Description

Technical Field

[0001] The present invention relates to the field of big data technology, and in particular to a transaction processing method, device, electronic device and computer-readable medium. Background Art

[0002] In a distributed banking system, an external reversal is a reversal initiated by the caller from outside the system. It mostly occurs in situations such as transferring the wrong account or sending the wrong transaction. It requires the withdrawal of the previously issued positive transaction in order to roll back the positive transaction to the state before execution. When processing an external reversal, if the current transaction is being executed, the system will give priority to protecting the positive transaction and directly return the external reversal with an error. This practice is highly dependent on the subsequent re-initiation of external reversals. If the subsequent reversal is no longer initiated, the final consistency of the transaction flow record will be inconsistent. The existing reversal method is highly dependent on the re-initiation of external reversals. If there is no subsequent initiation, the transaction will be lost, and the final consistency of the transaction flow will be inconsistent, as well as unnecessary errors in the transaction process, which requires subsequent manual processing and manual reversal, wasting resources and manpower.

[0048] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0049] The technical terms involved in the embodiments of the present invention are explained below.

[0050] Positive transaction: refers to a positive transaction logic, which is a type of transaction developed to achieve a certain business effect.

[0051] Reversal transaction: a type of transaction that has reverse logic to a positive transaction. It is a reverse transaction logic developed to eliminate the business effect achieved by a positive transaction.

[0052] Outbound call reversal: also known as external reversal, is a reversal transaction initiated externally by the caller.

[0053] Consistency: In a distributed environment, consistency means that data can be kept consistent across multiple copies. When a system performs an update operation in a data consistency state, it should ensure that the system data remains in a consistent state. In a distributed system, if all users can read the latest value of a data item after the update operation is successfully executed, then such a system is considered to have strong consistency.

[0054] Eventual consistency: It emphasizes that all data copies in the system can eventually reach a consistent state after a period of synchronization. This is a concept that is generated relative to real-time strong consistency.

[0055] Figure 1 Schematic diagram of the main process of the transaction processing method of the embodiment of the present invention. Figure 1 As shown, the method includes:

[0056] Step S101: determining a target positive transaction to be stored;

[0057] Step S102: Determine whether there is a first reversal request corresponding to the target positive transaction;

[0058] Step S103: when it is determined that there is a first reversal request corresponding to the target positive transaction, reversing the target positive transaction according to the first reversal request;

[0059] Step S104: After completing the reversal of the target positive transaction, storing the target positive transaction;

[0060] Step S105: When it is determined that there is no first reversal request corresponding to the target positive transaction, directly store the target positive transaction to be stored.

[0061] For step S101, the target positive transaction to be stored refers to a positive transaction that has been executed but not yet stored, that is, after the target positive transaction is executed and before the target positive transaction is recorded in the database, the method of this embodiment is executed.

[0062] For step S102, the reversal process can be understood as a rollback operation on the target transaction. The first reversal request is an outbound reversal request (also referred to as an external reversal request). The opposite of the outbound reversal request is the internal reversal request (i.e., the second reversal request below). The outbound reversal request is a reversal initiated autonomously by the caller from outside the system. The internal reversal is a reversal initiated autonomously from within the system. The first reversal request may be received during the execution of the target transaction. When the first reversal request is received, since the target transaction is being executed and an accurate return status of the transaction has not yet been obtained, the first reversal request is recorded first. After the execution of the transaction is completed and before the database is recorded, it is determined whether there is a first reversal request during the execution of the transaction. If so, a reversal process is performed, and the transaction is recorded in the database after the reversal process is completed. If there is no first reversal request, the transaction is directly recorded in the database.

[0063] In an optional embodiment, if a first reversal request is received after the target positive transaction is successfully executed and before it is stored, the target positive transaction is directly reversal processed according to the first external reversal request, and the positive transaction is recorded in the database after the reversal processing is completed. If the first reversal request is received after the target positive transaction fails to execute and before it is stored, the first reversal request is ignored, and the information that the positive transaction failed to execute is fed back to the initiator of the first reversal request.

