Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Before discussing the exemplary embodiments in greater detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts various operations (or steps) as a sequential process, many of the operations may be performed in parallel, concurrently, or concurrently. Additionally, the order of operations can be rearranged. The process may be terminated when its operation is complete, but may also have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

Example 1

1 is a flowchart of a method for using parameters provided in Embodiment 1 of the present invention, which is applicable to the case of performing multi-level caching of parameters. For implementation, the apparatus can be implemented in software and/or hardware, and can generally be integrated in computer equipment.

A parameter, also called a parameter variable, is a variable. For a given application, it can be an assigned constant value; in general, it can be a variable that controls other quantities (or events) that change with it.

The parameter user refers to the party that uses the parameter, and the parameter provider refers to the party that provides the parameter. Both are application layer concepts.

As shown in FIG. 1 , the parameter usage method provided in this embodiment is applied to the parameter user, and specifically includes:

S110. In the process of executing the target operation, send a parameter loading request to the parameter cache server.

The target operation refers to any kind of operation, which can be any kind of program. Taking financial business as an example, the target operation can be transfer operation, withdrawal operation, etc.

The parameter cache server refers to a server for caching parameters, for example, a Redis-based parameter cache server or a cache-based parameter cache server.

In the process of the parameter user performing the target operation, if the target parameter (any parameter involved in the target operation process) needs to be read, a parameter loading request can be sent to the parameter cache server to obtain the parameter cache server. target parameter. The parameter loading request carries the unique identification information of the target parameter that needs to be read. Optionally, the target parameter may be a parameter that is frequently used.

Optionally, before sending the parameter loading request to the parameter cache server, it further includes: reading the parameter cache configuration information in the configuration center; correspondingly, sending the parameter loading request to the parameter cache server, which may be specifically: according to the parameter cache configuration The information sends a parameter loading request to the parameter cache server.

The configuration center is used to store the configuration information related to the parameter usage method, such as the IP address information of the server, the port information, the url of the related service, and so on. Optionally, the configuration information stored in the configuration center may include parameter cache configuration information, parameter storage configuration information, and the like. The parameter cache configuration information can be used to access the data cache server to obtain relevant parameter values in the parameter cache server; the parameter storage configuration information can be used to access the database server of the parameter provider to cache the corresponding parameters. The configuration information of the configuration center can be added and/or modified through the operation interface of the configuration center.

After the configuration center is started, the parameter user reads the parameter cache configuration information in the configuration center. When the parameter cache server needs to be accessed to obtain the target parameters, the parameter cache server is accessed according to the read parameter cache configuration information, and a parameter loading request is sent to the parameter cache server.

S120: Acquire the target parameters fed back by the parameter cache server according to the parameter loading request, and continue to perform the target operation according to the target parameters; wherein, the target parameters in the parameter cache server are loaded in the database server of the parameter provider.

The parameter cache server pre-loads the target parameters in the database server of the parameter provider. When receiving the parameter loading request sent by the parameter user, it parses the parameter loading request to determine the target parameters to be fed back, and feeds back the locally cached target parameters to the parameters. user. Furthermore, after the parameter user obtains the target parameter fed back by the parameter cache server, the target operation can be continued according to the target parameter.

In this process, there is no information exchange between the parameter consumer and the parameter provider, but information exchange with the parameter cache server, thereby reducing the access pressure to the parameter provider's application server and database server. Especially when a large number of parameter consumers correspond to the same parameter provider, setting the parameter cache server to provide parameters for the parameter consumers can greatly reduce the access pressure to the application server and database server of the parameter provider.

Optionally, the parameter cache server is a distributed cache server, which supports elastic expansion, and can then dynamically increase or decrease the number of nodes to cope with the changing data access load. By using the principle of parameter proximity access, the overall throughput of the system can also be indirectly improved. , which can meet the requirements of high concurrency, high expansion, and high availability.

Optionally, before providing the parameter user with the target parameters loaded in the database server of the parameter provider, the parameter cache server reads the parameter storage configuration information in the configuration center, and accesses the parameter provider according to the parameter storage configuration information. The party's database server loads the target parameters.

After the configuration center is started, the parameter cache server reads the parameter storage configuration information in the configuration center. When the database server that needs to access the parameter provider loads the target parameters, the database server of the parameter provider is accessed according to the read parameter storage configuration information, and the target parameters are loaded in the database server.

As an optional implementation manner, after acquiring the target parameter fed back by the parameter cache server according to the parameter loading request, the method further includes: if the target parameter satisfies a preset condition, storing the target parameter in a local cache.

After acquiring the target parameter, the parameter user determines whether the target parameter satisfies the preset condition, and if so, caches the target parameter locally, and if not, does not process the target parameter. The preset condition refers to a condition suitable for local caching, for example, the parameter value may be a constant value and the parameter usage frequency is greater than the preset threshold value.

