Description
Technical Field
The application relates to a method for detecting accounting of a hotspot account.
Background
Generally, in a transaction system of a bank or a third-party payment mechanism, when a large-scale fund change is concentrated on a single account (such as a commission account) at a certain moment, the account needs to be controlled to ensure the accuracy of the account balance change. Generally, the accounting processing mode of such accounts (hereinafter collectively referred to as hotspot accounts) is controlled by pessimistic locks or optimistic locks of databases. However, the frequent addition and subtraction of the balance of the hotspot account can cause the database to perform frequent I/O operations, thereby reducing the I/O reading and writing speed of the database, finally affecting the slow accounting of the hotspot account, and even causing the serious consequence that the link of the whole transaction system is hung up.
Many companies and technical dawners have proposed various solutions for hot accounts, which are commonly found in the following means:
1) hardware upgrade. The performance of a database server is enhanced to meet the current service scene by improving the configuration of hardware;
2) memory balance. Loading the balance of the account from the database to the memory, recording running water during transaction, adding or subtracting the balance of the account from the memory, and then refreshing the balance of the memory to the database at regular time;
3) buffering accounting. The real-time synchronous accounting behavior is converted into asynchronization so as to achieve an accounting means of balance between accounting instantaneity and system stability, namely peak clipping and valley filling;
4) split sub-account. The balance of a single account is split into a plurality of sub-accounts, so that the operation frequency of the single account is distributed to the plurality of sub-accounts, and the flow sharing is achieved.
Although there are many means for solving the hot account, the factors influencing the account billing accuracy are mainly determined by the following aspects:
1) performance limitations of stand-alone machines (no matter how powerful the machine has its performance bottleneck).
2) Sudden downtime, outage, application crash of server (various overwhelming emergencies)
3) Data delay due to high concurrency (high concurrency easily leads to resource exhaustion and slow system operation).
4) Depletion of sub-account balances results in account balances sufficient to cause instantaneous bulk transaction failures, and how balances are allocated when hot accounts are recharged.
5) Billing delays when a hotspot account becomes a non-hotspot account result in reduced user satisfaction.
Since the various problems described above exist in the transaction process of the hot account, the hot account processing becomes extremely complicated when all the factors described above must be considered together in the actual implementation process.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.
According to an embodiment of the application, a method for hotspot account billing is provided. FIG. 1 shows a hotspot account billing flow diagram of a method of hotspot account billing according to an embodiment of the application. Referring to fig. 1, in the method for billing a hotspot account of the present invention, after receiving a billing request, if the account is a hotspot account, the hotspot account type of the account is determined; entering the accounting of a hotspot accounting account or entering the accounting of a hotspot accounting account according to the hotspot account type; and if the total balance in the hot spot account is insufficient, recharging each sub-account according to the balance of each sub-account of the hot spot account.
According to the technical scheme, the concurrent processing capacity of the hot spot account in the transaction system can be effectively improved, and meanwhile, the real-time performance and the accuracy of the bookkeeping are guaranteed.
The hotspot account accounting technology of the invention is applied to the accounting system application software, and effectively improves the concurrent processing capacity of hotspot accounts (such as commission accounts) in the transaction system (greatly improved from 200TPS (system throughput) supported by the original system under the condition of the same hardware resource configuration, and the maximum can reach 2000 TPS).
According to one embodiment of the invention, as shown in fig. 2, a hotspot account billing process flow of the invention is shown.
1) Division of hotspot accounts
First, it is determined whether an account is a hotspot account 201. How to determine if an account is a hotspot account? Different services and different systems have different division standards, and we have carried out preliminary analysis according to the current transaction situation to discover that: one type of account (e.g., a moist account of a large merchant) is characterized by frequent balance increases, while another type of account (e.g., a flat account of a large merchant) is characterized by frequent balance decreases. Meanwhile, the internal system is also investigated and shown: with the same resource allocation, it is found that some of the systems with high service complexity can only support dozens of TPS, while other systems (such as systems with high service resolution) can support hundreds or even thousands of TPS. Combining the analysis and the construction condition of the account system, the method can finally determine that the account entry and the account exit of the transaction TPS higher than 200 and the accumulated days exceed 10 minutes and are respectively defined as a hot spot account entry account and a hot spot account exit.
2) Accounting 202 of hotspot posting accounts
After the system receives the accounting request of the business system, when the account is judged to be a hotspot accounting account, the accounting request information and the original accounting flow are inserted into the database 203, the details of the funds to be summarized are recorded and enter the buffer table 204, and the result is synchronously returned. And sequencing the batch processing process according to the transaction occurrence time at regular time, updating the post balance 205 in the original financial affairs flow water one by one, summarizing multiple transaction amounts, and refreshing the account balance once.
