Rather, embodiments of the 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 flow diagram of a method of 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.
In the present application, the device for obtaining the key value parameter corresponding to at least one key value in the Redis system is not specifically limited, and may be, for example, an intelligent device or a server. The smart device may be a PC (Personal Computer ), or may be a smart phone, tablet computer, e-book reader, MP3 (Moving Picture Experts Group AudioLayer III, dynamic image expert compression standard audio layer 3) data prefix adder. MP4 (Moving Picture ExpertsGroup Audio Layer IV, MPEG audio layer 4) data prefix adding device, portable computer and other mobile terminal equipment with display function.
Further, the Redis is an open-source non-relational database written in ANSI language, supporting network, memory-based, supporting persistent log-type, key-Value storage (Key-Value), and the corresponding Value (Value) stored in the Redis database can be obtained through Key name or Key master (Key). The traditional relational databases such as Oracle, mySQL and SQLServer are used for classifying complex data structures into binary relations, namely, two-dimensional table forms, and the operation on the data is built in one or more relational tables and realizes data processing through operations such as classification, merging, connection, selection and the like among tables.
In the context of online education of the internet, some data that is frequently displayed and/or not frequently changed need to be stored in a memory (or a storage service) that is a cache with a faster access speed, and Redis is often used for storing the data due to the advantages of Redis in terms of key factors such as resource convenience performance optimization. For example, in storing video data of a lecture, when a user obtains video of the lecture according to the user name (Identity) of both parties participating in the lecture, the curriculum information and the user information can be cached in Redis. For viewing by the user.
In the application, the key value parameter corresponding to at least one key value in the Redis system can be obtained, wherein the key value parameter is used for representing whether the corresponding key value has prefix information or not. It will be appreciated that there are a large number of Key values keys in the Redis system. There will be a key containing prefix information and there will also be a key not containing prefix information. In the application, the key value parameter corresponding to each key value in the Redis system can be traversed at first, so that the corresponding key value is selected according to the key value parameter later.
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 a key value which does not contain prefix information in at least one key value.
The method aims to solve the problem that in the related art, the efficiency of searching the target key value is low when the target key value faces to a large number of key values. The application can acquire the target key value which does not contain prefix information in at least one key value based on the key value parameter corresponding to the at least one key value.
It should be noted that, the method of selecting the target key value is not specifically limited in the present application, for example, the key value containing prefix information may be screened out from at least one key value, so as to obtain the target key value. Or selecting a key value which does not contain prefix information from at least one key value, thereby obtaining the target key value.
S103, adding corresponding prefix information for 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 configuration file generated in advance. And adds each prefix information correspondence to the target key value. To ensure that each target key value is assigned corresponding prefix information.
In the application, after the key value parameters which are corresponding to the key values and are used for representing the prefix information in the Redis system are obtained, the target key value which does not contain the prefix information in the key values can be selected based on the key value parameters corresponding to the key values, and the corresponding prefix information is added for the target key value based on the configuration file corresponding to the target key value. By applying the technical scheme of the application, when the key value without prefix information is detected to be contained in the Redis system, the prefix information stored in the configuration file can be added to the corresponding key value. And the problem of low efficiency of searching the target key value when facing to massive key values in the related technology can be avoided.
Alternatively, in one possible implementation manner of the present application, in S103 of the present application (prefix information is added to the target key value based on the configuration file corresponding to the target key value), the method may be generated as follows:
acquiring a configuration file corresponding to the target key value;
detecting whether the configuration file contains first prefix information of a target key value or not;
if included, the first prefix information is added to 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 configuration file generated in advance. And adding each prefix information to the target key value correspondingly to ensure that each target key value is distributed with the corresponding prefix information.
Furthermore, the present application may first obtain a configuration file corresponding to the target key value, and find whether the configuration file contains the first prefix information of the target key value. It can be appreciated that when the first prefix information including the target key value in the configuration file is detected, the first prefix information can be added to the corresponding target key value.
Further optionally, when the configuration file does not contain the prefix information of the target key value, a restart instruction is generated, where the restart instruction is used to prompt the user to add the prefix information corresponding to the target key value in the configuration file.
When the first prefix information of the target key value is not contained in the configuration file, in order to ensure that each target key value is configured with the prefix information, the application can generate a restarting instruction for prompting a user to add the prefix information corresponding to the target key value in the configuration file. It can be understood that the method and the device can be used for displaying for the user in a preset mode after the restart instruction is generated. For example, the reminding mode is that a reminding icon is displayed in a voice broadcasting mode.
