In addition, the technical scheme of the application can acquire, store, use, process and the like the data, which accords with the relevant regulations of national laws and regulations.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
It should be noted that in this document, relational terms such as "first" and "second" and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
In order to solve the problems in the prior art, the embodiment of the application provides a data synchronization method, a device, equipment, a medium and a product. The following first describes a data synchronization method provided by an embodiment of the present application.
Fig. 1 is a schematic flow chart of a data synchronization method according to an embodiment of the present application. As shown in fig. 1, the method specifically may include the following steps:
step 101, a first device sends a query request to a second device, wherein the query request is used for querying first version information of an object to be called in the first device, and the object to be called is an object marked as a preset mark;
the application can be applied to data synchronization between two devices, for example, a payment system and a merchant background system use terminal data of the same merchant to complete payment collection and merchant refund. The payment system can be a first device, the merchant background system can be a second device, and the process of payment collection and merchant refund is the process of data synchronization.
The object to be called can be data to be called, and the preset mark can adopt characters as marks. As an example, the object to be invoked with higher invoking heat may be marked by a preset mark, so that the first device may actively send a query request to the second device only when detecting that the invoking heat of the object to be invoked is higher, so as to complete subsequent data synchronization.
As another example, the object to be invoked with higher importance may be marked by a preset mark, so that the first device may actively send a query request to the second device only when detecting that the importance of the invoking object is higher, so as to complete the data synchronization after that.
Step 102, a second device receives a query request sent by a first device, where the query request is used to query first version information of an object to be invoked in the first device, and the object to be invoked is an object marked as a preset mark;
step 103, the second device sends first version information corresponding to the query request, wherein the first version information is recorded in a main register of the second device;
in the present embodiment, the main registry is a data registry, which can be used to register the business category of data, unique identification of classified data (e.g., customer ID, user number, merchant number), version information. The method is divided into a main register and a subsidiary register. The main register is maintained by the second device, and data version information of data in the second device is recorded; the secondary registry is maintained by the first device and records version information of the data currently in use by the second device.
In step 103, as an example, the second device may determine the first version information corresponding to the query request based on the service class and the unique identification of the classification data in the query request; and the second equipment sends the first version information corresponding to the query request.
Step 104, the first device receives the first version information sent by the second device, and the first version information is recorded in a main register of the second device;
step 105, the first device sends a call request to the second device when the second version information of the object to be called recorded in the secondary registry of the first device is different from the first version information, where the call request is used to obtain the latest data of the object to be called in the second device;
it will be appreciated that, since the first version information and the second version information are different, it is indicated that the called object in the first device is updated, so that the version information in the main registry is changed, and therefore, the first device needs to call the second device with the called object of the latest version to complete data synchronization between the first device and the second device.
Step 106, the second device sends the latest data of the object to be called corresponding to the call request to the first device;
the calling request comprises the unique identification of the service class and the classification data of the object to be called;
as one example, the second device determines the latest data of the object to be invoked stored in the second device based on the service class and the unique identification of the classification data;
the second device sends the latest data of the object to be invoked to the first device.
Step 107, the first device updates the original data of the object to be invoked stored on the first device by adopting the latest data of the object to be invoked, and updates the version information of the object to be invoked recorded in the auxiliary register into the first version information;
after receiving the latest data of the object to be invoked sent by the second device, the first device may store the latest data in the database, and delete the data of the original object to be invoked or directly overlay the latest data with the latest data, so as to complete updating of the data of the object to be invoked in the first device.
