A transaction processing method applied to a distributed system of the disclosed embodiment will be described in detail below with reference to fig. 2 to 4 based on the scenario described in fig. 1.
Fig. 2 schematically shows a flow chart of a transaction processing method applied to a distributed system according to an embodiment of the present disclosure.
As shown in fig. 2, the transaction processing method applied to the distributed system of this embodiment includes operations S210 to S240.
In operation S210, in response to a transaction request instruction initiated by a first account to a second account, first state information of the first account and second state information of the second account are obtained.
In embodiments of the present disclosure, prior to obtaining information of a user, consent or authorization of the user may be obtained. For example, a request for obtaining user information may be issued to the user before operation S210. In case that the user information can be acquired with the user' S consent or authority, the operation S210 is performed.
According to an embodiment of the present disclosure, for example: the transaction request command initiated by the first account terminal to the second account terminal may be shifted to 10 ten thousand yuan from account a to account B. At this time, the acquired first state information of the first account-side account a may include whether the account a exists, whether the account a is in a normal state, and a balance state in the account a. The second status information of the second account-side account B may include whether the account B exists, whether the account B is in a normal status, a balance status in the account B, and the like.
In operation S220, in a case that the first state information and the second state information satisfy a preset condition, first information is sent to the first account terminal, where the first information includes the first state information and transaction amount information.
According to an embodiment of the present disclosure, for example: the first status information is that account a exists and is normal, and the balance of account a is 50 ten thousand yuan. The second state information is that account B exists and is normal, and the balance of account B is 5 ten thousand yuan. At this time, the account a and the account B exist and are normal, the balance of the account a is 50 ten thousand yuan greater than the transaction amount by 10 ten thousand yuan, and the first information may be sent to the first account side. The first information may include status information of account a: account a exists and is normal, the balance of account a is 50 ten thousand dollars, and account a deducts 10 ten thousand dollars of transaction amount.
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 5 ten thousand yuan. The second state information is that account B exists and is normal, and the balance of account B is 5 ten thousand yuan. At this time, the balance in the account a is less than 10 ten thousand yuan less than the transaction balance, and the transaction fails if the transaction amount is not deducted enough.
In operation S230, first processing result information is received, where the first processing result information is obtained by the first account terminal changing balance information of the first account terminal according to the transaction amount information when the current state information of the first account terminal is the same as the first state information.
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 50 ten thousand yuan, then the current state information of the first account end is the same as the first state information, and the balance information of the account a is 40 ten thousand yuan after the transaction amount is deducted from the account a according to the transaction amount of 10 ten thousand yuan. The received first processing result information may be a transaction success or a balance change success.
According to an embodiment of the present disclosure, for example: and if the current state information of the first account end is that the account A exists and is normal, and the balance is 30 ten thousand yuan, the current state information of the first account end is different from the first state information, and the balance change operation is not executed. The first account side feeds back the processing result information of the transaction failure or the balance change to the server side.
In operation S240, when the first processing result information is that the transaction is successful, second information is sent to the second account terminal, where the second information includes transaction amount information, so that the second account terminal changes balance information of the second account according to the transaction amount information to obtain second processing result information.
According to an embodiment of the present disclosure, for example: and sending second information to a second account side account B under the condition that the first processing result information is that the transaction is successful, wherein the second information can be that 10 ten thousand yuan is transferred to the account B, and the balance information of the account B is changed into 15 ten thousand yuan after the transaction amount is added to the account B according to the transaction amount of 10 ten thousand yuan by the second account side account B.
According to the embodiment of the disclosure, by acquiring the first state information of the first account end and the second state information of the second account end, sending the first information to the first account end under the condition that the first state information and the second state information meet the preset condition, and sending the second information to the second account end under the condition that the processing result information of successful transaction fed back by the first account end is received, so that the second account end changes the balance information of the second account according to the transaction amount information to obtain the technical means of the second processing result information, by checking the state information of the first account end and then sending the first information to the first account end, the transaction can be effectively prevented from being processed repeatedly, and the final consistency of unilateral transaction information processed by the two account ends is ensured.
According to the embodiment of the present disclosure, the first information and the second information each include transaction identification information, and the transaction identification information is used for characterizing the transaction information in the request instruction, and further includes:
recording the first processing result information and the transaction identification information in a transaction log of the first account end;
and recording the second processing result information and the transaction identification information in a transaction log of the second account terminal.
