A method for data prefix addition according to an exemplary embodiment of the present application is described below in conjunction with fig. 1-2. It should be noted that the following application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.
The application also provides a method, a device, a target terminal and a medium for adding the data prefix.
Fig. 1 schematically shows a flowchart of a method for data prefix addition according to an embodiment of the present application. As shown in fig. 1, the method includes:
s101, obtaining a key value parameter corresponding to at least one key value in the Redis system, wherein the key value parameter is used for representing prefix information corresponding to the key value.
It should be noted that, in the present application, a device for acquiring a key value parameter corresponding to at least one key value in a Redis system is not specifically limited, and may be, for example, an intelligent device or a server. The intelligent device may be a PC (Personal Computer), a smart phone, a tablet Computer, an e-book reader, and an MP3(Moving Picture Experts Group audio layer III) data prefix adder. MP4(Moving Picture expert group Audio Layer IV), a device for adding data prefix, a portable terminal device such as a portable computer with a display function, and the like.
Furthermore, Redis is an open-source non-relational database which is written by ANSI, supports network, is based on memory, supports persistent log type and Key-Value storage (Key-Value), and can acquire a corresponding Value (Value) stored in the Redis database through a Key name or a primary Key (Key). In the traditional relational databases such as Oracle, MySQL, SQLServer and the like, complex data structures are classified into a binary relation, namely a two-dimensional table form, data operation is established in one or more relational tables, and data processing is realized through operations such as classification, combination, connection, selection and the like among the tables.
In the internet online education scenario, some data that is frequently displayed and/or is not frequently changed needs to be stored in a cache (or storage service) with a faster access speed, and the Redis is often used to store the data due to its advantages in terms of obtaining resources, facilitating performance optimization, and other key factors. For example, when the user can obtain the video for teaching based on the user name (Identity, ID) of both parties participating in the teaching in the video data for teaching, the course information and the user information can be cached in Redis. For viewing by the user.
In the application, key value parameters corresponding to at least one individual key value in the Redis system can be obtained, wherein the key value parameters are used for representing whether the corresponding key value has prefix information. It can be understood that there are a large number of Key values Key in the Redis system. There may be a key value containing prefix information, and there may also be a key value not containing prefix information. In the application, the key value parameter corresponding to each key value in the Redis system can be traversed first, so that the corresponding key value is selected subsequently according to the key value parameter.
And S102, selecting a target key value based on a key value parameter corresponding to at least one key value, wherein the target key value is the key value which does not contain prefix information in the at least one key value.
The method and the device aim to solve the problem that efficiency of searching for the target key values is low when a large number of key values are faced in the related technology. According to the method and the device, the target key value which does not contain prefix information in at least one key value can be obtained based on the key value parameter corresponding to the at least one key value.
It should be noted that the method for selecting the target key value is not specifically limited in the present application, and for example, the method may be to screen out the key values including the prefix information from at least one key value, so as to obtain the target key value. Or selecting a key value without prefix information from at least one key value to further obtain the target key value.
And S103, adding corresponding prefix information to the target key value based on the configuration file corresponding to the target key value.
Further, in the present application, in order to add corresponding prefix information to each target key value, a plurality of prefix information may be extracted from a pre-generated configuration file. And correspondingly adding each prefix information into the target key value. So as to ensure that each target key value is distributed with corresponding prefix information.
In the application, after key value parameters used for representing prefix information and corresponding to each key value in the Redis system are obtained, a target key value which does not contain prefix information in each key value can be selected based on the key value parameters corresponding to each key value, and corresponding prefix information is added to the target key value based on a configuration file corresponding to the target key value. By applying the technical scheme of the application, when the fact that the Redis system contains the key value without the prefix information is detected, the prefix information stored in the configuration file of the Redis system can be added to the corresponding key value. And further, the problem of low efficiency of searching for the target key value when a large number of key values are faced in the related technology can be solved.
Optionally, in a possible implementation manner of the present application, in S103 (based on a configuration file corresponding to the target key value, prefix information is added to the target key value), the generation may be performed in the following manner:
acquiring a configuration file corresponding to a target key value;
detecting whether a configuration file contains first prefix information of a target key value;
and if so, adding the first prefix information into the corresponding target key value.
Further, in the present application, in order to add corresponding prefix information to each target key value, a plurality of prefix information may be extracted from a pre-generated configuration file. And correspondingly adding each prefix information into the target key value to ensure that each target key value is distributed with the corresponding prefix information.
Further, the method and the device for determining the first prefix information of the target key value can firstly obtain a configuration file corresponding to the target key value, and find out whether the first prefix information of the target key value is included in the configuration file. It can be understood that when the first prefix information including the target key value in the configuration file is detected, the first prefix information may be added to the corresponding target key value.
Further optionally, when it is detected that the configuration file does not contain prefix information of the target key value, a restart instruction is generated, where the restart instruction is used to prompt a user to add prefix information corresponding to the target key value in the configuration file.