Additionally, in some embodiments, the data synchronization method may further include the steps of:
Step a, a first device sends a query request to a second device, wherein the query request is used for querying a first update time of an object to be called in the first device, and the object to be called is an object marked as a preset mark;
step b, the second device receives a query request sent by the first device, wherein the query request is used for querying a first update time of an object to be called in the first device, and the object to be called is an object marked as a preset mark;
step c, the second equipment sends a first updating time corresponding to the query request, and the first updating time is recorded in a main register of the second equipment;
step d, the first device receives the first updating time sent by the second device, and the first updating time is recorded in a main register of the second device;
step e, the first device sends a calling request to the second device when the second updating time of the object to be called recorded in the auxiliary register of the first device is different from the first updating time, wherein the calling request is used for acquiring the latest data of the object to be called in the second device;
step f, the second device sends the latest data of the object to be called corresponding to the call request to the first device;
And g, updating the original data of the object to be called stored on the first device by adopting the latest data of the object to be called, and updating the updating time of the object to be called recorded in the auxiliary register as the first updating time.
In this embodiment, the first update time may be the latest update time of the called object recorded in the primary registry, and the second update time may be the current update time of the called object recorded in the secondary registry. Under the condition that the first updating time is the same as the second updating time, the called object in the second device is not updated; when the first update time is different from the second update time, it is indicated that the invoked object in the second device is updated, and data synchronization between the first device and the second device is required.
In the application, the auxiliary register is established in the first equipment, the main register is established in the second equipment, the version information or the updating time of the calling object is recorded in the main register and the auxiliary register, and the first equipment can call the latest data to the second equipment under the condition that the version information in the main register and the version information in the auxiliary register are different through the information interaction between the main register and the auxiliary register so as to realize the data synchronization between the first equipment and the second equipment, thereby reducing the data synchronization frequency between the first equipment and the second equipment and improving the utilization rate of the resources and network resources of the equipment.
In an embodiment of the present application, after the receiving the first version information sent by the second device, the method further includes:
and acquiring the data of the object to be called from the first device under the condition that the second version information of the object to be called recorded in the auxiliary register of the first device is the same as the first version information.
It can be understood that in the case that the first version information and the second version information are different, it is indicated that the object to be invoked is not updated, and the first device does not need to invoke the latest data of the object to be invoked to the second device, so that the data of the object to be invoked can be invoked directly from the database in the first device.
In this embodiment, when the first version information and the second version information are different, the data is directly called from the first device, so that the number of times that the first device sends a call request to the second device can be reduced, the synchronization frequency between the first device and the second device is reduced, and the working efficiency of the first device is improved.
In an embodiment of the present application, before the sending the query request to the second device, the method further includes:
receiving call hotness of a call object sent by second equipment, wherein the call object is stored in the first equipment and the second equipment;
Adding the preset mark to the calling object under the condition that the calling heat is greater than or equal to a first preset threshold value;
acquiring a service to be processed of the first equipment;
and determining an object to be called corresponding to the service to be processed in the call objects.
In this embodiment, the call object is stored in the first device and the second device, and it is understood that the call object is stored in the first device and the second device, and version information of the call object in the first device and version information of the call object in the second device may be different. The number of the call objects may be 1 or plural, and the present application is not limited herein.
And under the condition that the calling heat is equal to or higher than a first preset threshold value, the calling heat of the calling object is higher, namely the preset mark can be added to the calling object, and after the preset mark is added, the calling object is higher. The calling heat can be represented by the calling frequency, and the first preset threshold value corresponds to the calling heat and can also be represented by the frequency threshold value.
The service to be processed is the service being processed by the first device, and the service to be processed can be obtained by monitoring an operation instruction of a user on the first device. In an exemplary embodiment, when the first device is a payment system and the second device is a merchant background system, the payment system performs a payment operation to the merchant background system, and the payment operation is a service to be processed of the first device.
When the first device processes the service to be processed, various data are required to be related, and the object to be invoked is various data related to the service to be processed. For example, when the service to be processed is a payment operation, the object to be invoked may be a name of a merchant, an account number of the merchant, or the like.
In this embodiment, by adding a preset flag indicating the heat degree to the call object and determining the object to be called in the call object, the first device can flag the call object with high heat degree, and further can actively synchronize data to the second device under the condition that the heat degree of the call object is high.
