PARALLEL AND TRANSPARENT TECHNIQUE FOR RETRIEVING ORIGINAL CONTENT THAT IS RESTRUCTURED IN A DISTRIBUTED OBJECT STORAGE SYSTEM

摘要

The present disclosure relates to distributed object storage systems and provides a parallel and transparent technique for retrieving restructured objects using original chunk references. The content retrieval technique disclosed herein may be implemented with parallel operations by multiple storage servers in the system. The retrieval is transparent in that an original reference, referred to as a CHIT, may still be used to retrieve the original content, such that a client requesting the original content need not be aware that the original content has been restructured. Other embodiments, aspects and features are also disclosed.

1. A method for getting content from a distributed object storage system, the method comprising:
receiving, by a storage server of the distributed object storage system, a get request for an original chunk with original-format content of a specified type category, wherein the original chunk is identified by an original chunk identifier token (CHIT); performing a search to find all key-value tuples (KVTs) of the specified category stored at the storage server which have a key that includes the original CHIT, wherein a set of KVTs resulting from the search includes an alternate-index KVT and an alternate chunk KVT, wherein the alternate-index KVT points to the alternate chunk KVT, and wherein the alternate chunk KVT points to alternate-format content; and generating and sending a get response that includes the set of KVTs.
