[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...

The invention discloses a storage and access method of small files and large files. The storage and access method is characterized in that in the storage process, the small files and the common large files are stored in a caching server. The access method comprises the specific steps that user equipment adds identifying prefixes at the front of the file names according to a user request; after receiving the request, the caching server judges whether the files are large files or small files according to prefixed identifiers of the file names; if the requested files are small files, the caching server searches local small-file storage areas, and if the requested files are large files, the caching server searches local caching areas; if the caching server has the files, the user is guided to access the files, and if the caching server does not have the files and the files requested by the user are large files, the user request is sent to a management server. The storage and access method disclosed by the invention has the advantages that the small files and the common large files are stored in the caching server and the identifying prefixes of the file names are introduced for judgment, so that the efficiency of access of the user to the files can be effectively improved, and the waiting time of the user can be reduced.
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...
