Accordingly, the transaction processing apparatus applied to the distributed system provided by the embodiments of the present disclosure can also be arranged in a server or a server cluster different from the server 105 and capable of communicating with the terminal device 101, 102, 103 and / or the server 105.

[0056] It should be understood that Figure 1 The number of terminal devices, networks and servers in the system is only illustrative. According to the needs of implementation, there can be any number of terminal devices, networks and servers.

[0057] The transaction processing method applied to the distributed system of the embodiments of the present disclosure will be described in detail based on the scenario described below. Figure 1 Figures 2-4 The transaction processing method applied to the distributed system of the embodiments of the present disclosure will be described in detail based on the scenario described below.

[0058] Figure 2 The flowchart of the transaction processing method applied to the distributed system according to the embodiments of the present disclosure is schematically shown.

[0059] As shown in Figure 2 The transaction processing method applied to the distributed system of the embodiments includes operations S210-S240.

[0060] In operation S210, in response to the transaction request instruction initiated by the first account end to the second account end, the first state information of the first account end and the second state information of the second account end are obtained.

[0061] In the embodiments of the present disclosure, the consent or authorization of the user can be obtained before the information of the user is obtained. For example, before operation S210, the user can be requested to obtain the user information. In the case where the user agrees or authorizes that the user information can be obtained, the operation S210 is executed.

[0062] According to the embodiments of the present disclosure, for example: the transaction request instruction initiated by the first account end to the second account end can be that the account A transfers 100,000 yuan to the account B. At this time, the first state information of the first account end account A obtained can include whether the account A exists, whether it is in a normal state and the balance state in the account A. The second state information of the second account end account B can include whether the account B exists, whether it is in a normal state and the balance state in the account B, etc. ​

[0063] In operation S220, the first information is sent to the first account end in a case where the first state information and the second state information satisfy a preset condition, wherein the first information comprises the first state information and the transaction amount information.

[0064] According to an embodiment of the present disclosure, for example: the first state information is that the account A exists and is normal, and the balance of the account A is 500,000 yuan. The second state information is that the account B exists and is normal, and the balance of the account B is 50,000 yuan. At this time, both the account A and the account B exist and are normal, and the balance of the account A is 500,000 yuan, which is greater than the transaction amount of 100,000 yuan. The first information can be sent to the first account end. The first information can include the state information of the account A: the account A exists and is normal, the balance of the account A is 500,000 yuan, and the account A deducts the transaction amount of 100,000 yuan.

[0065] According to an embodiment of the present disclosure, for example: the first state information is that the account A exists and is normal, and the balance of the account A is 50,000 yuan. The second state information is that the account B exists and is normal, and the balance of the account B is 50,000 yuan. At this time, the balance in the account A is less than the transaction balance of 100,000 yuan, which is insufficient to deduct the transaction amount, and the transaction fails.

[0066] In operation S230, the first processing result information is received, which is obtained by the first account end according to the transaction amount information in a case where the current state information of the first account end is the same as the first state information.

[0067] According to an embodiment of the present disclosure, for example: the current state information of the first account end is that the account A exists and is normal, and the balance is 500,000 yuan. Then, the current state information of the first account end is the same as the first state information, and the transaction amount of 100,000 yuan can be deducted from the account A. After the deduction, the balance information of the account A is 400,000 yuan. Then, the first processing result information received can be that the transaction is successful or the balance change is successful.

[0068] According to an embodiment of the present disclosure, for example: the current state information of the first account end is that the account A exists and is normal, and the balance is 300,000 yuan. Then, the current state information of the first account end is different from the first state information, and the balance change operation is not performed. Then, the first account end feeds back the processing result information that the transaction fails or the balance change is failed to the service end.

[0069] In operation S240, the second information is sent to the second account end in a case where the first processing result information is that the transaction is successful, wherein the second information comprises the transaction amount information, so that the second account end changes the balance information of the second account according to the transaction amount information to obtain the second processing result information.

[0070] According to an embodiment of the present disclosure, for example, in the case that the first processing result information is transaction success, the second information is sent to the second account end account B, the second information can be the transaction amount of 100,000 yuan transferred to the account B, and the second account end account B can increase the transaction amount of 100,000 yuan in the account B, and the balance information of the account B is changed to 150,000 yuan.

