Problems solved by technology
Among them, the method of restarting the server is too troublesome and may cause external access failure; the method of regularly querying the data content of the database by the server requires the server to regularly read the data in the local cache from the local cache and compare them with the database one by one. Comparing the obtained data will waste a lot of server resources, and the operation of reading and writing the data in the cache too frequently will also increase the probability of data errors; the method of pushing messages needs to maintain a push mechanism. high maintenance cost

The invention discloses a cache data updating method, device and system, which relate to the field of data technology, and the main purpose is to make the maintenance cost and occupied resources lower and the operation simple under the premise of ensuring normal access to data by applications. The main technical solution is: when the business server starts, obtain and load from the database server the cached data that needs to be cached in its local cache and the cached version information table corresponding to the cached data; determine whether the cached version information of different data types corresponds to the corresponding The database version information of the data in the database server is consistent; if it is determined to be inconsistent, the cached data and the cached version information table are updated. The database server generates and saves the database version information table, and sends the cached data and the cached version information table required by the business server to the business server when the business server starts. The present invention is mainly used in the process of updating the local cache of the service server.
Description
technical field [0001] The present invention relates to the field of data technology, in particular to a method, device and system for caching data update. Background technique [0002] With the development of the Internet and smart terminals, the use of applications is becoming more and more diverse. When an application is deployed on multiple servers, the multiple servers generally need to share the same set of data storage databases to ensure the normal operation of the application. . In multi-server mode, in order to improve data access performance, for those data with small data volume, infrequent updates and large access volume, such as dictionary tables, parameter tables, area information, etc., it is generally used to store such data in in the server's local cache. When storing data in the local cache of the server, it is necessary to consider the consistency between the data cached locally on the server and the data in the database. For example, if the data in the...
