A method and system for quickly merging files

Abstract

The invention discloses a method and a system for fast merging of files, so that the merging of files consumes a small part of disk reading and writing capabilities, and can be merged quickly. Its technical scheme is: create a new extension structure in the extension header of the index node of the first file; assign the information of the extension header of the index node of the second file to the new extension structure of the first file, so that the second file The content of the first file is concatenated to the first file; the second file is deleted through the file system command to complete the merger of the first file and the second file.

Description

technical field [0001] The invention relates to data storage technology in the computer field, in particular to a method and a system for quickly merging different files. Background technique [0002] With the development of cloud computing technology, more application scenarios have emerged: segment a certain file, then perform concurrent processing, and then splice the files after the processing is completed. [0003] The purpose of file segmentation is to speed up the processing process after concurrency to achieve higher efficiency. However, since the subsequent splicing needs to be read from the disk and written back to form a file, this processing logic can only be performed serially, resulting in overall The efficiency improvement is not obvious enough. [0004] In detail, concurrent processing is performed on slices, and multiple slice files are formed after the processing is completed. The current general practice is to open the first slice file and prepare to add...

Problems solved by technology

The disadvantage of this is: on the one hand, it greatly consumes the read and write performance of the disk, and on the other hand, it takes time to read and write, resulting in a long time-consuming merge process, which affects the performance of the overall work
