Problems solved by technology

[0003] Today, most distributed systems still adopt a centralized design idea, that is, coordinate and control the operation of the entire system through a central node. The biggest problem lies in the safety and bottleneck of the central node. If there is a problem with the central node, it will directly affect the entire system. normal operation of the system
[0004] Therefore, the current distributed system has a higher probability of failure

Embodiment Construction

[0045] The present invention will be described in detail below through the embodiments in conjunction with the accompanying drawings.

[0046] The decentralized distributed data synchronization method proposed in this embodiment mainly includes two parts: the automatic selection of the synchronization initiator and the synchronization mode based on the "request / response" structure. The overall process is as follows: figure 1 shown.

[0047] When the external application calls the interface to write data to the distributed node, select the appropriate distributed node through the load balancing strategy to perform data preprocessing and initiate a synchronization request, while the remaining nodes respond to the synchronization request and implement the corresponding data operation. Complete data synchronization. Specifically

[0048] 1. Decentralization: There is no central node in this embodiment, and each valid node is equal, that is, it can be used as a synchronization in...

Abstract

The invention belongs to the field of distributed storage, and discloses a decentralized distributed data synchronization method, distributed nodes and a decentralized distributed data synchronizationsystem. The method comprises the steps of automatically selecting relatively idle nodes as initiating ends of synchronization requests through load monitoring of distributed nodes, performing validity judgment and preprocessing on data writing, and distributing synchronization information, thereby improving the data processing capability of the whole system and enhancing the availability and theflexibility. A synchronization mode based on a request / response structure is designed and adopted, and the whole process of request sending, data writing and result feedback between the synchronization initiating end and the response end can be achieved only through one-time interaction. The method can efficiently and reliably complete distribution, processing and feedback of the synchronization information between the distributed nodes, and the purpose of real-time synchronization of system data is achieved.

Description

technical field [0001] The invention belongs to the field of distributed storage, and relates to a distributed data synchronization method, a distributed node and a system. Background technique [0002] With the rapid development of network and information technology, distributed technology is becoming more and more mature, and the application of distributed systems is becoming more and more extensive. In a distributed system, how to realize real-time information sharing among distributed nodes and ensure the data consistency of the system has always been a hot issue in this field. [0003] Today, most distributed systems still adopt a centralized design idea, that is, coordinate and control the operation of the entire system through a central node. The biggest problem lies in the safety and bottleneck of the central node. If there is a problem with the central node, it will directly affect the entire system. normal operation of the system. [0004] Therefore, the current ...
