[0019] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and 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 this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0020] In a distributed system environment, a business processing unit typically needs to combine requests to multiple services. This is especially true in systems with a large number of microservices, where the number of combined service requests can reach dozens. Furthermore, complex, step-by-step business logic is often implemented through a large number of operations. To ensure the normal operation of a distributed system, the consistency of these requests and operations must be guaranteed. The mechanism for ensuring the consistency of these requests and operations is called distributed transactions.

[0021] In related technologies, there are various distributed transaction processing schemes, such as XA (a two-phase commit protocol defined by the X / Open DTP organization) and TCC (Try, Confirm, Cancel), which can process transactions in a distributed manner. However, these technologies introduce a strong coupling problem between the business side and the transaction coordinator during implementation. This causes the transaction coordinator's code to intrude into the business logic, requiring users to perform simultaneous maintenance on the transaction coordinator when operating the business, resulting in high operational costs for the business.

[0022] To address the aforementioned technical problems, embodiments of this disclosure provide a distributed transaction processing method, as follows: Figure 1 As shown, it includes:

[0023] S101, obtain the current action state of the business state machine as the first action state.

[0024] S102, call the first business operation interface corresponding to the first action state of the business state machine, so that the business side executes the operation corresponding to the first business operation interface.

[0025] By using this embodiment, the transaction coordinator can call the business operation interface corresponding to different states based on the first action state of the business state machine, so that each business end can perform the corresponding operation according to the business operation interface. It can be seen that the transaction coordinator of this disclosure only calls the business operation interface according to the state of the business state machine, and each business end only executes the corresponding operation according to the business operation interface. It is not necessary to apply the operation steps corresponding to the business to different businesses. The transaction coordinator interacts with the business through the interface. The transaction coordinator only needs to obtain the state of the business and call the operation interface corresponding to the state for the business. This decouples the transaction coordinator from each business, reduces the intrusion of the transaction coordinator into the business end, and reduces the operation and maintenance cost of the business.

[0026] In S101, the business state machine is a state machine that presents the business processing status. The actions of each node on the business state machine can be predefined according to different business content. For example, taking an online shopping application scenario, there is a user payment order business. Suppose that this business process includes the step of modifying the order status. Then, in the business state machine corresponding to this business, the action corresponding to a node can be defined as modifying the order status, and whether the modification of the order status was successful can be defined as the state corresponding to that node. It can be understood that if the action of modifying the order status in a business operation fails, the current action state (first action state) of the corresponding node in the business state machine for that business is "modification of order status failed."

[0027] In this embodiment, the action state of each node of the business state machine corresponding to the business can be obtained, and the action state of each node can be used as the first action state of the business state machine.

[0028] In S102, after determining the first action state of the business state machine, the corresponding business operation interface can be called based on the first action state of each node. For example, taking the user payment order business in an online shopping application scenario, if the business side fails to execute the step "Modify Order Status," the business state machine displays the corresponding first action state. It is understandable that, because the step "Modify Order Status" failed, to ensure business consistency, all other steps in the user payment order business of this online shopping application scenario should be rolled back to the unstarted state. Therefore, based on the first action state of the business state machine, the transaction coordinator should call the compensation business operation interface corresponding to this first action state to allow the business side to restore to the starting state and re-perform the operation.

[0029] For example, if all steps in the user payment order business in an online shopping application scenario are executed successfully, and the business state machine displays the first action state, then the corresponding business operation interface called by the transaction coordinator for this first action state should be the verification business operation interface, so that the business side can verify each completed step.

[0030] During implementation, the execution steps and states of the business process frequently change. For example, taking the online shopping application scenario mentioned above, if another user buys the same item after one user has purchased it, the business side needs to process the payment order for that user, and the state machine's action state should change accordingly. Based on this, this disclosure also provides a distributed transaction processing method, such as... Figure 2 The above includes:

[0031] S201, Obtain the current action state of the business state machine as the first action state.

[0032] This step is the same as S101 above, and you can refer to the relevant description of S101 above, so it will not be repeated here.

[0033] S202, call the first business operation interface corresponding to the first action state of the business state machine, so that the business side executes the operation corresponding to the first business operation interface.

