Abstract

An embodiment of the invention provides a cross-datacenter data synchronization method and device. The method specifically includes: collecting key value pair data of to-be-synchronized datacenters; utilizing a distributed computational frame to perform consistency checking of the key value pair data of the to-be-synchronized datacenter so as to obtain consistent or inconsistent testing results. By the method and device, times of access to each datacenter can be decreased, so that online access pressure on each datacenter can be relieved; besides, cross-datacenter data synchronization efficiency can be increased, and computational resources of each datacenter can be avoided being occupied, so that performance of each datacenter is avoided being affected.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to a data synchronization method and device across data centers. Background technique [0002] With the advent of the Internet era, Internet users all over the world conduct various interactions every day and produce various data at any time. The amount of these data is several times the amount of data in the stand-alone era. In order to store these data, various Internet companies have established huge IDCs (Internet Data Centers, Internet Data Centers) all over the world, and the number of hosts in a single data center ranges from hundreds to tens of thousands. [0003] In order to achieve seamless connection between data centers when data centers fail, data synchronization across data centers becomes particularly important. [0004] The existing cross-data center data synchronization solution is usually completed by each data center based on mutual access between dat...
