Description
Technical Field
The invention relates to the technical field of computers, in particular to a cross-border multi-server information synchronization method, a cross-border multi-server information synchronization system and a storage medium.
Background
With the globalization of electronic commerce, cross-border e-commerce takes place. Currently, there is a problem in cross-border e-commerce websites: due to different network environments in different countries and regions around the world, especially those places with large spatial distance, the networks are unstable and have poor performance (the network delay is large), and the network access timeout phenomenon is serious. If the website data is placed on the domestic server, delay is very high when a foreign user (such as a consumer) accesses the website, and if the website data is placed on the foreign website, a domestic user (such as a merchant) accesses the website. Network performance is an important reason for affecting user experience, and thus, user experience is seriously affected.
For the above problems of poor performance and poor stability of the cross-border network, a solution is currently available to implement local unit deployment in various regions of the world, and the solution can thoroughly solve the problem of network performance. However, for many large websites, the core systems, including data centers, etc., are deployed in a local central computer room, and to implement the deployment in different places, especially in cross-border unitization, it is equivalent to copy one set of data centers in different places, and to implement a different-place double-active synchronization scheme, the deployment time is long, and the deployment cost is very high. Therefore, the cost of expanding the business overseas is very high, and particularly, the cost is hard to bear at the initial expansion stage of the business overseas.
Another solution is to set a plurality of servers, each of which provides services to users nearby, and the servers usually include a database supporting service processing and a server application (hereinafter, referred to as an application) for processing services, and the application can perform operations such as addition, deletion, and modification in the database according to various service requests of the users, and store the operations. In general, an application synchronizes to a cache of a server according to data changed in a database to improve data processing capability, so that data between the database and the cache needs to be consistent, and for a plurality of servers, data between databases of each server needs to be consistent, and data between the database and the cache in each server needs to be consistent.
However, during the information synchronization process, the interaction between the service terminals is too frequent, which increases the interaction complexity and network overhead. Therefore, how to simplify the interaction between the service ends and save the network resources is a technical problem that needs to be solved at present.

Example one
Referring to fig. 1, a first embodiment of the cross-border multi-server information synchronization method of the present invention is proposed, which comprises the following steps:
and S11, when detecting that the information change occurs in the first server or the second server, judging whether the information change needs to be synchronized immediately. If the real-time synchronization is required, go to step S12; if no immediate synchronization is required, the process proceeds to step S13.
In the embodiment of the present invention, the first service end and the second service end are two or more servers crossing the border (e.g., different regions, different countries, etc.), such as servers located in different continents, and in the embodiment, the first service end is located in china in asia, and the second service end is located in the united states in north america, for example.
In the embodiment of the invention, when the first server or the second server is detected to generate information change, the information change is not immediately synchronized, but whether the information change needs immediate synchronization is judged at first, and the immediate synchronization is performed only when the information change needs immediate synchronization, so that the interaction frequency between the servers can be reduced, and the network overhead and the interaction complexity are further reduced.
In the embodiment of the invention, the information change generally comprises two types of application operation change and data change. The application operation change includes edit page saving (related to menu, template, skin, card configuration, and the like), merchandise information change (such as merchandise basic information change, stock information change, and the like), album information change (such as album basic information change, merchandise shelving and deletion, and the like), shop information change (such as shop basic information change), shopping cart information change (such as shopping cart commodity change), checkout page information change, order information change (such as order state change), and the like.
Generally, when information change relates to situations such as information distribution, information real-time change and the like, the need of real-time synchronization is judged, such as commodity information change, checkout information change, order information change and the like; when the information change involves temporary saving of information, temporary non-release of information, etc., it is determined that immediate synchronization is not required, such as temporary saving of information by a user, editing and saving of information (such as shop template data) by a user, non-release, etc.
S12, controlling the first server and the second server to perform real-time synchronization.
