A data synchronization method, device and system

Abstract

The embodiment of the invention discloses a data synchronizing method, device and system, which are applied to the technical field of data information processing. In the embodiment of the invention, a data synchronizing subsystem stores received recommendation data in a cache subsystem, and reads and synchronizes the stored data to a recommendation engine according a second period. The recommendation data received by the data synchronizing subsystem comprises a first type recommendation data transmitted by an application putting subsystem according to a first period, and / or second type recommendation data transmitted in real time, wherein the second period is smaller the first period. According to the method in the embodiment of the invention, the first type recommendation data can be synchronized with the smaller second period without changing an existing application putting subsystem, so that the synchronizing frequency of the first type recommendation data is increased. Alternatively, only the existing application putting subsystem needs to be changed to transmit in real time during transmission of the second type recommendation data, and the second type recommendation data is synchronized with the second period, so that the second type recommendation data is synchronized at an appropriate frequency.

Description

Technical field [0001] The present invention relates to the technical field of data information processing, in particular to a data synchronization method, device and system. Background technique [0002] In existing recommendation systems (such as advertising systems, news recommendation systems, etc.), businesses can send data that needs to be recommended to various user terminals through the recommendation system, either directionally or non-directionally, so as to promote a certain product or inform a certain Some information and other purposes. In the specific implementation process, the recommendation system can include an application delivery subsystem and a recommendation engine. The application delivery subsystem synchronizes the recommendation data to the recommendation engine. The recommendation engine determines which recommendation data is delivered to which user terminals. Finally, the application delivery subsystem will According to the information determined by t...

Problems solved by technology

[0003] In the prior art, when the application delivery subsystem synchronizes the recommendation data, it directly forms a file with the recommendation data at a certain period, and sends the formed file to the recommendation engine. Generally, the cycle of the application delivery subsystem to synchronize the recommendation data is relatively short. Long, so that the recommendation engine cannot grasp the latest situation of the recommended data as soon as possible, but if the synchronization cycle is reduced, it will have a certain impact on other processing functions of the application delivery subsystem