As an optional implementation manner, sending a parameter loading request to a parameter caching server may specifically include: sending a parameter loading request to a parameter access interface of the parameter caching server; correspondingly, acquiring the target parameters fed back by the parameter caching server can be specifically as follows: if the parameter loading response fed back by the parameter access interface according to the parameter loading request indicates that the parameter cache server does not store the target parameter, wait for the parameter cache server After the target parameter is loaded in the database server, the parameter loading response is fed back again through the parameter access interface; the target parameter carried in the parameter loading response fed back again through the parameter access interface is acquired.

In this embodiment, the parameter cache server provides a general parameter access interface, which is transparent to all parameter users, and is used to receive a parameter loading request sent by the parameter user, and respond to the parameter loading request.

The parameter uses the parameter access interface of the parameter cache server to send a parameter load request. After the parameter access interface of the parameter cache server receives the parameter load request, it parses the parameter load request, obtains the target parameters that match the parameter load request, and generates parameters that carry the target parameters. The loading response is fed back to the parameter consumer.

After parsing the parameter loading request, if the parameter caching server cannot find a target parameter matching the parameter loading request in the local cache, it may first feed back the parameter used to indicate that the parameter caching server does not store the target parameter to the parameter user Loading response to instruct the parameter user to wait for it to be loaded from the database server of the parameter provider, and at the same time access the database server of the parameter provider to perform the loading operation on the target parameter, and generate a parameter load carrying the target parameter after the loading is completed The response is fed back to the parameter consumer.

After receiving the parameter loading response fed back by the parameter caching server, if the parameter loading response indicates that the parameter caching server does not store the target parameters, the parameter user can wait for the parameter caching server to send the parameter loading response carrying the target parameters again.

Optionally, the parameter access interface supports a key-value pair (Key-Value) operation.

In the parameter loading request, the key value of the parameter to be loaded can be carried. The parameter cache server parses the received parameter loading request through the parameter access interface, obtains the key value carrying the parameter to be loaded, and then according to the key value locally The corresponding Value value is queried in the cache, or the corresponding Value value is queried in the database server of the parameter provider according to the Key value and loaded into the local cache, and then the parameter loading response can be generated according to the Value value and fed back to the parameter user.

The cache records in the parameter cache server can be processed correspondingly through the parameter access interface. Optionally, in response to a cache record processing request, the parameter cache server performs an operation matching the cache record processing request through a parameter access interface; the cache record processing request includes at least: a cache record addition request, a cache record deletion request, Cache record update request, cache record query request.

When the parameter cache server responds to a request for adding a cache record, it can add one cache record at a time, or it can add multiple cache records in batches, and count the number of new cache records. Specifically, the cache record addition process may be performed according to the Key value and the Value value of the target parameter. Optionally, when adding a cache record, the expiration time of the newly added parameter may also be carried (the unit may be milliseconds). If a cache record matching the request for adding a cache record already exists in the parameter cache server, the existing cache record can be overwritten.

When the parameter cache server responds to a cache record deletion request, it can delete one cache record at a time, or delete multiple cache records in batches, and count the number of cache records deleted. Specifically, the cache record deletion process may be performed according to the Key value of the target parameter.

When the parameter cache server responds to the cache record update request, it may add a Value value or replace the Value source value with the Value update value when the parameter Key value is the same. In the case of adding a Value value while the parameter Key value is the same, if a cache record matching the Key value and the new Value value in the cache record update request already exists in the parameter cache server, the cache record update request can be ignored. In the case where the value of the parameter key is the same as the value of the value source, if there is no cache record matching the key value in the cache record update request in the parameter cache server, the cache record update request can be ignored. In the case of replacing the Value source value with the Value update value when the parameter Key value is the same, the cache record update request can also carry the Value source value, only if there is a cache record matching the Key value and the Value source value in the parameter cache server When the corresponding Value update value is used to replace the Value source value.

When the parameter cache server responds to a cache record query request, it can query one cache record at a time, or query multiple cache records in batches. Specifically, the cache record query processing can be performed according to the key value of the target parameter. The cache record query request may be generated according to the parameter loading request received by the parameter cache server.

In addition, the parameter cache server can also realize the clearing process of all cache records through the parameter access interface, and submit the cache record processing request waiting in the queue to the data persistence layer.

In an optional implementation manner, the parameter cache server, in response to the parameter update request, eliminates the cached data in the parameter cache server that matches the parameter update request; After being written in the database server of the parameter provider, the update parameter is loaded in the database server of the parameter provider.

When updating parameters, the cache is eliminated first and then the database is written. Wherein, when the parameter cache server receives the parameter update request, it first eliminates the cached data matching the parameters to be updated carried in the parameter update request, and then waits for the database server of the parameter provider to execute the parameter update matching the parameter update request. Operation, when the parameter user loads the parameter in the parameter cache server, the corresponding update parameter in the database server of the parameter provider is loaded into the local cache.

