Distributed metadata management method and system

Abstract

The invention discloses a distributed metadata management method and system, and relates to the technical field of metadata management. By means of the method and the system, two strategies including static load balancing when metadata is distributed and dynamic load balancing in system operation are used; therefore, the utilization rate of metadata service resources is increased; the load balancing of the system is ensured; the expandability of the system is increased; in addition, because a metadata delay movement scheme based on a directory redirection table is used, the problem of a large number of metadata movement due to renaming operation can be solved; and the stability of the system efficiency is ensured.

Description

technical field

[0001] The present invention relates to the technical field of metadata management, in particular to a distributed metadata management method and system. Background technique

[0002] At present, in the face of more and more mass data, due to the limitations of performance and price, the existing storage methods can no longer meet the demand. What the market needs is data with large storage capacity, scalability, security and high availability. Storage system, thus, distributed storage emerges as the times require.

[0003] In order to effectively manage each storage node in the distributed storage system, according to the storage and access characteristics of metadata and data in the file system, the distributed file system generally stores metadata and data separately. The metadata storage system is a bridge connecting users and data storage servers. Therefore, efficient metadata management is very important to achieve high performance and scalability of ...
