摘要： A method for managing multiple generations of an object within a distributed storage system is implemented at a computing device. The computing device receives metadata and content of a first generation of an object from a first client connected to the distributed storage system and stores the first generation's metadata and content within a first storage sub-system. The computing device receives metadata and content of a second generation of the object from a second client connected to the distributed storage system and stores the second generation's metadata and content within a second storage sub-system. The computing device independently replicates the first generation's metadata and content from the first storage sub-system to the second storage sub-system and replicates the second generation's metadata and content from the second storage sub-system to the first storage sub-system such that both storage sub-systems include a replica of the object's first and second generations.

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 system and method for generating replication requests for objects in a distributed storage system is provided. For a respective object in a distributed storage system the following is performed. Replication policies for the object that have not been satisfied are determined. Replication requests are ranked for the object whose replication policies have not been satisfied based on a number of replicas of the object that need to be created in order to satisfy the replication policies for the object. Replication requests are generated for the object based at least in part on the replication policies for the object that have not been satisfied and on a current state of the distributed storage system. At least a subset of the replication requests for the objects in the distributed storage system are distributed to respective instances of the distributed storage system corresponding to the replication requests for execution.

摘要： A system and method for simulating a state of a distributed storage system is provided. A current state of a distributed storage system and replication policies for the objects in the distributed storage system is obtained. Proposed modifications to the current state of the distributed storage system are received. The state of the distributed storage system is simulated over time based on the current state of the distributed storage system, the replication policies for the objects in the distributed storage system, and the proposed modifications to the current state of the distributed storage system. Then reports relating to the time evolution of the current state of the distributed storage system are generated based on the simulation.

摘要： A method for uploading an object into a distributed storage system is implemented at a computing device The computing device splits an object into one or more chunks and uploads the one or more chunks into the distributed storage system. For each uploaded chunk, the computing device receives a write token from the distributed storage system, inserts an entry into an extents table of the object for the chunk in accordance with the received write token and the chunk ID, chunk offset, and chunk size of the chunk, generates a digest of the extents table, the digest representing the one or more chunks that the client expects to be within the distributed storage system, and sends the digest of the extents table to the distributed storage system. The distributed storage system is configured to use the digest to determine whether it has each of the one or more client-expected chunks.
