Detailed Description

The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a schematic flow chart of a transaction processing method according to an embodiment of the present application, where the present embodiment is applicable to a case where a host system moves down to a distributed system for transaction processing, and the method may be executed by a transaction processing apparatus, and the apparatus may be implemented in a software and/or hardware manner, as shown in fig. 1, the method specifically includes the following steps:

s110, carrying out transaction processing on any transaction in a transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode; wherein the transaction processing includes at least one processing node.

The SAGA distributed transaction mode (hereinafter referred to as SAGA mode) is a distributed transaction implementation mode based on compensation transactions, and in the SAGA mode, a distributed transaction may include a plurality of transactions, where each transaction supports a forward transaction and a reverse compensation transaction. When the distributed transaction in the SAGA mode is executed, forward transactions of all transactions are executed in sequence, and if the forward transactions of all transactions are executed successfully, the distributed transaction is submitted. If the forward transaction execution of any transaction fails, the distributed transaction executes the reverse compensation transaction corresponding to the completed forward transaction, i.e. backs up the successful forward transaction, and returns the distributed transaction to the initial state. The SAGA mode and the transaction processing logic of the host system have high adaptation degree, and the transaction processing of the distributed system moved down by the host system can be realized without greatly improving the SAGA mode.

Generally, a transaction chain of distributed transactions is executed according to a certain service execution sequence, that is, each transaction in the distributed transactions is processed according to a transaction execution sequence, and the transaction execution sequence corresponding to the distributed transactions may be an execution sequence of the service or a transaction execution sequence corresponding to an SAGA mode. For example, the loan transaction execution sequence corresponding to the distributed transaction may be, in turn, verifying the validity of the account number of the client, verifying the password of the account number, the amount of the deducting party and the amount of the transferring party. Any transaction may be any one of transactions a1, a2, …, An in SAGA mode. For example, the transaction may be a loan transaction.

For example, the distributed master control may perform transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode. The distributed master control can be used as a distributed system application gateway, is a uniform entrance of a distributed system, and is mainly responsible for providing functions of access control, safety control, public application inspection, distributed transaction global transaction number distribution and the like of application processing or transaction processing, wherein the distributed transaction global transaction number is a distributed ID. Wherein, at least one processing node can be included in the transaction processing process of each transaction. Different transactions can be processed by different server nodes in the distributed system, and the distributed general control initiates and calls each server node. For example, the transaction process may include a funds process or other business process, wherein the funds process may be a money transfer process or other process involving a transfer of funds, and the other business process may be a credit process, a credit review process, or an information registration process, etc.

In an optional embodiment, before performing transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode, the method further includes: determining a target verification program corresponding to any transaction from preset candidate verification programs; according to the target verification program, verifying the transaction and judging whether the transaction passes the verification; if yes, carrying out transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode.

The candidate verification procedure may be preset by a person of ordinary skill in the art. For example, the verification programs corresponding to different transactions may be stored in advance in the server associated with the processing node corresponding to each transaction. The target verification program may be a verification program corresponding to any transaction, which is deployed in the candidate verification programs of the processing node association servers. The candidate verification program can comprise account password verification, card number existence verification, card number freezing verification, deposit validity verification, transaction channel verification and the like.

Exemplarily, a target verification program corresponding to any transaction is determined from preset candidate verification programs; according to the target verification program, verifying the transaction and judging whether the transaction passes the verification; if yes, carrying out transaction processing on any transaction in a transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode; if not, the transaction verification failure reminding information can be sent to related personnel, and the transaction processing is stopped. The transaction failure reminding information may be a reason for reminding the failure of the verification, for example, the transaction failure reminding information may be the failure of the verification of an account number and a password or the absence of a card number, and different transaction failure reminding information may be set by related staff according to different transactions.

In the optional embodiment, before transaction processing is performed on any transaction, any transaction is verified according to a preset target verification program associated with any transaction, whether the transaction passes the verification is judged, and if the transaction passes the verification, subsequent transaction processing is executed, so that the safety of the subsequent transaction processing process is improved, and the economic loss caused by information verification errors or information omission of a transaction party is avoided.

And S120, if the processing node of the transaction is a fund transfer node, acquiring fund flow information of the transaction, sending the fund flow information to a fund processing center, and preparing and processing the fund transfer of the transaction by the fund processing center based on a TCC (transmission control center) distributed transaction mode according to the fund flow information.

