Instance Attribute Details

#constraints ⇒ Types::ScalingConstraints

The upper and lower Amazon EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

Returns:

• (Types::ScalingConstraints)

# File 'lib/aws-sdk-emr/types.rb', line 241

class AutoScalingPolicy < Struct.new(
  :constraints,
  :rules)
  SENSITIVE = []
  include Aws::Structure
end

#rules ⇒ Array<Types::ScalingRule>

The scale-in and scale-out rules that comprise the automatic scaling policy.

Returns:

• (Array<Types::ScalingRule>)

# File 'lib/aws-sdk-emr/types.rb', line 241
