Problems solved by technology

However, distributed databases have never had a complete management system
If there is no good management mechanism, the traffic cannot be allocated reasonably, and it will also lead to the phenomenon that the database server responds to a drop or even crashes when there is a large traffic request and storage. Therefore, a distributed database needs a mature management system, based on the original server management. It cannot meet the current needs, and the new needs must be centralized, grouped, and automated to manage the database server

Embodiment Construction

[0024] A further detailed description of the distributed database concurrent storage virtual request storage mechanism will be made below in conjunction with the accompanying drawings.

[0025] like figure 1 As shown in the figure, when multiple users access the system concurrently, the web server only responds to the corresponding web application. Separating the data storage business to reduce the load on the server is actually a kind of load balancing. When it comes to data storage, an access control server will be involved in the collaborative effort.

[0026] like figure 2 As shown, when multiple users access the system concurrently and request to store data, according to the number on the figure, the specific steps of this mechanism are as follows:

[0027] 1. Multiple clients send http requests concurrently, some of which include data storage requests.

[0028] 2. The web application server receives http requests from multiple clients, and filters out user units tha...

Abstract

A system of a distributed database concurrence storage virtual request mechanism comprises a client for sending storage requests, a web application server, an access control server and a distributed database cluster. Based on the system, a distributed database storage management mechanism scheme is put forward, the mechanism particularly considers the flow request required by the number of concurrence users to reasonably store the user data flow in a distributed manner, that is, under the framework of the cloud database, the user data flow is distributed to the most reasonable database cluster for storage according to the current network load and the current database concurrence connected load. The mechanism realizes management of the distributed database cluster by utilizing the access control server, and an ACK (acknowledgement character) information packet fed back by the database cluster calculates the optimized storage strategy and completes final data storage through a corresponding flexible algorithm.

Description

technical field [0001] The invention relates to the field of network technology, in particular to the field of distributed database storage management and security mechanism for big data distribution, rational allocation of network resources, improvement of network throughput, and reduction of network congestion. Background technique [0002] In today's Internet era of massive information, databases have been widely used in various industries from simple storage of various data forms to massive data storage. Database storage is often the bottleneck of website access, especially the traditional database storage method is too simplistic, too centralized management causes a large amount of data accumulation, and due to the centralized management, the access pressure is very high, which is not only reflected in the connections supported by the database connection pool, but also in On sudden large traffic and huge I / O business request visits, once this phenomenon occurs, the resp...
