#[non_exhaustive]
pub struct ComputeLimits {
    pub unit_type: Option<ComputeLimitsUnitType>,
    pub minimum_capacity_units: Option<i32>,

    pub maximum_on_demand_capacity_units: Option<i32>,
    pub maximum_core_capacity_units: Option<i32>,
}

The EC2 unit limits for a managed scaling policy. The managed scaling activity of a cluster can not be above or below these limits. The limit 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.

unit_type: Option<ComputeLimitsUnitType>

The unit type used for specifying a managed scaling policy.

minimum_capacity_units: Option<i32>

The lower boundary of EC2 units. It is measured through vCPU cores or instances for instance groups and measured through units for instance fleets. Managed scaling activities are not allowed beyond this boundary. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

maximum_capacity_units: Option<i32>

The upper boundary of EC2 units. It is measured through vCPU cores or instances for instance groups and measured through units for instance fleets. Managed scaling activities are not allowed beyond this boundary. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

maximum_on_demand_capacity_units: Option<i32>

The upper boundary of On-Demand EC2 units. It is measured through vCPU cores or instances for instance groups and measured through units for instance fleets. The On-Demand units are not allowed to scale beyond this boundary. The parameter is used to split capacity allocation between On-Demand and Spot Instances.

maximum_core_capacity_units: Option<i32>

The upper boundary of EC2 units for core node type in a cluster. It is measured through vCPU cores or instances for instance groups and measured through units for instance fleets. The core units are not allowed to scale beyond this boundary. The parameter is used to split capacity allocation between core and task nodes.

Implementations

impl ComputeLimits

pub fn unit_type(&self) -> Option<&ComputeLimitsUnitType>

The unit type used for specifying a managed scaling policy.

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

The lower boundary of EC2 units. It is measured through vCPU cores or instances for instance groups and measured through units for instance fleets. Managed scaling activities are not allowed beyond this boundary. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

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

The upper boundary of EC2 units. It is measured through vCPU cores or instances for instance groups and measured through units for instance fleets. Managed scaling activities are not allowed beyond this boundary. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

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

The upper boundary of On-Demand EC2 units. It is measured through vCPU cores or instances for instance groups and measured through units for instance fleets.
