Abstract

The invention discloses a distributed file system which comprises a distributed database system, the distributed database system comprises a database and table dividing module, and the database and table dividing module is used for dispersing database tables with the data size exceeding a set threshold value into a plurality of distributed database systems. The distributed database system of the distributed file system can be used for solving the expansibility problem of a relational database, and has the characteristics of light weight (stateless), flexibility, stability, high efficiency and the like; the distributed database system is compatible with common database protocols and grammars, supports the characteristics of database division, table division, smooth capacity expansion, service lifting and distribution, transparent read-write separation, distributed transactions and the like, and has the operation and maintenance management and control capability of the whole life cycle of the distributed database. A main application scene of the distributed database system is applied to large-scale online data operation, the operation efficiency is improved to the maximum in a service fitting splitting mode, and the requirement of online services of a user for a relational database is effectively met.

Description

technical field [0001] The invention particularly relates to a distributed file system. Background technique [0002] The design of the distributed file system is based on the client / server model. A typical network may include multiple servers accessed by multiple users. In addition, the peer-to-peer feature allows some systems to perform the dual roles of client and server. The computer manages and stores data through the file system, and the data that can be obtained increases exponentially. Simply by increasing the number of hard disks to expand the storage capacity of the computer file system, in terms of capacity size, capacity growth speed, data backup, and data security The performance in other aspects is unsatisfactory. [0003] The distributed file system can effectively solve the problem of data storage and management: a file system fixed at a certain location can be extended to any number of locations and multiple file systems, and many nodes form a file system...
