  -Once a quota is created and usage statistics are up-to-date, the project accepts the
  -creation of new content. When you create resources, your quota usage is incremented
  -immediately upon the request to create or modify the resource. When you delete
  -a resource, your quota use is decremented during the next full recalculation of
  -quota statistics for the project. As a result, it may take a moment for your quota
  -usage statistics to be reduced to their current observed system value when you
  -delete resources.

  == Overview
  
  A *ResourceQuota* object enumerates hard resource usage limits per project. It
  limits the total number of a particular type of object that may be created in
  a project, and the total amount of compute resources that may be consumed by
  resources in that project.
  
  == Usage Limits
  
  The following describes the set of limits that may be enforced by a
  *ResourceQuota*.
