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 embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

It should be noted that, in this document, 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 an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

In the related technology, the service data of the cloud network can be stored by using a live-active network architecture, and when the service is processed, the data of the master copy needs to be updated first, then the data of the slave copy needs to be updated synchronously, and finally the update result is fed back to the service system through the master copy. At present, two copies in a dual active network architecture are respectively arranged in different available areas, each available area can be provided with a corresponding service system, and the data transmission delay in the available areas is small, so that the data processing efficiency in the same available area is high. However, when the receiving service system and the primary replica are located in different available areas, data updating, synchronization, and feedback need to be processed across the available areas multiple times, so that the delay of data transmission is large, and the efficiency of data processing is low.

The service processing procedure will be described with reference to fig. 1.

Fig. 1 is a schematic view of a service processing process provided in an embodiment of the present application. Referring to fig. 1, the system includes a service system a, a service system B, a primary database and a backup database. The service system A and the main database are located in the available area A, and the service system B and the standby database are located in the available area B. When the service system B receives the data processing request, the service system B needs to send the data processing request to the master database, so that the master database updates the data. After the updating of the main database is finished, the main database sends a data synchronization request to the standby database, the standby database updates data according to the data synchronization request and returns a confirmation message to the main database, and when the main database receives the confirmation message sent by the standby database, the main database sends a service processing request finishing message to the service system. Thus, 1 service processing request requires 2 network requests across the available area, which results in inefficient data processing.

In order to solve the technical problem of low efficiency of data processing in the related art, an embodiment of the present application provides a data processing method, in which a backup database receives a data processing request sent by a service system, where the backup database is in the same available area as the service system, the backup database obtains a request type of the data processing request, sends data corresponding to the data processing request to the service system when the request type is a read operation type, sends the data processing request to a main database when the request type is a write operation type, and receives a data synchronization request corresponding to the data processing request sent by the main database, where the backup database and the main database are in different available areas, and the backup database updates data according to the data synchronization request and sends a data processing end message to the service system. Therefore, when the service system and the main database are in different available areas, the service system can firstly send a data processing request to the standby database, and forwards the data processing request to the main database through the standby database, and after the standby database updates data according to the data synchronization request of the main database, the standby database sends a data processing end message to the service system.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a schematic flowchart of a data processing method according to an embodiment of the present disclosure. Referring to fig. 2, the method may include:

s201, receiving a data processing request sent by a service system by a standby database.

The execution subject of the embodiment of the application may be a standby database, or may be a data processing device disposed in the standby database. The data processing device may be implemented by software, or may be implemented by a combination of software and hardware.

Alternatively, the backup database may be a backup copy of the live-active network architecture. In the dual active network architecture, the same data may include two copies (a primary copy and a backup copy), and both copies may provide read-write services to the outside. For example, the service system may read data from the backup copy, or may update data in the backup copy.

Optionally, the data processing request is used to process data in the database. For example, the data processing request may read data in the database, update data in the database, or write new data in the database. The service system can receive a data processing request sent by a user side. For example, the service system may receive a data update request (e.g., a request for creating an account, modifying a password, etc.) sent by the user side, and process the data update request.

Optionally, the standby database is in the same available area as the service system. The available area refers to a physical area in which power and a network are independent in the same geographical area. For example, one available area is not affected by the failure of other available areas, and multiple available areas can be included in the same geographic area, and different available areas are physically isolated, but intranet intercommunication can ensure the independence of the available areas and reduce the network delay in the available areas. For example, in order to reduce network latency, a service system may be provided in each available area, and if a service system in the available area where the backup database is located receives a data processing request, it is determined that the backup database is in the same available area as the service system, and if a service system in another available area than the available area where the backup database is located receives a data processing request, it is determined that the backup database is in a different available area from the service system.

S202, the standby database sends the data processing request to the main database.

Alternatively, the master database may be the master copy of the live-active network architecture. For example, data in the dual active network architecture may include a primary copy and a secondary copy, and the security of the data may be improved by storing the data through the two copies.

Optionally, the standby database is in a different available area than the primary database. For example, the same geographical area includes an available area a and an available area B, and if the spare database is provided in the available area a, the primary database may be provided in the available area B, and if the spare database is provided in the available area B, the primary database may be provided in the available area a, and by providing two copies of the same data in different available areas, the security of data storage may be improved (e.g., when one available area fails, a copy in the other available area may also be used).

