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.

摘要： A method is performed by two or more devices of a group of devices in a distributed data replication system. The method includes receiving, at the two or more devices, a group of chunks having a same unique temporary identifier, where the group of chunks comprises an object to be uploaded; creating an entry for the object in a replicated index, where the entry is keyed by the unique temporary identifier, and where the replicated index is replicated at each of the two or more devices; and determining, by an initiating device of the two or more devices, that a union of the group of chunks contains all data of the object. The method also includes calculating a content-based identifier to the object; creating another entry for the object in the replicated index, where the other entry is keyed by the content-based identifier; and updating the replicated index to point from the unique temporary identifier to the content-based identifier.

摘要： Systems and methods for controlling access to relationship information in a social network are described. One described method comprises receiving a request from an observer for relationship information indicating at least a first relationship between a target in a social network and a second entity in the social network, identifying at least a first privacy rule for the first relationship, and outputting at least part of the relationship information to the observer if the first privacy rule is satisfied.

摘要： A system and method generating and distributing replica removal requests for objects in a distributed storage system is provided. Replica removal requests for objects in a distributed storage system are generated based at least in part on replication policies for the objects. A respective replica removal request instructs a respective instance of the distributed storage system to remove a respective replica of the respective object so as to at least partially satisfy replication policies for the respective object. Then the replica removal requests for the objects in the distributed storage system are distributed to respective instances of the distributed storage system corresponding to the replica removal requests for execution.

摘要： A server computer at a first storage sub-system of a distributed storage system receives from a client a first client request for an object. If the object is not present in the first storage sub-system, the server computer identifies a second storage sub-system of the distributed storage system as having a replica of the requested object, the requested object including content and metadata. The server computer submits an object replication request for the requested object to the second storage sub-system and independently receives the content and metadata of the requested object from the second storage sub-system. The server computer generates a new replica of the object at the first storage sub-system using the received metadata and content and returns the metadata of the new replica of the object to the client.

摘要： A method is performed by a device of a group of devices in a distributed data replication system. The method includes storing an index of objects in the distributed data replication system, the index being replicated while the objects are stored locally by the plurality of devices in the distributed data replication system. The method also includes conducting a scan of at least a portion of the index and identifying a redundant replica(s) of the at least one of the objects based on the scan of the index. The method further includes de-duplicating the redundant replica(s), and updating the index to reflect the status of the redundant replica.
