[0030] The example embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Figure 1 It is a system block diagram of a parallel processing method and apparatus shown according to an exemplary embodiment.

[0032] Server 105 may be a server that provides various services, such as a background management server (merely for example) that supports a parallel processing system for operations performed by users using terminal devices 101, 102, and 103. The background management server may analyze and process data such as received parallel processing requests, and feedback the processing results (such as the change results of the target virtual account in the database - merely for example) to the terminal devices.

[0033] Server 105 may, for example, receive data processing requests for a target virtual account as separate parallel threads; the parallel threads read the value of the target virtual account from the database as a first value; after the parallel processing thread determines a parallel processing sub-result based on the first value, it reads the value of the target virtual account from the database as a second value; in response to the data processing request, the parallel thread changes the value of the target virtual account in the database based on the parallel processing sub-result, the first value, and the second value.

[0034] According to the parallel processing method and system provided by the embodiments of the present disclosure, in a parallel processing environment, when a parallel thread receives a data processing request, it reads the value of the target virtual account from the database as a first value, and during the process where a certain parallel processing thread determines a parallel processing sub-result based on the first value, since the value of the virtual resources of the target virtual account in the database may be changed by other parallel processing threads through write operations, the certain parallel processing thread reads the value of the target virtual account in the database again as a second value, and changes the value of the target virtual account in the database according to the comparison result of the first value and the second value. It can ensure data consistency in a distributed environment and avoid the phenomenon of concurrent execution result conflicts caused by the characteristics of isolated execution of concurrent threads with each other.

[0035] Figure 2 It is a flowchart of a parallel processing method shown according to an exemplary embodiment. The parallel processing method provided by the embodiments of the present disclosure can be executed by any electronic device with computing and processing capabilities, such as terminal devices 101, 102, 103 and / or server 105. In the following embodiments, the server executing the method is taken as an example for illustration, but the present disclosure is not limited thereto. The parallel processing method provided by the embodiments of the present disclosure is applied to a parallel processing system, and the parallel processing system may include multiple parallel threads. The parallel processing method may include steps S202 to S208.

[0036] As Figure 2 shown, in step S202, each parallel thread respectively receives a data processing request for a target virtual account.

[0037] In the embodiments of the present disclosure, each parallel thread may separately receive different data processing requests for a target virtual account. For example, the data processing request may be triggered, for example, by an operation of a user associated with the target virtual account. The user associated with the target virtual account refers to a user whose operation will trigger a change in the virtual resource value in the target virtual account. Taking an online payment scenario as an example, when multiple users associated with the target virtual account trigger data processing requests for the target virtual account through operations, the multiple data processing requests may be separately received by each parallel thread.

[0038] In step S204, the parallel thread reads the first value of the target virtual account from the database.

[0039] In the embodiments of the present disclosure, the first value of the target virtual account may be stored in the database. In an online payment scenario, the first value of the target virtual account may be the quantity of virtual resources held by the user associated with the target virtual account.

[0040] In step S206, after the parallel processing thread determines the parallel processing sub-result according to the first value, it reads the second value of the target virtual account from the database.

[0041] In the embodiments of the present disclosure, during the process of the parallel processing thread determining the parallel processing sub-result, the virtual resource value corresponding to the target virtual account in the database may be changed after being written by other threads. Therefore, the second value may be different from the first value.

[0042] In an exemplary embodiment, the data processing request may include a logical judgment task for a logical judgment object. Among them, when the parallel processing thread determines the parallel processing sub-result according to the first value, the parallel thread may execute the logical judgment task for the logical judgment object to obtain a logical judgment result; if the logical judgment result is passed, the target operation value is determined according to the logical judgment result; the parallel processing sub-result of the parallel thread is determined according to the first value and the target operation value.

