Embodiment Construction

[0024] Hereinafter, the implementation of the data synchronization method and device according to the embodiments of the present application will be described in detail in conjunction with the accompanying drawings.

[0025] First, introduce the network environment to which the data synchronization method and device of the embodiment of the present application can be applied, which may include: at least two data centers, each of which performs the same or different data processing; and needs to obtain itself The data is synchronized to other data centers.

[0026] exist Figure 1a In the shown network environment example, three data centers including data center A, data center B, and data center C are connected to each other for synchronous data interaction.

[0027] For the convenience of understanding, the embodiment of this application will take the relevant location data of the recommended data as an example as the data synchronized between the data centers. Of course, thi...

Abstract

The invention discloses a data synchronization method of which each data center is provided with a data sheet collection and a backup file. The method further comprises the following steps: writing data to a data sheet corresponding to a first data centre in the local data table collection of the first data centre when the data center is determined to write the data, and synchronously writing the written data into the local backup file of the first data centre; and transmitting the backup file to other data centers once the time for synchronizing arrives, so that other data centers can update the local data table collection of other data centers according to the backup file. The invention also discloses a data synchronization device. With the adoption of the method and device, the problem that the synchronizing data is lost, which is caused by performing synchronizing and deleting on the data disorderly can be solved.

Description

technical field [0001] The present application relates to data processing technologies, and in particular to a data synchronization method and device. Background technique [0002] In the P4P (Pay For Performance) system of some e-commerce websites, the payment is based on the performance, that is, when the advertisement is charged, only when the user clicks on the advertisement will the advertisement be deducted. [0003] In the existing P4P system, the click data of advertisements of foreign users is generally processed by foreign data centers set up in foreign countries such as the United States, while the domestic data centers set up in China mainly deal with the account operations of users and customer service personnel for advertising merchants Data, such as modifying the account amount of the advertiser, etc. [0004] The P4P system internally maintains the location information of each advertisement in the P4P system. For each advertisement, whether it is the deduct...
