Abstract
Description
Technical Field
[0001] This invention relates to the field of computer technology, and in particular to a method and apparatus for distributing virtual resources. Background Technology
[0002] In current e-commerce scenarios, users are often rewarded and rewarded with virtual resources, such as points awarded after a user places an order. The real-time requirements for this virtual resource distribution are not high, and asynchronous distribution is generally used in practice. The main methods currently employed include: using message queues or API calls to perform virtual resource calculation, distribution, and accounting. The disadvantages of this approach are: First, using a single program to perform the calculation, distribution, and accounting of indivisible virtual resources means that if an error occurs, the entire process must be re-executed, leading to low efficiency. Second, virtual resource distribution between different orders can only be performed serially, limiting system throughput. Third, when an order's calculation fails, it is immediately archived, which can easily lead to a backlog of erroneous data, triggering alarms and impacting system performance.

[0017] The present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the virtual resource distribution method provided by the present invention.
[0018] According to the technical solution of the present invention, the embodiments described above have the following advantages or beneficial effects:
[0019] First, information on completed orders is stored in a pre-created database table. Then, based on multiple pre-defined worker nodes, this information is processed to determine the corresponding virtual resources and distribute them to the users indicated by the completed orders. Each worker node corresponds one-to-one with multiple tasks executed in a preset order during the virtual resource distribution process. Each worker node deploys multiple instances to process multiple completed orders in parallel. Multiple worker nodes process the same completed order sequentially. The instance of the earlier node among any two adjacent worker nodes stores intermediate processing results in a database table, allowing subsequent nodes to read and process them. This allows each node to deploy multiple instances to process multiple orders in parallel, thereby improving system throughput. When processing the same order, each worker node completes its task's processing steps and stores the data in the database sequentially according to a preset order. Subsequent worker nodes read data from the database and process it accordingly. This divides the virtual resource distribution process into multiple independently executed fine-grained tasks, facilitating multiple retries for the current specific task and improving virtual resource distribution efficiency.
[0020] The further effects of the aforementioned unconventional alternative methods will be explained below in conjunction with specific implementation methods. Attached Figure Description

[0028] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0029] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.
[0030] Figure 1 This is a schematic diagram of the main steps of the virtual resource distribution method in an embodiment of the present invention.
[0031] like Figure 1 As shown, the virtual resource allocation method of this embodiment of the invention can be executed by a computer system or server for performing virtual resource allocation (hereinafter referred to as the virtual resource allocation system), and can be specifically executed according to the following steps:
[0032] Step S101: In response to order completion, information on multiple completed orders is stored in a pre-created first database table. In this step, after an order is completed, the order system can send an order completion message to the virtual resource distribution system via a message queue. The virtual resource distribution system can then store the information of the completed orders in a pre-created database table. This information may include order details such as order identifier, user identifier, product identifier, user level, product category, and order amount. The virtual resources mentioned above refer to any resource presented on computing devices such as computers and smart terminals, such as points or coupons. Points will be used as an example below.
[0033] Step S102: Based on multiple pre-set working nodes, process the information of completed orders to determine the virtual resources corresponding to the completed orders; distribute the virtual resources to the users indicated by the completed orders.
[0034] In this step, the virtual resource distribution system processes information related to completed orders based on multiple pre-defined work nodes. It then calculates the virtual resources corresponding to the completed orders according to a pre-defined virtual resource distribution strategy and distributes the virtual resources to the users indicated by the completed orders. These work nodes refer to pre-written programs or services that perform periodic checks on database tables. Specifically, these multiple work nodes correspond one-to-one with multiple tasks executed in a pre-defined order within the virtual resource distribution process. For example, these tasks may include a sequential sequence: a resource calculation task, a resource distribution task, a distribution result recording task, and a downstream system notification task. The resource calculation task calculates the virtual resource data corresponding to the order (e.g., virtual resource type, quantity, distribution method, etc.), the resource distribution task distributes the virtual resources to the user, the distribution result recording task records the distribution result, and the downstream system notification task notifies the downstream system to perform subsequent processing after the recording is completed.