Where the funds-transfer node is used to perform funds processing, i.e. any processing in a transaction involving funds, such as deposit or deposit, etc. The funds movement information may include an initiation time, an initiation amount, a remaining amount, and the like. The funds-processing center may be a server node for performing funds processing in a distributed system. For example, confirmation and payout of funds by the funds processing center, etc.

The TCC distributed transaction mode (hereinafter, referred to as TCC mode) is an abbreviation of three operations of Try or prepare operation (Try), Confirm operation (Confirm), and Cancel operation (Cancel), and the TCC mode guarantees atomic commit of distributed transactions, traffic isolation controls concurrent access of distributed transactions, and transactional consistency of distributed transactions by atomicity.

The business implications of the three operations of the TCC mode are: the Try phase is used to complete all service checks and reserve necessary service resources. Wherein the service may be a funds handling service; a Confirm stage: the really executed service logic confirms and submits the service without any service check, and only uses the service resources reserved in the Try stage. The default Confirm stage does not make mistakes, and as long as Try succeeds, Confirm succeeds; a Cancel stage: and when the service execution has errors and needs to be rolled back, executing service cancellation and releasing the reserved service resources.

For example, the acquired fund flow information of the transaction can be sent to the fund processing center by the distributed general control. After the fund processing center acquires the fund flow information, the transaction is prepared based on the TCC distributed transaction mode, namely the transaction is subjected to Try operation.

S130, judging whether any processing node of the transaction passes execution, if so, judging whether the transaction is a target transaction of a preset arrangement sequence in a transaction execution sequence.

Any of the processing nodes may include a funds transfer node and other business processing nodes, among others. For example, the other business processing nodes may be credit processing nodes or information auditing processing nodes, etc. The preset arrangement order may be preset by a related art person, for example, the preset arrangement order may be a position of a last processing node located in the transaction execution order. The target transaction may be the transaction corresponding to the last processing node located in the transaction execution order.

And judging whether all processing nodes of the transaction pass execution, if so, judging whether the transaction is a target transaction arranged at the last position in the transaction execution sequence.

And S140, if so, sending a fund transfer confirmation instruction to the fund processing center, and confirming the fund transfer preparation processing of any transaction in the transaction execution sequence by the fund processing center.

For example, if the transaction is a target transaction in a preset arrangement order in the transaction execution order, for example, the transaction is the last transaction in the transaction execution order, it may be determined that all transactions corresponding to the distributed transactions are executed through. Confirmation instructions for the funds transfer may be sent to the funds processing center via the distributed grandmaster. After receiving the confirmation instruction of the fund transfer, the fund processing center performs confirmation operation on the preparation processing of the fund transfer of any transaction in the transaction execution sequence, namely, the fund processing center performs confirm operation on the fund transfer of any transaction of the Try which is successfully performed according to the TCC mode.

In an alternative embodiment, the distributed transaction corresponds to a unique distributed ID, and the funds movement information includes the distributed ID; the fund processing center comprises fund flow information of a plurality of distributed transactions; correspondingly, sending a confirmation instruction of the fund transfer to the fund processing center, and confirming the fund transfer preparation processing of any transaction in the transaction execution sequence by the fund processing center, wherein the confirmation instruction comprises the following steps: and sending a fund transfer confirmation instruction corresponding to the distributed ID to the fund processing center, determining the target fund flow information by the fund supply processing center according to the distributed ID, and confirming the fund transfer preparation corresponding to the target fund flow information.

Where the distributed id (identity) may represent a unique identification of the distributed transaction in the distributed system. For example, the distributed ID may be generated by a snowflake algorithm, which generates an ID that is a 64bit Long type number, which is an incremental number that may be used for sorting. The snowflake algorithm can basically keep global uniqueness. The target funds movement information may be funds movement information corresponding to each transaction under the distributed ID.

