Abstract

The invention discloses a data processing method, device and apparatus and a medium, is applied to the technical field of databases, and is used for solving the problem that corresponding data in a database is lost and cannot be recovered due to misoperation when a user initiates a data deletion request. The method specifically comprises the following steps: generating a deletion operation messagerecording user request time and a data deletion condition of a data deletion request, and adding the deletion operation message into a deletion operation message queue, so that the deletion operationmessage can be obtained from the deletion operation message queue when timing time is up; after determining that the time difference between the user request time of the deletion operation message record and the current time exceeds the time threshold value, executing physical deletion on the data meeting the data deletion condition of the deletion operation message record in the database, and therefore even if misoperation occurs when a user initiates the data deletion request, the user can delete the data conveniently. Corresponding data can be obtained from the database and recovered within a certain time range, and therefore the data recovery function is achieved.

Description

technical field [0001] The present application relates to the technical field of databases, and in particular to a data processing method, device, equipment and medium. Background technique [0002] Database (Database) is a warehouse for data storage and data management according to the data structure. There are many types of databases, from the simplest tables storing various data to large database systems capable of storing massive data. widely used. [0003] In practical applications, data deletion in the database is a relatively common data management method. Users can initiate a data deletion request through the client, and the server performs a physical deletion operation on the corresponding data in the database according to the data deletion request initiated by the user. That is to say , the database responds immediately to the data deletion request initiated by the user. Therefore, once the user makes a wrong operation when the client initiates the data deletion r...
