Defined in:

emr/cfn_cluster.rb

Overview

ScalingConstraints is a subproperty of the AutoScalingPolicy property type.

ScalingConstraints defines 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 shrink below these limits.

Instance Attribute Summary

• #max_capacity ⇒ Numeric readonly

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

• #min_capacity ⇒ Numeric readonly

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

Instance Method Summary

• #initialize(max_capacity:, min_capacity:) ⇒ ScalingConstraintsProperty constructor

Constructor Details

#initialize(max_capacity:, min_capacity:) ⇒ ScalingConstraintsProperty

Returns a new instance of ScalingConstraintsProperty.

Parameters:

Instance Attribute Details

#max_capacity ⇒ Numeric (readonly)

The upper boundary of Amazon 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:

• (Numeric)

def max_capacity
  @max_capacity
end

#min_capacity ⇒ Numeric (readonly)

The lower boundary of Amazon 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:

• (Numeric)
