  +== Configuring the Quota Synchronization Period
  +
  +When a set of resources are deleted, the synchronization timeframe of resources
  +is determined by the `*resource-quota-sync-period*` setting in the
  +*_/etc/openshift/master/master-config.yaml_* file. Before your quota usage is
  +restored, you may encounter problems when attempting to reuse the resources.
  +Change the `*resource-quota-sync-period*` setting to have the set of resources
  +regenerate at the desired amount of time (in seconds) and for the resources to
  +be available again:
  +
  +====
  +----
  +kubernetesMasterConfig:
  +  apiLevels:
  +  - v1beta3
  +  - v1
  +  apiServerArguments: null
  +  controllerArguments:
  +    resource-quota-sync-period:
  +      - "10s"
  +----
  +====
  +
  +Adjusting the regeneration time can be helpful for creating resources and
  +determining resource usage when automation is used.
  +
  +[NOTE]
  +====
  +The `*resource-quota-sync-period*` setting is designed to balance system
  +performance. Reducing the sync period can result in a heavy load on
  +the master.

  == Overview
  
  A *ResourceQuota* object enumerates hard resource usage limits per project.  It
  can limit 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*.

  == Quota Enforcement
  
  After a project quota is first created, the project restricts the ability
  to create any new resources that may violate a quota constraint until it has
  calculated updated usage statistics.
  
  Once a quota is created and usage statistics are up-to-date, the project accepts
  the creation of new content. When you create or modify 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. When you delete
  resources, a link:#configuring_quota_sync_period[configurable amount of time]
  determines how long it takes to reduce quota usage statistics to their current
  observed system value.
  
  If project modifications exceed a quota usage limit, the server denies the
  action, and an appropriate error message is returned to the end-user explaining
  the quota constraint violated, and what their currently observed usage stats are
  in the system.
