Class CfnInstanceGroupConfig.ScalingConstraintsProperty

ScalingConstraints is a subproperty of the AutoScalingPolicy property type.

Inheritance

System.Object

CfnInstanceGroupConfig.ScalingConstraintsProperty

Implements

CfnInstanceGroupConfig.IScalingConstraintsProperty

Namespace: Amazon.CDK.AWS.EMR

Assembly: Amazon.CDK.AWS.EMR.dll

Syntax (csharp)

public class ScalingConstraintsProperty : Object, CfnInstanceGroupConfig.IScalingConstraintsProperty

Syntax (vb)

Public Class ScalingConstraintsProperty
    Inherits Object
    Implements CfnInstanceGroupConfig.IScalingConstraintsProperty

Remarks

ScalingConstraints defines the upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activities triggered by automatic scaling rules will not cause an instance group to grow above or shrink below these limits.

Synopsis

Constructors

ScalingConstraintsProperty()

Properties

MaxCapacity	The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow.
MinCapacity	The lower boundary of EC2 instances in an instance group below which scaling activities are not allowed to shrink.

Constructors

ScalingConstraintsProperty()

public ScalingConstraintsProperty()

Properties

MaxCapacity

The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow.

public double MaxCapacity { get; set; }

Property Value

System.Double

Remarks

Scale-out activities will not add instances beyond this boundary.

MinCapacity

The lower boundary of EC2 instances in an instance group below which scaling activities are not allowed to shrink.

public double MinCapacity { get; set; }

Property Value

System.Double

Remarks

Scale-in activities will not terminate instances below this boundary.