[0035] Accordingly, the above multiple working nodes can include: a computing node corresponding to the resource computing task, a distribution node corresponding to the resource distribution task, a recording node corresponding to the distribution result recording task, and a notification node corresponding to the downstream system notification task. Each working node can be deployed with multiple instances to process multiple completed orders in parallel, thereby improving system throughput. It can be understood that in practical applications, the number of instances can be deployed according to the workload of each working node. Furthermore, the above multiple working nodes can process the same completed order serially in the above order. The order of the working nodes is: computing node, distribution node, recording node, notification node, with the computing node preceding the distribution node, the distribution node preceding the recording node, and the recording node preceding the notification node.
[0036] Instances of the earlier node among any two adjacent working nodes store intermediate processing results in a database table, allowing instances of the later node to read and process them. It can be understood that for adjacent nodes (calculation node and issuing node), the calculation node is the earlier node, and the issuing node is the later node; for adjacent nodes (issuing node and recording node), the issuing node is the earlier node, and the recording node is the later node; for adjacent nodes (recording node and notification node), the recording node is the earlier node, and the notification node is the later node. As a preferred solution, the initial state of the records containing information about completed orders and intermediate processing results in the database table is "pending processing."
[0037] Based on the above settings, each worker node can process multiple orders in parallel using multiple instances configured separately. However, for the same order, processing must be sequential. That is, after the previous task node performs its processing, it stores the result in the database. The next task node then reads the result from the database table and performs its own processing, until the entire virtual resource delivery process is complete. These steps improve the data processing throughput of the virtual resource delivery system. Furthermore, dividing the virtual resource delivery process into multiple independently executed fine-grained tasks facilitates multiple retries for the current specific task, thereby improving the efficiency of virtual resource delivery.
[0038] Figure 2 This is a schematic diagram of the system structure of the virtual resource allocation method in an embodiment of the present invention. See [link / reference]. Figure 2 The virtual resource allocation system interacts with the order system and downstream systems through message queues. Internally, the virtual resource allocation system includes compute nodes, allocation nodes, recording nodes, and notification nodes, each with multiple instances deployed.
[0039] Figure 3 This is a schematic diagram illustrating the specific execution of the virtual resource allocation method in this embodiment of the invention. See [link / reference]. Figure 3 The first step is for the virtual resource allocation system to consume order completion messages from the message queue, store the information of completed orders in the first database table, and record the corresponding records in the first database table as "pending processing".
[0040] In the second step, after the virtual resource allocation system detects new data in the first database table based on the instance of the computing node, it reads the information of the target completed order with a status of "pending processing" from the first database table and updates the status of the corresponding record to "processing". Through this status update operation, a distributed lock mechanism can prevent multiple instances from reading and processing the same record, thus ensuring data consistency. Next, the virtual resource allocation system calculates the information of the target completed order based on the instance of the computing node to obtain the virtual resource calculation result as an intermediate processing result. For example, the virtual resource calculation result may include: order identifier, user identifier, product identifier, virtual resource type, virtual resource quantity, virtual resource allocation method, etc. Afterwards, the virtual resource allocation system writes the virtual resource calculation result to the second database table based on the instance of the computing node; after successful writing, the corresponding record of this information in the first database table is deleted; wherein, the write operation and the deletion operation are within the same database transaction. Through the above settings, atomic operations can be used to avoid data errors or loss.
