Abstract

The invention discloses a data synchronization method and system, and belongs to the technical field of data synchronization. The method comprises the following steps: S1: obtaining a data operation request and the query time of data to be operated; S2: according to the corresponding query time, containing the data operation request in a request batch of a corresponding time slot; and S3: in a first storage unit, inquiring to obtain a data size contained in the time slot corresponding to one request batch, judging whether the data size is greater than a preset data size or not, dividing the data to be operated into a plurality of data batches by the preset data size as a unit if the data size is greater than the preset data size, transmitting each data batch to a second storage unit, and otherwise, transmitting all data to be operated to the second storage unit. The system comprises a first storage unit, a setting unit, an acquisition unit, a division unit, a query unit, a judgment unit and a processing unit. The technical scheme has the beneficial effects that query response speed is improved, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of data synchronization, in particular to a data synchronization method and system. Background technique [0002] With the development of e-commerce, more and more people choose to conduct daily shopping transactions and other various types of transactions on online trading platforms. With the continuous increase of network transaction volume, the amount of transaction data stored in the e-commerce database is also gradually increasing. In this case, if a merchant needs to query or download transaction data, it usually faces a huge amount of data storage, which will take up more space in the database due to various reasons (for example, the amount of data to be searched is too large) Query statements, or the amount of downloaded data is too large to occupy too much hardware resources) makes the database respond very slowly when receiving queries or download requests, and even crashes, thus reducing ...
