Abstract

The invention discloses a dynamic duplicate consistency maintenance system and method, and a cloud storage platform. The system comprises a request receiving module used for receiving a duplicate updating request sent by a client to a meta data server end through a high consistency principle; a file obtaining module used for obtaining a corresponding updating file queue in the meta data server end after the meta data server end responds to the duplicate updating request received by the request receiving module; and a low consistency maintenance module used for executing low consistency maintenance processing of a duplicate between the meta data server end and a storage server end by use of the updating file queue. According to the invention, maintenance processing performed on the duplicate on a cloud storage platform simultaneously on the basis of the high consistency principle and a low consistency principle, the advantage of quite high duplicate access efficiency of the high consistency principle is integrated, the advantage of quite small system resource consumption of the low consistency principle is also introduced, consumption of too much system resources is avoided, and a certain duplicate access rate is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a dynamic copy consistency maintenance system, method and cloud storage platform. Background technique [0002] At present, a copy consistency maintenance method is usually adopted in cloud storage systems to achieve synchronization between copies, for example, the consistency maintenance process is performed on the copies based on the principle of strong consistency or weak consistency. However, in the current cloud storage system, the consistency maintenance of the copy is either based on the principle of strong consistency, or the consistency maintenance of the copy is performed on the basis of the principle of weak consistency. Among them, although the copy maintenance process based on strong consistency It can ensure that the copy has the latest data, which is beneficial to improve the access efficiency of the copy, but it consumes a lot of system resources; while the ...
