Abstract

The invention discloses a data synchronization method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of storing to-be-updated service data into a cache; storing the changed service data in the cache into a current sliding window; and creating a new sliding window, taking the new sliding window as a current sliding window, and synchronizing the service data in the original sliding window to the database. According to the embodiment, the problems of high use cost and data loss can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for synchronizing data. Background technique [0002] At present, it is often necessary to monitor and count a large amount of real-time data and generate real-time reports, such as real-time statistics on the delivery order volume of a sorting center in a certain period of time. If you update the relevant records in the database every time an order is issued, since the sorting center operates very frequently, in order to count a large number of indicators, it will frequently update the relevant tables in the database, which will put a lot of pressure on the database and cause the CPU of the database to be too high. High, master-slave delay and other issues. [0003] For the above problems, there are currently two solutions: first, the database is divided into databases and tables, that is, multiple databases are used to store data to reduce the pressure on...
