Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims, and it should be understood that the specific embodiments described herein are merely illustrative and explanatory of the disclosure and are not restrictive of the disclosure.
It should be noted that all actions of acquiring signals, information or data in the present application are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
First, an application scenario of the present disclosure is explained, with the development of internet technology, the iteration speed of a software version is increased, and as software compatibility problems caused by iterative update of the software version are increasingly prominent, the inventor finds that different users have different preferences for the software version, for example, in e-commerce applet software, an operator may issue a new applet template, for example, new functions such as support for killing seconds, group purchase, and the like. After the software version is switched, the data interface corresponding to the target version of the target program may be changed, for example, because new functions such as killing by seconds, group purchase and the like are added, a killing by seconds price field is added to the data interface of the order data. Under the condition that a data interface of a target program is changed, if program data corresponding to a current version cannot be timely migrated to a database corresponding to the target version, the program data of the current version may be lost or inconvenient to access, and user experience may be affected.
Therefore, the present disclosure provides a data migration method, apparatus, electronic device and storage medium. Under the condition that the interface of the data interface of the target program is changed, program data of the current version can be migrated to the database corresponding to the target version, the integrity of the program data of the target program is guaranteed, and the user experience is improved.
The present disclosure is described below with reference to specific examples.
FIG. 1 is a flow chart illustrating a method of data migration, which may include the steps, as shown in FIG. 1, of:
in step S101, the audit status of the target version of the target program is acquired.
The target version may be an updated version of the current version of the target program, and the audit status may include passed, failed, and in-audit.
In the internet application, the target version release of the target program generally needs to be checked by a platform party, which may be an application store platform party, or a basic service platform party, such as a chat applet platform, a payment applet platform, and the like, which is not limited by the present disclosure. Fig. 2 is a logic diagram of a party associated with a target program according to an exemplary embodiment, and as shown in fig. 2, an application party is a decider of a service version of the target program, and may submit the target version of the target program to a platform side for review according to own software requirements, and after the target version of the target program passes the platform side for review, may provide a service to an end user using the target version of the target program. The target version of the target program may be provided by an operator, or may be obtained and generated from other channels, which is not limited by the present disclosure. For example, in the e-commerce application, an application party serving as an e-commerce merchant may apply an applet template provided by an operator to generate a target version of the target program to be submitted to a platform party for auditing, or may apply a third-party applet template or secondary development to generate a target version of the target program to be submitted to a platform party for auditing.
In step S102, when the audit state of the target version is passed, the interface change state of the data interface of the target program is acquired.
In some possible implementation manners, the data interface change state of the target program may be obtained through a preset version description (Release notes) of the target version.
For example, in the e-commerce application, a killing-by-second module is added in the target version, and when the audit state of the target version submitted by a certain merchant as an application party is passed, and the terminal user opens the interface of the merchant, the interface of the target version is displayed, that is, a newly added killing-by-second function can be provided, and accordingly, a killing-by-second price field can be added in the data interface of the target program in the order data table to record the price information of the order in a killing-by-second mode. The data interface change state of the target program can be obtained through the preset version description of the target version.
In step S103, when the interface change state indicates that the data interface of the target program is changed from the first interface to the second interface, the program data corresponding to the current version is migrated from the database corresponding to the current version to the database corresponding to the target version.
The first interface is a data interface between the target program and the database corresponding to the current version, and the second interface is a data interface between the target program and the database corresponding to the target version.
Therefore, by the scheme, under the condition that the interface change state of the data interface of the target program is changed, the program data of the current version can be migrated to the database corresponding to the target version, the integrity of the program data of the target program is guaranteed, and the user experience is improved.
Fig. 3 is a flowchart of a step S103 shown in the embodiment of fig. 1, and as shown in fig. 3, in one embodiment, the step of S103 may include the following steps:
in step S1031, the data migration state of the program data corresponding to the current version is acquired.
And the data migration state represents whether the program data is migrated from the database corresponding to the current version to the database corresponding to the target version.
In a possible implementation manner, the data migration state of the program data corresponding to the current version may be obtained through a preset data migration state.
For example, in the e-commerce application, after submitting the target version of the target program to the audit, the e-commerce merchant serving as the application party changes the preset data migration state corresponding to the e-commerce merchant into non-migration state, which indicates that the e-commerce merchant submits the target version of the target program to the platform party for the audit, and program data of the target program is not migrated.