[0071] According to an embodiment of the present disclosure, by acquiring the first state information of the first account end and the second state information of the second account end, in the case that the first state information and the second state information satisfy the preset condition, the first information is sent to the first account end, and in the case that the transaction success processing result information fed back by the first account end is received, the second information is further sent to the second account end, so that the second account end changes the balance information of the second account according to the transaction amount information, and obtains the second processing result information. The technical means of checking the state information of the first account end and further sending the first information to the first account end can effectively avoid repeated processing of the transaction, and ensure the final consistency of the single transaction information processed by the two account ends.

[0072] According to an embodiment of the present disclosure, the first information and the second information both include transaction identification information, the transaction identification information is used to represent the transaction information in the request instruction, and further includes:

[0073] The first processing result information and the transaction identification information are recorded in the transaction log of the first account end;

[0074] The second processing result information and the transaction identification information are recorded in the transaction log of the second account end.

[0075] According to an embodiment of the present disclosure, for example, the transaction identification information can be identified by the hash value of the transaction information in the request instruction as a key value. In the case that the first processing result information and the second processing result information are both transaction success, the transaction log of the first account end can record <key, timestamp, success>; and the transaction log of the second account end can record <key, timestamp, success>. The transaction log can include time information of the transaction request instruction, which is used to distinguish different transactions with the same transaction information. The transaction identification information can also be used to distinguish different transactions with the same transaction information but different transaction times by using a hash algorithm.

[0076] According to an embodiment of the present disclosure, the processing results of the two account ends and the transaction identification information are recorded in the respective transaction logs, and whether the transaction has been processed can be identified by the transaction identification information, which can effectively avoid repeated processing or missed processing of the transaction.

[0077] According to an embodiment of the present disclosure, the transaction processing method applied to the distributed system further includes:

[0078] In a case where the first processing result information is not received within the preset time, third information is sent to the first account end, wherein the third information comprises first state information of the first account end, transaction amount information, transaction identification information and a repeat mark;

[0079] The third processing result information is received, wherein the third processing result information is obtained by the first account end according to the transaction amount information in a case where the current state information of the first account end is the same as the first state information and the transaction identification information does not exist in the transaction log of the first account end.

[0080] According to the embodiment of the present disclosure, due to communication problems such as network timeout, the service end does not receive the first processing result information fed back by the first account end within the preset time, and the third information can be sent to the first account end again. For example, the third information can comprise the first state information that the account A exists and is normal and the balance is 500,000 yuan, and the transaction amount information that the account A deducts 100,000 yuan, and further comprises the transaction identification information key value and the repeat mark repeat.

[0081] According to the embodiment of the present disclosure, when the first account end receives the third information with the repeat mark repeat, it is necessary to first check whether the current state of the first account end account A is the same as the first state information of the account A in the third information. If they are the same, it is further necessary to check whether the key value representing the transaction identification information exists in the transaction log of the first account end. If the key value does not exist, the transaction is processed, that is, according to the transaction amount information of 100,000 yuan, the balance information of the account A is changed from 500,000 yuan to 400,000 yuan.

[0082] According to the embodiment of the present disclosure, when the first account end receives the third information with the repeat mark repeat, if the current state of the first account end account A is not the same as the first state information in the third information, the transaction is processed as a new transaction.

[0083] According to the embodiment of the present disclosure, in a case where the current state information of the first account end is the same as the first state information, and the transaction identification information exists in the transaction log of the first account end, the first processing result information recorded in the transaction log of the first account end is received.

[0084] According to the embodiment of the present disclosure, for example, when the first account end receives the third information with the repeat mark repeat, if the current state of the first account end account A is the same as the first state information in the third information, and the key value representing the transaction identification information exists in the transaction log of the first account end. The service end is fed back with the transaction success and the processing result information recorded in the transaction log of the first account end, that is, the balance information of the account A is changed to 400,000 yuan.

[0085] According to the embodiments of the present disclosure, by checking the information with the repeat mark and the transaction identification information, the problem that the transaction information repeatedly sent by the server is repeatedly processed due to the network communication timeout feedback processing result to the server can be effectively avoided.

[0086] According to the embodiments of the present disclosure, in the case that the second processing result information is not received within the preset time, the fourth information is sent to the second account end, wherein the fourth information includes transaction amount information, transaction identification information and repeat mark;

[0087] The fourth processing result information is received, wherein the fourth processing result information is obtained by the second account end according to the transaction amount information in the case that the transaction identification information does not exist in the transaction log of the second account end.

