Index-code-based virtual file system, establishment method and access method

Abstract

The invention discloses an index-code-based virtual file system, an establishment method and an access method, decreases read and write operations generated during file merge, reduces system IO load, and ensures that a file merge operation is completed without reading or writing content. The technical scheme is as follows: a system comprises an interface module, for receiving a merge request from a user and generating an index file, wherein the merge request contains a plurality of original files and target mirror image files; an index catalogue module, for connecting with the interface module and storing the generated index file via an index catalogue structure, wherein the index files are one-to-one correspond to the target mirror image files, and the index file contains the file information of the target mirror image files and the originals files; and a mirror image file system, for connecting with the index catalogue module, and generating a corresponding target mirror image file in the mirror image file system according to the index file in the index catalogue structure and the original file pointed out in the index file.

Description

technical field [0001] The invention relates to the field of computer file systems, in particular to file systems related to file merging operations. Background technique [0002] In order to provide high-quality network services in a complex network environment, websites that provide network services (such as forums, portal websites, online games, videos, etc.) generally build or purchase content distribution networks to accelerate network services. It also reduces the pressure on the source station. [0003] The use of content delivery networks results in access logs being spread across a large number of machines, which need to be sorted and merged. In order to improve the efficiency of sorting and log merging, log files are generally processed at a smaller time granularity, and then the sorted logs are merged, resulting in a large number of log file merging operations. [0004] In the existing file system, to merge two or more files into one file, the content of the fil...

AI Technical Summary

Problems solved by technology

[0008] 1. A large number of IO operations lead to excessive system IP load, which further leads to a decline in server performance

[0009] 2. The merge operation takes a long time, resulting in an increase in system delay

[0010] 3. Most of the time, the system needs to save the files before and after the merge, such as the log system above, which will consume twice the storage space
