Embodiment Construction

[0042] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0043] Such as figure 1 A schematic structural diagram of a distributed storage system based on OSGI in this embodiment is shown. The OSGI is a JAVA modular specification, and the distributed storage includes a client, a server, and a node server.

[0044] Both the server and the node server are deployed in the OSGI container, so that the server and the node server can be dynamically installed, uninstalled, started and stopped.

[0045] The client sends the data to be stored or read data request to the server through SOCKET.

[0046] The server sends the data to be stored or read data request to each node server through SOCKET.

[0047] The node server can be increased arbitrarily by adding servers.

[0048] figure 2 The flow chart of data storage is shown. In this embodiment, the client generates JAVA object data, and at the same time generates the...

Abstract

The invention relates to a distributed data storage method based on OSGI, comprising the following steps: generating client data; transmitting the data to a server through a Socket; generating unique ID of sequence data by the server; storing the data in a disk and synchronously transmitting the data to a node server by the server; and reading the data and simultaneously reading data from each node server by the client. The method uses an OSGI frame, and the data is stored through one client and a plurality of node servers, so that the distributed data storage method based on OSGI enables a program to have characteristics of uniform modularized construction and management, and behaviors of being pluggable, accumulated and dynamically changed and extended, the program can be dynamically installed, uninstalled, started and stopped, simultaneously, the distributed storage method effectively improves data security and integrity, reads the data quickly, and solves the bottleneck of slow data reading speed caused by frequent reading and writing operations on the disk while reading and writing mass data.

Description

technical field [0001] The invention relates to an OSGI-based distributed data storage method, in particular to a method for realizing massive data distributed storage by using OSGI in JAVA as a technical means. Background technique [0002] With the continuous development of technology, the demand for data storage increases. The system not only requires the ability to read and write data quickly, but also requires the system to not only ensure data security and data integrity, but also to ensure that the system can run uninterrupted for several years. In this way, the system must be required It is highly dynamic and can complete system module installation, uninstallation, and update operations in the running state. The traditional development model is difficult to dynamically modify and change the behavior of the system. At the same time, the traditional data reading and writing method, due to the bottleneck of disk IO, is difficult to ensure data security, data integrity a...