When it is detected that the configuration file does not contain the first prefix information of the target key value, in order to ensure that each target key value is configured with the prefix information, a restart instruction for prompting a user to add the prefix information corresponding to the target key value in the configuration file may be generated. It can be understood that the restart instruction can be displayed for the user in a preset mode after being generated. For example, the reminding is broadcasted by voice, and reminding icons are displayed.
In a possible embodiment of the present application, after the application S102 (selecting a target key value based on a key value parameter corresponding to at least one key value), the application further provides a method for adding a data prefix, as shown in fig. 2, the method includes:
s201, obtaining a key value parameter corresponding to at least one key value in the Redis system.
S202, selecting a target key value based on the key value parameter corresponding to at least one key value.
S203, acquiring a service identifier corresponding to the target key value, wherein the service identifier is used for representing the service served by the target key value.
Further, after the target key value not containing the prefix information is obtained, a certain key value may exist in a plurality of service services simultaneously. That is, when the user queries the key value, the user may miss the key value due to the unknown service. For example, when the target key value X corresponds to the service a, the service B, and the service C at the same time, and the user does not know the service where the key value X is located, if the user deletes the service a and the service B where the key value X is located after the determination is completed, the service C may not be operated.
Therefore, in order to avoid the problem that the business efficiency is affected because the target key value simultaneously corresponds to a plurality of services, the business identifier corresponding to the target key value can be obtained first in the application. As can be understood, the service identifier is a service served for characterizing the target key. For example there may be storage services, analysis services, processing services, etc.
In addition, the number of the service identifiers is not specifically limited in the present application, and may be, for example, 1 or more.
In addition, the method for obtaining the service identifier is not specifically limited in the same manner, for example, the service identifier may be set in a key value parameter of the target key value, and the service identifier may also be obtained by a user by querying information stored in the server.
S204, based on the service identifier, detecting whether the configuration file contains second prefix information of the target key value.
Optionally, in the process of detecting whether the configuration file includes the second prefix information of the target key value based on the service identifier in the present application, the following steps may be performed:
detecting the number of the business identifications corresponding to the target key values;
when the number of the service identifications is detected to exceed the preset number, whether the configuration file contains second prefix information of the target key value is detected;
and if so, detecting the quantity of the second prefix information.
Further, after the service identifier corresponding to the target key value is obtained, the number of the service identifiers can be further detected. And when determining that the number of the service identifiers exceeds the preset number, detecting whether the configuration file contains the second prefix information with the number.
It should be noted that the preset number is not specifically limited in the present application, and for example, the number may be 2, or 5.
It can be understood that the reason for further acquiring the number of the second prefix information is to avoid the problem that the service efficiency is affected because the target key value corresponds to multiple services at the same time. In other words, when it is detected that the target key value corresponds to multiple services at the same time, multiple pieces of prefix information need to be added to the target key value in the following, so that the user can know all services of the key value service. This also avoids that when the user uses redis, different services use keys without prefixes, causing at least one service to be mixed together, which is inconvenient for managing and governing the key values.
S205, when it is detected that the number of the second prefix information is lower than the preset number, generating a preset number of second prefix information based on the service identifier, where each second prefix information corresponds to each service identifier.
Further, in the present application, when it is detected that the number of the second prefix information is lower than the preset number, the preset number of second prefix information may be generated for the target key value. It should be noted that, each second prefix information corresponds to each service identifier.
Further, the method for generating the second prefix information is not specifically limited in the present application, and for example, a plurality of corresponding second prefix information may be generated according to the service type corresponding to each service identifier and the random code technology. Alternatively, a plurality of corresponding second prefix information and the like may be generated according to the service name and the random code technique corresponding to each service identifier. It should be noted that the variation of the manner of generating the preset number of second prefix information does not affect the protection scope of the present application.
And S206, adding a preset number of second prefix information into the corresponding target key value.
Further, after a preset number of second prefix information is generated based on the service identifier, the multiple second prefix information may be respectively and correspondingly added to the affiliated target key values. Therefore, when a user inquires or manages the target key value subsequently, the user can know the service information of the key value service according to the plurality of second prefix information contained in the target key value.
And S207, when a query instruction aiming at the target key value is received, acquiring the target key value based on prefix information corresponding to the target key value.
Further, after a preset amount of second prefix information is added to the corresponding target key value, when a query instruction for the target key value is received, the corresponding target key value can be obtained according to the prefix information of the target key value. The method helps the developer to improve efficiency when the developer inquires or manages the target key value subsequently.
In the application, after key value parameters corresponding to at least one key value and used for representing prefix information in the Redis system are obtained, a target key value which does not contain the prefix information in the at least one key value can be selected based on the key value parameters corresponding to the at least one key value, and corresponding prefix information is added to the target key value based on a configuration file corresponding to the target key value. By applying the technical scheme of the application, when the fact that the Redis system contains the key value without the prefix information is detected, the prefix information stored in the configuration file of the Redis system can be added to the corresponding key value. And further, the problem of low efficiency of searching for the target key value when a large number of key values are faced in the related technology can be solved.
