Abstract

The invention discloses a file uploading method and device, a file accessing method and device, and a device. The file uploading method comprises the steps of obtaining target file data of a target file; packaging the target file data into sub-files; writing the at least one sub-file into the data file of the target file in a distributed file system; and writing update meta-information of the data file after the at least one sub-file, wherein the update meta-information of the data file comprises the attribute information of all sub-files of the written target file. According to the methods and the devices, when the file is uploaded, only a piece of update meta-information comprising the attribute information of all sub-files needs to be maintained, so the meta-information of each sub-file is prevented from being maintained respectively, and the storage resource and maintaining resources of the system are saved. The sub-files do not need to be synthesized into the target file, so a client device can read the file data of the target file in the distributed file system at any time.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a file upload method, access method, device and equipment. Background technique [0002] In the cloud storage network architecture, it usually includes an upload device for uploading real-time files, and a distributed file system for saving files. The distributed file system includes multiple storage servers. files to access. When the upload device uploads a target file to the distributed file system, it is necessary to add meta (meta) information at the end of the target file. When the user terminal accesses the target file from the distributed file system, by reading The meta information parses the target file. [0003] In the prior art, in order to satisfy the purpose that the user terminal can access the file data of the target file as soon as possible, the uploading device can divide the file data into several sub-files for uploading, and corresponding me...
