DATA SYNCHRONIZATION METHOD, DEVICE AND SYSTEM

Title:

DATA SYNCHRONIZATION METHOD, DEVICE AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/127903

Kind Code:

A1

Abstract:

A data synchronization method, device and system. The data synchronization method comprises: receiving first modified data of a main memory (101); adding the first modified data into an asynchronous message queue (102); and sending the first modified data in the asynchronous message queue to a standby memory through a message sending thread (103). By way of adding modified data in a main memory into an asynchronous message queue and starting one or more message sending threads to send the modified data in the asynchronous message queue to a standby memory, data synchronization between the main memory and the standby memory is not limited by a resource of the main memory. The method reduces the time delay between the main memory and the standby memory during data synchronization by sending data through a plurality of threads.
