As shown in fig. 1a, the technical solution provided by the embodiment of the present invention includes:
s110: when the application component receives the parameter access request, the corresponding parameter access program package is determined.
In the embodiment of the invention, the parameter access request can be an access request of a banking business parameter, wherein the parameter can be the banking business parameter, the banking business parameter is used for improving the performance of a banking business system, business operation is facilitated, some abstract business data are designed to be stored in the system, all subsystems are used for unified calling and management to control normal operation of business, and the change of the business parameter data can influence the correct processing of the business operation and the safe operation of the system. Such as pricing parameters, product parameters, interest rates, rate parameters, etc.
In the embodiment of the invention, the application component can be a certain functional component in a banking system, and the banking system can contain application components for deposit, withdrawal and the like. When a user needs to know certain parameters through the banking system, the corresponding application component can be triggered. When the user triggers the application component, the application component receives the parameter access request and determines the corresponding parameter access program package. The parameter access program package and the service access program package are respectively independent. The parameter access program package is used for accessing the distributed parameter database, and the service access program package is used for accessing the service database. The distributed parameter data can store various banking parameters, and the service database can store service related data.
In this embodiment, optionally, before determining the corresponding parameter access package when the application component receives the parameter access request, the method may further include: and determining that the parameter access program package of the application component and the distributed parameter database are statically configured.
In the embodiment of the invention, in the development process of the banking system, program codes for accessing different data sources (different databases can be used) can be put into different program packages by planning the program codes, and the corresponding relation between the program packages and the data sources is specified in the configuration to complete the static configuration.
In the embodiment of the invention, the identifiers of all parameters can be stored in the parameter table, the parameter table can be stored in the public product parameter package, the parameter identifiers in the parameter table in the public product parameter package are all configured correspondingly with the parameter access program package, all parameter reading can be realized, the distributed parameter database can be accessed through the parameter access program package, read-only access to the read-only parameters can be realized, cross-library transactions do not exist, and the safety is higher.
S120: and accessing the distributed parameter database which is correspondingly configured through the parameter access program package, and reading the parameter data which corresponds to the parameter access request in the distributed parameter database.
In the embodiment of the present invention, different program packages may correspond to different data sources, that is, different program packages may correspond to different databases, where a parameter access program package is configured corresponding to a distributed parameter database, and parameters are stored in the distributed parameter database, and the distributed parameter database configured correspondingly may be accessed by running the parameter access program package, and parameter data corresponding to the parameter access request is read from the distributed parameter database.
In the embodiment of the present invention, as shown in fig. 1b, the distributed cluster may be located in two rooms, where 4 machines including Pak1-Pak4 exist in each room. The physical unit in which the application component is located can access the distributed parameter database by way of a static data source. Namely, the distributed cluster can be accessed through the parameter access program packet corresponding to the parameter, and the distributed parameter database can be accessed through the distributed cluster. The distributed cluster may be a distributed parameter cluster, a distributed batch processing cluster, or the like. A distributed cluster may be referred to as a distributed application processing cluster, which refers to a cluster used for application processing in a distributed system. The distributed parameter database can be transversely expanded, and the concurrent data access requirements can be met.
S130: when the application component receives a maintenance request of a target parameter, the target parameter is maintained in a distributed parameter database based on the maintenance request.
In an embodiment of the present invention, the maintenance request may refer to a synchronization request. When the target parameters need to be synchronized, a user can trigger corresponding operation through the application component, so that the application component receives a maintenance request of the target parameters, the target parameters are sent to the distributed cluster based on the maintenance request, and the distributed cluster maintains the target parameters in the distributed parameter database. The distributed cluster may include a distributed parameter cluster, a distributed batch processing cluster, and the like.