[0064] The transaction processing method of the embodiment of the present invention solves the problem of the prior art that the reversal is highly dependent on the reversal to be initiated externally, and the problem of final consistency inconsistency that may be caused when the reversal is not initiated, thereby reducing the occurrence of error messages and the situation that leads to final consistency inconsistency of transaction flows, greatly improving the system stability; reducing the number of interactions with the database, eliminating the need for multiple interactions with the database, and improving the system performance utilization; reducing the need for manual confirmation and initiation of manual reversal, and improving the system stability.

[0065] Figure 2 FIG. 1 is a schematic diagram of the main process of a transaction processing method according to another embodiment of the present invention. Figure 2 As shown, the method includes:

[0066] Step S201: receiving a positive transaction request, wherein the positive transaction request includes a positive transaction to be executed;

[0067] Step S202: executing the pending positive transaction according to the positive transaction request;

[0068] Step S203: Determine the execution status of the transaction;

[0069] Step S204: when it is determined that the positive transaction is successfully executed, the positive transaction to be executed is used as the target positive transaction to be stored;

[0070] Step S205: Determine whether there is a first reversal request corresponding to the target positive transaction;

[0071] Step S206: When it is determined that there is a first reversal request corresponding to the target positive transaction, reversing the target positive transaction according to the first reversal request;

[0072] Step S207: After completing the reversal of the target positive transaction, storing the target positive transaction;

[0073] Step S208: When it is determined that there is no first reversal request corresponding to the target positive transaction, directly store the target positive transaction to be stored.

[0074] Step S209: Initiating a second reversal request when it is determined that the transaction fails to be executed;

[0075] Step S210: reversing the failed transaction according to the second reversal request;

[0076] Step S211: After completing the reversal process of the failed positive transaction, store the positive transaction.

[0077] For a positive transaction, its execution results include successful execution and failed execution. In this embodiment, for a positive transaction that has been successfully executed, before saving it, it is determined whether there is a first reversal request corresponding to it during the execution process. If so, the positive transaction is first reversal processed. After completing the reversal process of the positive transaction, save the positive transaction. For a positive transaction that has failed to execute, after the positive transaction fails to execute, a second reversal request (i.e., an internal call reversal request) for the positive transaction is automatically initiated. Then, the reversal process is performed according to the second reversal request, and the positive transaction is saved after completing the reversal process of the positive transaction. Therefore, the transaction processing method of the embodiment of the present invention solves the problem of relying heavily on external reversal to initiate again in the prior art, and the problem of final consistency inconsistency that may be caused when it is not initiated, reduces error information and the occurrence of situations that lead to final consistency inconsistency of transaction flow, and greatly improves system stability; reduces the number of interactions with the database, and does not need to interact with the database multiple times, which improves system performance utilization; reduces the need for manual confirmation and initiation of manual reversal, and improves system stability.

[0078] Figure 3 Schematic diagram of the sub-process of the transaction processing method of the embodiment of the present invention. Figure 3 The processing process after receiving the first reversal request in the embodiment of the present invention is described. Figure 3 As shown, the process includes:

[0079] Step S301: receiving a first reversal request, parsing the first reversal request, and determining a positive transaction to be reversed corresponding to the first reversal request;

[0080] Step S302: Acquire the transaction status of the transaction to be reversed;

[0081] Step S303: If the transaction status of the transaction to be reversed is in progress, the first reversal request is saved in a preset reversal record table;

[0082] Step S304: If the transaction status of the transaction to be reversed is successful, performing a reversal process according to the first reversal request;

[0083] Step S305: If the transaction status of the transaction to be reversed is execution failure, feedback of transaction failure information is sent to the initiator of the first reverse request.

[0084] In this embodiment, the first reversal request may include the transaction serial number and transaction code of the current transaction to be reversed. The transaction code is used to ensure the safety of the current transaction. If the first reversal request is received, the transaction serial number of the current transaction to be reversed is determined. The transaction status of the current transaction to be reversed is determined based on the transaction serial number:

[0085] If it is determined that the transaction status of the transaction to be reversed is in execution, the first reversal request is saved in a preset reversal record table. Then, the execution of the transaction to be reversed is waited for to be completed. If the transaction to be reversed is successfully executed, it is determined whether there is a corresponding first reversal request in the preset reversal record table. If so, the transaction to be reversed is reversed. After the reversal of the transaction to be reversed is completed, the transaction information of the transaction to be reversed is saved in a database;

[0086] If it is determined that the transaction status of the transaction to be reversed is successfully executed, the transaction to be reversed is reversed according to the first reversal request;

[0087] If it is determined that the transaction status of the current transaction to be reversed is execution failure, transaction failure information is fed back to the initiator of the first reverse request.

