# Sample scaling policy that can be attached to a cluster

adjustment:
  # Adjustment type, valid values include:
  # EXACT_CAPACITY, CHANGE_IN_CAPACITY, CHANGE_IN_PERCENTAGE
  type: CHANGE_IN_CAPACITY

  # A number that will be interpreted based on the type setting
  # Define negative number for scaling in policy and positive
  # number for scaling out policy.
  number: 1
 
  # When type is set CHNAGE_IN_PERCENTAGE, min_step specifies
  # that the cluster size will be changed by at least the number
  # of nodes specified here.
  min_step: 1

  # When scaling operation will break the size limitation of
  # cluster, whether to do best effort scaling, e.g. decrease
  # cluster size to min_size or increase cluster size to max_size
  # Default False means reject scaling request directly.
  best_effort: True