[0088] According to the embodiments of the present disclosure, due to the network timeout and other communication problems, the server does not receive the second processing result information fed back by the second account end within the preset time, and the fourth information can be sent to the second account end again, for example: the fourth information can include the transaction amount information of 100,000 yuan transferred to account B, and also include the transaction identification information key value and repeat mark.

[0089] According to the embodiments of the present disclosure, when the second account end receives the fourth information sent by the server, it is necessary to check whether the key value representing the transaction identification information exists in the transaction log of the second account end, if not, continue to change the balance of account B, and change the balance of account B from 50,000 to 150,000.

[0090] According to the embodiments of the present disclosure, if the key value representing the transaction identification information exists in the transaction log of the second account end, it means that the transaction has been processed, and the second processing result information recorded in the transaction log can be fed back to the server.

[0091] According to the embodiments of the present disclosure, by checking the information with the repeat mark and the transaction identification information, the problem that the transaction information repeatedly sent by the server is repeatedly processed due to the network communication timeout feedback processing result to the server can be effectively avoided.

[0092] According to the embodiments of the present disclosure, in the case that the second processing result information is transaction failure, the fifth information is sent to the first account end, wherein the fifth information includes transaction amount information;

[0093] The fifth processing result information is received, wherein the fifth processing result information is obtained by the first account end according to the transaction amount information and the balance information of the first account end.

[0094] According to an embodiment of the present disclosure, for example, the second processing result information is a transaction failure, which generally occurs when the account B is cancelled in a short time, resulting in the failure of the account entry transaction of the second account side. When this occurs, the server sends the fifth information to the first account side to initiate a reverse transaction. The fifth information can include a transaction amount of 100,000 yuan transferred to the account A. The first account side changes the balance of the account A from 400,000 yuan to 500,000 yuan.

[0095] According to an embodiment of the present disclosure, by monitoring the transaction processing result of the second account side by the server, the reverse transaction is performed for the transaction failure of the second account side, and the amount deducted from the corresponding account of the first account side is returned in time, without affecting the performance of other transactions.

[0096] According to an embodiment of the present disclosure, the preset condition includes that the account status of the first account side and the second account side is normal, and the account balance of the first account side is greater than the transaction amount in the transaction request instruction.

[0097] According to an embodiment of the present disclosure, for example, the server receives a transaction request instruction that the account A pays 100,000 yuan to the account B, and determines whether to perform the transaction by obtaining the status information of the first account side and the second account side. If the account A is normal and the account B is cancelled, the preset condition is not met, and the server does not perform the transaction processing operation in the embodiment of the present disclosure. If the account A is normal and the account B is normal, but the account balance of the account A is 50,000 yuan, which is less than 100,000 yuan, the preset condition is not met, and the server does not perform the transaction processing operation in the embodiment of the present disclosure.

[0098] According to an embodiment of the present disclosure, by setting the preset condition, the account status involved in the transaction is queried and judged before the transaction processing is performed, which can effectively reduce the invalid transaction processing information sent by the server to the first account side or the second account side, and improve the timeliness of the transaction processing of the entire distributed system.

[0099] Figure 3 A logic block diagram of a transaction processing method applied to a distributed system according to an embodiment of the present disclosure is schematically shown.

[0100] As shown in Figure 3 , the embodiment includes operations S301-S310.

[0101] In operation S301, in response to the transaction request instruction initiated by the first account side to the second account side, the first status information of the first account side and the second status information of the second account side are obtained.

[0102] In operation S302, it is determined whether the first status information and the second status information meet the preset condition, if yes, operation S303 is performed; if not, operation S304 is performed.

[0103] In operation S303, the first processing result information is received. The first processing result information is obtained by the first account terminal changing the balance information of the first account terminal according to the transaction amount information, when the current status information and the first status information of the first account terminal are the same.

[0104] When operating S304, a transaction failure report is sent to the client.

[0107] In operation S307, the second processing result information is received and identified; if the second processing result information indicates a successful transaction, operation S308 is executed; if the second processing result information indicates a failed transaction, operations S304 and S309 are executed.

[0108] When operating S308, a successful transaction notification is sent to the client.

[0109] In operation S309, the fifth information is sent to the first account, which includes transaction amount information;

[0110] During operation S310, the fifth processing result information is received. This fifth processing result information is obtained from the first account based on the transaction amount information and the balance information of the first account.