In step S1032, when the data migration status is not migrated, the program data is migrated from the database corresponding to the current version to the database corresponding to the target version through the asynchronous data migration process.
The asynchronous data migration represents that the normal use of the target program is not influenced in the data migration process.
Illustratively, in the e-commerce application, in the case that the audit state of the target version is passed, the presentation interface of the newly accessed end user is the interface of the target version. The accessed terminal user receives the prompt of the version change and responds to the operation of the user to switch the display interface of the accessed terminal user to the target version. And the program data generated by the terminal user through the interface of the target version is stored in the database corresponding to the target version through the second interface of the target version.
In some possible implementations, the program data may be migrated from the database corresponding to the current version to the database corresponding to the target version through an asynchronous data migration process as follows.
The method comprises the steps of firstly, obtaining a preset data mapping relation of a first interface and a second interface of a target program.
In some possible implementations, the preset data mapping relationship may be obtained from version descriptions (Release nodes) of the target version.
The preset data mapping relationship may reflect a field mapping relationship of the first interface and the second interface.
For example, in an e-commerce application, a second killing module is added to a target version of the target program, a second killing price is added to an order management table, and the data mapping relationship may include the field mapping relationship described in table 1.
| First interface | Order number | Name of commodity | Price of goods | Number of | Price of bargain | Total price of transaction | Payment mode | |
| Second interface | Order number | Name of commodity | Price of goods | Second killing price | Number of | Price of bargain | Total price of transaction | Payment mode |
TABLE 1
As shown in table 1, the killing-by-second price in the second interface is a newly added field, and the rest are all in a one-to-one correspondence relationship.
Further, the preset data mapping relationship may also reflect a corresponding relationship of value spaces in corresponding fields of the first interface and the second interface.
For example, in an e-commerce application, the value space of some fields of the second interface is changed compared with that of the first interface, and the data mapping relationship may include the value space mapping relationship described in table 2.
| Field(s) | First interface | Second interface |
| Payment mode | 0-Payment mode 1, 1-Payment mode 2, 2-Payment mode 3 | 100-Payment mode 1, 101-Payment mode 2,102-payment mode 3, 103-payment mode 4 |
TABLE 2
As shown in table 2, the value spaces of the payment method fields corresponding to the first interface and the second interface are changed, and the value space in the first interface is [0,1,2 ]. The second interface is [100,101,102,103], and a payment mode is added to the second interface.
It should be noted that table 1 and table 2 only give examples of data mapping relationships, and the disclosure does not limit this.
And secondly, migrating the program data from the database corresponding to the current version to the database corresponding to the target version through the asynchronous data migration process according to the preset data mapping relation.
After the preset data mapping relationship is obtained, the asynchronous data migration process may migrate the program data from the database corresponding to the current version to the database corresponding to the target version according to the preset data mapping relationship.
In some possible implementation manners, the asynchronous data migration process may be implemented by a hyper (high performance PHP micro service framework) and a Swoole (PHP asynchronous network communication engine), and a plurality of asynchronous data migration processes may be implemented by Rabbitmq (message-oriented middleware), which may be specifically described in related art and is not described herein again.
Fig. 4 is a flowchart of another step S103 shown in the embodiment shown in fig. 1, and as shown in fig. 4, in one implementation, the step S103 may further include the following steps:
in step S1033, after the program data is migrated from the database corresponding to the current version to the database corresponding to the target version by the asynchronous data migration process, the data migration status of the program data corresponding to the current version is changed to migrated.
For example, in an e-commerce application, after program data is migrated from a database corresponding to a current version to a database corresponding to a target version through an asynchronous data migration process, a preset data migration state corresponding to the e-commerce merchant is changed to migrated. The method avoids repeated data or data collision caused by the asynchronous data migration process repeatedly migrating the program data from the database corresponding to the current version to the database corresponding to the target version.
By the scheme, under the condition that the interface change state of the data interface of the target program is changed, the program data of the current version can be migrated to the database corresponding to the target version, so that the integrity of the program data of the target program is guaranteed, and the user experience is improved.
FIG. 5 is a flow chart illustrating a method of data migration, according to an example embodiment, which may further include the steps of, as shown in FIG. 5:
in step S104, the service version is determined according to the audit state of the target version of the target program.