For example, the distributed grandmaster may generate a distributed ID and transmit it to any transaction, i.e. the distributed ID of each transaction in the transaction execution sequence of a distributed transaction is the same; and in the fund processing process of any transaction, when the fund flow information is sent to the fund processing center, the fund flow information comprises the distributed ID of the transaction. When the fund transfer of any transaction is completely prepared (namely all Trys are successful), the distributed master control can initiate a fund transfer confirmation instruction corresponding to each transaction under the distributed ID to the fund processing center through the distributed ID; and after receiving the fund transfer confirmation instruction, the fund processing center determines the fund flow information under the distributed ID as the target fund flow information, and confirms the fund transfer preparation process corresponding to the target fund flow information, namely confirms the successful fund flow of all Try under the distributed ID.

In the optional embodiment, the unique distributed ID corresponding to the distributed transaction is determined, and the confirmation instruction of the fund transfer is initiated to the fund processing center according to the distributed ID, so that the condition that the submission error of the fund transfer action occurs when at least one distributed transaction exists is avoided. The uniqueness and accuracy of the confirmed fund transfer instruction can be ensured by setting the distributed ID.

According to the SAGA distributed transaction mode, transaction processing is carried out on the transaction corresponding to the distributed transaction; if the processing node of the transaction is a fund transfer node, preparing and processing the fund transfer of the transaction by the fund processing center according to the fund flow information and based on a TCC (transmission control center) distributed transaction mode; if any processing node including the fund processing node passes in any transaction, the transaction processing execution pass corresponding to the distributed transaction can be determined, and the fund processing center can confirm the fund transfer preparation processing of any transaction in the transaction execution sequence. According to the scheme, the fund processing is extracted from the transaction processing logic, the nodes related to the fund processing in the transaction processing are processed according to the TCC mode, and other non-fund transactions are processed according to the transaction implementation logic of the SAGA mode, so that the transaction processing in the process that the host system moves down to the distributed system is realized, and the fund security in the transaction processing process is improved. The fund transfer preparation process is confirmed after the transaction process of any transaction is passed, so that the situation that the fund cannot return in the fund transfer process is avoided. Transaction consistency in the transaction processing process is achieved.

Fig. 2 is a schematic flow chart of a transaction processing method according to a second embodiment of the present application, and the second embodiment of the present application performs optimization and improvement on the basis of the foregoing technical solutions.

Further, after the step of performing transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode, the step of adding the step of acquiring the information to be confirmed of the transaction and confirming the information to be confirmed if the processing node of the transaction is the information confirmation node is added. To complete the transaction processing for any transaction.

After the step of judging whether any processing node of the transaction executes the passing, the step of adding is carried out, if any processing node of the transaction does not execute the passing, whether the processing node which does not execute the passing is the fund transfer node is judged; if yes, sending a fund transfer canceling instruction to the fund processing center, and canceling the preparation processing of fund transfer by the fund supply processing center. Correspondingly, after the step of judging whether the processing node which does not pass through the execution is a fund transfer node, the step of adding is that if the processing node which does not pass through the execution is not the fund transfer node, the processing node which passes through the execution in the transaction is determined, and the transaction which passes through the execution is determined according to the execution sequence of the transaction; and according to a preset reverse compensation transaction rule, transaction rollback is carried out on the processing nodes which have passed the execution in the transaction and the transactions which have passed the execution in the transaction execution sequence. "to perfect the way non-funds-transfer nodes are handled.

After the step of judging whether the transaction is the target transaction of the preset arrangement sequence in the transaction execution sequence, the step of adding the step of determining the next transaction of the transaction according to the transaction execution sequence if the transaction is not the target transaction of the preset arrangement sequence in the transaction execution sequence, taking the next transaction as the transaction to be processed, and executing the transaction processing on the transaction to be processed in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode. "to refine the way non-targeted transactions are processed.

As shown in fig. 2, the method comprises the following specific steps:

For example, the information confirmation node may comprise a processing node for the quota and an information auditing processing node, etc. The information to be confirmed corresponds to each information confirmation node, for example, if the information confirmation node is a credit processing node, the information to be confirmed may be credit information to be confirmed.

And S230, if the processing node of the transaction is a fund transfer node, acquiring fund flow information of the transaction, sending the fund flow information to a fund processing center, and preparing and processing the fund transfer of the transaction by the fund processing center based on a TCC (transmission control center) distributed transaction mode according to the fund flow information.

And S260B, determining the next transaction of the transactions according to the transaction execution sequence to be used as a to-be-processed transaction, and executing the transaction processing of the to-be-processed transaction in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction mode.