[0041] Third, after detecting new data in the second database table based on the instance of the distribution node, the virtual resource distribution system reads the virtual resource calculation results of the target completed orders with a status of "pending processing" from the second database table, updates the status of the corresponding records to "processing," and performs resource distribution to the users indicated by the target completed orders according to the virtual resource calculation results. The virtual resource distribution results, as intermediate processing results, are written to the third database table. For example, the virtual resource distribution results may include: order identifier, user identifier, product identifier, whether the virtual resource distribution was successful, the type of virtual resource distributed, the quantity of virtual resources distributed, and the virtual resource distribution method. After successful writing, the virtual resource distribution system deletes the corresponding record of the virtual resource calculation results in the second database table based on the instance of the distribution node; the write operation and the delete operation are within the same database transaction.
[0042] In the fourth step, after the virtual resource allocation system detects new data in the third database table based on the instance of the record node, it reads the virtual resource allocation results of completed target orders with a status of "pending processing" from the third database table, updates the status of the corresponding records to "processing," and records the transactions based on the virtual resource allocation results. The record results, as intermediate processing results, are then written to the fourth database table. These record results may include: order identifier, user identifier, product identifier, whether the accounting was successful, and account details. After successful writing, the virtual resource allocation system deletes the corresponding record of the virtual resource allocation result in the third database table based on the instance of the record node; this write operation and the deletion operation are within the same database transaction.
[0043] Fifth, after the virtual resource allocation system detects the new data in the fourth database table based on the instance of the notification node, it reads the record results of the target completed order with the status of "pending processing" from the fourth database table, updates the status of the corresponding record to "processing", and sends a notification to the downstream system based on the record results, for example, generating a message notification and sending it to the message queue for the downstream system to consume. After the notification is completed, the virtual resource allocation system deletes the corresponding record in the fourth database table based on the instance of the notification node.
[0044] As a preferred solution, the virtual resource allocation system can detect records in any database table that have remained in a "processing" state for a first preset time (e.g., 2 hours) based on pre-set monitoring nodes. These monitoring nodes refer to pre-written monitoring programs or services, and the database tables include the first, second, third, and fourth database tables. If such a record is detected, it indicates that the record has been unable to complete calculations successfully for an extended period. The virtual resource allocation system can then retry the detected record and the task containing that record based on the monitoring nodes—that is, retry the current task without starting from the beginning. The retry count for that record is set to 1, and the retry time is obtained.
[0045] If the retry time for any record reaches the second preset duration and the current number of retries has not reached the preset maximum number of retries, the virtual resource allocation system can execute the next retry based on the monitoring node, incrementing the retry count for that record by 1. If the retry count for any record reaches the maximum number of retries, the virtual resource allocation system can issue an alarm message based on the monitoring node. Through these settings, most computational problems can be solved through multiple automatic retries, with alarms only issued if multiple retries still fail. This avoids the frequent alarms caused by large amounts of data archiving and backlog in existing technologies, thus improving system performance.
[0046] In the technical solution of this invention embodiment, the virtual resource allocation process is divided into multiple independent tasks executed in a preset order: a resource calculation task, a resource allocation task, an allocation result recording task, and a downstream system notification task. Corresponding worker nodes are configured, namely, a calculation node for the resource calculation task, an allocation node for the resource allocation task, a recording node for the allocation result recording task, and a notification node for the downstream system notification task. Each node can deploy multiple instances to process multiple orders in parallel, thereby improving system throughput. When processing the same order, each worker node completes the processing steps of its task and writes the data to the database sequentially in a preset order. The next worker node reads data from the database and processes it accordingly. This divides the virtual resource allocation process into multiple fine-grained tasks that are executed independently, which helps to perform multiple retries for the current specific task, thereby improving the efficiency of virtual resource allocation. Each worker node instance updates its status after reading the record in the database table, thereby avoiding data errors caused by multiple instances reading the same record. Furthermore, after each worker node instance executes its task and writes the data to the database table, it deletes the previously read record. The above write and delete operations are within the same database transaction, thereby ensuring data consistency. In this embodiment of the invention, the processing time of each database table is detected by monitoring nodes. When the processing time reaches a threshold, a retry for the current task is automatically triggered, and an alarm is only triggered when the number of retries reaches the threshold. This avoids frequent alarms caused by a large amount of data archiving and backlog, thereby improving system performance.
