Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a hotspot account accounting method and system. Background Art

[0002] As payment demands continue to grow, more and more users are gradually using online payments, and the requirements for the stability and reliability of payment systems are becoming increasingly higher. The response rate of the payment system is directly related to user satisfaction with payment products.

[0003] In this context, for accounting needs in certain specific scenarios, such as high concurrency scenarios for a single account: batch deductions, salary payments, etc., users also require extremely high response rates. Due to the characteristics of the scenarios, the accounting system needs to lock the balance for each transaction, and a large number of lock requests are queued, which increases the overall time consumption. In serious cases, it even affects the entire application cluster or database abnormalities, causing large-scale failures. For such scenarios, the usual practice is to adopt flow limiting measures to reject data that exceeds the flow range. Although the overall response rate is improved and the system security is guaranteed, the success rate is lost, affecting the user experience. At present, the main defect is that the database pressure caused by the high concurrency of the accounting system may slow down the database as a whole, affecting other businesses and even affecting other database instances in the same physical machine cluster. The large number of reading and writing balances in the accounting operation to lock the table will increase the overall transaction time consumption, poor user experience, and it is very easy to exceed the assessment threshold of transaction time consumption of financial institutions such as China UnionPay. The overall success rate is reduced due to flow limiting technology, which leads to new user experience problems. Summary of the invention

[0004] In order to solve at least one of the problems mentioned in the above background technology, the present invention proposes a hotspot account accounting method and system, which solves the database performance bottleneck problem caused by frequent reading and writing of lock balances of hotspot accounts without affecting the transaction success rate.

[0005] To achieve the above objectives, the technical solutions adopted by the present invention include:

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0042] The first aspect of the present invention relates to a process of steps as follows Figure 1 The hotspot account accounting method shown includes:

[0043] Set asynchronous accounting conditions;

[0044] Specifically, in the embodiment of the present application, setting the asynchronous accounting conditions includes configuring a whitelist and setting a weight ratio. According to risk prevention and control, the asynchronous accounting whitelist is pre-configured to allow only small transactions (the maximum amount is configurable); and the maximum concurrency (number of token buckets) during asynchronous accounting is set.

[0045] The database configuration is used and saved synchronously in redis. The format example is as follows:

[0046] Key: System Number: Business Scenario: Account Number

[0047] Value:{"open":"1","maxAmtLimit":"20000.00","proportion":"0.7","rate":"30"}

[0048] The following table shows examples of field values:

[0049]

[0050] In this embodiment, necessary parameter, technical and business verification is required. The accounting system is called to query the legality, status and account balance information of the requested accounting account.

[0051] Obtaining an accounting request, and determining whether the accounting request satisfies an asynchronous accounting condition;

[0052] Specifically, in the embodiment of the present application, it is determined whether the account corresponding to the accounting request is in the whitelist;

[0053] If the account corresponding to the accounting request is in the whitelist, determining whether the product of the account balance of the account and the weight ratio is greater than the sum of the total amount of the cache queue and the current transaction amount;

[0054] If the product of the account balance of the account and the weight ratio is greater than the sum of the total amount of the cache queue and the current transaction amount, the accounting request meets the asynchronous accounting condition; otherwise, synchronous accounting is performed.

[0055] For example, 100 yuan has been cached, the transaction amount is 50 yuan, the account balance is 200 yuan, and the weight ratio is set to 0.7; then 100+50<200*0.7 is not true, the condition is not met, and the asynchronous accounting process is exited and synchronous accounting is used; if the above conditions set the weight ratio to 0.8, then 100+50<200*0.8 is true, and asynchronous accounting is performed. The calculation logic uses redis Lua script to ensure atomic operations.

[0056] Redis data structure example:

[0057] Key: System number: Transaction scenario: Transaction date: Account number

[0058] Value: cache accumulated amount

[0059] If the accounting request meets the asynchronous accounting conditions, the transaction amount is accumulated and stored in a cache queue, such as redis;

[0060] When the asynchronous accounting conditions are not met, synchronous accounting is performed directly and the accounting results are returned to the upstream system.

[0061] Obtain information corresponding to the accounting request, register an asynchronous accounting flow table, and obtain a registration result;

[0062] Determine whether the registration result is successful, and if the registration result is successful, write the information into a message queue, such as an MQ queue;

[0063] If the registration fails, the synchronous accounting will be performed directly and the accounting results will be returned to the upstream system.

[0064] Asynchronous accounting aims to reduce peak loads and fill valleys, and it is necessary to use necessary flow limiting methods, and common flow limiting methods generally include leaky bucket algorithm, token bucket algorithm, sliding window algorithm, etc. The embodiment of the present invention adopts the token bucket algorithm.

[0065] The payment system reads the information in the message queue and applies for a token;

[0066] Determine whether the token application is successful, and if so, initiate the accounting request to perform synchronous accounting;

[0067] The transaction amount in the cache queue is deducted, the information consumption is successful, and the information in the message queue is deleted.

[0068] Specifically, in an embodiment of the present invention, each application in the payment system is a consumer, and reads information from the MQ queue at regular intervals. When the information is read successfully, apply for a token from the token bucket (such as setting the number of tokens per second in the token bucket to 10); when there is too much information in the MQ queue, the application fails to apply for a token, then the current consumption is abandoned, the information is read again, the information is not discarded, and the consumption is continued after the next token application. If the token application is successful, the accounting system is called to complete the accounting. The total amount of the MQ queue cache is deducted, and its value is the current transaction amount. Return consumption success, and delete the information in the message queue.

[0069] In some embodiments, when the MQ queue middleware fails, the database downgrade process is used. Specifically, the message is written to the database before the information is written to the MQ queue; a scheduled task is set to regularly check and process failed transactions. When the number of failures to write the same information to the message queue exceeds a threshold, for example, 3 times, the database downgrade process is used to automatically turn off the overall asynchronous accounting switch, print key logs, monitor alarms, notify the operation and maintenance personnel to find out, and reset the switch after manual confirmation of recovery.

[0070] In some embodiments, when the redis middleware fails, for example, when information consumption fails, it waits for the next time to continue consumption. At the same time, in order to prevent the message content from being incorrect or other problems from causing the message to be consumed unsuccessfully, the maximum number of times the information is consumed is set. For example, the message is set to be consumed at most three times. If it is still unsuccessful, the database is downgraded to ensure that the information can eventually be consumed.

[0071] For another example, the amount in the cache queue cannot be deducted, which is equivalent to a slight increase in the weight. The overall impact is negligible and no special processing is required.

[0072] Another aspect of the present invention also relates to a hotspot account accounting method system, the structure of which is as follows: Figure 2 As shown, including:

[0073] Setting module, used to set asynchronous accounting conditions;

[0074] A first judgment module is used to obtain an accounting request and judge whether the accounting request meets the asynchronous accounting condition; if the accounting request meets the asynchronous accounting condition, the transaction amount is accumulated and stored in the cache queue;

[0075] The second judgment module is used to obtain information corresponding to the accounting request, register the asynchronous accounting flow table, and obtain the registration result; determine whether the registration result is successful, and if the registration result is successful, write the information into the message queue;

[0076] The third judgment module is used for the payment system to read the information in the message queue and apply for a token; determine whether the token application is successful, and if the token application is successful, initiate the accounting request for synchronous accounting;

[0077] The processing module is used to deduct the transaction amount in the cache queue, and if the information is consumed successfully, delete the information in the message queue.
