amazon EC2 unit limits for a managed scaling policy. The managed scaling activity of a cluster is not allowed to go above or below these limits. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

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

An integer value that represents an advanced scaling strategy. Setting a higher value optimizes for performance. Setting a lower value optimizes for resource conservation. Setting the value to 50 balances performance and resource conservation. Possible values are 1, 25, 50, 75, and 100.

pub fn scaling_strategy(&self) -> Option<&ScalingStrategy>

Determines whether a custom scaling utilization performance index can be set. Possible values include ADVANCED or DEFAULT.

impl ManagedScalingPolicy

pub fn builder() -> ManagedScalingPolicyBuilder

Creates a new builder-style object to manufacture ManagedScalingPolicy.

Trait Implementations

impl Clone for ManagedScalingPolicy

fn clone(&self) -> ManagedScalingPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ManagedScalingPolicy

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

Formats the value using the given formatter.

impl PartialEq for ManagedScalingPolicy

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