It should be noted that the following application scenario is only shown for the convenience of understanding the spirit and principles of the present application, and embodiments of the present application are not limited in any way in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.
The application provides a method, a device, a target terminal and a medium for synchronizing data.
Fig. 1 schematically shows a flow diagram of a method of synchronizing data according to an embodiment of the present application. As shown in fig. 1, the method includes:
s101, acquiring a synchronous instruction, wherein the synchronous instruction carries first change data, and the change data is data with changed data content in a relational database.
Firstly, it should be noted that the method for acquiring the synchronous instruction is not particularly limited in the present application. For example, the synchronization instruction may be generated by the electronic device after the detection of the reaching of the predetermined condition, or may be received by the electronic device.
In the present application, the change data carried in the synchronization instruction may be data in which the data content is changed in the relational database. Further, a relational database is a database based on a relational model, and the relational database processes data in the database by means of mathematical concepts and methods such as set algebra. In relational databases, data is typically stored in rows and columns to facilitate a user's retrieval of the data in the database with a Query (Query).
Further, the relational database is not particularly limited in this application, and for example, the relational database using this application may be MYSQL, SQLITE, MARIADB or the like.
In the present application, the data type of the change data is not specifically limited, that is, the change data may be consumption data type information, enterprise commodity type data information, or the like. In one possible preferred embodiment, the data type of the change data in the present application may be order-like data information generated by the consumer from the enterprise product. When the type of the change data is order type data information, the change data can be data information generated when the order type data information is changed.
For example, after the user a purchases a corresponding commodity on a website of a certain enterprise by using the electronic terminal, the server generates order type data information a for the action. Further, after a period of time, the user A needs to change the delivery address for personal reasons, and then the user A needs to log in the website of the enterprise again, and after finding the data information A, one item of the delivery address in the data information A is modified. For this behavior, after the user a modifies the data content of the data information a, the relational database generates corresponding modification data concerning the user a.
S102, adding the first change data and a corresponding first position identifier to the change data file, wherein the first position identifier is used for marking the position of the first change data in the change data file.
Optionally, in the present application, after the synchronization instruction carrying the first change data is obtained, the first change data and the corresponding first location identifier may be further added to the change data file. Wherein the first location identifier is used to mark the location of the first change data in the change data file.
S103, synchronizing the added first change data and the change data file of the first position mark to the local disk.
Optionally, in the present application, after the first change data and the corresponding first location identifier are added to the change data file, the change data file to which the first change data and the first location identifier are added may be further synchronized to the local disk.
In the related art, after a user synchronizes to corresponding data from a relational database, the data is typically stored in a memory of an electronic device. So that the business party can extract the data from the memory of the electronic equipment after the business party needs to use the data. It is understood that the present application employs synchronizing the first change data and the change data file of the first location identifier to the local disk. And further, the problem of insufficient synchronous data caused by less memory storage capacity of the electronic equipment can be avoided.
It should be noted that, in the present application, the capacity of the local disk is not specifically limited, that is, the appropriate disk capacity is selected according to the amount of data information of different enterprises. In one possible preferred embodiment, a local disk with a larger capacity may be selected.
Further, the first location identifier in the present application needs to be stored in the change data file in synchronization with the first change data. So as to avoid the disadvantage that the business side consumes the user time caused by repeated searching when more data information exists in the follow-up changed data file.
In the application, after a synchronization instruction is acquired, first change data and a first position identifier are added to a change data file, and then the change data file added with the first change data and the first position identifier is synchronized to a local disk. By applying the technical scheme, the corresponding position identification can be added to the data with changed data content in the relational database, and the changed data and the position identification are synchronized to the local disk. Therefore, the defect that the data cannot be stored for a long time due to the fact that the data are stored in the memory of the electronic equipment in the related art is avoided. Thereby improving user experience.
Further optionally, in an embodiment of the present application, in S101 (acquiring a synchronization instruction), a specific embodiment is further included, as shown in fig. 2, including:
s201, receiving a synchronous instruction sent by a relational database.
Optionally, in the method for obtaining the synchronization instruction, the synchronization instruction carrying the first change data may be generated by the relational database, and after the synchronization instruction is generated by the relational database, the synchronization instruction may be sent to the electronic device.
In this application, the synchronization instruction carrying the first change data may be generated by the relational database, and then sent to the electronic device at the first time. The relational database may not select to send the synchronization instruction carrying the first change data at the first time after generating the synchronization instruction, but may select to send the synchronization instruction after receiving the related request instruction of the electronic device, so that the electronic device receives the synchronization instruction sent by the relational database.
S202, when the first change data exists in the relational database, a first request instruction is sent to the relational database, and the first request instruction is used for acquiring the first change data.