Optionally, the data processing priority of the primary database is greater than the data processing priority of the standby database. For example, when the service system receives a data processing request, the data processing priority of the primary database is higher than that of the standby database, so that the data of the primary database needs to be processed preferentially, and after the data processing of the primary database is finished, the data of the standby database is processed. For example, in the process of writing or updating data, in order to ensure that a transaction (transaction) is correct and reliable, atomicity (or inseparability), consistency (consistency), isolation (independence), and durability (durability) that data processing must have are required, and since a service has a demand for data to cross an available area ACID, the writing or updating operation of data needs to be synchronized consistently between different available areas, data processing may be performed on a primary database first, and then data processing may be performed on a standby database.

Optionally, the data processing request may be sent to the master database according to the following feasible implementation manners: and the standby database acquires the request type of the data processing request, and sends the data processing request to the main database according to the request type. Wherein the request type is a read operation type or a write operation type. Alternatively, a data processing request of the read operation type may read data in the database. For example, if the request type of the data processing request is a read operation type, the data processing request may read data in the database. For example, if the data processing request is used to query data in a database, the request type of the data processing request is a read operation type.

Alternatively, a write operation type data processing request may alter data in the database. For example, if the request type of the data processing request is a write operation type, the data processing request may change data in the database. For example, if the data processing request is a change password, the request type of the data processing request is a write operation type.

Optionally, the standby database sends a data processing request to the primary database according to the request type, specifically: and when the request type is a read operation type, the standby database sends data corresponding to the data processing request to the service system. For example, if the request type of the data processing request is a read operation type, it indicates that the data processing request does not change the data in the database, and does not add new data to the database, so that the standby database can send the data corresponding to the data processing request to the service system, and does not need to send the data processing request to the primary database, thereby reducing the delay of data processing and improving the efficiency of data processing.

And when the request type is a write operation type, the standby database sends a data processing request to the main database. For example, if the request type of the data processing request is a write operation type, it indicates that the data processing request needs to change the data in the database (e.g., data update, data addition, etc.), and since the data priority of the primary database is greater than the data priority of the standby database, the standby database needs to send the service processing request to the primary database so that the primary database updates the data according to the data processing request.

Optionally, before the standby database sends the data processing request to the primary database, the data processing method shown in fig. 2 further includes: the standby database adds a request identifier to the data processing request. For example, when the standby database receives a data processing request sent by a service system, if the data processing request needs to be forwarded to the primary database, the standby database may add a request identifier to the data processing request, so that the primary database updates data according to the request identifier.

S203, receiving a data synchronization request corresponding to the data processing request sent by the main database.

Optionally, the data synchronization request includes data updated by the master database according to the data processing request. For example, if the master database updates data a to data B in the master database according to the data processing request, the data synchronization request includes information for updating data a to data B.

Optionally, the data synchronization request may include a request identifier. For example, after the primary database updates the data according to the data processing request, the primary database may add a request identifier to the data synchronization request, and when the backup database receives the data synchronization request, the backup database determines the data to be updated according to the request identifier. For example, the standby database has sent a data processing request a and a data processing request B to the primary database, where the data processing request a includes a request identifier a, and the data processing request B includes a request identifier B, and if the data synchronization request received by the standby database includes the request identifier a, the standby database determines that the primary database has finished processing the data processing request a, and then updates the data.

Next, a procedure of receiving a data synchronization request will be described with reference to fig. 3.

Fig. 3 is a schematic diagram of receiving a data synchronization request according to an embodiment of the present application. See fig. 3, which includes a primary database and a backup database. Wherein, the standby database sends a data processing request to the main database. And when the main database receives the data processing request sent by the standby database, the main database processes the data according to the data processing request and sends a data synchronization request to the standby database.

And S204, the standby database updates the data according to the data synchronization request.

Optionally, when the standby database receives the data synchronization request, the data may be updated according to the data synchronization request. For example, when the standby database receives the data synchronization request, the data in the standby database may be updated according to the data to be synchronized in the data synchronization request.

And S205, sending a data processing end message to the service system.

Optionally, after the data is updated by the standby data, a data processing end message may be sent to the service system, so that the service system determines that the data corresponding to the data processing request is updated in the main database and the standby database. For example, the service system receives a data processing request to update data a to data B, and if the service system receives a data processing end message sent by the standby database, the service system determines that both the primary database and the standby database have updated data a to data B.

The embodiment of the application provides a data processing method, wherein a standby database receives a data processing request sent by a service system, the standby database and the service system are in the same available area, the standby database acquires a request type of the data processing request, when the request type is a write operation type, the standby database can send the data processing request to a main database and receive a data synchronization request corresponding to the data processing request sent by the main database, the standby database and the main database are in different available areas, and the standby database updates data according to the data synchronization request and sends a data processing end message to the service system. According to the method, when the service system and the main database are in different available areas, the service system can firstly send a data processing request to the standby database, and forwards the data processing request to the main database through the standby database, and after the standby database updates data according to the data synchronization request of the main database, the standby database sends a data processing end message to the service system, so that the data processing request can be added into the data synchronization link, the data processing request is associated with the synchronization link, the main database and the standby database can be updated synchronously only by crossing the available areas once, the data transmission delay is further reduced, and the data processing efficiency is improved.

