[0003] However, when there are multiple machines in the cluster, all machines in the cluster share this cache management table. After the first machine is updated, the cache record status is updated to refresh_finish. When other machines come over, they find that there is no wait_for_refresh data. , the local cache data will not be updated, and there will always be only one machine in the cluster that can refresh the latest cache

Abstract

The invention discloses a data management method and device. The data management method includes the steps that cache records corresponding to identification information of a server are obtained from a cache management table according to the identification information of the server; the cache record in a to-be-refreshed state is obtained from the cache records corresponding to identification information of the server; cache data corresponding to a cache name is refreshed according to the cache name in the cache record in the to-be-refreshed state. Data of the server is identified according to the identification information of the server so that as for static configuration data, each server can have unique configuration, as for dynamic management data, each server can independently refresh corresponding cache data, and refreshing of different servers is not affected.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data management method and device. Background technique [0002] Now, for the local cache management of the application, if it is static data, the memory cache can be used directly, but if there is a possibility of adding or changing in the future, it needs to have a function that takes effect in real time. In addition, the timing of each cache refresh needs to be controllable, otherwise there may be compatibility issues. In the prior art, the above purpose is generally achieved through a cache management table and a scheduled task in a container. Specifically, the scheduled task scans all the data in the table whose state is waiting for refresh (wait_for_refresh), and then obtains the latest data from the storage , update the local cache, and then update the cache status to refresh finish (refresh_finish). [0003] However, when there are multiple machines in the cluste...
