Description

Creates or updates an automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric.

Synopsis

Creating a Request

data PutAutoScalingPolicy Source #

See: newPutAutoScalingPolicy smart constructor.

Constructors

PutAutoScalingPolicy'
Fields clusterId :: Text Specifies the ID of a cluster. The instance group to which the automatic scaling policy is applied is within this cluster. instanceGroupId :: Text Specifies the ID of the instance group to which the automatic scaling policy is applied. autoScalingPolicy :: AutoScalingPolicy Specifies the definition of the automatic scaling policy.

Arguments

:: Text	`$sel:clusterId:PutAutoScalingPolicy'`
-> Text	`$sel:instanceGroupId:PutAutoScalingPolicy'`
-> AutoScalingPolicy	`$sel:autoScalingPolicy:PutAutoScalingPolicy'`
-> PutAutoScalingPolicy

Create a value of PutAutoScalingPolicy with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:clusterId:PutAutoScalingPolicy', putAutoScalingPolicy_clusterId - Specifies the ID of a cluster. The instance group to which the automatic scaling policy is applied is within this cluster.

$sel:instanceGroupId:PutAutoScalingPolicy', putAutoScalingPolicy_instanceGroupId - Specifies the ID of the instance group to which the automatic scaling policy is applied.

$sel:autoScalingPolicy:PutAutoScalingPolicy', putAutoScalingPolicy_autoScalingPolicy - Specifies the definition of the automatic scaling policy.