[0111] Figure 4 The illustration schematically depicts an exemplary architecture of an application distributed system for a transaction processing method according to embodiments of the present disclosure.

[0112] like Figure 4 As shown, the distributed system 400 includes a client 401, a server 402, a first account terminal 403, and a second account terminal 404.

[0113] Client 401 initiates a transaction request from first account 403 to second account 404. After receiving the transaction request, server 402 obtains the status information of first account 403 and second account 404. The status information of first account 403 and second account 404 can be v respectively. a v b .

[0114] When the preset condition is met, the server 402 assembles transaction information according to the transaction request, and records the transaction log, for example: .

[0115] The key in the transaction log is used as the unique transaction identification information for identifying the transaction in the distributed system. The transaction information can be assembled into a transaction package:

[0116] .

[0117] Wherein, P represents the first account end, i.e. the payment account; Q represents the second account end, i.e. the receiving account.

[0118] The server 402 executes the transaction processing method applied to the distributed system of the embodiments of the present disclosure to process the transaction. For example, the first information is sent to the first account end: .

[0119] After receiving the transaction success information fed back by the first account end 403, the server 402 sends the second information to the second account end 404: .

[0120] After receiving the transaction success information fed back by the second account end 404, the server 402 feeds back the transaction success information to the client 401. If the transaction failure information fed back by the second account end 404 is received, the server 402 sends the reverse transaction information (fifth information) to the first account end 403, and feeds back the processing result of the first account end to the client 401.

[0121] According to the embodiments of the present disclosure, the transaction sub-ledger information recorded by the first account end 403 and the second account end 404 is shown in the following table:

[0122] Account Updating account balance Updating transaction log A B

[0123] Figure 5 The application scenario schematic diagram of the embodiments of the present disclosure implemented in the same institution is schematically shown;

[0124] As shown in Figure 5 , in the application scenario 500, the client 501, the server 502, the client group A 503, the client group B 504, and the client group C 505 are included.

[0125] Under the same institution, the clients can be grouped by account information, and a distributed system with node eventual consistency is established, and the accounts of the client group A 503, the client group B 504, and the client group C 505 do not interact.

[0126] Client 501 initiates a transfer transaction request between client group A503, client group B504, and client group C505. Server 502 executes the transaction processing method for distributed systems provided in this embodiment of the disclosure, and is responsible for sending transaction information to client group A503, client group B504, and client group C505 respectively and receiving information from client group A503, client group B504, and client group C505. Based on the final transaction processing result, it sends the transaction processing result information back to client 501.

[0127] Figure 6 The illustrations depict application scenarios of implementing embodiments of the present disclosure in different institutions;

[0128] like Figure 6 As shown, in this application scenario 600, there are server 601, customer A 602, customer B 603 and internal transition user 604.

[0129] Server 601 can process customer A602 and customer B603 respectively according to the transaction processing method for distributed systems provided in this embodiment of the present disclosure. When both customer A602 and customer B603 report successful transactions to server 601, server 601 sends a transaction information packet to internal intermediary 604.

[0130]

[0131] Based on the transaction amount information in the transaction information packet, internal transition account 604 is processed according to the eventual consistency algorithm to obtain the transaction ledger information of internal transition account 604 as shown in the table below:

[0132] Account Balance Debit occurrence Credit occurrence Updating transaction log C Unchanged x x

[0133] If the server does not receive feedback from internal transition user 604 within a preset time, it will resend the transaction packet with a duplicate tag to internal transition user 604. When internal transition user 604 receives the transaction packet with the duplicate tag, it queries the transaction log. If the key value from the transaction packet exists in the transaction log, it feeds back to the server 601 based on the result of the transaction log. If the key value from the transaction packet does not exist in the transaction log, it is processed according to the eventual consistency algorithm.

[0134] According to embodiments of this disclosure, the present invention can provide adaptive processing solutions for "one borrowing and one lending," "one borrowing and multiple lending," and "multiple borrowing and one lending" scenarios in transfer transactions. For example, in the "one borrowing and multiple lending" scenario, a second message can be sent concurrently to the receiving account after the unilateral transaction on the payment account. As for the "multiple borrowing and one lending" scenario, it can be decomposed into multiple "one borrowing and one lending" scenarios for processing.
