Embodiment 1

[0026] This embodiment provides a function analysis method, refer to figure 1 , the method may include the following steps:

[0027] Step S102, after the program is started, obtain functions and check the blacklist; wherein, the functions include system functions and user-defined functions; the blacklist is used to record functions written into the database among the functions.

[0028] In some possible implementation manners, the above-mentioned program may be a driver program added in the host server, or may be a designed proxy (Proxy) program or the like. Functions can include system functions that come with the database system when it is initialized, and user-defined functions pre-created by users to meet actual needs; at the same time, according to the operation type of the function is a read operation or a write operation, the function can be divided into write to the database function (namely write function) and read database function (namely read function); wherein, w...

Embodiment 2

[0059] refer to figure 2 , the present embodiment provides a function analysis device, the device includes:

[0060] The checking module 202 is used to check the blacklist after the program starts; wherein, the blacklist is used to record and write the database function;

[0061] The first determination module 204 is used to determine the first write-in database function from a pre-established database table if the write-in database function recorded in the blacklist is empty; wherein, the database table is used to store system functions of the database system;

[0062] The second determination module 206 is used to execute the user-defined function based on the blacklist, and determine the second write-in database function in the user-defined function according to the execution result if there is a function written into the database recorded in the blacklist;

[0063] Adding to a blacklist module 208, configured to add the first writing function to the database and the seco...

Abstract

The invention provides a function analysis method and device and electronic equipment, and relates to the technical field of databases, and the method comprises the steps: obtaining a function and checking a blacklist after a program is started, wherein the functions comprise a user-defined function and a system function of the database system, the blacklist is used for recording a write-in database function in the function; if the write-in database function recorded in the blacklist is empty, determining a first write-in database function from the system functions according to the read-writeattribute; if the write-in database function is recorded in the blacklist, executing the user-defined function based on the blacklist, and determining a second write-in database function in the user-defined function according to an execution result; and adding the first write-in database function and the second write-in database function into the blacklist. The working difficulty of configuring the black list and the white list can be obviously simplified.

Description

technical field [0001] The present disclosure relates to the technical field of databases, in particular to a function analysis method, device and electronic equipment. Background technique [0002] Read-write separation means that the host server handles transactional addition, modification, and deletion operations, while the standby server handles SELECT query operations. [0003] In the process of processing functions, the existing read-write separation scheme usually requires the user to configure the black and white list of functions separately to identify the read-write type of the function, and then achieve the read database function (called read function) distributed to the standby server, write The database entry function (which may be called a write function) is sent to the host server to improve the overall processing capacity of the cluster. Such a scheme of separately configuring the black and white lists of functions is very cumbersome for users, especially wh...
