Problems solved by technology
[0003] Since the existing off-site data backup method is based on asynchronous database replication, there is usually a certain delay, and the data for a certain period of time (currently generally 30 minutes) before the disaster may not be synchronized to the off-site data center in time. Therefore, Based on the current remote data synchronization method, once a regional disaster occurs, there will be a big problem in switching to a remote data center to provide customers with financial services

The present invention provides a data synchronization method and device, the method comprising: the first data distribution terminal writes the request message into the first local kafka cluster via the first data write terminal, and the first local kafka cluster sends the request message To the second data center, when the first data distribution end receives the response message corresponding to the request message, and receives the confirmation receipt message from the second data center for the request message, write the response message through the first data The input end writes to the first local kafka cluster; furthermore, the first local kafka cluster sends the response message to the second data center, so that the second data center stores the mapping relationship between the request message and the response message. It can be seen that by using the data synchronization method provided by this application, the mapping relationship between the request message and the response message of the local data center can be synchronized to the remote data center in time, thereby ensuring that when a regional disaster occurs, the remote data center can To provide customers with reliable financial services.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a data synchronization method and device. Background technique [0002] At present, banks mostly adopt the construction plan of "same-city dual-active + remote disaster recovery" to ensure the reliability of financial services, that is, to deploy two data centers in the same city that can provide services to the outside world at the same time, and they are mutually backup. In the event of a disaster, another bank can automatically take over all transaction requests from the bank, with no perception of customers and no capital risk. Once a disaster (such as a regional disaster) occurs in two data centers in the same city, it is necessary to switch to the off-site backup data center, and the off-site data center will take over all transaction requests of the bank. [0003] Since the existing off-site data backup method is based on asynchronous database replication, there is usually ...
