Abstract

The embodiment of the invention discloses a data synchronization method and device, electronic equipment and a computer readable medium. A specific embodiment of the method comprises the following steps: selecting data identifiers meeting a preset condition from a non-local cache data identifier set corresponding to a data operation request set received by a server within a target time period to obtain a target data identifier set; and synchronizing the target data identifier set to other servers in the distributed server cluster, wherein the target data identifier set is used for storing corresponding data in local caches corresponding to other servers. According to the method, the probability that the data operation request hits the data in the local cache is improved, and the response speed of the cluster is also improved.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular, to a data synchronization method, device, electronic equipment, and computer-readable medium. Background technique [0002] The use of local cache can effectively improve the performance of the system while reducing the dependence of high concurrency scenarios on databases such as redis. Related local cache open source frameworks include guava, ehcache, etc. [0003] However, the inventors found that these open source frameworks often have the following technical problems when applied: [0004] First, these frameworks perform data caching on a single device, which is difficult to directly apply to device clusters. [0005] Second, since these frameworks cache data on a single device, each node only caches data in isolation even if it is applied to a cluster forcibly. This will lead to the fact that the local cache of each node does not store the ...