[0047] It should be noted that the technical solutions of this invention, including the collection, updating, analysis, processing, use, transmission, and storage of user personal information, all comply with relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. Necessary measures are taken to prevent unauthorized access to user personal information data and to safeguard user personal information security, network security, and national security.
[0048] For the foregoing method embodiments, they are described as a series of actions for ease of description. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, and some steps may actually be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential for implementing the present invention.
[0049] To facilitate better implementation of the above-described solutions of the embodiments of the present invention, related apparatus for implementing the above-described solutions is also provided below.
[0050] Please see Figure 4 As shown, the virtual resource distribution device 400 provided in this embodiment of the invention may include: an order storage unit 401 and a virtual resource processing unit 402.
[0051] The order storage unit 401 is used to store information of multiple completed orders in a pre-created first database table in response to order completion; the virtual resource processing unit 402 is used to process the information of the completed orders based on multiple preset working nodes to determine the virtual resources corresponding to the completed orders; and to distribute the virtual resources to the user indicated by the completed order; wherein, the multiple working nodes correspond one-to-one with multiple tasks included in the virtual resource distribution process and executed in a preset order, and each working node deploys multiple instances to process multiple completed orders in parallel; the multiple working nodes process the same completed order serially in the preset order; the instance of the earlier node among any two adjacent working nodes stores the intermediate processing results in the database table so that the instance of the later node can read and process them.
[0052] In this embodiment of the invention, the plurality of tasks include: a resource computing task, a resource allocation task, an allocation result recording task, and a downstream system notification task. The plurality of working nodes include: a computing node corresponding to the resource computing task, an allocation node corresponding to the resource allocation task, a recording node corresponding to the allocation result recording task, and a notification node corresponding to the downstream system notification task.
[0053] In a specific application, the initial state of the records containing the information of the completed orders and the intermediate processing results in the database table is "pending processing"; and the virtual resource processing unit 402 can be further used to: read the information of the target completed orders with the state "pending processing" from the first database table based on the instance of the computing node, and update the state of the corresponding records to "processing"; calculate the information of the target completed orders to obtain the virtual resource calculation result as the intermediate processing result, and write the virtual resource calculation result into the second database table; after successful writing, delete the corresponding record of the information in the first database table; wherein, the writing operation and the deletion operation are in the same database transaction.
[0054] In practical applications, the virtual resource processing unit 402 can be further used to: read the virtual resource calculation results of the target completed order with a status of "pending processing" from the second database table based on the instance of the distribution node, and update the status of the corresponding record to "processing"; perform resource distribution to the user indicated by the target completed order according to the virtual resource calculation results, and write the virtual resource distribution result as the intermediate processing result into the third database table; after successful writing, delete the corresponding record of the virtual resource calculation result in the second database table; wherein, the writing operation and the deletion operation are in the same database transaction.
[0055] As a preferred embodiment, the virtual resource processing unit 402 can be further configured to: read the virtual resource allocation results of the target completed order with a status of "pending processing" from the third database table based on the instance of the record node, and update the status of the corresponding record to "processing"; record the accounts according to the virtual resource allocation results, and write the record results as the intermediate processing results into the fourth database table; after successful writing, delete the corresponding record of the virtual resource allocation results in the third database table; wherein the writing operation and the deletion operation are in the same database transaction.
[0056] Preferably, the virtual resource processing unit 402 can be further configured to: read the record results of the target completed order with a status of "pending processing" from the fourth database table based on the instance of the notification node, update the status of the corresponding record to "processing"; send a notification to the downstream system according to the record results, and delete the corresponding record of the record results in the fourth database table after the notification is completed.