On the basis of the foregoing embodiment, the method provided in the embodiment of the present invention may further include: when the application component receives a service access request, determining a corresponding service access program package; accessing a correspondingly configured service database through the service access program package, and reading service data corresponding to the service access request in the service database; the parameter access program package and the service access program package for accessing the service database are independent respectively. Specifically, if the user needs to query the service data, the service access operation may be triggered at the relevant application component, so that the service component receives the service access request and accesses the service database configured correspondingly through the service access package.
In this embodiment of the present invention, optionally, when the application component receives a service access request, before determining a corresponding service access package, the method may further include: and performing static configuration on the service access program package and the service database. The service access program package and the service database are configured correspondingly, when service access is needed, the service database is accessed through the corresponding service access program package, switching of data sources can be avoided, and safety is high. In the embodiment of the invention, the parameter access program package and the service access program package are independent respectively, different data sources (databases) are accessed through different program packages, the switching of the data sources can be avoided, the safety is higher, the static configuration is carried out through the parameter access program package and the distributed parameter database, and the static configuration is carried out through the service access program package and the service database, so that the distributed parameter database and the service database can be accessed, the application components do not need to be modified, the application components are not intrusive, and the development cost is reduced.
The distributed parameter database is separated from the service database, when one database fails, the distributed parameter database does not affect each other, and when one parameter copy database in the distributed parameter database fails, the use of the application component is not affected.
In the related art, in the banking system, some parameters are usually added and maintained by accessing data from the outside or in a parameter maintenance interface through a service, and the parameters are validated into a parameter database in an online transaction manner. Each application component is then read through the component.
In a banking system, banking parameters such as interest rate parameters, exchange rate parameters, product parameters, etc. are typically added and maintained by accessing data from the outside or at a parameter maintenance interface by the service, and the parameters are validated into a parameter library through an online transaction. Each application component is then accessed by reading the components provided by the parameter component.
In the old system, various parameters are subjected to parameter maintenance transaction, service parameters are maintained in a unique parameter database, the addition, deletion and modification of the database can be realized through atomic transaction, and an application component can directly call a component to access the parameter database, so that the parameters can be read, and therefore, complete service logic is realized.
In a distributed system, since each physical unit is autonomous, in order to implement local access to the reading by means of a component, corresponding component and parameter library databases need to be deployed in all the physical units. Under the condition that a large number of physical units exist, a large number of parameter databases exist, and how to ensure that all of the parameter databases are valid correctly and ensure the global consistency, real-time performance and atomicity of parameter maintenance becomes a difficult problem to be solved urgently.
The real-time property of the parameter maintenance may mean that the parameter needs to take effect in the parameter data of the distributed system within a short time interval after the parameter is maintained (may be updated) in other databases corresponding to the common service unit; the common service unit may be a cluster dedicated to common services in a distributed system, and the common service unit may include a host system. Global consistency can mean that parameters are required to be consistent among all physical units when the parameters take effect, and some physical units cannot use old parameters; atomicity/isolation may refer to the situation that parameter maintenance may need to be completed by maintaining multiple tables, where there is an association between tables, and thus, the parameter maintenance operation must ensure atomicity and there cannot be partial maintenance. Data in the maintenance process should not be read by the application service.
In the old system, since only one parameter database is provided, the maintenance of the parameter database such as addition, modification, deletion and the like and the reading of the parameters are all completed through atomic transactions. In the existing distributed system, there are several schemes as follows:
(1) online synchronous replication: the online transaction on all the physical units is synchronously called to realize the online transaction by a combined transaction mode, the successful transaction of all the physical units is regarded as the successful maintenance (which can be referred to as synchronization) of the parameter database, and the successful transaction of the physical machine in the preamble is corrected if the online transaction on any one physical machine on the execution chain fails. The method can respond to the user only when all the parameter databases are maintained successfully, and all the parameter databases need to be rolled back as long as one physical unit fails, so that the user experience is influenced; the situation that the maintenance is not successful for a long time may exist by using the scheme, so that the parameters cannot be timely validated and the production problem is caused.
