Abstract

The invention discloses a distributed small file system which comprises a client node, a NameNode node, a BackNode node and a DataNode node, the NameNode node is used for managing metadata of a file system, the BackNode node is used as a backup node of the NameNode node, the DataNode node is used for storing real files, the DataNode node is in communication connection with the client node and the NameNode node, and the client node and the NameNode node are in communication connection. The client node is in communication connection with the NameNode node, and the NameNode node is also in communication connection with the BackupNode node. In the implementation process, the nodes can be matched with one another to form a system, the nodes are distinct in responsibility, codes are popular and easy to understand, high-availability architecture design and high expansibility are achieved, and elastic expansion and contraction of the cluster nodes are supported. The NameNode supports a single-machine deployment mode and a cluster deployment mode, and the single-machine mode can meet the storage requirements of a large number of small files of small and medium-sized companies. The cluster mode can support the storage requirements of massive small files of medium and large companies.

Description

technical field [0001] The invention belongs to the technical field of file storage systems, in particular to a distributed small file system. Background technique [0002] Most of the existing distributed storage systems are developed and implemented in C language and Go language. It cannot be well compatible in the application field of the huge Java language technology stack in the ecosystem. It is difficult for Java developers to get started, and it is difficult for small and medium-sized companies to maintain. High system latency and frequent system crashes. It cannot provide high concurrency, high stability, and high availability system output, which increases the maintenance cost of enterprise use. There are certain bottlenecks in file storage and transmission, and it is impossible to expand horizontally. At the level of system use, problems such as obscure user manuals and lack of documentation make it difficult to use, and usually require professional guidance to ...
