Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical terms used in the examples of the present invention are defined and explained below:
1. time complexity: the temporal complexity of the algorithm is a function that qualitatively describes the runtime of the algorithm. This is a function of the length of the string representing the algorithm input value. The time complexity is often represented by a large O symbol, describing the relationship between the time used by the algorithm and the size of the executed data.
2. Redis data Structure: string, Hash, List are all data storage structures provided by the Redis API.
3. Redis Lua: the Redis embedded scripting language can combine certain business logic. The Lua script has exclusivity, namely, the Lua script does not accept and kill any Redis operation request outside the script during the execution period, and the atomicity of the Redis data change executed in the Lua script can be ensured.
4. Spring: spring is a lightweight open-source framework in the field of Java EE programming, and is an application-type framework for solving the complexity in enterprise-level programming development and realizing agile development. Currently, the mainstream Java applications are realized by using a Spring framework or by using Spring boot, Spring cloud and the like derived from the Spring framework.
The time wheel technology is an implementation mechanism for checking a low-precision timer (the minimum scale is 1Hz, the second level) in the Linux, and is also a timer with optimal time complexity. Most delay algorithms are based on a time wheel technology, the time wheel technology is a scheduling model for efficiently utilizing thread resources to perform batch scheduling, large batches of scheduling tasks are all bound to the same scheduler, the scheduler is used for managing, triggering and running all the tasks, various delay tasks, periodic tasks, notification tasks and the like can be efficiently managed, and the time complexity is O (1) under a specific condition.
In the asynchronous communication field of software architecture design, a time round technique is generally adopted when time precision requires a second level, massive tasks are added, requirements on a task execution sequence with similar time are not strict, and requirements that a task issuing party and a task executing party are not directly connected are met.
In the prior art, when a plurality of partners exist on an internet loan platform (simply referred to as an internet loan platform), rules of a plurality of third party interfaces are processed when being called during a single transaction. When the existing credit granting application flow carries out service arrangement processing according to step splitting, all steps are mainly processed in series or certain strategies are carried out for parallel processing result collection through a thread pool in a single application. The main problems that exist are: the whole transaction link time is long, the transaction time of one credit authorization usually needs dozens of seconds to minutes, each credit authorization transaction needs to occupy a thread to wait for a return result, the concurrence of each application is small, and the needed CPU resource is high; the asynchronous processing of the incoming and outgoing message queues requires additional hardware resources, and the retransmission/idempotent processing of each message queue is required during use, so that the processing efficiency of transaction is low.
In order to solve the technical problem, an embodiment of the present invention provides a method for processing a credit application, and a detailed description is provided below for a solution of the embodiment of the present invention.
Fig. 1 is a flowchart illustrating a method for processing a trust application according to an embodiment of the present invention. As shown in fig. 1, the method mainly comprises the following steps:
and S101, receiving a credit granting application, and determining a task corresponding to the credit granting application in a target database based on the credit granting application and the global time wheel.
The method provided by the embodiment of the invention can be applied to a server, the server can be a server of a network credit platform or a financial platform, and the local time wheel can be arranged in local application, such as Java application; the global time wheel can be time wheel related data stored based on a Redis database, Redis is used for storing the time wheel related data, equivalently global variables are carried, and the related Redis data structure design can meet the following requirements: (1) the task list for each time slice should be retrievable at O (1) time complexity, which is a function that qualitatively describes the run time of the algorithm; (2) the task list is a two-way linked list with the complexity of O (1) in operation time, and is convenient for insertion and extraction; (3) the operation of taking out the task can be balanced in load; (4) the tasks which are executed for multiple times can be provided with parameters so as to facilitate quick operation; (5) unpredictable large-scale operations are avoided from blocking the Redis main thread.
The server receives a credit application, which can be sent by an external system such as a partner or a business party, and a credit platform (which can be located in the server) receives the application and transmits information such as user information, identity cards, face recognition images, contacts, bank card information, equipment information and the like to the credit platform. And the credit granting platform performs database dropping on all the information, performs verification such as blacklist, relation list, anti-money laundering list and the like, performs anti-fraud check, credit investigation and risk approval, and transmits approval results to the partner in real time.