In the embodiment of the invention, when the information change needs to be synchronized instantly, the first service end and the second service end are controlled to synchronize the current information change instantly. Specifically, when the information is changed into the application operation change, the application operation change is stored in the cache of the first server or the second server, and an instant synchronization request is sent to the second server or the first server; and when the information change is data change, storing the data change in a database of the first server or the second server, and sending an instant synchronization request to the second server or the first server.
For example:
when detecting that a first service terminal generates a first application operation change needing immediate synchronization, storing the first application operation change in a cache of the first service terminal, and sending an immediate synchronization request to a second service terminal; and when the second server detects the instant synchronization request, generating an instant refresh instruction, and updating the application operation (single page refresh) for sending change in the cache.
When detecting that a second server generates a second application operation change needing immediate synchronization, storing the second application operation change in a cache of the second server, and sending an immediate synchronization request to the first server; when the first server detects the instant synchronization request, an instant refresh command is generated, and the changed application operation (single page refresh) sent in the cache is updated.
When detecting that a first service end generates a first data change needing immediate synchronization, storing the first data change in a database of the first service end, and sending an immediate synchronization request to a second service end so as to synchronize the first data change in the database of the second service end; and when the second server detects the instant synchronization request, generating an instant refresh command, and updating the data sent and changed in the database.
When detecting that a second server generates a second data change needing immediate synchronization, storing the second data change in a database of the second server, and sending an immediate synchronization request to the first server so as to synchronize the second data change in the database of the first server; and when the first server detects the instant synchronization request, generating an instant refresh command, and updating the data sent and changed in the database.
And S13, controlling the first service end and the second service end to be synchronous within a preset time.
In the embodiment of the invention, when the information change does not need to be synchronized instantly, the first service end and the second service end are controlled to be synchronized within the preset time, for example, the whole page and data of the second service end or the first service end are refreshed within the preset time. Therefore, information which does not need to be updated immediately can be synchronized once after a period of time is accumulated, interaction times among the service ends are greatly reduced, and interaction frequency is reduced.
Further, in the embodiment of the present invention, when it is detected that the information of the first service end and the information of the second service end are not synchronized, the second service end is mainly used, and the information of the second service end is integrally synchronized to the first service end. That is, when the information synchronization has a problem, one server which is specified in advance is used as a main server, and the information synchronization is recovered through the main server, so that the information synchronization is prevented from being disordered, and the information consistency of the two servers is ensured. In this embodiment, the second service end is designated as the main service end for example, and actually, the first service end may also be designated as the main service end according to actual needs, which is not limited in the present invention.
Further, when the first service end and the second service end are detected to have synchronous abnormal information, the client flow corresponding to the first service end is switched from the first service end to the second service end. In the embodiment of the invention, a first service end and a second service end are respectively connected with different customer service end flows, for example, the first service end is connected with a seller client, the second service end is connected with a buyer client, and when the first service end and the second service end are detected to have synchronous abnormal information, the flow of the seller client is switched from the first service end to the second service end. That is, when the information synchronization is abnormal, one server which is specified in advance is used as a main server, and the main server is used for connecting the flow of all the customer servers, so that the information synchronization is prevented from being disordered, and the information consistency of the two servers is ensured. In this embodiment, the second service end is designated as the main service end for example, and actually, the first service end may also be designated as the main service end according to actual needs, which is not limited in the present invention.
Further, in the embodiment of the present invention, different initial values and the same step size are set for the self-increment IDs of the databases of the first server and the second server, for example, different initial values are set for the two servers in an odd-even distribution manner, and the step sizes are both set to 2, so that the complexity of the data collision and the information synchronization of the dual-master-dual-write master key is reduced, the data synchronization failure or error caused by the data collision of the master key of the database when the database synchronization is performed by the servers is prevented, and the error rate of the data synchronization is reduced. Furthermore, the unique identification code is used as a distributed main key of the database, so that the error rate of data synchronization is further reduced.