3) Accounting 206 of hotspot billed accounts
Firstly, the balance of the main account is averagely distributed to the sub-accounts, and the sub-accounts containing the balance and the balance information are recorded in a cache 207 (the current system adopts Redis as a cache system) for fast searching for tradable sub-accounts in subsequent transactions (the balance average distribution strategy is that if the total amount of the main account A is less than a certain threshold (for example, 1000), the total balance is directly distributed to one sub-account A1 because of too little total balance, otherwise, the balance of the main account A is averagely distributed, balances are distributed to the sub-accounts A1 … An in turn, when the residual balance of the main account is less than the threshold, the distribution is finished after the residual balance is directly distributed to one sub-account, and at this time, the number of the sub-accounts with the balance may be less than n).
During transaction, the algorithm of the invention can obtain a sub-account list 208 meeting the conditions according to the transaction amount (because the balance of a single sub-account may not be enough), sort the sub-accounts first and then lock the sub-accounts 209 (the purpose of sorting is to prevent deadlock caused by mutual waiting of resources due to concurrency), and if the balance of the sub-accounts is enough under normal conditions, directly update the balance of the sub-accounts and record the running water of the sub-accounts and then unlock the sub-accounts; when the total balance of the sub-accounts acquired at this time is insufficient 210 due to large concurrency after the account is locked, an unlocking retry mechanism is adopted until the balance of all accounts is insufficient, so that the success rate of transaction is ensured to the maximum extent. Meanwhile, in the period, if the account is changed from the hotspot to the common account 211, the invention can process the transaction in time according to the common account mode and ensure the real-time performance and accuracy of balance updating.
The transaction flow is analyzed in detail below according to two scenario models:
the first scenario is a normal transaction model:
current account A, sub-account A1(500), A2(600), A3(800)
Transaction 1: the amount of occurrence is 1000, and the sub-accounts meeting the conditions are selected by the algorithm to be A2 and A1
Transaction 1: after sorting the sub-account numbers, according to the sequence of A1A2, locking the accounts, deducting the balance A1(0), A2(100)
Transaction 1: unlocking the sub-account A1A2, wherein the remaining amount of the sub-account is as follows: a2(100), A3(800)
Transaction 1: sub-account a1 is removed from the cache so that the next transaction is not being selected.
The second scenario is a retriable transaction model:
current account A, sub-account A1(500), A2(600), A3(800)
Transaction 1: the amount of occurrence is 1000, and the sub-accounts meeting the conditions are selected by the algorithm to be A2 and A1
Concurrent transaction 2: the amount 200 occurs, during the transaction the sub-account A1 is selected to be deducted to complete the transaction, A1(300)
The remaining amount of the sub-account of the account A after the transaction 2 is completed is as follows: a1(300), A2(600), A3(800)
Transaction 1: after sorting the sub-account numbers, the account is locked according to the sequence of A1A2, and the total balance is found to be insufficient
Transaction 1: unlocking the sub-account A1A2, and selecting the sub-accounts meeting the conditions A2, A1 and A3 again through the algorithm
Transaction 1: after the sub-account numbers are sorted, according to the sequence of A1A2A3, the remaining sum of the sub-accounts after balance deduction is A1(0), A2(0) and A3(700)
Transaction 1: the sub-account A1a2 is removed from the cache so that the next transaction is not selected.
After the batch process is initiated 212, the post balance 213 is periodically and chronologically summarized from the to-be-summarized fund detail.
The following is an embodiment of the top-up balance allocation procedure of the hotspot billed account of the present invention in conjunction with fig. 3.
Example (b):
recharge model
The recharge amount is 20000
Sub-account balances for current account A1(0), A2(600), A3(10600), (where a balance of 0 indicates that the sub-account is unavailable)
Top-up start (301 in fig. 3):
total recharge amount + sub-account balances SUM _ AMT (31200) (302 in FIG. 3)
Calculating average balance AVG _ AMT ═ SUM _ AMT/3(10400) (303 in fig. 3)
Obtaining the sub-account list needing to be charged as A1, A2
Sub-accounts are recharged in turn (at 304 in fig. 3):
after the first sub-account is charged, a1(10400), a2(600), A3(10600), and the a1 sub-account is activated as available; at this time, the remaining amount of the recharging money is 20000-minus 10400-minus 9600;
after the second sub-account is charged, a1(10400), a2(10200), A3 (10600); at this time, the remaining amount of the recharge amount is 0;
thus, the remaining charge amount is 0, and the charge is completed.
In summary, in a general case, the account system is the most core system of a bank or a payment company, and once the account system goes down, the transaction is completely stopped, which may cause adverse effects on user experience, and thus may seriously affect the development of company business. The invention processes different service accounts in the aspects of system deployment, storage deployment and the like in a unitized way, and realizes an account system with one service being down and other services not being affected.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
