摘要：
A system and method for generating replication requests for objects in a distributed storage system is provided. Replication requests for objects in a distributed storage system are generated based at least in part on replication policies for the objects and a current state of the distributed storage system, wherein a respective replication request for a respective object instructs a respective instance of the distributed storage system to replicate the respective object so as to at least partially satisfy a replication policy for the respective object, wherein a respective replication policy includes criteria specifying at least storage device types on which replicas of object are to be stored. At least a subset of the replication requests is then distributed to the respective instances of the distributed storage system for execution.
