A system for integrating object changes occurring to an object in a first object
storage system with a second object storage system. The system operates by first
receiving from a first object storage systems a notification of an event relating
to an object in the first object storage system. The system sets up a representation
of the object in a second object storage system in response to the notification
and determines object changes made to the object in the first object storage system
by using the representation in the second object storage system. Finally, the system
determines object changes with the representation in the second storage system.
