Problems solved by technology

[0005] However, for the establishment of the client of the distributed storage system, and requests for reading and writing files, usually only one mds provides services. When a large number of files are read and written at the same time, the pressure on the mds will be increased, thereby affecting the overall performance of the distributed storage system. and stability

Abstract

The embodiment of the invention discloses a directory load balancing method, device and apparatus of a distributed storage system and a computer readable storage medium. The method includes setting directory and depth of directory load balancing rule of metadata server cluster in a client end of a distributed storage system in advance, wherein the path and depth of directory load balancing rule constitute directory load balancing rule data structure, and a plurality of directory load balancing rule data structures constitute a directory data structure diagram. When the target directory balancing rule can be matched by traversing the directory data structure diagram according to the path of the new directory, a request for creating a new directory with an identification parameter is sent tothe metadata server cluster, so that the metadata server cluster polls and selects a target metadata server to provide service for the directory according to the identification parameter. The technical proposal provided by the application scatters the pressure of the mds server cluster, is favorable for improving the data processing efficiency of the distributed storage system, and improves the performance and stability of the distributed storage system.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data reading and writing in a distributed storage system, and in particular to a directory load balancing method, device, device, and computer-readable storage medium for a distributed storage system. Background technique [0002] With the rapid development of cloud technology and big data, the explosive growth of data has prompted the corresponding development of storage technology to meet the actual needs of data storage. The traditional network storage system uses a centralized storage server to store all data. The storage server becomes the bottleneck of system performance, and there are also hidden dangers in reliability and security. It cannot meet the needs of large-scale storage applications. Distributed storage systems emerge as the times require. [0003] The distributed storage system disperses and stores data on multiple independent devices. It adopts a scalable system st...
