A file deletion method and device

Abstract

The present invention discloses a file deletion method and apparatus. The method comprises: acquiring a to-be-deleted directory from a to-be-deleted directory queue as a current directory according to a preset principle; determining whether the current directory is null, if yes, deleting the directory, and if no, traversing and reading metadata under the current directory, and every time each metadata is read and if a file corresponding to the metadata is determined, deleting the file, and if a directory corresponding to the metadata is determined, using the directory as the current directory and returning to execute the step of determining whether the current directory is null. According to the technical scheme disclosed by the present application, by means of relevant steps of determining the to-be-deleted directory and deleting the corresponding file and by using such a non-recursive cyclic processing mechanism, deletion of the to-be-deleted directory and the corresponding massive files is realized, so that the existing problem in the prior art can be avoided, and while normal operation of the system is ensured, the deletion operation on the massive files is realized.

Description

technical field [0001] The present invention relates to the technical field of distributed file systems, and more specifically, to a file deletion method and device. Background technique [0002] The current distributed file system has been applied to various industries, such as: video surveillance, oil exploration, marine monitoring, radio and television media, etc.; in high-performance scenarios such as oil exploration and marine monitoring, a large number of small files will be generated The data is tens of millions of levels. When these data are used, data cleaning operations are required. To delete such a large number of files, use the delete command that comes with the Linux system to achieve the above delete actions through recursive loop calls. It may burst the function call stack and eventually cause the system to crash. [0003] To sum up, how to provide a technical solution that can realize a massive file deletion operation while ensuring the normal operation of ...