For example, in an e-commerce application, a merchant is a decider of a service version of a target program, and can determine the service version of the target program based on software requirements, the number of categories is large, merchants with intense promotion are interested in adopting the target version to meet the needs of commercial marketing, and the categories are small, and merchants with little product requirement change consider that the current version meets the needs and do not like frequently updating the target version. The application side can submit the target version of the target program to the platform side for examination according to the software requirement of the application side. For merchants who do not wish to use the target version, the target version of the target program may not be submitted for review, so that the current version continues to be used as the service version.
In some possible implementations, the service version may be determined from the audit status of the target version of the target program in the following manner.
In the method 1, when the audit state of the target version of the target program is in the audit or fails, the current version of the target program is used as the service version.
For example, in the e-commerce application, in the case that the target version of the target program submitted by the merchant has not passed the audit or the result of the audit is failed, the current version of the target program is taken as the service version.
And in the mode 2, when the auditing state of the target version of the target program is passed, the target version of the target program is used as the service version.
For example, in the e-commerce application, in the case that the audit state of the target version of the target program submitted by the merchant is passed, the target version of the target program is taken as the service version.
In step S105, an interface of the service version is presented to the user, so as to provide the service for the user with the service version.
The user may be an end user shown in fig. 2, for example, a consumer in an e-commerce application, and submit an order through an interface of the service version to complete shopping, an application party shown in fig. 2, for example, a merchant in the e-commerce application, and complete daily operations through an interface of the service version, or an operator shown in fig. 2, for example, an e-commerce platform in the e-commerce application, and complete management of multiple merchants through an interface of the service version, or issue a target version template (for example, an applet template) of a new target program, for the application party to download the target version template to generate a target version.
By the scheme, the service version can be determined according to the auditing state of the target version of the target program, the version requirements of different users are met, the compatibility of the target program is improved, and the user experience is improved.
FIG. 6 is a flow chart illustrating yet another method of data migration, as shown in FIG. 6, which may include the steps of:
in step S601, the audit state of the target version of the target program is acquired.
The target version may be an updated version of the current version of the target program, and the audit status may be passed, failed, and in the audit.
In step S602, the interface change state of the data interface of the target program is acquired.
And acquiring the interface change state of the data interface of the target program under the condition that the audit state of the target version is passed.
In some possible implementations, the data interface change status of the target program may be obtained through a preset version specification (Release notes) of the target version. For a specific description, refer to the description of step S102, which is not repeated herein.
In step S603, the data migration status of the program data corresponding to the current version is acquired.
And the data migration state represents whether the program data is migrated from the database corresponding to the current version to the database corresponding to the target version.
And under the condition that the interface change state represents that the data interface of the target program is changed from the first interface to the second interface, acquiring the data migration state of the program data corresponding to the current version through a preset data migration state.
For example, in the e-commerce application, after submitting the target version of the target program to the audit, the e-commerce merchant serving as the application party changes the preset data migration state corresponding to the e-commerce merchant into non-migration state, which indicates that the e-commerce merchant submits the target version of the target program to the platform party for the audit, and program data of the target program is not migrated.
In step S604, a preset data mapping relationship between the first interface and the second interface of the target program is obtained.
The preset data mapping relation may reflect a field mapping relation between the first interface and the second interface. In some possible implementations, the preset data mapping relationship may be obtained from version descriptions (Release nodes) of the target version.
And under the condition that the data migration state is not migrated, acquiring a preset data mapping relation between a first interface and a second interface of the target program. The preset data mapping relationship may reflect a field mapping relationship of the first interface and the second interface. Further, the preset data mapping relationship may also reflect a corresponding relationship of value spaces in corresponding fields of the first interface and the second interface, which is not limited by the present disclosure.
In step S605, the program data is migrated from the database corresponding to the current version to the database corresponding to the target version according to the preset data mapping relationship through the asynchronous data migration process.
After the preset data mapping relationship is obtained, the asynchronous data migration process may migrate the program data from the database corresponding to the current version to the database corresponding to the target version according to the preset data mapping relationship.
In step S606, the data migration status of the program data corresponding to the current version is changed to migrated.
For example, in an e-commerce application, after program data is migrated from a database corresponding to a current version to a database corresponding to a target version through an asynchronous data migration process, a preset data migration state corresponding to the e-commerce merchant is changed to migrated. The method avoids repeated data or data collision caused by the asynchronous data migration process repeatedly migrating the program data from the database corresponding to the current version to the database corresponding to the target version.
In step S607, the target version of the target program is set as the service version.
And when the auditing state of the target version is passed, taking the target version of the target program as a service version.
In step S608, the current version of the target program is taken as the service version.
