Abstract

The present invention relates to a method for synchronizing distributed database data, comprising: step S1, an extension uploads received data to a central server; step S2, the central server selects an extension to be synchronized according to the type of current data content; step S3, the central The server selects the extension with the minimum amount of synchronous data queue among the extensions of each extension group as the current data synchronization extension; step S4, the central server obtains the current data urgency, selects the current data synchronization priority according to the urgency, and the synchronization extension Reorder the data synchronization order in the data synchronization queue; step S5, after the central server central server synchronizes the current data to the extension to be synchronized, update the current data timestamp, and repeat steps S3‑S4 until each extension group has the current data content synchronized . The invention adjusts the sequence of synchronous data arrangement of each extension by setting a central server, thereby improving the efficiency of data synchronization.

Description

technical field [0001] The invention relates to the field of data synchronization, in particular to a distributed database data synchronization method. Background technique [0002] An important issue in network system development is how to configure different devices to share resources. The actual implementation depends to a large extent on the functions of the network, which can be generally divided into two categories: centralized systems and distributed systems. The centralized system has many terminals, resulting in slow response and low efficiency. Distributed systems have low cost, strong scalability and processing capabilities. With the rise of cloud computing, the demand for massive data storage and management is also increasing. Under such a trend, many large-scale distributed databases for massive data management provide massive data storage and management capabilities by using commercial hardware to build large-scale server clusters. [0003] At present, in pr...
