Data processing method and device, electronic equipment and storage medium

Abstract

The invention discloses a data processing method and device, electronic equipment and a storage medium, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of receiving a data request, obtaining a data identifier in the data request to query corresponding target data from a cache, returning the target data, and triggering an update operation of the target data; in response to the updating operation, an expiration timestamp and an updating threshold value of the target data are obtained, and the updating threshold value is determined from an updating time interval corresponding to the expiration timestamp based on the attribute parameters of the target data; and calculating the duration between the expired timestamp and the current time, determining that the duration is smaller than an updating threshold value, and calling a preset data updating thread to update the target data in the cache. According to the embodiment, the problem that the performance of a service system is reduced due to the fact that the data is updated after the data in the cache arrives at the expiration time in a high-concurrency scene can be solved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a data processing method, apparatus, electronic device and storage medium. Background technique [0002] With the rapid development of the Internet, high concurrency has become a common scenario for business systems to process business data, and the expired refresh cache mechanism is a common method in high concurrency scenarios. The expired refresh cache mechanism means that the expiration time is set when the data in the cache is stored, and the data is updated when the expiration time is reached. However, during the high-concurrency stress test of the business system, it was found that after the data in the cache reaches the expiration time, even if the downstream data source is fully optimized so that the data can be updated in time, the efficiency of data request and response will still be reduced, which will lead to the failure of the business system.
