Problems solved by technology

This file synchronization method is an asynchronous method. The asynchronous method will cause the problem of file synchronization delay. That is, if the user uploads a file and immediately initiates a download request on the data storage server that has not completed file synchronization, the file will not be found. The phenomenon

Embodiment

[0025] like figure 2 As shown, a distributed file system based on resource locator jumps, including

[0026] The resource locator side includes one or more locating servers, each locating server is independent of each other, and mainly plays a scheduling role, processes requests transmitted by clients and monitors the operation status of the file storage server.

[0027] The data storage server side includes one or more data storage server groups, and each group has one or more data storage nodes, which mainly complete data storage and synchronization, and can actively connect to resource locators. The files stored by the data storage nodes of the same group are consistent, and the data storage nodes of different groups are independent of each other.

[0028] The client, the user's operation portal, connects to the resource locator, and the resource locator allocates available data storage nodes for it.

[0029] A data synchronization method of a distributed file system bas...

Abstract

The invention discloses a distributed file system on the basis of jump of a resource locator and a data synchronization method thereof and relates to the field of data storage. The system comprises a resource locator side, a data storage server side and a client. The resource locator side is mainly used for doing dispatching work, only records state information and a grouping condition of the data storage server side in an internal memory and is a hub for interaction of the client and the data storage server side. According to the system, by adopting a mode of carrying out grouped storage at the data storage server side to improve reliability of data and utilizing the resource locator to solve the problem of delay of file synchronization, which is caused by asynchronization synchronization, not only is safety of user files ensured, but also the problem of being unable to find downloaded files is solved and better experience is brought to users.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a resource locator-based jump distributed file system and a data synchronization method thereof. Background technique [0002] Nowadays, human beings have entered the era of informatization, and the total amount of information is growing exponentially. The information systems represented by social networking sites and cloud computing have reached the PB level of data to be processed, and are developing towards the EB level. , in order to solve the growing demand for massive data storage, distributed file storage has gradually become a research hotspot. The distributed file storage system includes multiple data storage servers. In order to improve data reliability, these storage servers will perform synchronous replication according to the file upload records. This file synchronization method is an asynchronous method, and the asynchronous method will cause the problem of file synchro...
