Overview

Note:

When making an API call, you may pass ScalingConstraints data as a hash:

{
  min_capacity: 1, # required
  max_capacity: 1, # required
}

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 below these limits.

• AWS API Documentation

Instance Attribute Summary

• #max_capacity ⇒ Integer

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

• #min_capacity ⇒ Integer

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

Instance Attribute Details

#max_capacity ⇒ Integer

The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow. Scale-out activities will not add instances beyond this boundary.

Returns:

• (Integer)

# File 'lib/aws-sdk-emr/types.rb', line 4499

class ScalingConstraints < Struct.new(
  :min_capacity,
  :max_capacity)
  include Aws::Structure
end

#min_capacity ⇒ Integer

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

Returns:

• (Integer)

# File 'lib/aws-sdk-emr/types.rb', line 4499

class ScalingConstraints < Struct.new(
  :min_capacity,
  :max_capacity)
  include Aws::Structure
