Syntax (csharp)
public class CfnClusterPropsMixin.ManagedScalingPolicyProperty : CfnClusterPropsMixin.IManagedScalingPolicyPropertySyntax (vb)
Public Class CfnClusterPropsMixin.ManagedScalingPolicyProperty Implements CfnClusterPropsMixin.IManagedScalingPolicyPropertyRemarks
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.

};Properties
ComputeLimits
The Amazon EC2 unit limits for a managed scaling policy.
public object? ComputeLimits { get; set; }Property Value
Remarks
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.
Type union: either IResolvable or CfnClusterPropsMixin.IComputeLimitsProperty
ScalingStrategy
Determines whether a custom scaling utilization performance index can be set.
public string? ScalingStrategy { get; set; }Property Value
Remarks
Possible values include ADVANCED or DEFAULT .
UtilizationPerformanceIndex
An integer value that represents an advanced scaling strategy.
public double? UtilizationPerformanceIndex { get; set; }Property Value
Remarks
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.
