Transaction level-based data synchronizing method, device thereof and system thereof

Abstract

The embodiment of the invention discloses a transaction level-based data synchronizing method, a device thereof and a system thereof. The method comprises the steps of: when a transaction change is generated by a data source generating a unique and ordered transaction version identification for the transaction change; recoding a corresponding relationship between the changed data generated by thetransaction change and the transaction version identification; and when the condition that the data needs to be synchronized is achieved, returning incremental data change information to a synchronizing party according to the different between the current transaction version identifications of the synchronizing party obtained from a data synchronizing request transmitted by the synchronizing party and the unique and ordered transaction version identification which correspond to the data in the date source, so that the synchronizing party can synchronize the data according to the incremental data change information. After the embodiment of the invention is used, the synchronizing party can keep the integrality of the synchronized data transaction in the process of local updating, i.e. or all the data modified in the same transaction in the data source is successfully synchronized to the far-end synchronizing party, or all the data is not completely synchronized to the far-end synchronizing party, so that the data of the synchronizing party is kept to be integrated in the transaction all the time, and an intermediate state can be avoided.

Description

A transaction-level data synchronization method, device and system technical field The present invention relates to the technical field of data synchronization, in particular to a transaction-level data synchronization method, device and system. Background technique With the increase of business capacity, more and more application systems adopt distributed design to utilize the computing power of multiple computers. In many distributed systems, data synchronization between multiple nodes is involved. Therefore, data synchronization scheme is one of the most important topics in distributed system design. For example, in a telecommunications management system, key data such as network topology is maintained by the topology management subsystem, and copies need to be cached in multiple subsystems, which involves data synchronization. At the same time, the automatic configuration function in the configuration management subsystem (Conf.Manager) will rely on changes in the to...

Problems solved by technology

Obviously, since the synchronizing party performs various operations in sequence, there will be some intermediate states. In these intermediate states, the data of the synchronizing party is incomplete, which may cause business interruption and other phenomena.

In addition, in some extreme cases, if due to problems such as network delays, the data generated first reaches the sync side, it may cause the sync side to be unable to process the data, and the data will be discarded, resulting in synchronization failure.
