Abstract

Embodiments of the invention disclose a cached data refreshing method and device. The method comprises the following steps of: obtaining a cache task of an Oracle database; refreshing to-be-cached data corresponding to the cache task to an application database Redis, and generating a data refreshing signal key corresponding to the to-be-cached data; and when the to-be-cached data is refreshed to an internal cache of a business processing program, writing an ID of the business processing program into a value of the key. According to the method, an Oracle database and an application database Redis+-based high-class calculation platform IBM Streams is built on the basis of an SOA architecture, and when the cached data is refreshed to the Redis, the refreshing signal key is automatically generated, so that the ID is written into the value of the key when the internal cache of the business processing program is refreshed, the persistence and synchronization of the cached data are realized,repeated program cache refreshing is avoided and the resource waste is decreased.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a cache data refresh method and device. Background technique [0002] Cache is an in-memory database that resides in memory, and the reading speed of memory is much faster than the speed at which programs can read data from disk. When designing a program, the use of cache is often considered. Putting frequently accessed data on the memory can improve the speed of accessing data, and at the same time reduce the pressure on the disk or database. [0003] At present, the caching strategy of Memcached is usually adopted. Memcached is a high-performance distributed memory object caching system for dynamic web applications to reduce database load. It improves the speed of dynamic, database-driven websites by caching data and objects in memory to reduce the number of database reads. In order to improve the speed of data storage, Memcached will automa...