[0088] The transaction processing method of the above embodiment is described below by way of example: Assume that there are currently three active transactions, namely active transaction A, active transaction B, and active transaction C.

[0089] If the first reversal request corresponding to the positive transaction A is received, the transaction status of the positive transaction A is obtained. If the transaction status of the positive transaction A is obtained as being executed, the first reversal request is saved in the preset reversal request record table. When the first reversal request is saved, the positive transaction A is still being executed. After the execution of the positive transaction A is completed, if the execution result of the positive transaction A is successful, it is determined whether there is a corresponding first reversal request in the preset reversal request record table. If so, the positive transaction A is reversal processed. After the reversal process of the positive transaction A is completed, the transaction information of the positive transaction A is saved in the database.

[0090] If the first reversal request corresponding to the active transaction B is received, the transaction status of the active transaction B is obtained. If the transaction status of the active transaction B is obtained as successful execution, the active transaction B is reversal processed according to the first reversal request.

[0091] If the first reversal request corresponding to the active transaction C is received, the transaction status of the active transaction C is obtained. If the transaction status of the active transaction C is obtained as execution failure, transaction failure information is fed back to the initiator of the first reversal request.

[0092] The transaction processing method of the embodiment of the present invention records the first reversal request received during the execution of the main transaction, and determines whether there is a corresponding first reversal request after the main transaction is successfully executed and before it is saved. If so, the main transaction is reversal processed. After completing the reversal process of the main transaction, the transaction information of the main transaction is saved in the database, which solves the problem of relying heavily on external reversal to be initiated again in the prior art, and the problem of final consistency inconsistency that may be caused when it is not initiated, reduces error messages and the occurrence of inconsistencies in the final consistency of transaction flows, greatly improves system stability; reduces the number of interactions with the database, does not need to interact with the database multiple times, and improves system performance utilization; reduces the need for manual confirmation and initiation of manual reversal, and improves system stability.

[0093] In an optional embodiment, after determining that the transaction status of the ongoing transaction is in execution, the method may also cyclically query the transaction status of the ongoing transaction. If the transaction status of the target ongoing transaction is found to be successful or failed within a preset number of queries, the transaction status of successful or failed execution is fed back; if the transaction status of the target ongoing transaction is found to be in execution within a preset number of queries, execution exception information is fed back.

[0094] Figure 4 4 is a schematic diagram of the main modules of the transaction processing device 400 according to an embodiment of the present invention. Figure 4 As shown, the transaction processing device 400 includes:

[0095] A determination module 401, used to determine a target positive transaction to be stored;

[0096] A first reversal module 402 is configured to, when determining that there is a first reversal request corresponding to the target positive transaction, perform reversal processing on the target positive transaction according to the first reversal request;

[0098] Optionally, the determination module is also used to: receive a positive transaction request, the positive transaction request including a positive transaction to be executed; execute the positive transaction to be executed according to the positive transaction request; and when it is determined that the positive transaction is executed successfully, use the positive transaction to be executed as the target positive transaction to be stored.

[0099] Optionally, the device also includes a second reversal module, which is used to: initiate a second reversal request when it is determined that the positive transaction has failed to execute; and perform reversal processing on the positive transaction that has failed to execute according to the second reversal request; the storage module is also used to: store the positive transaction after completing the reversal processing of the positive transaction that has failed to execute.

[0100] Optionally, the device further includes: receiving the first correction request, and saving the first correction request.

[0101] Optionally, the receiving module is further used to: receive the first correction request, and save the first correction request in a preset correction record table to generate a first correction request record;

[0102] The first reversal module is also used to: query the reversal record table according to the transaction information of the target transaction; if there is a first reversal request record corresponding to the target transaction in the reversal record table, determine that there is a first reversal request corresponding to the target transaction.

[0103] Optionally, the receiving module is further used to: receive the first reversal request; determine the transaction status of the target transaction; if it is determined that the transaction status of the target transaction is in execution, save the first reversal request in a preset reversal record table.