In this embodiment, the method of first eliminating the cache and then writing the database will not cause the problem of inconsistency between the parameter cache server and the database.

In the technical solution provided by the embodiment of the present invention, the parameter cache server loads the target parameters in the database server of the parameter provider, and when the parameter user performs the target operation and needs to obtain the target parameters, the parameter cache server loads the target parameters to execute the target parameters. operation, thereby reducing the access pressure of the parameter user to the application server and database server of the parameter provider, and improving the overall availability and reliability of the system.

Embodiment 3

FIG. 3 is a schematic flowchart of a multi-level cache mechanism to start loading to which a method for using parameters according to Embodiment 3 of the present invention is applied. This embodiment provides a specific implementation manner on the basis of the foregoing embodiment.

Referring to FIG. 3 , the parameter multi-level caching mechanism provided by this embodiment is jointly implemented by the parameter user and the parameter provider, and the caching involves multiple levels such as the parameter user’s local cache, distributed cache, parameter provider’s local cache, and parameter provider’s database. cache. Among them, the distributed cache provides a general processing mode and parameter access interface, so that the parameter user does not need to care about the specific implementation logic. While reducing the application complexity, it also relieves the parameter user from the parameter provider application server and database server. access pressure, thereby improving the overall availability and reliability of the system.

As shown in FIG. 3 , the process of starting the loading of the multi-level cache mechanism to which the parameter usage method provided in this embodiment is applicable includes:

S310, the parameter provider database server is started.

S320, the configuration center is started.

S330, the distributed cache server is started, and the configuration center is read.

S340. The distributed cache server loads the parameters in the parameter provider database server.

S350, the parameter provider application server starts, and reads the configuration center.

S360. The parameter provider application server loads the parameters in the parameter provider database server.

Among them, for the parameter provider, loading commonly used parameters into the local cache can also reduce the access pressure on the database server of the parameter provider.

S370, the parameter user application server is started, and the configuration center is read.

S380. The parameter user application server loads the parameter on the distributed cache server.

Among them, the parameter loading source of the parameter user application server is the distributed cache server, the parameter loading source of the distributed cache server is the parameter provider database server, and the parameter loading source of the parameter provider database server is other modules, such as the batch of web management Import or single maintenance. The parameter cache configuration information is stored in the configuration center, which may include parameter cache configuration information, parameter storage configuration information, etc., and does not store any parameter values.

For details that are not explained in this embodiment, please refer to the foregoing embodiments, which will not be repeated here.

In the technical solution provided by this embodiment, a distributed core parameter multi-level caching mechanism is designed to provide a unified cache access interface and communication protocol for the application layer (parameter user and parameter provider), so that the application layer does not need to care about the specific implementation Logic not only reduces the application complexity, but also reduces the access pressure of parameter users to the application server and database server of the parameter provider, improves the overall availability and reliability of the system, and lays the foundation for the implementation of the distributed core in the financial industry. With a solid foundation, it no longer needs to rely on third-party products, and is completely independent and controllable.

The following descriptions are combined with specific application scenarios:

In the scenario of "single account transfers cannot exceed N transactions at the same time", the number of transfers needs to be counted. Counting is a very heavy task for the database, requiring a large number of rows to be queried, and finally the counting conclusion is drawn. When the data changes When it needs to be refreshed again, it will greatly affect the performance. At this point, you can design a counting service to write the counting results to the database and load them into the distributed cache server. When the data changes, call the counting service to increase or decrease the count, and to the database and distributed cache server. The count result is updated. In the process of single-account transfer operation, when it is necessary to obtain the count result of the number of single-account transfers, it is loaded in the distributed cache server, without accessing the database, nor through the database for statistics, which reduces the need for parameter providers. Access pressure on application servers and database servers.

In the "list sorting and paging" scenario, you need to obtain some list data, sort and paginate the data, for example, sort and paginate the most frequently accessed data in real time. In this case, the data structure in the cache is completely different from that in the database. If the database is completely implemented, all rows will be queried according to a certain condition, sorted according to a certain field, and then displayed in pagination. When the amount of data is relatively large or the transaction peak, this method will seriously affect the performance. In the cache, there is no need to have a key value per line. You can use the Redis list method for storage. Of course, the length of the list is limited, and so much data in the database will definitely not fit, but users or customers may only care about For the data on the first few pages, the number of data items is only tens or hundreds, and the maximum is about 1,000. If the service ID is maintained, the list can completely put these data. At this time, the sorted data in the database can be placed in the distributed cache server (Redis), and then when the paging read operation is performed, the data retrieval list can be directly loaded in the distributed cache server, which can greatly improve the The speed of page turning and viewing does not need to access the database, thereby reducing the access pressure on the application server and database server of the parameter provider. At the same time, the background can also initialize and refresh the cache asynchronously through a thread, and save a data timestamp in the distributed cache server. When there is data update, the cache refresh is triggered according to the data timestamp in the distributed cache server through an asynchronous task. operate.