S270A, sending a fund transfer canceling instruction to the fund processing center, and canceling the fund transfer preparation processing by the fund processing center.

For example, a fund transfer cancellation command may be sent by the distributed general control to the fund processing center, and the fund processing center cancels the prepared fund transfer according to the fund transfer cancellation command. That is, the funds processing center can cancel all funds that have been successful for the Try.

S270B, determining the processing nodes which have passed through in the transaction, and determining the transaction which has passed through according to the transaction execution sequence.

And returning the executed transaction in the transaction processing nodes and the executed transaction in the transaction execution sequence. For any transaction that fails to execute, the distributed transaction will fall back to execute the reverse compensation transaction of any previously completed transaction, and fall back to the successful transaction, so that the distributed transaction returns to the initial state before transaction processing is not performed.

The embodiment of the application further improves the transaction processing process of any transaction by further taking the processing node of the transaction as the information confirmation node, if any processing node of the transaction does not execute the transaction, and if the transaction is not the target transaction of the preset arrangement sequence in the transaction execution sequence. The fund processing is extracted from the transaction processing logic, the nodes related to the fund processing in the transaction processing are processed according to the TCC mode, and other non-fund transactions are processed according to the transaction implementation logic of the SAGA mode, so that the transaction processing in the process that the host system moves down to the distributed system is realized, and the fund security in the transaction processing process is improved.

In one embodiment, the distributed master generates a global transaction number X (distributed ID), and submits transactions a1, a2, …, An with global transaction numbers not X in sequence according to the execution order of the SAGA mode. A verification routine is performed for each transaction Ai. Transaction processing is performed on Ai, including fund processing to trade Ai, fund processing pipeline to generate Ai, and other non-fund business processing. Wherein, the fund processing mode to Ai is: and sending the fund flow information to a fund processing center, and submitting the try action of the fund flow with the global transaction number X by the fund processing center one by one according to the TCC mode. And if a certain transaction Ai fails to be executed, based on the SAGA mode, backing back the transaction Aj according to the reverse compensation transaction of the executed successful transaction Aj, and informing the fund processing center by the distributed master control to back all fund flow of the successful try corresponding to the global transaction number X. If the transactions A1, A2, … and An of the whole transaction chain are completely executed and the try action with the global transaction number of X fund flow is completely successful, the distributed master control informs the fund processing center to execute all fund processing flows under the global transaction number X to perform confirm action, and the whole transaction chain is successfully submitted.

In a transaction nesting scenario, if a transaction P relates to a distributed transaction, the transaction P includes a service one, a service two, and a service three, wherein the service two includes a service four and a service five, a distributed transaction nesting is generated, and on the premise that the fund processing is stripped from the transaction, the transaction P calls the service one, the service two, and the service three to be an SAGA mode, and the service two calls the service four and the service five to be also an SAGA mode. The distributed master control service II is informed of success only after the service IV and the service V are all successful; and if any of the service four and the service five fails, all the services return back and tell the distributed total control service two that the failure occurs. And if the second service fails, backing back the successfully executed service.

If the service II does not comprise the service IV and the service V, and the service I, the service II, the service III, the service IV and the service V are in parallel relation, the whole transaction chain is changed into the service I, the service II, the service III, the service IV and the service V, the services are still executed in sequence in the SAGA mode, and if a certain service fails to be submitted, the compensation transaction is submitted for the successful service, and all the services are returned.

For fund processing, the whole fund processing flow of the transaction is executed according to a TCC mode, specifically for a certain fund flow, if the try function also relates to a distributed service sub-call, the fund flow try action can be known to be backspacing, the distributed service sub-call related to the try action can be backspacing, otherwise, the backspacing of the whole try action cannot be ensured. For a certain fund flow, its confirm function relates to distributed service sub-call, and the success of the fund flow confirm, the success of the distributed service sub-call, and the asynchronous message informing mode can initiate the distributed service sub-call, as long as the message can be sent to the success.

In the new and old system transaction combination scenario during host system move down, it is necessary to ensure the transaction consistency of the new and old system transactions combined with each other. The host system can be considered as a typical SAGA mode, the newly-realized distributed system can be considered as a system meeting the TCC mode condition, and the mode of combining the TCC mode and the SAGA mode can be used for ensuring the transaction consistency and the fund safety.