[0104] Optionally, the device also includes a feedback module, which is used to: if the transaction status of the target transaction is found to be successful or failed within a preset number of queries, then the transaction status of successful or failed execution is fed back; if the transaction status of the target transaction is found to be in execution within a preset number of queries, then execution exception information is fed back.

[0105] Optionally, the storage module is further used to: directly store the target positive transaction when it is determined that there is no first reversal request corresponding to the target positive transaction.

[0106] The transaction processing device of the embodiment of the present invention, by determining that there is a first reversal request corresponding to the target positive transaction to be stored, reversing the target positive transaction according to the first reversal request; after completing the reversal of the target positive transaction, the technical means of storing the target positive transaction solves the problem of the prior art that it is very dependent on external reversal to be initiated again, and the problem of final consistency inconsistency that may be caused when the reversal is not initiated, reduces the occurrence of error information and the occurrence of final consistency inconsistency of transaction flow, greatly improves system stability; reduces the number of interactions with the database, does not need to interact with the database multiple times, and improves system performance utilization; reduces the need for manual confirmation and initiation of manual reversal, and improves system stability.

[0107] The above device can execute the method provided by the embodiment of the present invention, and has the functional modules and beneficial effects corresponding to the execution method. For technical details not described in detail in this embodiment, please refer to the method provided by the embodiment of the present invention.

[0108] Figure 5 This is a flow chart of a transaction processed by a transaction processing device according to an embodiment of the present invention. Figure 5 As shown, when a positive transaction is initiated by the caller to the transaction processing device, the transaction processing device will parse it, and send the transaction to each component or microservice deployment unit through an outbound call / inbound call, and wait for the execution and return of the positive transaction. If the caller initiates an external reversal when the positive transaction is being executed, at this time, since the positive transaction is still in the execution process, the transaction processing device has not yet obtained an accurate return status of the positive transaction, so the external reversal is first recorded. After the execution of the positive transaction is completed and before recording the flow library table, it is determined whether there is an external reversal (i.e., the first reversal request) during the execution of the positive transaction. If so, the reversal process is performed. After the reversal process is completed, the positive transaction is recorded in the database. If there is no external reversal, the positive transaction is directly recorded in the flow library table.

[0109] Figure 6 This is a flow chart of a transaction processed by a transaction processing device according to an embodiment of the present invention. Figure 6As shown, in the processing of external reversal, the caller initiates an external reversal to the transaction processing device. After receiving it, the transaction processing device will first parse the transaction, analyze it as an external reversal, and then obtain the transaction status of the corresponding transaction. If the transaction has been completed, the reversal will be performed. On the contrary, if the transaction is in progress, the external reversal will be recorded, and then the state of the transaction will be queried in a loop. If the transaction status of the transaction is clear, such as successful or failed execution, the transaction status of the transaction will be returned to the caller. If the state of the transaction is not found after the maximum number of loop queries, an error message will be returned. In the subsequent processing of the transaction, before the transaction flow is put into storage (updating the flow table), a query and judgment is made on whether there is an external reversal. If there is, the reversal is processed and then the storage action is performed. If there is no external reversal during the execution of the transaction, the storage action is performed directly. In this way, the final consistency of the transaction flow can be guaranteed.

[0110] Figure 7 This is a flow chart of a transaction processed by a transaction processing device according to an embodiment of the present invention. Figure 7 As shown, in the processing of the positive transaction, the positive transaction is sent by the caller to the transaction processing device. After parsing the message, it is sent to the corresponding microservice or component through internal and external calls to execute the transaction. After the transaction is executed, it returns to the transaction processing device. The transaction processing device will judge the positive transaction before the final storage action. If the positive transaction fails to execute, the subsequent transaction processing device will automatically initiate a correction of the transaction without the need for external correction, so the positive transaction is directly stored in the warehouse at this time. If the positive transaction is successfully executed, it is determined whether there is an external correction initiation during the execution process. If so, the correction process is performed to roll back the positive transaction, and then the storage operation is performed. In this way, the final consistency of the positive transaction can be guaranteed without the external correction being initiated again, eliminating unnecessary errors and the time and efficiency of subsequent manual processing, greatly improving the system's self-rotation.
