Embodiment Construction

[0014] The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The technical solution provided by the embodiment of the present invention is to perform data synchronization between one source data terminal and two destination data terminals (target data terminal A and destination data terminal B).

[0015] The main process of this implementation plan is as follows: figure 1 Shown include:

[0016] Step 101: Data changes occur at the source data end.

[0017] Data changes occur on the source data end, and this is used as a starting condition to trigger data synchronization between the source data end and the destination data end.

[0018] Step 102: Collect the data change information of the source data terminal, judge whether there is a synchronization exception, if there is a synchronization exception, execute step 104, otherwise execute step 103.

[0019] Step 103: Send the data ch...

Abstract

The invention relates to the technical field of data synchronization and provides a method and device for synchronizing data aiming at solving the problems in the prior art that the data synchronization is easy to fail and further the data are lost under the condition of the severe work environment. The method comprises the following steps of: in the process that the source data end and the data end are subjected to the data synchronization, writing data to be synchronized in the source data end in a safety cache when the synchronization is abnormal; and transmitting the data to be synchronized in the safety cache to the target data end when the synchronous abnormality is restored. By adopting a safety cache mechanism, the failure of the data synchronization can be avoided under the condition of the severe work environment and the further the data can be prevented from being lost.

Description

technical field [0001] The present invention relates to the technical field of data synchronization, in particular to a data synchronization method and device. Background technique [0002] At present, many businesses in various high-end fields around the world use databases when processing huge data, but it is difficult for a single database to meet multi-point usage, which will increase the pressure on the database. This requires the use of data synchronization technology to synchronize newly changed data from one database to other databases of the same purpose (such as synchronizing the data of the local database to other multiple regional databases for one-to-many synchronization). [0003] The current data synchronization technology cannot guarantee the reliability of data synchronization when the link is abnormal or the destination is abnormal. It can be seen that in the existing technology, data synchronization failure is easy to occur in the case of a bad working env...
