Problems solved by technology

[0006] Aiming at the problem in the related art that the update operation efficiency of metadata in the distributed data storage system is not high, which leads to a decrease in the availability of system data, the present invention proposes a management method for metadata, which can optimize the storage structure of metadata, thereby improving the availability of metadata. The efficiency of updating metadata nodes provides a new idea for the convenient and effective management of metadata, thereby improving the resource utilization of distributed data storage systems

Abstract

The invention discloses a method and a device for managing metadata. The method comprises the following steps: allocating the metadata into a plurality of assemblages; saving the plurality of assemblages of the metadata in a mode of full copy at each node of a plurality of nodes; and according to a request of a user, accessing partial or total assemblages which are saved in the nodes. According to the invention, the metadata are allocated into the plurality of assemblages and are saved in the nodes and then service is provided for the user, so that the resource of the metadata can be integrated and the storage structure of the metadata is optimized. Therefore, the efficiency of updating the nodes of the metadata is increased. In addition, as the mode of full copy is adopted, the data loss is reduced and the resource utilization rate of distributed data storage systems is increased.

Description

technical field [0001] The present invention relates to the computer field, and in particular, relates to a method and device for managing metadata. Background technique [0002] Metadata storage is an important link in a distributed storage system. In recent years, with the sharp increase in data volume, distributed storage technology has become a commonly used technology, and various distributed file systems and distributed database software emerge in endlessly. These Technologies use different mechanisms to store metadata. In practical applications, metadata is frequently read. In order to ensure the efficiency of distributed systems, metadata can be organized into specific data structures and stored in memory. Metadata nodes are key modules that affect the availability of the entire distributed storage system. The read and write operations of the client to the distributed system must go through the metadata node. Metadata nodes generally need to have a larger memory, ...
