Data processing method and device and storage medium

Abstract

The invention provides a data processing method and device and a storage medium. The data processing method comprises the steps that a data processing device obtains data corresponding to a data request from a physical library and a cache library based on the data request sent by a client, and compares the corresponding data in the physical library with the corresponding data in the cache librarythrough a data comparison algorithm to obtain difference data blocks in the physical library and the cache library. And according to the difference type of the difference data block, carrying out datarestoration on the difference data block in the cache library, so that the data of the physical library and the cache library are kept consistent. According to the method, the difference data can bequickly compared and subjected to data restoration, the problem that the data of a physical library and the data of a cache library are inconsistent is avoided, and therefore the processing performance of the application server is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a data processing method, device, and storage medium. Background technique [0002] With the rapid development of the Internet, the scale of users and data are getting larger and larger, and higher requirements are placed on the performance of application servers, and cache is a very critical component. In order to ensure the efficiency of data access, distributed cache is used to provide application servers with high-performance fast data access capabilities. [0003] In order to ensure data accuracy, the application server usually adopts the scheme of double-writing data in the physical library and the cache library. However, during the use of the application server, the consistency of the database and cache data cannot be guaranteed due to physical factors (power failure in the computer room, etc.), application anomalies (memory error reporting af...

Problems solved by technology

However, during the use of the application server, the consistency of the database and cache data cannot be guaranteed due to physical factors (power failure in the computer room, etc.), application anomalies (memory error reporting after physical storage, etc.), or network flash off (memory data loss), etc. , leading to a decrease in the processing performance of the application server
