Abstract

The invention discloses a data synchronous updating method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of obtaining latest datacorresponding to cache data from a database when it is monitored that the database data corresponding to the cache data is updated; and updating the cache data according to the obtained latest data.According to the embodiment, the problem that when multiple service systems acquire the same data, data synchronization of all service systems is difficult after data updating is solved, the data canbe read quickly and efficiently, the network overhead and time consumption are reduced, the risk of data reading timeout when the data size is large is reduced, the system stability is guaranteed, andthe pressure of database connection can be reduced while data isolation is achieved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for synchronously updating data. Background technique [0002] In daily development, you will encounter this situation: some data rarely changes, but needs to be modified occasionally according to business conditions. For example, the system template data in the page decoration system will be frequently used by users during the page decoration process. The system templates will not be changed frequently, but occasionally adjusted according to business needs. Moreover, the data size of these system templates ranges from tens of kb (kilobytes) to hundreds of kb, and it is best to be cached to prevent frequent database queries and put pressure on the database. [0003] These data usually have the following characteristics: First, the data does not change frequently, but occasionally changes, so the data cannot be regarded as a purely static configuration. Once...