(2) And a database replication technology: through the bottom layer technology of the database, for the maintenance request, the main database of the parameter cluster can execute maintenance (write-in) operation, and can respond to the user after synchronizing the data to all the parameter databases; the method needs the same database product to be used by a main database and a parameter database, depends on a specific database, causes limitation on the type selection of the database, and is difficult to ensure the association among a plurality of data tables for a scene of synchronizing the plurality of data tables at one time, so that the atomicity/isolation of the parameters cannot be ensured by the scheme for the scene of using the banking parameters in the distributed system of the scheme.
(3) Asynchronous replication technology: that is, after the master database is maintained, the message is pushed to the parameter databases in all the physical units through a message mechanism, such as Redis, EDA, MQ, etc., and after the message is pushed, it is not guaranteed that all the physical units are maintained correctly. In the method, the parameter database can asynchronously synchronize data, the method ensures the usability of the system, but sacrifices the consistency of the data, for the banking parameters, the parameters on different physical units at the same time are inconsistent, financial risks can be caused, and as for the same time, the interest rates of different branches are inconsistent, the supervision problem can be caused, and the scheme can not ensure the consistency of the parameters.
According to the technical scheme provided by the embodiment of the invention, the parameters are stored in the distributed parameter database, so that the parameter database is prevented from being deployed on each physical machine, the application component on each physical machine receives the parameter request of the target parameter, the target parameter can be maintained in the distributed parameter database, the condition of maintaining the parameter database on each physical machine is avoided, and the consistency, the real-time property and the atomicity or the isolation of the parameters of each physical unit are ensured, wherein the distributed parameter database does not relate to multiple maintenance (synchronization), the real-time property is high, the distributed parameter database is accessed through one access point (distributed cluster), the difference of different nodes is avoided, the consistency is ensured, and the risk of inconsistent parameter maintenance is reduced; according to the embodiment of the invention, the distributed parameter database which is correspondingly configured is accessed through the corresponding parameter access program packet, so that data source switching does not exist in the parameter reading process, and the safety is higher.
According to the technical scheme provided by the embodiment of the invention, when the application component receives the parameter access request, the distributed parameter database which is correspondingly configured is accessed through the parameter access program package, and the parameter data which is fed back by the distributed parameter database and corresponds to the parameter access request is received, namely, the parameters are stored in the distributed parameter database, the consistency of the parameters and the like can be ensured by accessing the distributed parameter database and maintaining the parameters in the distributed parameter database.

In an implementation manner of the embodiment of the present invention, optionally, maintaining the target parameter to another database based on the maintenance request includes: adding the target parameter to other databases based on an addition request of the target parameter; correspondingly, under the condition that the target parameter is successfully maintained in the other databases and the target parameter is unsuccessfully maintained in the distributed parameter database, if the application component receives the maintenance request of the target parameter again, the generation of error information is refused, and the target parameter is maintained in the other databases and the distributed parameter database again, the method includes: and under the condition that the target parameters are successfully added to the other databases and the target parameters are unsuccessfully added to the distributed parameter database, if the application component receives the addition request of the target parameters again, the addition request is sent to the host system to maintain the target parameters to the other databases again, the generation of error information is refused, and the addition request is sent to the distributed cluster to maintain the target parameters to the distributed parameter database again. Under the condition that the target parameters are successfully added to other databases and the target parameters are unsuccessfully added to the distributed parameter database, the original maintenance transaction (synchronous transaction) of the target parameters is modified by the application component, and the target parameters are added, so that the transaction is completed by modifying under the condition that the target parameters exist.