[0057] Furthermore, in this embodiment of the invention, the device 400 may further include a monitoring unit, configured to: detect records in any database table that have maintained a "processing" state for a first preset duration based on preset monitoring nodes; perform retries for the detected records and the tasks to which the records belong; set the retry count of the record to 1 and obtain the retry time; if the retry time of any record reaches a second preset duration and the current retry count has not reached the preset maximum retry count, perform the next retry and increment the retry count of the record by 1; and if the retry count of any record reaches the maximum retry count, issue an alarm message.
[0058] According to the technical solution of this invention, the virtual resource allocation process is divided into multiple independent tasks executed in a preset order: a resource calculation task, a resource allocation task, an allocation result recording task, and a downstream system notification task. Corresponding working nodes are configured, namely, a calculation node for the resource calculation task, an allocation node for the resource allocation task, a recording node for the allocation result recording task, and a notification node for the downstream system notification task. Each node can deploy multiple instances to process multiple orders in parallel, thereby improving system throughput. When processing the same order, each working node completes the processing steps of its task and writes the data to the database sequentially in a preset order. The next working node reads data from the database and processes it accordingly. This divides the virtual resource allocation process into multiple fine-grained tasks that are executed independently, which helps to perform multiple retries for the current specific task, thereby improving the efficiency of virtual resource allocation. Each working node instance updates its status after reading the record in the database table, thereby avoiding data errors caused by multiple instances reading the same record. Furthermore, after each working node instance executes its task and writes the data to the database table, it deletes the previously read record. The above write and delete operations are within the same database transaction, thereby ensuring data consistency. In this embodiment of the invention, the processing time of each database table is detected by monitoring nodes. When the processing time reaches a threshold, a retry for the current task is automatically triggered, and an alarm is only triggered when the number of retries reaches the threshold. This avoids frequent alarms caused by a large amount of data archiving and backlog, thereby improving system performance.

[0073] The units described in the embodiments of the present invention can be implemented in software or hardware. The described units can also be housed in a processor; for example, a processor can be described as including an order storage unit and a virtual resource processing unit. The names of these units do not necessarily limit the specific unit; for example, the order storage unit can also be described as "a unit that provides completed order information to the virtual resource processing unit."
[0074] In another aspect, the present invention also provides a computer-readable medium, which may be included in the device described in the above embodiments; or it may exist independently and not assembled into the device. The computer-readable medium carries one or more programs, which, when executed by the device, cause the device to perform the following steps: in response to order completion, storing information of multiple completed orders in a pre-created first database table; processing the information of the completed orders based on a pre-set plurality of working nodes to determine the virtual resources corresponding to the completed orders; and distributing the virtual resources to the user indicated by the completed order.
[0075] In the technical solution of this invention embodiment, the virtual resource allocation process is divided into multiple independent tasks executed in a preset order: a resource calculation task, a resource allocation task, an allocation result recording task, and a downstream system notification task. Corresponding worker nodes are configured, namely, a calculation node for the resource calculation task, an allocation node for the resource allocation task, a recording node for the allocation result recording task, and a notification node for the downstream system notification task. Each node can deploy multiple instances to process multiple orders in parallel, thereby improving system throughput. When processing the same order, each worker node completes the processing steps of its task and writes the data to the database sequentially in a preset order. The next worker node reads data from the database and processes it accordingly. This divides the virtual resource allocation process into multiple fine-grained tasks that are executed independently, which helps to perform multiple retries for the current specific task, thereby improving the efficiency of virtual resource allocation. Each worker node instance updates its status after reading the record in the database table, thereby avoiding data errors caused by multiple instances reading the same record. Furthermore, after each worker node instance executes its task and writes the data to the database table, it deletes the previously read record. The above write and delete operations are within the same database transaction, thereby ensuring data consistency. In this embodiment of the invention, the processing time of each database table is detected by monitoring nodes. When the processing time reaches a threshold, a retry for the current task is automatically triggered, and an alarm is only triggered when the number of retries reaches the threshold. This avoids frequent alarms caused by a large amount of data archiving and backlog, thereby improving system performance.
[0076] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