[0034] This step is the same as S102 above, and you can refer to the relevant description of S102 above, so it will not be repeated here.

[0035] S203, obtain the execution results of each preset execution step of the business on the business side.

[0036] For any given business operation, the execution steps can vary depending on the specific content. Technical personnel can pre-set these execution steps for different business operations. For example, in an online shopping scenario, if another user purchases the same item as a previous user, the business logic needs to process this newly generated payment order. The pre-set execution steps for this payment order might be modifying the order status, deducting inventory, and creating a sales order. The results of these pre-set steps could be whether the order status modification was successful, whether the inventory deduction was correct, and whether the sales order creation was correct, respectively. It's understandable that the business logic will obtain the results after executing each pre-set step; therefore, the business logic can send the execution results corresponding to each pre-set step to the transaction coordinator.

[0037] S204. Based on the execution result of the business, update the current action state of the business state machine to obtain the second action state of the business state machine.

[0038] After obtaining the execution results of each preset execution step of the business process, the transaction coordinator can update the current action state of the business state machine based on the execution results. For example, if the execution results of each preset execution step of the business process are successful modification of order status, correct deduction of inventory, and correct creation of sales delivery order, then the business state machine needs to update the action state of the corresponding node of each step according to the execution results, thereby obtaining the second action state of the business state machine.

[0039] S205, call the second business operation interface corresponding to the second action state of the business state machine, so that the business side executes the operation corresponding to the second business operation interface.

[0040] This step is similar to S102 above, and you can refer to the relevant description of S102 above, so it will not be repeated here.

[0041] By using this embodiment, the action state of the business state machine can be updated in real time according to the processing status of different business operations, and then the business operation interface corresponding to different action states can be called in real time, so that each business can be further processed as soon as possible, thereby improving the timeliness of distributed transaction processing.

[0042] In one possible embodiment, various problems such as network anomalies or server anomalies may occur during the actual implementation of the business, causing issues such as duplicate reporting, out-of-order reporting, and lost reporting of business requests on the business side. Furthermore, this can lead to the transaction coordinator repeatedly, out of order, or missingly calling the business operation interface based on these abnormal business requests, resulting in the business being unable to process normally. Based on this, this application also provides a distributed business processing method, such as... Figure 3 As shown, it includes:

[0043] S301, obtain the current action state of the business state machine as the first action state.

[0044] This step is the same as S101 above, and you can refer to the relevant description of S101 above, so it will not be repeated here.

[0045] S302, call the first business operation interface corresponding to the first action state of the business state machine, so that the business side executes the operation corresponding to the first business operation interface.

[0046] This step is the same as S102 above, and you can refer to the relevant description of S102 above, so it will not be repeated here.

[0047] S303, update the state of the transaction state machine according to the result of the corresponding operation performed by the business end, and obtain the third action state of the transaction state machine.

[0048] A transaction state machine is a state machine that presents the transaction processing status of the business side. The transaction state machine can preset different actions at corresponding nodes based on different business operation interfaces. For example, at a certain node, the preset action for modifying the order status might be compensation or verification, and correspondingly, the action status at that node might be verification successful or verification failed. Therefore, the transaction state machine can update its action status based on the operation results of the corresponding business operation interface executed by the business side.

[0049] For example, taking the user payment order business in the aforementioned online shopping application scenario as an example, if all steps in this business are executed successfully, the business side needs to perform operations according to the verification business operation interface corresponding to the first action state called by the transaction coordinator, verify the execution results of each execution step, and determine whether the verification is successful. Thus, the transaction coordinator can obtain the operation results of the business side's execution of the business operation interface from the business side. If, at this time, only the step of deducting inventory fails verification, while all other execution steps are verified successfully, the transaction state machine can update the action state of each node according to the operation results. That is, update the verification of modifying the order status to verification successful, update the verification of deducting inventory to verification failed, and update the verification of creating a sales delivery order to verification successful, thereby obtaining the third action state of the transaction state machine.

[0050] S304: Receives a business request from the business side and obtains the context corresponding to the business request.