According to the cross-border multi-server information synchronization method, the generated information changes are distinguished, the server sides are controlled to be synchronized immediately only when the information changes which need to be synchronized immediately, and the server sides are controlled to be synchronized within the preset time when the information changes which do not need to be synchronized immediately, so that the interaction times among the server sides are reduced, the interaction frequency among the server sides is reduced, the effects of simplifying the interaction among the server sides and saving network resources are achieved, and the cross-border multi-server information synchronization method is an information synchronization scheme which is simple and convenient to interact and saves network resources.
Example two
Referring to fig. 2, a second embodiment of the cross-border multi-server information synchronization method of the present invention is proposed, which comprises the following steps:
s21, when detecting that the first server or the second server has changed information, determining whether the change is an application operation change. If the application operation change is made, the flow proceeds to step S22; if the operation change is not to be applied, the process proceeds to step S24.
The embodiment of the invention limits the operation authority of the server. For example, a seller (merchant) client accesses a mysql database of a first server, a buyer (consumer) client accesses a mysql database of a second server, and the seller client/buyer client service is divided to insert operation authority into a mysql table, that is, the first server can only respond to application operation change of the seller client (e.g. defined as first application operation change), and the second server can only respond to application operation change of the buyer client (e.g. defined as second application operation change).
And S22, judging whether the first server or the second server has the operation authority. When there is no operation right, the flow proceeds to step S23; when there is an operation right, the flow proceeds to step S24.
In the embodiment of the invention, when the information is changed into the application operation change, whether the first server or the second server has the operation authority is further judged.
For example, when the first application operation change is generated by the first service end, it is determined that the first service end has the operation authority; and when the first service end generates the operation change of the second application, judging that the first service end has no operation authority.
For another example, when the second application operation is changed, the second server is determined to have the operation authority; and when the second server generates the first application operation change, judging that the second server has no operation authority.
And S23, rejecting the application operation change.
In the embodiment of the invention, when the first service end or the second service end has no operation right, the application operation change is refused.
For example, when the first server generates a second application operation change, the second application operation change is rejected, and the authority of the first server for the second application operation change is limited.
For another example, when the second server generates the first application operation change, the first application operation change is rejected, and the permission of the second server for the first application operation change is limited.
S24, judging whether the information change needs immediate synchronization. If the real-time synchronization is required, go to step S25; if no immediate synchronization is required, the process proceeds to step S26.
When the information change is not the application operation change or the first server or the second server has an operation right for the application operation change although the information change is the application operation change, further judging whether the information change needs immediate synchronization.
S25, controlling the first server and the second server to perform real-time synchronization.
And S26, controlling the first service end and the second service end to be synchronous within a preset time.
Steps S24-S26 in this embodiment are the same as steps S11-S13 in the first embodiment, respectively, and are not repeated herein.
According to the cross-border multi-server information synchronization method, the operation authority of the server is limited, and each server can only respond to the application operation change corresponding to the authority of the server, so that the data conflict of double main keys and double write main keys and the complexity of information synchronization are further reduced, and the error rate of data synchronization is further reduced.
Embodiments of the present invention also provide an information synchronization system, which includes a memory, a processor, and at least one application program stored in the memory and configured to be executed by the processor, where the application program is configured to perform a cross-border multi-server information synchronization method. The cross-border multi-server information synchronization method described in this embodiment is the cross-border multi-server information synchronization method according to the above embodiment of the present invention, and is not described herein again.
The embodiment of the invention also provides a computer readable storage medium, wherein an information synchronization program is stored on the computer readable storage medium, and when the information synchronization program is executed by a processor, the steps of the information synchronization method of the cross-border multi-service end are realized. The cross-border multi-server information synchronization method described in this embodiment is the cross-border multi-server information synchronization method according to the above embodiment of the present invention, and is not described herein again.

These devices may be specially designed and manufactured for the required purposes, or they may comprise known devices in general-purpose computers. These devices have stored therein computer programs that are selectively activated or reconfigured.