[0043] Among them, the logical judgment object may be the initial payment price in an online payment scenario, such as but not limited to the price of medicine, hospitalization expenses, pathological examination expenses, etc. The logical judgment task may be whether to meet the full reduction, discount, whether to use a coupon, etc. Different parallel threads may be used to execute different logical judgment tasks. For example, when it is considered that the current medicine meets the full reduction during the execution of the logical judgment task, it may be considered that the logical judgment result is passed, otherwise it is not passed. When the logical judgment result is passed, the final price (i.e., the target operation value) may be determined according to the medicine price and the full reduction activity, and the parallel processing sub-result is determined according to the difference between the first value and the final price (i.e., the target operation value). For example, the parallel processing sub-result may be used as the remaining quantity of virtual resources in the target virtual account after the final selling price of the medicine is paid.

[0044] In an exemplary embodiment, when the logical judgment result fails, it is determined that the parallel processing sub-result of the parallel processing processor fails.

[0045] In step S208, in response to the data processing request, the parallel thread changes the value of the target virtual account in the database according to the parallel processing sub-result, the first value, and the second value.

[0046] According to the parallel processing method provided by the embodiments of the present disclosure, in a parallel processing environment, when a parallel thread receives a data processing request, it reads the value of the target virtual account from the database as the first value. During the process that a certain parallel processing thread determines the parallel processing sub-result according to the first value, since the value of the virtual resource of the target virtual account in the database may be changed by other parallel processing threads through write operations, the certain parallel processing thread reads the value of the target virtual account in the database again as the second value, and changes the value of the target virtual account in the database according to the comparison result of the first value and the second value. It can ensure data consistency in a distributed environment and avoid the phenomenon of concurrent execution result conflicts caused by the characteristics of isolated execution of concurrent threads with each other.

[0047] In an exemplary embodiment, in step S208, if the first value is equal to the second value, the parallel processing sub-result can be written into the database as the updated value of the target virtual account.

[0048] Among them, if the first value is equal to the second value, it can be determined that during the process that the parallel thread determines the parallel processing sub-result according to the first value, no other parallel thread has performed a write operation on the value of the target virtual account in the database. Therefore, it can be determined that there is no phenomenon of concurrent execution result conflict, and the parallel processing sub-result of the certain parallel thread can be directly written into the database. If the first value is different from the second value, it is determined that the parallel thread execution fails and retries. In this embodiment, only based on the comparison of the first value and the second value, the phenomenon of concurrent execution result conflict can be avoided, and it can meet the rapid delivery of ToB business construction.

[0049] For another example, if the parallel processing sub-result of the parallel thread fails, the change to the value of the target virtual account in the database is stopped.

[0050] Figure 3 It is a flowchart of a parallel processing method shown according to an exemplary embodiment. The parallel processing method 30 provided by the embodiments of the present disclosure may include steps S302 to S306.

[0051] In an embodiment of the present disclosure, a deduction service for purchasing drugs is executed by one of multiple parallel threads. In the process of purchasing drugs, the balance of the patient's account needs to be queried and modified according to the drug price. The general business process includes the following steps.

[0052] As Figure 3 shown, in step S302, the existing balance of the user ($old_money = 100) is queried from the database according to the user primary key ($user_id). Among them, the existing balance is the value of the target virtual account read from the database, that is, the first value.

[0053] In step S304, the business layer calculates the logical judgment tasks of the business according to actual needs. The logical judgment tasks can be, for example: whether there is a discount, whether there is a full reduction.

[0054] a) If the drug has a discount (assumed to be 20% off), then the parallel processing sub-result $new_money = $old_money - drug price * 80% is used as the final actual balance after the user purchases the drug.

[0055] b) If a full reduction is required (assumed to be a full reduction of 20), then the parallel processing sub-result $new_money = $old_money - (drug price - 20) is used as the final actual balance after the user purchases the drug.

[0056] In step S306, the value of the target virtual account in the database is updated to the final actual balance, and the obtained result is updated and written into the database. As Figure 3 shown, assuming that the parallel processing sub-result obtained after executing the logical judgment task is 80, then the parallel processing sub-result can be used as the updated value of the updated target virtual account.

[0057] In the case of low concurrency Figure 3 the solution shown in the figure is okay, but as the concurrency increases, the problem of data inconsistency will occur. The reasons for concurrent conflicts are illustrated by the following examples.

