Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0055] In the prior art, the specific realization of the file copy operation is: simultaneously open the copied source file and the destination file, read the data in the source file, and write into the destination file. As a result, the same data is saved in two copies in the system, resulting in waste of space, and the copying process needs to read and write data, and the operation process is slow, especially when storing large files.

[0056] The embodiment of the present applicati...

Abstract

The invention discloses a data processing method and system, electronic equipment and a computer readable storage medium, and the method comprises the steps: sending current copy operation informationto a metadata server after a copy request of a file is received, so that the metadata server records the copy operation information; after obtaining a modification request of the file, obtaining corresponding copy operation information in the metadata server by utilizing the modification request; and issuing the modification request and the copy operation information to a server, so that the server determines a target modification object according to the modification request and the copy operation information, copies the target modification object, and executes a modification operation on thecopied target modification object. When the file is copied, only the information of the current copying operation is recorded instead of actually executing the copying operation, and when the data isreally modified, the corresponding data is subjected to the copying operation and is modified, so that the problem of storage space waste in the prior art is solved, and the data processing efficiency is further improved.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a data processing method and system, an electronic device and a computer-readable storage medium. Background technique [0002] The common distributed file system architecture is composed of DOS (Distributed Object Storage System), MDS (Metadata Service) and CA (Client Agent) at the bottom. Among them, DOS is composed of multiple server devices, responsible for data Reliably distributed to these devices, it provides an object-based data access interface; MDS provides metadata services, in which metadata can be stored in DOS or independently; CA interacts with MDS and DOS at the same time, and implements the file access interface externally; The data of the file is divided into data blocks of a certain size, and each block is stored in DOS as an object. [0003] Users generally access the file system through POSIX (portable operating system interface of unix,...
