Struct TargetTrackingScalingPolicyConfiguration

#[non_exhaustive]
pub struct TargetTrackingScalingPolicyConfiguration {
    pub disable_scale_in: bool,
    pub scale_in_cooldown: i32,
    pub scale_out_cooldown: i32,
    pub target_value: f64,
}

The auto scaling policy that scales a table based on the ratio of consumed to provisioned capacity.

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.

disable_scale_in: bool

Specifies if scale-in is enabled.

When auto scaling automatically decreases capacity for a table, the table scales in. When scaling policies are set, they can't scale in the table lower than its minimum capacity.

scale_in_cooldown: i32

Specifies a scale-in cool down period.

A cooldown period in seconds between scaling activities that lets the table stabilize before another scaling activity starts.

scale_out_cooldown: i32

Specifies a scale out cool down period.

A cooldown period in seconds between scaling activities that lets the table stabilize before another scaling activity starts.

target_value: f64

Specifies the target value for the target tracking auto scaling policy.

Amazon Keyspaces auto scaling scales up capacity automatically when traffic exceeds this target utilization rate, and then back down when it falls below the target. This ensures that the ratio of consumed capacity to provisioned capacity stays at or near this value. You define targetValue as a percentage. A double between 20 and 90.

Implementations

impl TargetTrackingScalingPolicyConfiguration

pub fn disable_scale_in(&self) -> bool

Specifies if scale-in is enabled.

When auto scaling automatically decreases capacity for a table, the table scales in. When scaling policies are set, they can't scale in the table lower than its minimum capacity.

pub fn scale_in_cooldown(&self) -> i32

Specifies a scale-in cool down period.

A cooldown period in seconds between scaling activities that lets the table stabilize before another scaling activity starts.

pub fn scale_out_cooldown(&self) -> i32

Specifies a scale out cool down period.

A cooldown period in seconds between scaling activities that lets the table stabilize before another scaling activity starts.

pub fn target_value(&self) -> f64

Specifies the target value for the target tracking auto scaling policy.

Amazon Keyspaces auto scaling scales up capacity automatically when traffic exceeds this target utilization rate, and then back down when it falls below the target. This ensures that the ratio of consumed capacity to provisioned capacity stays at or near this value. You define targetValue as a percentage. A double between 20 and 90.

impl TargetTrackingScalingPolicyConfiguration

pub fn builder() -> TargetTrackingScalingPolicyConfigurationBuilder

Creates a new builder-style object to manufacture TargetTrackingScalingPolicyConfiguration.

Trait Implementations

impl Clone for TargetTrackingScalingPolicyConfiguration

fn clone(&self) -> TargetTrackingScalingPolicyConfiguration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TargetTrackingScalingPolicyConfiguration

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

Formats the value using the given formatter.

impl PartialEq for TargetTrackingScalingPolicyConfiguration

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