Distributed file system and method for storing data and providing services by utilizing same

Abstract

The invention discloses a distributed file system which comprises a metadata server, a data server, a file system client and an application program client, wherein the metadata server is used for saving a list of nodes of the data server, which correspond to all user identifiers, and the corresponding relationship between the nodes and the identifiers, maintaining the load situation of each node, guiding the data server to implement the operations of load balancing and redundancy recovery and representing the load situation by data size; the data server is used for storing data of users and corresponding metadata of the users, leading the data of each user to be stored under an individual directory, and using the identifiers to differentiate the directories; the file system client is used for forming a local file directory and forwarding the operations to the corresponding data server; and the application program client is used for leading the user to access the file system through the file directory formed by the file system client and further providing an application program for the user. The invention further provides a method for storing the data and providing the services by utilizing the system. By adopting the system and the method, the efficiency of storing the data of the individual users can be improved.

Description

technical field [0001] The invention relates to the file system field of an operating system, in particular to a distributed file system serving a large number of individual users and a method for using it to store individual user data and provide services for individual users. Background technique [0002] With the development of cloud computing technology and mobile Internet technology, the storage location of more and more users' personal data has been transferred from local devices (such as desktops, netbooks, smart phones, etc.) to remote servers. This brings a lot of convenience to users. [0003] First of all, such a storage model creates opportunities for synchronization of data on different devices. User data such as documents, pictures, music, etc. may be created or generated on a desktop computer, but also want to be viewed or modified on a netbook or smart phone. Since the data is always available on the remote server, the application can automatically synchron...

AI Technical Summary

Problems solved by technology

Its problem is mainly that the data in the search engine field is characterized by a large amount of index and cache data that are written at one time, and the modification method is mainly based on appending. When dealing with the personal data of a large number of users that needs to be rewritten frequently, the efficiency will be relatively low.