[0051] While the transaction regulator invokes business operation interfaces based on the action state of the business state machine, the business itself also sends business requests to the transaction regulator based on its own business processing status, enabling the transaction regulator to coordinate the next step of the business processing. It can be understood that the business request contains content indicating the business being requested, such as business information indicating whether it's a user order payment or user refund, etc. The business request also contains content indicating the business operation interface it requests; for example, if a step in the business fails and the business requests compensation, the interface information indicating the compensation request will also be included in the business request. The context corresponding to the business request can be relevant information needed to process the business request, or the background when the business sends the business request, such as the processing progress of the business.

[0052] S305, determine whether the business request is an abnormal business request based on the context and the third action status.

[0053] The context of the business request can be obtained, and the third action state of the transaction state machine can determine the operation result of the business side according to the business operation interface. Based on this, the transaction coordinator can determine the processing progress of a business, the operation according to the business operation interface, and the operation result based on the context and the third action state. Based on the business state determined by the transaction coordinator, it can determine whether the received business request is an abnormal business request. For example, if a business request requests a compensation business operation interface, and the transaction coordinator determines from the current action state of the corresponding transaction state machine that the business has already been compensated according to the compensation business operation interface and the compensation was successful, then the business request should be judged as a duplicate request, i.e., an abnormal business request. For example, if a business request requests a validation business operation interface, and the latest node status displayed on the transaction state machine corresponding to that business is "compensation successful," it can be determined from the context of the business request that when the business request was issued, the validation operation had already been requested for the content contained in the business request. If the status of the previous node of the transaction state machine is then checked, it shows that the validation action corresponding to the content contained in the business was successful. It can be understood that the business request has been processed. At this point, the transaction coordinator can determine that the business request is an out-of-order request, i.e., an abnormal business request.

[0054] S306, if so, refuse to perform the operation based on the business request.

[0055] If the transaction coordinator determines that the received business request is an abnormal business request, the transaction coordinator will refuse to call the requested business operation interface for the business, and will not update the action state of the transaction state machine based on the operation result.

[0056] S307, if not, call the business operation interface requested by the business request, so that the business side can perform the corresponding operation according to the business operation interface and update the third action state of the transaction state machine.

[0057] By using this embodiment, the transaction coordinator can avoid calling the business operation interface for abnormal business requests caused by network or server anomalies, filtering duplicate requests, correcting out-of-order requests, and filling in lost reporting issues that could lead to abnormal transaction status and business processing, thereby improving the fault tolerance of distributed transaction processing.

[0058] In one possible embodiment, the business request is sent from the business side to the transaction coordinator through an idempotent transaction interface.

[0059] It is understandable that a transaction interface is the interface through which a business sends a business request to the transaction coordinator, and an idempotent transaction interface can ensure that one or more requests for the same business request yield consistent results.

[0060] By selecting this embodiment, the idempotent nature of the transaction interface can be used to avoid abnormal business requests that could lead to abnormal business processing and transaction status, thereby further improving the fault tolerance of distributed transaction processing.

[0061] In distributed transaction processing, although the business logic is not sensitive to latency, the transaction coordinator needs to ensure timeliness and avoid transaction blocking. Based on this, this disclosure also provides a distributed transaction processing method, such as... Figure 4 As shown, it includes:

[0062] S401, classify multiple business requests into different types of business requests based on business type and transaction type.

[0063] The business type indicates the type of business that generates the business request, and the transaction type indicates the type of transaction requested by the business request. In actual business processing, the transaction coordinator often receives multiple business requests simultaneously. As mentioned earlier, each business request contains the specific content of the business (i.e., the business type) and the business operation interface requested by that business (i.e., the transaction type). Based on this, multiple business requests can be divided into different types of business requests for subsequent processing.

[0064] S402 arranges different types of business requests into the corresponding request queues.

[0065] The request queue is a queue divided according to the type of business request. After the request queue is divided according to the business request, each business request can be placed into the corresponding request queue according to its type.

[0066] S403 delivers multiple service requests to the same data center according to their corresponding request queues, and receives service requests from multiple request queues.

