Problems solved by technology

However, with the development of the file system, more and more data are stored, and the corresponding files and subdirectories in a directory are often tens of thousands or hundreds of thousands. When users operate on the directory, it often happens that the operation of omap is not timely. Response, in extreme cases, the process corresponding to the disk will be disconnected and kicked, seriously affecting the use of users

Abstract

The invention discloses a data acquisition method of a storage object. The method is applied to an object storage server based on a KV (key-value) database, and includes: receiving an operation instruction of the storage object; judging whether a complete region of the storage object exists; and if not, locating all keys of the storage object one by one, and determining a value, which correspondsto each key, to complete data acquisition of the storage object. By applying the technical solution provided by the embodiment of the invention, efficiency of data acquisition of the storage object isgreatly improved. The invention also provides a data acquisition system and data acquisition equipment of the storage object and a computer-readable storage medium, which have corresponding technicaleffects.

Description

technical field [0001] The present invention relates to the technical field of computer storage, and in particular, to a data acquisition method, system, device and storage medium of a storage object. Background technique [0002] In a distributed file system, each directory corresponds to a storage object, and the storage objects are stored in the object storage server in the form of files. The data of these storage objects is usually called metadata. There may be multiple subdirectories or subfiles under each directory of a distributed file system. For example, there are three directories in a distributed file system, corresponding to three storage objects: file A, file B, and file C. There may be multiple subdirectories or subfiles in file A, such as file A1, file A2, and file A3, and each subfile has its corresponding creation time, size, permissions, and other information. [0003] The data of the storage object is usually stored in the form of KV. KV refers to the key...
