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.

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.

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.

A method may be performed by a device of a group of devices in a distributed data replication system. The method may include storing objects in a data store, at least one or more of the objects being replicated with the distributed data replication system, and conducting a scan of the objects in the data store. The method may further include identifying one of the objects as not having a reference pointing to the object, storing a delete negotiation message as metadata associated with the one of the objects, and replicating the metadata with the delete negotiation message to one or more other devices of the group of devices.

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.

A system and method for determining an age of an object is provided. A first index for a timestamp entry in a sequence of timestamps corresponding to a time at which an object was created is identified. At least one subsequence of timestamps from the sequence of timestamps having indexes for entries in the sequence of timestamps that are between the first index in the sequence of timestamps and a last index for a last timestamp entry in the sequence of timestamps is identified, wherein the at least one subsequence of timestamps conforms to a function of a time interval between storage of consecutive current timestamps reported by clock of the computer system. Timestamps from the sequence of timestamps that are not included in the at least one subsequence of timestamps are removed. An age of the object is determined based on the at least one subsequence of timestamps.
