Problems solved by technology

[0003] Current research on file access methods focuses on the storage of massive small files and fast access. For example, Taobao’s TFS can provide fast access to small files, but cannot quickly access large files. Files are stored in data nodes as large files, which results in slower access for small files

Embodiment 1

[0049]This embodiment discloses a storage method for small files and large files, the method is based on such as figure 1 Realized on the basis of the shown user equipment, cache server, management server and data server; where

[0050] User equipment: used to create files, record logs, and search logs; determine whether the file to be created is a large file or a small file according to the first threshold, and add identifying prefixes for identifying large files and small files to the created file name L and S, where the user equipment adds L before the file name of the large file to be created, and the user equipment adds S before the file name of the small file to be created, and sends a new file creation request instruction to the cache server. It is used to determine whether the file corresponding to the file name to be accessed is a large file or a small file according to the search log, and then add an identifying prefix used to identify the large file and small file t...

Abstract

The invention discloses a method for storing and accessing small files and large files. In the storage process, the invention stores small files and commonly used large files in a cache server. The specific steps of the access method are as follows: the user equipment requests the file name according to the user Add an identifying prefix in front of it; after receiving the request, the cache server judges whether it is a large file or a small file according to the prefix identifier of the file name; if the requested file is a small file, the cache server searches the local small file storage area, if the requested file is For large files, the cache server searches the local cache area; if the cache server has the file, the user is guided to access the file; if the cache server does not have the file and the user request is a large file, the user request is sent to the management server. Large files are stored in the cache server, and the identification prefix judgment of the file name is introduced, which can effectively improve the efficiency of user access to files and reduce user waiting time.

Description

technical field [0001] The invention relates to the field of file access, in particular to a method for storing and accessing small files and large files. Background technique [0002] With the development of society, a large amount of data is generated in people's daily life and work. These data are mainly small files such as text, documents, and Excel prefixes, but also include some large files such as video files and high-definition picture files. According to the habit, people usually access the most small files and some large files. Therefore, how to efficiently store these two types of files and enable users to quickly access these two types of files has become a difficult problem in the current file access field. [0003] Current research on file access methods focuses on the storage of massive small files and fast access. For example, Taobao’s TFS can provide fast access to small files, but cannot quickly access large files. Files are stored in data nodes as if the...