According to an embodiment of the present disclosure, for example: the transaction identification information may be identified by a hash value of the transaction information in the request instruction as a key value. Under the condition that the first processing result information and the second processing result information are both successful in transaction, key, time, success > can be recorded in a transaction log of the first account end; recording < key, timestamp, success > in the transaction log of the second account terminal. The transaction log may include time information initiated by the transaction request command, so as to distinguish different transactions with the same transaction information. Different transactions with the same transaction information but different transaction time can also be distinguished by the transaction identification information and a hash algorithm.
According to the embodiment of the disclosure, the processing results and the transaction identification information of the two account ends are respectively recorded in the respective transaction logs, and whether the transaction is processed or not is identified through the transaction identification information, so that repeated processing or missed processing of the transaction can be effectively avoided.
According to an embodiment of the present disclosure, the transaction processing method applied to the distributed system further includes:
sending third information to the first account side under the condition that the first processing result information is not received within preset time, wherein the third information comprises first state information, transaction amount information, transaction identification information and repeated marks of the first account side;
and receiving third processing result information, wherein the third processing result information is obtained by changing balance information of the first account end according to the transaction amount information by the first account end under the condition that 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.
According to the embodiment of the disclosure, due to communication problems such as network timeout, the server does not receive the first processing result information fed back by the first account within the preset time, and may send third information to the first account again, for example: the third information may include the first status information that account a is present and normal and the balance is 50 ten thousand yuan, and the transaction amount information that account a deducts 10 ten thousand yuan, and further includes the transaction identification information key value and the repeat flag repeat.
According to the embodiment of the disclosure, when the first account end receives the third information with the repeat mark repeat, it is necessary to check whether the current state of the account a of the first account end is the same as the first state information of the account a in the third information, if so, then check whether a key value representing transaction identification information exists in a transaction log of the first account end, and if not, process the transaction, that is, change the balance information of the account a from 50 ten thousand to 40 ten thousand according to 10 ten thousand dollars of transaction amount information.
According to the embodiment of the disclosure, when the first account side receives the third information with the repeat mark repeat, if the current state of the first account side account a is different from that in the third information, the first account side account a is treated as a new transaction.
According to the embodiment of the disclosure, under the condition that 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, first processing result information recorded in the transaction log of the first account end is received.
According to an 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 account A of the first account end is the same as the first state information of the third information, and a key value representing the transaction identification information exists in the transaction log of the first account end. The transaction success and the processing result information recorded in the transaction log of the first account side, that is, the balance information of the account a is changed to 40 ten thousand, which are fed back to the server side.
According to the embodiment of the disclosure, by checking the state of the information with the repeated mark and the transaction identification information, the problem that the transaction information repeatedly sent by the server is repeatedly processed due to the fact that the processing result is fed back to the server overtime due to network communication and the like can be effectively avoided.
According to the embodiment of the disclosure, in the preset time, under the condition that the second processing result information is not received, fourth information is sent to the second account terminal, wherein the fourth information comprises transaction amount information, transaction identification information and a repeated mark;
and receiving fourth processing result information, wherein the fourth processing result information is obtained by the second account terminal changing the balance information of the second account terminal according to the transaction amount information under the condition that the transaction identification information does not exist in the transaction log of the second account terminal.
According to the embodiment of the disclosure, due to communication problems such as network timeout, the server does not receive the second processing result information fed back by the second account within the preset time, and may send the fourth information to the second account again, for example: the fourth information may include transaction amount information for 10 ten thousand dollars transferred to account B, and further include a transaction identification information key value and a repeat flag repeat.
According to the embodiment of the disclosure, when the second account receives the fourth information sent by the server, it needs to check whether a key value representing the transaction identification information exists in the transaction log of the second account, and if not, the balance of the account B is continuously changed, and the balance of the account B is changed from 5 ten thousands to 15 thousands.
According to the embodiment of the disclosure, if the key value representing the transaction identification information exists in the transaction log of the second account, which indicates that the transaction is processed, the second processing result information recorded in the transaction log may be fed back to the server.
According to the embodiment of the disclosure, by checking the information transaction identification information with the repeated mark, the situation that the transaction information repeatedly sent by the server is repeatedly processed due to the fact that the processing result is fed back to the server overtime due to network communication and the like can be effectively avoided.
According to the embodiment of the disclosure, when the second processing result information is the transaction failure, fifth information is sent to the first account terminal, wherein the fifth information comprises transaction amount information;
and receiving fifth processing result information, wherein the fifth processing result information is obtained by the first account according to the transaction amount information and the balance information of the first account.
