In this embodiment, the specific application scenarios may be:
after a user carries out transaction delegation in a transaction system, the transaction system needs to process a great number of business rules when processing the transaction delegation, and an internal database is used as an operation object, so that SQL statements need to be analyzed and the SQL statements run in a multi-thread mode, and the overhead of thread switching cannot be avoided, so that the data transmission time is prolonged.
The method comprises the following specific steps:
step S100, transaction entrusting information of a user is obtained;
in this embodiment, the transaction system acceleration method is applied to a transaction system acceleration device.
In this embodiment, the user is a user who participates in financial transaction using a transaction system, the transaction system is an application program for processing financial transaction, the transaction commission information is information generated by initiating financial transaction commission for the user, and the information includes information of transaction type, amount, fee and the like, wherein the transaction type is a transaction mode supported by the system, and includes stocks, funds, futures and the like.
In this embodiment, a user initiates a transaction delegation request to a transaction system at a terminal, where the transaction delegation request includes transaction delegation information of the user, and a manner of acquiring the transaction delegation information of the user is to receive the transaction delegation information sent by the user terminal.
Before the step of acquiring the transaction delegation information of the user in the step S100, the method includes the following steps a100-a200:
step A100, acquiring user data;
in this embodiment, the user data is behavior data of the user in the transaction system, and includes personal information data submitted by the user when creating a transaction account, transaction behavior data after generating a transaction, account asset data, and the like, and the manner in which the device acquires the user data includes receiving data information uploaded by the user, storing transaction data information of the user in the transaction system and data information preconfigured by the device, and storing the user data in a database of the transaction system.
Step A200, determining legal user data in the user data, and loading the legal user data to a shared memory.
In this embodiment, legal user data in the obtained user data is determined, and only the legal user data is loaded to the shared memory.
Specifically, the step a200 includes the following steps a210 to a230:
step A210, screening the user data based on a preset first rule to obtain a screening result;
in this embodiment, the first rule determination process is a preset account rule check, that is, it is determined whether an account where the user data is located is legal according to the transaction operation rule, the first rule determination process includes an account rule check and a security rule check, the account rule check includes checking account validity and checking customer transaction service authority, and the security rule check is to check whether the account is a card stopping security. And loading the checked user data into a shared memory, wherein the shared memory is a large-capacity memory which can be accessed by different Central Processing Units (CPUs) in a computer system of a multiprocessor, and the data in the shared memory is stored by adopting a hash table, so that the time complexity of inquiring or modifying the data is constant time, the efficiency of inquiring the corresponding user data is accelerated, and the time delay of data transmission is reduced.
In this embodiment, the apparatus performs a pre-classification process on the user data based on a preset first rule, where the pre-classification process includes performing account information classification, transaction authority classification, security information classification, and the like on the user data, so as to accelerate the determination and screening of the first rule.
In this embodiment, the user data is screened based on a preset first rule, and the user data is screened through a screening model including a first rule screening manner, where the screening model is obtained by iteratively training a model to be trained based on a user data sample and a screening result label of the user data sample, and is screened in a model manner, so as to accelerate the determination efficiency of the user data.
Step A220, determining the legal user data and the illegal user data based on the screening result;
in this embodiment, when the transaction system executes an activation operation, the user data in the database is subjected to judgment and screening of some service rules, that is, a preset first rule, where the first rule includes account rule check, security rule check, and the like, and it is judged whether the user data meets a transaction operation rule, if yes, the user data is legal user data, and if not, the user data is determined to be illegal user data.
Step a230, removing the illegal user data, loading the legal user data to a shared memory, and sorting the legal user data in the shared memory.
In this embodiment, data that does not meet the rules is eliminated, so that the judgment of the business rules is reduced. In this embodiment, the determination of other business rules, such as wind control rules, may also be reduced.
In this embodiment, legal user data is loaded into a shared memory, and the legal user data is sorted in the shared memory so that when the user data is positioned, the corresponding user data is quickly positioned according to a binary search method, thereby reducing data transmission delay.
Step S200, positioning corresponding user data in a shared memory based on the transaction entrustment information, wherein the user data is preloaded in the shared memory;
in this embodiment, the device receives the transaction request message initiated by the user, and first finds the corresponding user data from the shared memory, that is, locates the corresponding user data in the shared memory. If no corresponding user data exists in the shared memory, that is, the user account initiating the transaction is an illegal account, the user terminal prompts that the user is the illegal account, and the transaction cannot be initiated.
Specifically, the step S200 includes the following steps S210 to S220:
step S210, determining the element size of the keyword in the transaction entrusting information;
in this embodiment, the data in the shared memory is stored in a hash table, where the hash table is also a hash table, and is a data structure capable of directly accessing a specific corresponding value through a value of a given key. The key is mapped to a location in a table to directly access the record to speed up access. Usually, we refer to this Key as Key and the corresponding record as Value, so we can also say that the Key accesses a mapping table to obtain the address of Value. This mapping table is also called hash function or hash function, and the array storing records is called hash table.
