Abstract
A deferred mechanism of rolling attribute changes to objects at transaction commit time is described. To support rolling updates, attributes are categorized into three types—increment, decrement or replace. Since transactions are committed in order, the update process uses a notification list of dependent transactions to propagate attribute changes as a function of attribute category or type. Shadow based file-systems (with or without object versioning) realize efficiency gains by employing the deferred mechanism.