According to an embodiment of the present disclosure, for example: the second processing result information is transaction failure, which generally occurs when the account B is cancelled in a short time, so that the posting transaction of the second account end cannot be completed. When the situation happens, the server side sends fifth information to the first account side and initiates a reverse transaction. The fifth information may include a transaction amount of 10 ten thousand dollars transferred to account a. The first account side changes the balance of account A from 40 ten thousand to 50 ten thousand yuan.
According to the embodiment of the disclosure, the server monitors the transaction processing result of the second account, performs reverse transaction on the transaction of which the account entry of the second account fails, and returns the money deducted from the corresponding account of the first account in time without influencing the execution of other transactions.
According to an embodiment of the present disclosure, the preset conditions include: the account states of the first account terminal and the second account terminal are normal; the account balance of the first account end is larger than the transaction amount in the transaction request instruction.
According to an embodiment of the present disclosure, for example: the server side can pay 10 ten thousand yuan for the account A to the account B after receiving the transaction request instruction, and the server side can determine whether to execute the transaction by acquiring the state information of the first account side and the second account side. If the state of the account A is normal and the state of the account B is logout, the preset condition is not met, and the service end does not execute the transaction processing operation in the embodiment of the disclosure. If the account a and the account B are normal, but the account balance of the account a is 5 ten thousand yuan and less than 10 ten thousand yuan, the preset condition is not satisfied, and the server does not execute the transaction processing operation in the embodiment of the present disclosure.
According to the embodiment of the disclosure, by setting the preset condition, the account state related to the transaction is inquired and judged before the transaction processing is executed, so that invalid transaction processing information sent by the server to the first account terminal or the second account terminal can be effectively reduced, and the timeliness of the transaction processing of the whole distributed system is improved.

Fig. 4 schematically shows an exemplary architecture of an application distributed system of a transaction processing method according to an embodiment of the present disclosure.
As shown in fig. 4, the distributed system 400 includes a client 401, a server 402, a first account 403, and a second account 404.
The client 401 initiates a transaction request from the first account-side 402 to the second account-side 403. After receiving the transaction request, the server 402 obtains status information of the first account 403 and the second account 404, where the status information of the first account 403 and the second account 404 may be va、vb。
Under the condition that the preset condition is met, the server 402 assembles transaction information according to the transaction request and records the transaction log, for example:<key，trade(va，vb)，timestamp>。
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 may be assembled into a transaction package:
<key：(P：xa←xa-x|va)∩(Q：xb←xb+x)>。
wherein, P represents a first account terminal, namely a payment account; q represents the second account side, i.e. the collection account.
The server 402 executes the transaction processing method applied to the distributed system of the embodiment of the present disclosure to process the transaction. For example: sending first information to a first account side: p: x is the number ofa←xa-x|va。
After receiving the transaction success information fed back by the first account terminal 403, the server terminal 402 sends second information to the second account terminal 404: q: x is the number ofb←xb+x。
After receiving the information on the successful transaction fed back by the second account 404, the server 402 feeds back the information on the successful transaction to the client 401. If the information of the transaction failure fed back by the second account side 404 is received, the server side 402 sends back the anti-transaction information (fifth information) to the first account side 403, and feeds back the processing result of the first account side to the client side 401.
According to the embodiment of the present disclosure, the transaction account information recorded by the first account side 403 and the second account side 404 is shown in the following table:

<key: (P: Success) U (Q: Success) U (R: by x)a←xa-x, credit: x is the number ofb←xb+x)>
The internal transitive account 604 processes the transaction amount information in the transaction information packet according to a final consistency algorithm to obtain the transaction account information of the internal transitive account 604 as shown in the following table:
Figure BDA0003460172420000161
if the server does not receive the information fed back by the internal transit user 604 within the preset time, the transaction information packet with the repeated mark is retransmitted to the internal transit user 604. When the internal transitive user 604 receives the transaction information packet with the repeated mark, the transaction log is queried, and if the key value in the transaction information packet exists in the transaction log, the result is fed back to the server 601 according to the transaction log. And if the key value in the transaction information packet does not exist in the transaction log, processing according to a final consistency algorithm.
According to the embodiment of the disclosure, the invention can provide an adaptive processing scheme for the scenes of 'one borrow and one credit', 'one borrow and multiple credits', 'multiple borrow and one credit' in the transfer transaction. For example, in the scenario of "one loan and multiple credits", the second information may be sent to the collection account concurrently after the single-sided transaction at the payment account.