In a possible embodiment of the present application, after the step S102 of the present application (selecting the target key value based on the key value parameter corresponding to at least one key value), the present application further proposes a method for adding a data prefix, as shown in fig. 2, where 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, obtaining 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 which does not contain prefix information is obtained, the method and the device can simultaneously correspond to a plurality of service businesses due to the fact that a certain key value possibly exists. That is, when the user queries the key, a situation may occur that a false deletion occurs due to the unaware of the service in which the key is located. 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 determining that they are completed, the disadvantage that the service C cannot operate may occur.
Therefore, in order to avoid the problem of influencing the service efficiency caused by the existence of the target key value and the simultaneous correspondence of a plurality of services, the service identifier corresponding to the target key value can be acquired first. It can be understood that the service identifier is used for representing the service served by the target key value. For example, there may be storage traffic, analysis traffic, processing traffic, and the like.
In addition, the number of service identifiers is not specifically limited in the present application, and may be, for example, 1 or more.
In addition, the method for acquiring the service identifier is not particularly limited in the same way, for example, the service identifier can be set in a key value parameter of a target key value, and the service identifier can also be obtained by a user after inquiring information stored in a server.
S204, based on the service identification, whether the configuration file contains second prefix information of the target key value is detected.
Optionally, in the process of detecting whether the configuration file contains the second prefix information of the target key value based on the service identifier, the method can be obtained through the following steps:
detecting the number of service identifiers corresponding to the target key value;
when the number of the service identifiers exceeds the preset number, detecting whether the configuration file contains second prefix information of the target key value or not;
if so, detecting the number of the second prefix information.
Furthermore, the application can further detect the number of the service identifiers after the service identifiers corresponding to the target key values are obtained. And detecting whether the configuration file contains second prefix information with the number or not when the number of the service identifiers exceeds the preset number.
It should be noted that the preset number is not specifically limited in the present application, and may be, for example, 2, 5, or the like.
It can be understood that the reason why the present application further obtains the amount of the second prefix information is to avoid the problem that the service efficiency is affected due to the fact that the target key value corresponds to a plurality of services at the same time. In other words, when it is detected that a target key value exists while corresponding to a plurality of services, a plurality of prefix information needs to be added to the target key value later so that the user can know all the traffic of the key value service. This also avoids that when the user uses redis, different services use keys without prefixes, resulting in at least one service being intermixed, which is inconvenient to manage and govern key values.
S205, when the number of second prefix information is detected to be lower than the preset number, generating the preset number of second prefix information based on the service identifiers, where each second prefix information corresponds to each service identifier.
Further, in the present application, when the number of the second prefix information is detected to be lower than the preset number, the preset number of the second prefix information can be generated for the target key value. It should be noted that, each second prefix information corresponds to each service identifier.
Furthermore, the method for generating the second prefix information is not particularly limited, and for example, a plurality of corresponding second prefix information can be generated according to the service type and the random code technology corresponding to each service identifier. Alternatively, a plurality of corresponding second prefix information may be generated according to the service name and the random code technique corresponding to each service identifier. It should be noted that, the mode of generating the preset amount of the second prefix information is changed, so that the protection scope of the present application is not affected.
S206, adding the second prefix information with the preset quantity to the corresponding target key value.
Furthermore, after generating the second prefix information with the preset quantity based on the service identifier, the application can respectively and correspondingly add the second prefix information into the target key value of the sub-category. So that the user can know the business information of the key value service according to a plurality of pieces of second prefix information contained in the target key value when inquiring or managing the target key value later.
S207, when a query instruction for the target key value is received, the target key value is acquired based on prefix information corresponding to the target key value.
Further, after adding the second prefix information with preset quantity to the corresponding target key value, when receiving the query instruction aiming at the target key value, the application can acquire the corresponding target key value according to the prefix information of the target key value. To help the developer to increase efficiency in subsequent queries or management of target key values.
In the application, after the key value parameter which corresponds to at least one key value in the Redis system and is used for representing the prefix information is 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 parameter which corresponds to the at least one key value, and the corresponding prefix information is added for the target key value based on the configuration file which corresponds to the target key value. By applying the technical scheme of the application, when the key value without prefix information is detected to be contained in the Redis system, the prefix information stored in the configuration file can be added to the corresponding key value. And the problem of low efficiency of searching the target key value when facing to massive key values in the related technology can be avoided.

In the application, after the key value parameters which are corresponding to the key values and are used for representing the prefix information in the Redis system are obtained, the target key value which does not contain the prefix information in the key values can be selected based on the key value parameters corresponding to the key values, and the corresponding prefix information is added for the target key value based on the configuration file corresponding to the target key value. By applying the technical scheme of the application, when the key value without prefix information is detected to be contained in the Redis system, the prefix information stored in the configuration file can be added to the corresponding key value. And the problem of low efficiency of searching the target key value when facing to massive key values in the related technology can be avoided.