In this embodiment, based on the transaction entrusting information, a keyword in the transaction entrusting information is obtained according to a preset keyword determination rule, and the keyword obtains an element size of the keyword according to a preset assignment.
Step S220, comparing the sizes of the elements of the keyword with the sizes of the elements in the shared memory in a binary cycle until the element with the same size as the element of the keyword in the shared memory is located, where the element is user data corresponding to the transaction delegation information in the shared memory.
In this embodiment, according to a binary search method, locating user data corresponding to the transaction delegation information in the shared memory, where the data arrangement of the shared memory is sequentially arranged, for example, taking an ascending sequence number as an example, comparing the size of an element with an element at a middle position in the sequence, and if the size is larger than the element at the middle position, continuing to perform binary search in the sequence at the second half; if smaller than the element in the middle position, the comparison is made in the first half of the series; if equal, the position of the element is found. The length of the series for each comparison will be half that of the previous series until an equal element is found or eventually no element to be found is found.
In this embodiment, a space-to-time logical judgment method is adopted in the shared memory, so that the judgment of the complex conditional statement can be completed in the shortest time, and the corresponding user data in the shared memory is located according to the keyword, thereby accelerating the efficiency of querying the corresponding user data and reducing the time delay of data transmission.
Step S300, based on the transaction entrusting information and the user data, judging whether the transaction is legal;
in this embodiment, the apparatus determines whether the transaction initiated by the user this time is legal according to the transaction delegation information and the user data.
Specifically, the step S300 includes the following steps S310 to S320:
step S310, judging whether the user data is legal;
in this embodiment, the device determines whether the user data is legal by determining whether the user data is located in the shared memory, if the shared memory contains the corresponding user data, the user data is legal, and if the user data is not located, the user data is illegal, and the user terminal prompts the user that the user is an illegal account and a transaction cannot be initiated.
Step S320, if the user data is legal, based on a preset second rule, determining the transaction delegation information and the user data, and determining whether the transaction is legal.
In this embodiment, the preset second rule is a preset service rule check, that is, whether the transaction order information and the user data are legal is determined according to a transaction operation rule, where the second rule determination process includes a variety rule check, a behavior rule check, an interface rule check, and the like, where the variety rule check is rise and fall control, and the behavior rule check is to check whether to allow repeat delegation; checking for stock sales, etc., and the interface rule checks to check whether the API interface of the user is normal.
In this embodiment, the trading commission information further includes security code information, that is, code information of a security to be traded by the user, where the security code is composed of 6 digits, and according to the check of the second rule, it is checked whether the security code included in the trading commission information meets the trading condition, and according to the security code in the trading commission information, as an array subscript, by means of a storage pointer, it locates corresponding security data information in the shared memory, and according to the security data information, it is checked whether the user meets the trading condition.
In this embodiment, since the first rule determining process completes the check before the transaction occurs, the check does not need to be performed again after the transaction occurs, so as to speed up the efficiency of the service rule check and reduce the time delay of data transmission.
And step S400, if the transaction is legal, generating a transaction order and sending the transaction order to an inventory gateway of the exchange.
In this embodiment, if the device determines that the transaction initiated by the user is legal, a corresponding transaction order is generated, and the transaction order is sent to an inventory gateway of the exchange. The transaction order commission declaration is directly sent to the exchange declaration gateway, and the embedded declaration is not needed any more, so that the time delay of data transmission is reduced.
After the step of sending the trade order to the listing gateway of the exchange at step S400, the method comprises the following step B100:
and step B100, receiving a transaction confirmation message sent by the exchange, and sending the transaction confirmation message to the user, wherein the thread for sending the transaction confirmation message and the thread for sending the transaction order to the exchange are the same thread.
In the embodiment, a single-thread working mode is adopted, the transaction entrusting request of the user and the return processing of the exchange both use the same thread, the overhead caused by multi-thread switching is avoided, only the minimum amount of locking and unlocking operations are needed, and the locks are only used for a user state space, so that the time delay of data transmission is reduced.
In this embodiment, the device performs interaction between data by using a network library, where the network library uses a low latency network adapter technology, where the low latency network adapter technology may be an onload technology and a TCPDirect technology of a solarfar network adapter, or a rdma technology of a meldonox network adapter, and further reduces latency of data transmission.
In this embodiment, referring to fig. 4, when the apparatus executes the activation operation, data in the database is loaded into the shared memory, and in the process, the first rule determination processing is performed to remove data that does not meet the rule, so that the soft acceleration process can reduce the determination of the service rule. The device can directly operate the data in the shared memory without using a memory database, thereby reducing the analysis of SQL statements. The data in the shared memory is stored by adopting a hash table, so that the time complexity of inquiring or modifying the data is constant time; some logic judgment also adopts a space time-changing strategy, so that the judgment of complex conditional statements can be completed in the shortest time. The soft acceleration process adopts a single-thread working mode, the client entrusts requests and the return processing of the exchange, the same thread is used, and the expenditure caused by multi-thread switching can be avoided. The soft acceleration exclusive exchange report gateway is separated from the original extremely fast process.
