Class CfnTable.TargetTrackingScalingPolicyConfigurationProperty

Amazon Keyspaces supports the target tracking auto scaling policy for a provisioned table.

Inheritance

System.Object

CfnTable.TargetTrackingScalingPolicyConfigurationProperty

Implements

CfnTable.ITargetTrackingScalingPolicyConfigurationProperty

Namespace: Amazon.CDK.AWS.Cassandra

Assembly: Amazon.CDK.Lib.dll

Syntax (csharp)

public class TargetTrackingScalingPolicyConfigurationProperty : Object, CfnTable.ITargetTrackingScalingPolicyConfigurationProperty

Syntax (vb)

Public Class TargetTrackingScalingPolicyConfigurationProperty
    Inherits Object
    Implements CfnTable.ITargetTrackingScalingPolicyConfigurationProperty

Remarks

This policy scales a table based on the ratio of consumed to provisioned capacity. The auto scaling target is a percentage of the provisioned capacity of the table.

Examples

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
using Amazon.CDK.AWS.Cassandra;

var targetTrackingScalingPolicyConfigurationProperty = new TargetTrackingScalingPolicyConfigurationProperty {
    TargetValue = 123,

    // the properties below are optional
    DisableScaleIn = false,
    ScaleInCooldown = 123,

};

Synopsis

Constructors

TargetTrackingScalingPolicyConfigurationProperty()

Properties

DisableScaleIn	Specifies if `scale-in` is enabled.
ScaleInCooldown	Specifies a `scale-in` cool down period.
ScaleOutCooldown	Specifies a scale out cool down period.
TargetValue	Specifies the target value for the target tracking auto scaling policy.

Constructors

TargetTrackingScalingPolicyConfigurationProperty()

public TargetTrackingScalingPolicyConfigurationProperty()

Properties

DisableScaleIn

Specifies if scale-in is enabled.

public object DisableScaleIn { get; set; }

Property Value

System.Object

Remarks

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.

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cassandra-table-targettrackingscalingpolicyconfiguration.html#cfn-cassandra-table-targettrackingscalingpolicyconfiguration-disablescalein

ScaleInCooldown

Specifies a scale-in cool down period.

public Nullable<double> ScaleInCooldown { get; set; }

Property Value

System.Nullable<System.Double>

Remarks

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

Default: - 0

ScaleOutCooldown

Specifies a scale out cool down period.

public Nullable<double> ScaleOutCooldown { get; set; }

Property Value

System.Nullable<System.Double>

Remarks

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

Default: - 0

TargetValue

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

public double TargetValue { get; set; }

Property Value

System.Double

Remarks

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. An integer between 20 and 90.
