Data processing method and device, electronic equipment and storage medium

Abstract

The invention relates to a data processing method and device, electronic equipment and a storage medium, and the method comprises the steps: generating second cache data corresponding to second data and storing the second cache data in a preset cache under the condition of determining that the first data stored in a database is updated into the second data, further storing first cache data corresponding to the first data in the preset cache; and under the condition that the number of the to-be-responded information acquisition requests exceeds a number threshold value, using the second cache data to respond to a preset number of information acquisition requests, and using the first cache data to respond to the remaining information acquisition requests. According to the scheme, cache avalanche possibly caused by processing a large number of requests within a short time can be effectively avoided, and the operation stability of a database system is improved to a certain extent.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a data processing method, device, electronic device, and storage medium. Background technique [0002] At this stage, various network business systems such as online e-commerce, live broadcast platforms, and data management platforms usually use databases (Database, DB) to store business data during business operations. In the case of a large amount of business data, in order to avoid problems such as long processing time and database damage that may be caused by direct operation of the database, a cache is usually set between the network business system and the database. [0003] However, after the cached data stored in the cache is updated along with the data in the database, if the cache device receives a large number of information acquisition requests in a short period of time, it usually cannot process the requests in a timely and efficient manner. Taking the p...

[0003] However, after the cached data stored in the cache is updated with the data in the database, if the cache device receives a large number of information acquisition requests in a short period of time, it usually cannot process the requests in a timely and efficient manner.

Taking the project related to the timed rush-buying activity as an example, after deleting the permission data of the relevant personnel of the rush-buying activity in the project, if a large number of commodity rush-buying requests related to the rush-buying activity are received, since the above-mentioned permission data, the above-mentioned permission information will be temporarily pulled from the database multiple times in response to the commodity snap-up request, which may cause the database to receive too many information pull requests in a short period of time, and even cause a cache avalanche. Therefore, the stability of the database system lower