In an embodiment of the present application, before the receiving the query request sent by the first device, the method further includes:
and under the condition that the updating of the calling object in the second equipment is detected, recording the updated first version information of the calling object into a main register book in the second equipment, wherein the calling object comprises any calling object in all calling objects stored in the second equipment.
It can be understood that, since the data stored in the second device is updated, that is, the calling object is updated, when the second device detects that the calling object is updated, the second device needs to record the updated first version information of the calling object into the main register, so that the first device can determine whether the object to be called needs to be updated based on the version information recorded in the main register and the auxiliary register, and the synchronization frequency between the first device and the second device can be reduced by updating the main register, thereby improving the utilization rate of system resources and network resources.
In an embodiment of the present application, after the first version information of the updated calling object is recorded in the main registry in the second device in the case that the updating of the calling object in the second device is detected, before the receiving the query request sent by the first device, the method further includes:
acquiring the historical call frequency of the call object, wherein the historical call frequency is obtained based on the number of times that the call object is called in a preset period;
determining the calling heat of the calling object based on the historical calling frequency and a preset relation between the historical calling frequency and the calling heat;
sending the call hotness to the first device; and
and sending the calling object to the first equipment under the condition that the calling heat is greater than or equal to a second preset threshold value.
In this embodiment, the history call frequency is the number of times of calling the call object in a preset period, where the preset period may be a time interval from the time when the call object is called for the first time to the time when the call object is called for the last time, or a time interval from the time when the call object is called for the first time to the current time, or may be a fixed time period.
The historical call frequencies are in one-to-one correspondence with call hotness, and in the process of determining the call hotness of the call object, the corresponding call hotness can be searched based on the historical call frequencies. For example, the historical call frequency is 1 time/min, and the call heat is 5 if the heat corresponding to 1 time/min is found to be 5 through the preset relation. It should be noted that the historical call frequency may be an interval, and each interval corresponds to a call hotness. After determining the call hotness of the surrogate object in the second device, the call hotness may be sent to the first device.
In some embodiments, the call hotness may also be obtained based on a history update number, and in particular, the history update number of the call object may be obtained; and determining the call hotness of the call object based on the history updating times and the preset relation between the history updating times and the call hotness. Wherein the historical update times can be obtained based on the update times of the calling object in the time interval of the first update time and the last update time. The more frequently the call object is updated, the more important the call object is, so that the call hotness of the call object can be obtained based on the historical update times of the call object, the more the historical update times are, the higher the call hotness is, and otherwise, the lower the call hotness is.
In order to reduce the number of call requests sent by the first device, therefore, the second device may actively send the call object to the first device to make the first device call when the call hotness is greater than or equal to the second preset threshold. The second preset threshold is used for judging whether the calling heat is higher, and under the condition that the calling heat exceeds the second preset threshold, the first equipment is indicated to call the calling object frequently, so that the second equipment actively sends the calling object with higher heat to the first equipment, calling requests of the first equipment can be reduced, the working efficiency of the first equipment and the second equipment is improved, and the utilization rate of system resources and network resources is improved.
In an embodiment of the present application, after determining the call hotness of the call object based on the historical call frequency and the preset relationship between the historical call frequency and the call hotness, the method further includes:
acquiring the update times of the calling object under the condition that the calling heat is smaller than the second preset threshold value;
and sending the calling object to the first equipment under the condition that the updating times are larger than or equal to a preset third threshold value.
In order to further reduce the call request of the first device, avoid frequent call of the first device and generate a large number of repeated data requests, in this embodiment, when the call hotness is smaller than the second preset threshold, the call object may be sent to the first device according to the accumulated update times of the call object. It should be noted that, when the number of updates reaches the preset third threshold, the calling object is illustrated to be in a frequently updated state. Thus, the call object may be sent to the first device, thereby reducing call requests by the first device.