On the basis of the embodiment shown in fig. 2, another data processing method will be described below with reference to fig. 4.

Fig. 4 is a schematic flowchart of another data processing method according to an embodiment of the present application. Referring to fig. 4, the process of the method includes:

s401, the service system receives a data processing request.

The execution subject of the embodiment of the present application may be a service system, and may also be a data processing apparatus set in the service system. The data processing device may be implemented by software, or may be implemented by a combination of software and hardware.

Optionally, the data processing request includes data to be processed. For example, if the data processing request is used to read data, the data to be processed is the identifier of the read data, and if the data processing request is used to update the data, the data to be processed is the data to be updated. For example, if the data processing request is used to add data a and data B in the database, the data to be processed is data a and data B.

S402, the service system acquires a first available area where the main database is located and a second available area where the standby database is located.

Optionally, the first usable area is different from the second usable area. For example, the primary database may be located in a different available area than the standby database. For example, when the service system receives a data processing request, the service system may obtain an identifier of an available area where the primary database is located and an identifier of an available area where the standby database is located, thereby determining the first available area and the second available area.

S403, the service system sends a data processing request according to the first available area and the second available area, and receives a data processing request end message.

Optionally, the service system may send the data processing request according to the following feasible implementation manners: and acquiring a third available area where the service system is located. And if the first available area is the same as the third available area, the service system sends a data processing request to the master database. For example, if the first and third available areas are the same, it indicates that the master database and the service system are located in the same available area, and the service system may send a data processing request to the master database. And if the second available area is the same as the third available area, the service system sends a data processing request to the standby database. For example, if the second available area is the same as the third available area, it indicates that the backup database is located in the same available area as the service system, and the service system may send a data processing request to the backup database.

Optionally, if the service system sends a data processing request to the primary database, the primary database processes the data according to the data processing request, and sends a data synchronization request to the standby database, so that the standby database processes the data according to the data synchronization request.

Optionally, if the first available area is the same as the third available area, the service system receives a data processing request end message sent by the master database. For example, if the first available area is the same as the third available area, it indicates that the primary database and the service system are located in the same available area, after the backup database synchronizes data, a response message may be sent to the primary database, and the primary database sends a data processing request end message to the service system according to the response message, so that data can be processed only by one access across the available areas, thereby improving the efficiency of data processing.

And if the second available area is the same as the third available area, the service system receives a data processing request end message sent by the standby database. For example, if the second available area is the same as the third available area, it indicates that the backup database and the service system are located in the same available area, and after receiving the data synchronization request of the primary database, the backup database may perform synchronization processing on the data and send a data processing request end message to the service system, so that the data may be processed only by one access across the available areas, thereby improving the efficiency of data processing.

The embodiment of the application provides a data processing method, wherein a service system receives a data processing request, and sends the data processing request and receives a data processing request ending message according to a first available area and a second available area. Therefore, when the service system receives the data processing request, the service system can send the data processing request to the database in the same available area and receive the data processing request ending message sent by the database in the same available area, and the data synchronous updating can be carried out on the main database and the standby database only by one-time network access crossing the available area no matter the database in the same available area is the main database or the standby database, so that the data transmission delay is reduced, and the data processing efficiency is improved.

On the basis of any of the above embodiments, the following describes a procedure of the above data processing method with reference to fig. 5.

Fig. 5 is a schematic process diagram of a data processing method according to an embodiment of the present application. Referring to fig. 5, the system includes a service system a, a service system B, a primary database and a backup database. The service system A and the main database are located in the available area A, and the service system B and the standby database are located in the available area B. And when the service system B receives the service processing request, the service system B sends the data processing request to the standby database. And when receiving the data processing request, the standby database sends the data processing request to the main database.

Referring to fig. 5, when the primary database receives a data processing request, the primary database updates data according to the data processing request, and when the primary database finishes updating the data, the primary database may send a data synchronization request to the backup database. And the standby database performs data synchronization updating according to the data synchronization request and sends a data processing request ending message to the service system. Therefore, the data processing request is added into the data synchronization link, the data processing request is associated with the data synchronization link, and the data synchronization update can be carried out on the main database and the standby database only by crossing the available area once, so that the data transmission delay is reduced, and the data processing efficiency is improved.