And receiving first change data sent by the relational database, and generating a synchronous instruction based on the first change data.
Optionally, in the method for obtaining the synchronization instruction, the electronic device may send a first request instruction for obtaining the first change data to the relational database after detecting that the first change data is generated in the relational database, and generate the synchronization instruction based on the first change data after receiving the first change data.
In the present application, the time for detecting whether the first change data exists in the relational database is not limited. For example, the electronic device may monitor whether the first change data exists in the relational database in real time, or may detect whether the first change data exists in the relational database after every preset time period. Likewise, the preset time period is not specifically limited in this application. I.e. the preset time period may be 10 minutes, and the preset time period may be 5 minutes.
Further, after receiving the first change data, the present application may generate a synchronization instruction for synchronizing the first change data to the local disk, and store the first change data in the synchronization instruction.
It should be noted that, in the present application, S201 and S202 are implementation steps independent from each other. That is, in one possible embodiment in the present application, the step S203 and subsequent steps may be continued after the step S201 is first performed. Alternatively, after the step of S202 is first performed, the step S203 and subsequent steps may be completed.
S203, adding the first change data and the corresponding first position identification to the change data file.
S204, synchronizing the added first change data and the change data file of the first position mark to the local disk.
S205, when the residual storage space of the local disk is detected to be lower than a preset threshold value, clearing second change data and a corresponding second position mark, wherein the second change data is the change data with the earliest synchronization time in the local disk, and the second position mark is used for marking the position of the second change data in a change data file.
Optionally, in this application, in order to prevent the problem of influencing the operation efficiency caused by overload of the local disk. After the first change data and the change data file of the first position identifier are added to the local disk, the method can further detect the residual storage space of the local disk in the electronic equipment. And after detecting that the residual storage space is lower than a preset threshold value, traversing all the change data in the local disk, and clearing the second change data with earliest synchronization time out of the local disk so as to save the occupied space of the local disk.
It should be noted that, in the present application, the preset threshold is not specifically limited, that is, the preset threshold may be five percent, and the preset threshold may also be three percent. The specific variation of the preset threshold value does not affect the protection scope of the application.
Likewise, when the local disk is cleared from the second change data with the earliest synchronization time, the local disk also needs to be cleared from the second position identifier for marking the position of the second change data in the change data file, and it can be understood that the action can further achieve the purpose of saving the occupied space of the local disk.
In the method, after first change data and a first position identifier are added to a change data file, the change data file added with the first change data and the first position identifier is synchronized to a local disk, and after the fact that the residual storage space of the local disk is lower than a preset threshold value is detected, the earliest change data of the synchronization time is cleared. By applying the technical scheme, the data with changed data content in the relational database and the corresponding position identification can be synchronized to the local disk, and when the fact that the residual storage space of the local disk is insufficient is further detected, the data with earliest synchronization time is cleared. Therefore, the defect that the operation efficiency is affected due to the fact that excessive data are stored in the local disk in the related art is avoided. Thereby improving user experience.
Further optionally, in an embodiment of the present application, after S103 (synchronizing the data file to which the first change data and the first location identifier are added to the local disk), a specific embodiment is further included, as shown in fig. 3, including:
s301, acquiring a synchronous instruction.
S302, adding the first change data and the corresponding first position identification into a change data file.
S303, synchronizing the added first change data and the change data file of the first position mark to the local disk.
S304, when a second request instruction is received, the first change data is called from the change data file based on the second request instruction and the first position identification.
Optionally, in the present application, after synchronizing the change data file added with the first change data and the first location identifier to the local disk, it may be detected whether a second request instruction for retrieving the first change data from the change data file is received, and when the second request instruction is received, the first change data may be retrieved according to the request content of the second request instruction.
In one possible embodiment of the present application, based on the second request instruction and the first location identifier, the specific operation manner of retrieving the first change data from the change data file may be generated by implementing the following steps:
And analyzing the second request instruction, and determining a calling time period and a calling object.
Alternatively, in the present application, the second request instruction for retrieving the first change data from the change data file may be parsed first, where the retrieved time period and the retrieved object carried in the second request instruction are obtained.
Further, since it is possible for the same user to generate a corresponding plurality of change data in different time periods. Therefore, in this application, it is necessary to determine the fetch time period and the fetch object required in the request instruction at the same time.
