Problems solved by technology
[0003] In the existing technology, for multiple file creation requests in the same directory, it is usually necessary to traverse to check whether the root directory capacity and storage node capacity meet the file creation requirements, and only one file creation request can be processed at a time during the traversal process. The purpose of processing requests concurrently on the same directory cannot be achieved, making file creation inefficient and time-consuming

The invention provides a file creation method, device and system and a storage medium, relates to the field of video file systems. The method is applied to a data storage node in a video file system.The method comprises: obtaining a plurality of file creation requests; the plurality of file creation requests comprising a plurality of file identifiers and root directory identifiers to which the plurality of file identifiers belong; determining a target capacity space identifier corresponding to each file identifier according to the root directory identifier; wherein the target capacity space corresponding to the target capacity space identifier belongs to a plurality of capacity spaces corresponding to the root directory identifier; and creating a file corresponding to each file identifierinto a target capacity space corresponding to the target capacity space identifier. According to the method and the device, the traversal query time is saved, the multiple file creation requests on the same root directory can be concurrently processed, and the file creation efficiency is improved.
Description
technical field [0001] The present application relates to the field of video file systems, in particular, to a file creation method, device, system and storage medium. Background technique [0002] Current file storage solutions generally adopt a distributed file system architecture, which has a large storage capacity and is scalable and concurrent. Among them, the video monitoring file system is a file system specially for monitoring video files. Before storing video information, it is usually necessary to create files for storing video information. Therefore, when the video file system receives a large number of file creation requests, especially When there are a large number of file creation requests in the same directory, how to ensure the efficiency of file creation and increase the number of concurrent file creation is the key issue for improving file system performance. [0003] In the existing technology, for multiple file creation requests in the same directory, it...