[0058] Taking Figure 3 the business scenario mentioned as an example, when multiple patients related to the target virtual account purchase drugs, three logical judgment tasks are triggered simultaneously in a distributed environment. For example: 1. Logical judgment task A has a 20% discount; 2. Logical judgment task B has a full reduction activity, a full reduction of 10 for every 100; 3. Logical judgment task C has a coupon of 30 yuan. As Figure 4 shown, assume that the parallel processing sub-result of logical judgment task A is 80 (the drug price after discount is 20 yuan), the parallel processing sub-result of logical judgment task B is 90 (the drug price after discount is 10 yuan), and the parallel processing sub-result of logical judgment task C is 70 (the drug price after discount is 30 yuan).

[0059] Since the balances of the target virtual accounts in the database are all found to be 100 ($old_money = 100) by the above three deduction logics, at this time, the three logic judgment tasks simultaneously perform modification operations on the database balance. Then, the parallel processing sub-result of the last executed logic judgment task will be the final result stored in the database.

[0060] Suppose that logic judgment task C generates the parallel processing sub-result latest. Then, the balance of the target virtual account in the database is 70 yuan finally.

[0061] However, in the actual business scenario, after the above three deduction processes are executed, the balance of the patient should be 40 yuan (100 - 20 - 10 - 30 = 40). Therefore, the parallel execution of the above logic judgment tasks A, B, and C will lead to data writing conflict phenomena.

[0062] According to the parallel processing method of the present disclosure embodiment, as Figure 4 shown, the data consistency under concurrent request conditions can be ensured through the following execution steps.

[0063] Step S402, the first parallel thread executes logic judgment task A, queries the value of the target virtual account in the database (i.e., the first value: old_money = 100). After executing logic judgment task A, the parallel processing sub-result is calculated (new_money = 100 - 20 = 80). After logic judgment task A, compare whether the value of the target virtual account in the database (i.e., the second value) is equal to the first value 100. If the judgment result is consistent, then perform the modification.

[0064] Step S404, the second parallel thread executes logic judgment task B, queries the balance of the target virtual account in the database (i.e., the first value: old_money = 100). After executing logic judgment task B, the parallel processing sub-result is calculated (new_money = 100 - 10 = 90). After executing logic judgment task B, compare whether the value of the target virtual account in the database (i.e., the second value) is equal to the first value 100. It is found that the balance in the database has been modified to 80 by step S402 at this time, so the update is not executed, and a failure is returned, and the retry is executed.

[0065] Step S406, the third parallel thread executes logic judgment task C, queries the balance of the target virtual account in the database (i.e., the first value: old_money = 100). After executing logic judgment task C, the parallel processing sub-result is calculated (new_money = 100 - 30 = 70). After executing logic judgment task C, compare whether the value of the target virtual account in the database (i.e., the second value) is equal to the first value 100. It is found that the balance in the database has been modified to 80 by the first step at this time, so the update is not executed, and a failure is returned, and the retry is executed.

[0066] Step S408: When the second parallel thread retries the logical judgment task B, it rereads the balance of the target virtual account in the database (i.e., the first value: old_money = 80), executes the logical judgment task B, and calculates the parallel processing sub-result (new_money = 80 - 10 = 70). After executing the logical judgment task B, compare whether the value of the target virtual account in the database (i.e., the second value) is equal to the first value 80. If the judgment result is consistent, then execute the modification.

[0067] Step S410: When the third parallel thread retries the logical judgment task C, it rereads the balance of the target virtual account in the database (i.e., the first value: old_money = 70), executes the logical judgment task C, and calculates the parallel processing sub-result (new_money = 70 - 30 = 40). After executing the logical judgment task C, compare whether the value of the target virtual account in the database (i.e., the second value) is equal to the first value 70. If the judgment result is consistent, then execute the modification.

[0068] After the above steps, the final value of the target virtual account is 40, which can ensure the consistency of data in the database under high concurrency. In this embodiment, only by comparing the first value and the second value, the phenomenon of concurrent execution result conflicts can be avoided, and the rapid delivery of the ToB business construction can be satisfied.

[0069] It should be clearly understood that the present disclosure describes how to form and use specific examples, but the principles of the present disclosure are not limited to any details of these examples.