[0067] After queuing business requests into corresponding queues based on their types, the requests in each queue need to be sent to the data center for processing. Specifically, multiple business requests can be sent to the same data center for processing. At the same time, multiple business requests can be sent to the same data center according to their request queues, allowing the transaction coordinator to receive and process business requests in a more refined manner based on the different request queues, i.e., the different types of business requests. Sending multiple business requests to the same data center can also further reduce the processing latency of business requests.

[0068] In one possible implementation, higher-priority business requests can be queued into the same request queue, allowing the transaction coordinator to prioritize higher-priority business requests based on the queue.

[0069] By selecting this embodiment, business requests are finely broken down in terms of business and transaction dimensions, and the business requests are delivered to the same data center. The transaction coordinator then receives the business requests, which improves the efficiency of the transaction coordinator in receiving business requests and reduces the latency of business request processing.

[0070] In one possible embodiment, after determining that the business request is not an abnormal business request, it needs to be processed according to the business request. A single business request often triggers multiple actions. For example, if multiple preset execution steps of a certain business require compensation, then these multiple preset execution steps need to be compensated according to the compensation business operation interface. Therefore, a single business request sent by this business may include requests to multiple compensation business operation interfaces. When the transaction coordinator faces the simultaneous need to call multiple business operation interfaces, it may encounter difficulties in processing them in a timely manner. Based on this, this disclosure also provides a distributed transaction processing method, such as... Figure 5 As shown, it includes:

[0071] S501, obtain the current action state of the business state machine as the first action state.

[0072] This step is the same as S101 above, and you can refer to the relevant description of S101 above, so it will not be repeated here.

[0073] S502, call the first business operation interface corresponding to the first action state, so that the business side executes the corresponding operation by executing the first business operation interface.

[0074] This step is the same as S102 above, and you can refer to the relevant description of S102 above, so it will not be repeated here.

[0075] S503, update the state of the transaction state machine according to the result of the corresponding operation performed by the business end, and obtain the third action state of the transaction state machine.

[0076] This step is the same as S303 above, and you can refer to the relevant description of S303 above, so it will not be repeated here.

[0077] S504 receives business requests from the business side and obtains the context corresponding to the business requests.

[0078] This step is the same as S304 above, and you can refer to the relevant description of S304 above, so it will not be repeated here.

[0079] S505 determines whether a business request is an abnormal business request based on the context and the third action status.

[0080] This step is the same as S305 above, and you can refer to the relevant description of S305 above, so it will not be repeated here.

[0081] S506, if not, divide the business request into multiple first business messages based on the content contained in the business request.

[0082] At this point, it has been determined that the business request is not an abnormal business request. The business request can then be broken down according to its content. Taking the user payment order business in the online shopping application scenario as an example, if the execution of modifying the order status fails, the business side may send a business request, which may include operations such as compensation for modifying the order status, compensation for deducting inventory, and compensation for creating a sales order. In this case, the business request can be divided into the first business message of compensation for modifying the order status, the first business message of compensation for deducting inventory, and the first business message of compensation for creating a sales order according to its content.

[0083] S507 concurrently calls the business operation interfaces corresponding to multiple first business messages.

[0084] After splitting a business request into multiple first business messages, the transaction coordinator can concurrently call the business operation interface in sequence according to the specific content of each first business message to process the business request.

[0085] By using this embodiment, a business request can be split into multiple business messages, and the business operation interface can be called for the business messages in sequence according to their content. This allows multiple first business messages in a business request to be processed concurrently, improving the timeliness of business request processing.

[0086] The collection, storage, use, processing, transmission, provision, and disclosure of user personal information involved in the technical solution disclosed herein comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0098] The business request processing module is used to, if not, call the business operation interface requested by the business request, so that the business terminal performs the corresponding operation according to the business operation interface and updates the third action state of the transaction state machine.

[0099] In one possible embodiment, the business request is sent from the business side to the transaction coordinator through an idempotent transaction interface.

[0100] In one possible embodiment, the service request determination module further includes:

[0105] A business message splitting unit is used to divide the business request into multiple first business messages according to the content contained in the business request, if not otherwise.

[0106] The business message processing unit is used to concurrently call multiple business operation interfaces corresponding to the first business message.
