Abstract

The invention discloses a method and apparatus for updating dirty data. The method comprises the following steps: acquiring an attribute name and a key value of an object, identifying data corresponding to the key value in a cache according to the attribute name of the object, when the data corresponding to the key value in the cache are identified as dirty data according to the attribute name of the object, acquiring the data corresponding to the key value from a database according to the key value, and updating the data in the cache according to the data corresponding to the key value and acquired from the database. By adoption of the above-mentioned method, even if the dirty data are present in the cache, the cache does not need to be emptied anymore, the dirty data in the cache can be identified, and smooth update is carried out on the identified dirty data, therefore the problem of service breakdown caused by the overlarge pressure of the database can be effectively solved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for updating dirty data. Background technique [0002] With the continuous development of computer technology, more and more software and systems are developed using object-oriented languages. For example, the development of large-scale Web systems is generally developed using object-oriented languages. [0003] At present, due to the large number of users using the large-scale Web system, and the low read and write performance of the disk for storing data, this will inevitably lead to a particularly high load on the server. Therefore, it is necessary to use memory as a cache to improve the performance of the entire large-scale Web system , and, an object-oriented caching system is established for storing the data of the large-scale Web system in the cache and obtaining data from the cache and providing it to the large-scale Web system.
