An Improved implementation of Object-Replicator

The goal of this blueprint is to improve the efficiency of object-replicator. In Swift, the object-replicator plays an important role in keeping data consistency and data durability. But, for the production environment of billions of objects, the performance of object-replicator is not so good because of the time-consuming phase of synchronizing data. Moreover, the time for synchronizing data will infect the data durability and data consistency during failure. So, to optimize the mechanism of object-replicator is necessary.

This blueprint improves the performance of object-replicator, please read the full specification to got how it works:http://wiki.openstack.org/Swift-Improved-Object-Replicator
