NAME

Paws::EMR::SimpleScalingPolicyConfiguration

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::EMR::SimpleScalingPolicyConfiguration object:

  $service_obj->Method(Att1 => { AdjustmentType => $value, ..., ScalingAdjustment => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::EMR::SimpleScalingPolicyConfiguration object:

  $result = $service_obj->Method(...);
  $result->Att1->AdjustmentType

DESCRIPTION

An automatic scaling configuration, which describes how the policy adds or removes instances, the cooldown period, and the number of EC2 instances that will be added each time the CloudWatch metric alarm condition is satisfied.

ATTRIBUTES

AdjustmentType => Str

The way in which EC2 instances are added (if "ScalingAdjustment" is a positive number) or terminated (if "ScalingAdjustment" is a negative number) each time the scaling activity is triggered. "CHANGE_IN_CAPACITY" is the default. "CHANGE_IN_CAPACITY" indicates that the EC2 instance count increments or decrements by "ScalingAdjustment", which should be expressed as an integer. "PERCENT_CHANGE_IN_CAPACITY" indicates the instance count increments or decrements by the percentage specified by "ScalingAdjustment", which should be expressed as an integer. For example, 20 indicates an increase in 20% increments of cluster capacity. "EXACT_CAPACITY" indicates the scaling activity results in an instance group with the number of EC2 instances specified by "ScalingAdjustment", which should be expressed as a positive integer.

CoolDown => Int

The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.

REQUIRED ScalingAdjustment => Int

The amount by which to scale in or scale out, based on the specified "AdjustmentType". A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If "AdjustmentType" is set to "EXACT_CAPACITY", the number should only be a positive integer. If "AdjustmentType" is set to "PERCENT_CHANGE_IN_CAPACITY", the value should express the percentage as an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.