In an implementation manner of the embodiment of the present invention, optionally, maintaining the target parameter to another database based on the maintenance request includes: modifying the target parameters to other databases based on the modification request of the target parameters; correspondingly, under the condition that the target parameter is successfully maintained in the other databases and the target parameter is unsuccessfully maintained in the distributed parameter database, if the application component receives the maintenance request of the target parameter again, the generation of error information is refused, and the target parameter is maintained in the other databases and the distributed parameter database again, the method includes: under the condition that the target parameter is successfully modified to the other databases and the target parameter is unsuccessfully modified to the distributed parameter database, if the application component receives the modification request of the target parameter again, the modification request is sent to the host system to re-modify the target parameter to the other databases, the generation of error information is refused, and the modification request is sent to the distributed cluster to re-modify the target parameter to the distributed parameter database. For the modification of the target parameter, the application component supports the addition (which can be called addition) process under the condition that the target parameter does not exist.
In an implementation manner of the embodiment of the present invention, maintaining the target parameter to another database based on the maintenance request includes: deleting the target parameter in other databases based on the deletion request of the target parameter; correspondingly, under the condition that the target parameter is successfully maintained in the other databases and the target parameter is unsuccessfully maintained in the distributed parameter database, if the application component receives the maintenance request of the target parameter again, the generation of error information is refused, and the target parameter is maintained in the other databases and the distributed parameter database again, the method includes: and under the condition that the target parameter is successfully deleted in the other databases and the target parameter is unsuccessfully deleted in the distributed parameter database, if the application component receives the deletion request of the target parameter again, sending the deletion request to a host system, refusing to generate error information, and sending the deletion request to a distributed cluster so as to delete the target parameter in the distributed parameter database again. When the target parameter is successfully deleted in the other databases and the target parameter is unsuccessfully deleted in the distributed parameter database, the application component supports that the error information is rejected (that is, no error information is generated) when the target parameter does not exist in the distributed parameter database, so that the deletion request can be retransmitted to delete the target parameter again.
In the embodiment of the present invention, when the second parameter is maintained in a real-time batch manner (for example, the second parameter may be deleted), a plurality of data files may be configured by an application component (a product development component, or the like), and a real-time maintenance request for the second parameter is sent to the host system and the distributed cluster, respectively, so as to generate two real-time batch tasks. When the host system maintains the distributed parameter databases to be inconsistent with other databases and the distributed cluster, the application component does not generate error information and supports the retransmission processing of the failed tasks. Wherein, the application component can support single point of failure task retransmission. For example, in the case that the maintenance of the third parameter to the distributed parameter cluster fails and the maintenance to the other database succeeds, the application component may send a maintenance request of the third parameter to the distributed cluster, so as to maintain the third parameter again in the distributed parameter database through the distributed cluster.
In the embodiment of the present invention, when the third parameter is maintained in a batch-by-day manner, the application component may be configured with a plurality of data files, and a daily-by-day maintenance request for the third parameter is sent to the host system and the distributed cluster, respectively, so as to maintain the third parameter in other databases and the distributed parameter database. When a fault occurs in the maintenance process, fault information can be displayed so as to manually process the abnormity. For example, when the third parameter is inconsistent with the maintenance of other databases and the distributed databases, manual processing may be performed, and the manner of manual processing may refer to the manner in the related art.
In the embodiment of the present invention, when the first parameter is maintained in an online transaction manner, if the first parameter maintains the other databases and the distributed parameter database partially successfully and partially fails, failure information (information that the combined transaction fails may be returned), and a user is required to initiate a maintenance request of the first parameter again (the bottom-of-pocket mechanism of the application component ensures that the second retransmission is successful). If the first parameter is the accessed quoted price data, an early warning mechanism can be kept, and when a fault occurs in the maintenance process, fault information can be displayed so as to manually process the abnormity, wherein the fault information can comprise a fault point, a fault reason and the like.
Therefore, under the condition that the target parameters are successfully maintained in the other databases and the target parameters are unsuccessfully maintained in the distributed parameter database, if the application component receives the maintenance request of the target parameters again, the generation of error information is refused, and the target parameters are maintained in the other databases and the distributed parameter database again, so that the condition that the parameters of the two databases are not maintained consistently can be avoided, and the consistency of the two databases can be maintained.
