Problems solved by technology

However, in most kv databases, there is no functional interface to obtain the amount of data, so the application needs to implement the logic of statistical counting
[0003] In the existing technology, the following three methods are usually used to realize the counting of data: the first method uses heterogeneous databases to store the counts, and in this method, the information of the two databases will not be unified, resulting in counting errors; the second method uses key value to store the counting information. In this way, the data can only be processed serially, which affects the efficiency of data processing. The third method does not store the counting information. When it is necessary to obtain the amount of database data, the database is scanned in its entirety. It takes a lot of time to query

Embodiment 1

[0033] figure 1 It is a flow chart of a method for counting database data provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of counting the amount of data in the database. The method can be executed by a counting device for database data. The device It can be composed of hardware and / or software, and generally can be integrated into a device with data access function, which can be an electronic device such as a server or a server cluster. like figure 1 As shown, the method specifically includes the following steps:

[0034] Step 110, generating count variation data according to the data volume of the data to be processed.

[0035] Wherein, the data to be processed may include data to be written and data to be deleted. The amount of data can be reflected by the number of data items. The counting variation data carries a setting identification code, and the setting identification code may be a setting prefix. The form of counting v...

Abstract

The embodiment of the invention discloses a database data counting method, device and apparatus and a storage medium. The method comprises: generating counting variation data according to the data volume of to-be-processed data, writing the counting variation data into a database, and updating the count value of the database according to the count variation data. According to the counting method of the database data disclosed by the embodiment of the invention, the counting variable quantity data is processed into the database together, so that the counting value of the database is updated according to the counting variable quantity data, the accuracy of data counting can be improved, and the normal service of the database is not influenced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data counting, and in particular, to a database data counting method, device, equipment, and storage medium. Background technique [0002] The amount of data stored in the database is a very common requirement. In a SQL database, if you need to count the amount of data in a table, you can use a statement such as SELECT COUNT(1) FROM table. Execution of this statement returns the table The number of record rows. However, in most kv databases, there is no functional interface for obtaining data volume, so the application program is required to implement the logic of statistical counting. [0003] In the existing technology, the following three methods are usually used to realize the counting of data: the first method uses heterogeneous databases to store the counts, and in this method, the information of the two databases will not be unified, resulting in counting errors; the seco...