In some embodiments, determining a task corresponding to a trust application in a target database based on the trust application and a global time wheel may include the following steps:
creating a task detail of the credit application based on the credit application; creating a task corresponding to the credit granting application according to the task detail of the credit granting application; establishing an incidence relation between the task detail of the credit granting application and the task corresponding to the credit granting application through a global time wheel; and determining a task corresponding to the credit granting application in the target database according to the association relation.
Specifically, the credit application may include basic information of a service party or a partner, such as user information, an identity card, a face recognition image, a contact, bank card information, device information, and the like, and according to the information included in the credit application, a task detail that needs to be subjected to information approval is determined, such as verification of a blacklist, a relation list, an anti-money laundering list, and the like, anti-fraud verification, credit investigation inquiry, risk approval, and the like, the task detail is created according to the credit application, an association relationship is established through a global time wheel according to the created task detail and a task corresponding to the credit application, and according to the established association relationship, a task corresponding to the credit application may be determined in a task list in a target database.
In some embodiments, the method for creating task details of a trusted application based on the trusted application may include: determining the content of the credit application request access; establishing a verification rule of the credit granting application according to the determined content of the access request of the credit granting application; and generating a task detail of the trust application based on the verification rule.
Specifically, firstly, the content requested to be accessed by the credit granting application, such as a personal loan blacklist database, a related public service, a matching related person list, an anti-money laundering service and the like, is determined, and according to the content requested to be accessed in the credit granting application, a check rule for accessing the content is created, wherein the check rule may include an access sequence of each content, and may also be an access rule, for example, the check in the blacklist is failed, the check in the matching related person list is passed, and a specific access rule may be set according to the actual requirements of the user. The task details of the trust application are generated according to the check rule, that is, the task details may include specific task contents, which is described above by way of example only, and the content requested to be accessed may be adjusted according to the actual business requirements of the business party or the partner.
In some embodiments, creating a verification rule of the trusted application according to the determined content requested to be accessed by the trusted application may include: determining a syndrome rule included in a verification rule of the credit application according to the determined content of the access request of the credit application; wherein, the syndrome rules comprise the execution rules of each syndrome rule; and establishing the verification rule of the credit granting application based on the execution rule of each verification sub-rule.
For example, the check rule for the credit application may include a syndrome rule for each requested access content, the syndrome rule includes an execution rule of each syndrome rule, and the syndrome rule may be represented by a sequence parameter, such as a step number, parallel or serial, for example, a check sequence of each access content, and the check rule for the credit application is created based on the execution rule of each syndrome rule.
Further, creating the verification rule of the trust application based on the execution rule of each syndrome rule may include: judging whether an execution step dependency relationship exists between any syndrome rule and any other syndrome rule or not aiming at any syndrome rule; when the execution step dependency relationship exists, determining that the execution rule of any syndrome rule is serial execution; when the execution step dependency relationship does not exist, determining that the execution rule of any syndrome rule is executed in parallel; and creating a verification rule of the credit granting application according to the determination result of the execution rule.
Specifically, the check rule of the trust application may include a plurality of check sub-rules, and each check sub-rule may have a step dependency relationship, that is, the check sub-rules having the step dependency relationship need to be executed serially, which has a certain execution sequence requirement, and the check sub-rules having no step dependency relationship may be executed in parallel, and each check sub-rule does not affect each other, and may be executed simultaneously.
After creating the verification rule of the trust application based on the execution rule of each syndrome rule, the method may further include: storing the verification rule of the credit granting application in a task list of the global time wheel; and acquiring the task detail of the credit granting application based on the task list. In the embodiment of the invention, the verification rule of the credit granting application is stored in the task list of the global time wheel, and the task detail of the credit granting application is obtained according to the verification rule of the credit granting application stored in the task list and each sub-verification rule.