For example, when the user B purchases a corresponding commodity on the website of a certain enterprise by using the electronic terminal thereof at the time of 8 days 2018.12.12, the server generates order type data information B for the action. Further, after the user a has placed a bill for 3 hours, the user B logs in to the website of the enterprise at 11 on the same day because the user a needs to change the delivery address for personal reasons, and after the data information B is found, one item of the delivery address in the data information B is modified. For this behavior, after the user B modifies the data content of the data information B, the relational database generates change data about the user B at 11 points on 2018.12.12. Furthermore, when the user B needs to modify the contact for personal reasons at 9 days 2018.12.13, the user B logs in the website of the enterprise again at 9 days next, and modifies one of the contact in the data information B after finding the data information B. For this behavior, after the user B modifies the data content of the data information B again, the relational database generates change data about the user B at 9 points on 2018.12.13.
And determining the first change data according to the calling time and the calling object.
Optionally, after the second request instruction is parsed to obtain the calling time period and the calling object, the first change data may be further determined according to the calling time period and the calling object.
Also from the above example, it can be appreciated that when the retrieval time period obtained in the analysis of the second request instruction is 2018.12.12 days and the retrieval target is user b, it is determined that the first change data is change data about the change delivery address generated by user b at 11 th day 2018.12.12. When the calling time period obtained by analyzing the second request instruction is 2018.12.13 days and the calling object is user B, the first changing data is determined to be the changing data about the changing contact way generated by the user B at the point of 2018.12.13 days 9.
And calling the first change data from the change data file based on the first position identification.
Optionally, after determining the first change data, the present application may determine the position of the first change data in the change data file by querying a first position identifier corresponding to the first change data, so as to call the first change data from the change data file.
S305, transmitting first change data.
Optionally, in the present application, after the first change data is called from the change data file, the called first change data may be sent to the corresponding service data obtaining party according to the sending object in the second request instruction.
S306, adjusting the first change data based on the reservation information carried in the second request instruction, wherein the reservation information is used for indicating whether the first change data is reserved in the change data file.
Optionally, in this application, after the first change data is sent, further according to the reservation information carried in the second request instruction and used for indicating whether to reserve the first change data in the change data file, whether to send the first change data is selected, and then the first change data is cleared.
In the method, after the first change data and the first position identifier are added to the change data file, the change data file added with the first change data and the first position identifier is synchronized to the local disk, and after the first change data is sent, whether the first change data is reserved or not is selected based on a second request instruction. By applying the technical scheme, after the data of the change of the data content in the relational database and the corresponding position identification are synchronized to the local disk, whether the first change data is reserved in the local disk for a long time or not can be selected based on the reserved information. Thereby the effective data information is stored in the local disk in a targeted way. Thereby reducing unnecessary losses.
Further optionally, in an embodiment of the present application, before S101 (acquiring the synchronization instruction), a specific embodiment is further included, as shown in fig. 4, including:
s401, a change data index table is established, and the change data index table is used for searching each change data.
Optionally, in the present application, a change data index table for searching each change data in the change data file may be first established. It can be understood that when the service data acquirer extracts the change data from the relational database from the electronic device, the defect of user experience degradation caused by too long query time is avoided because the change data is more. The service data acquirer can determine corresponding change data based on inquiring a pre-established change data index table. Thus saving inquiry time and improving working efficiency.
S402, acquiring a synchronous instruction.
S403, the first position identification is recorded in a change data index table.
Alternatively, the first location identifier for marking the location of the first change data in the change data file may be recorded in the change data index table. So that each service data acquirer can acquire corresponding change data by inquiring the change data index table.
S404, adding the first change data and a change data index table recording the first position identification to the change data file.
S405, synchronizing the added first change data and the change data file of the first position mark to the local disk.
In an alternative embodiment of the present application, as shown in fig. 5, first, the first change data may be acquired from the relational database, further, after the first change data is acquired, a first location identifier 21 corresponding to the first change data may be generated, and the first location identifier 21 may be recorded in the change data index table 11. Further, the change data index table 11 may be added to the change data file, and the change data file to which the first change data and the first location identifier are added may be synchronized to the local disk in a memory map file method mmap.
In the present application, a change data index table for searching each change data is first established, and after a first change data and a change data index table recorded with a first position identifier are added to a change data file, the change data file added with the first change data and the change data index table is synchronized to a local disk. By applying the technical scheme, after the data of the change of the data content in the relational database and the corresponding position identification are synchronized to the local disk, the service data acquisition party can find the corresponding change data by inquiring the pre-established change data index table. Therefore, the time for inquiring the data by the user is reduced, and the user experience is improved.

By applying the technical scheme, the corresponding position identification can be added to the data with changed data content in the relational database, and the changed data and the position identification are synchronized to the local disk. Therefore, the defect that the data cannot be stored for a long time due to the fact that the data are stored in the memory of the electronic equipment in the related art is avoided. Thereby improving user experience.
