Overview

The Amazon 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.

Constructor Details

#initialize(maximum_capacity_units:, minimum_capacity_units:, unit_type:, maximum_core_capacity_units: nil, maximum_on_demand_capacity_units: nil) ⇒ ComputeLimitsProperty

Returns a new instance of ComputeLimitsProperty.

Parameters:

  • maximum_capacity_units (Numeric) —

    The upper boundary of Amazon EC2 units.

  • minimum_capacity_units (Numeric) —

    The lower boundary of Amazon EC2 units.

  • unit_type (String) —

    The unit type used for specifying a managed scaling policy.

  • maximum_core_capacity_units (Numeric, nil) (defaults to: nil) —

    The upper boundary of Amazon EC2 units for core node type in a cluster.

  • maximum_on_demand_capacity_units (Numeric, nil) (defaults to: nil) —

    The upper boundary of On-Demand Amazon EC2 units.

Instance Attribute Details

#maximum_capacity_units ⇒ Numeric (readonly)

The upper boundary of Amazon 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.

Returns:

  • (Numeric)

#maximum_core_capacity_units ⇒ Numeric? (readonly)

The upper boundary of Amazon 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.

Returns:

  • (Numeric, nil)

#maximum_on_demand_capacity_units ⇒ Numeric? (readonly)

The upper boundary of On-Demand Amazon 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.

Returns:

  • (Numeric, nil)