It should be noted that, the task details of the trust application are obtained in the target database in a Lua script mode; the global time wheel stores a task List via a List data structure. The Lua script is a script language embedded in Redis and can be combined with certain service logic. The Lua script has exclusivity, any Redis operation request except the Lua script is not accepted during the execution of the Lua script, and the atomicity of the Redis data change executed in the Lua script can be ensured. The Lua script mode can ensure that the taken tasks cannot be taken out again by other applications, thereby avoiding repeated access in the same time and realizing load balancing.
Taking Redis to store time wheel data as an example, the Redis stores a current pointer and a task List of a time wheel, the specific Redis can store the task List by using a List data structure, when a task is added to the task List in the Redis, a single task can be added by an hmset command to ensure atomicity, and the number of fields of the task is limited to ensure that the hmset is not blocked. When the number of steps and the step dependence order in the verification rule of the trust application are determined, a next field is added in the Hash of the task to point to the taskKey of the next task, namely, a linked list of another dimension is formed outside the task list. And the Lua script checks that when the execution time of the task returns to zero, if a next task exists, the task is put into a global time wheel according to a rule, and then the serial mechanism of the task can be realized.
Meanwhile, a tradeId field is added in the Hash of the task, the tradeId field can be used for aggregating parallel tasks of the same service Id, the execution result of the task is written into a set X according to a key value key spliced by the service Id (the execution result of the task is specifically designed according to the service and can be set data structures of Redis such as Hash, List, Zset and the like), and data preparation of the parallel result can be realized. Based on the monitoring of the set X, the aggregation of the parallel results is further realized.

And step S104, when the local time wheel monitors that the execution result of the task meets the processing condition of the credit granting application, acquiring the execution result of the task in the target database and feeding the execution result back to the sending end of the credit granting application.
When the execution result of the task meets the processing condition of the credit granting application, for example, when all the checking sub-rules are passed, namely the credit granting application is successful, the execution result of the task in the global time wheel is obtained in the target database and fed back to the sending end of the credit granting application, so as to inform the sending end of successful credit granting application.
In a specific embodiment, the method provided in the embodiment of the present invention may further include: recording the execution result of the task meeting the processing condition of the credit granting application; and sending the execution result to a sending end of the credit granting application.

In a specific embodiment, the method provided in the embodiment of the present invention may further include: when the local time wheel monitors that the execution result of the task does not meet the processing condition of the credit granting application, acquiring the task corresponding to the credit granting application; judging whether the execution of the task is completed; when the task is not executed, synchronizing the task corresponding to the credit granting application to a local time wheel, and executing the task in the local time wheel; and when the task is executed, recording the execution result of the task which does not meet the processing condition of the credit granting application and sending the execution result to the sending end of the credit granting application. When the local time wheel monitors that the execution result of the task does not meet the processing condition of the credit granting application, the task corresponding to the credit granting application is obtained again, and whether the task is executed and completed is judged, for example, whether the details of the task included in the task are executed and completed is specifically judged; when the task is not executed, synchronizing the task corresponding to the credit application to a local time wheel, executing the task in the local time wheel, and synchronizing the execution result to a global time wheel or recording the execution result in the local time wheel; when the task is executed, recording the execution result of the task which does not meet the processing condition of the credit granting application and sending the execution result to the sending end of the credit granting application, for example, all the checking rule steps are checked, but the final result is that the execution result is not passed, sending the execution result of the task to the sending end of the credit granting application and informing the client end sending the credit granting application.
In the embodiment of the present invention, regarding the data structures of the global time wheel and the local time wheel, taking Redis to store time wheel data as an example, current pointers and task lists of the time wheel are stored in Redis, and a specific Redis may store a task List using a List data structure, where key names of the task List are spliced by time slice markers tickId and round numbers round, and a corresponding time slice marker tickId and round numbers round may be determined according to a time wheel parameter of a next task to be executed, and a task is taken out from the task List according to the key name, where complexity of the retrieval time at this time is O (1). When accessing the task through the key name, the Hash data structure is used for storing, and fields such as the execution time and the execution times of the next task to be executed are contained in the Hash data structure and are used for executing the next task.
