Description

Technical Field

[0001] The present disclosure relates to the field of distributed and financial technology, and more specifically to a flow limiting method, device, equipment, medium and program product for a flash sale service. Background Art

[0002] The description in this section merely provides background information related to the present disclosure and does not constitute prior art.

[0003] With the popularity of e-commerce, shopping on the Internet platform has become a common phenomenon. Flash sales are a limited-time online shopping activity for the purpose of promotion, allowing multiple people to buy goods online in real time. Bank financial products can also be sold in the form of flash sales. The current flash sales system can provide customers with core flash sales services, which generally include: maintaining flash sales product information before the flash sales, deducting inventory after the flash sales start, and querying the current flash sales inventory. For a flash sales system that only provides core flash sales services, the above three services are encapsulated into three http interfaces, so that different channel platforms can implement flash sales services by calling http interfaces.

[0004] However, the current method of configuring the current limit value in the flash sale system is to configure a fixed current limit value in the server configuration file, and then load the current limit value from the configuration file when the server starts, and write it to the server cache. If the current limit value needs to be modified, the server must be restarted for it to take effect. During the server restart process, the system cannot provide services to the outside world, which increases the difficulty of system emergency response and the time required for system recovery. The flash sale system sets different current limit values ​​for different interfaces to ensure the stability of the system during operation. When the system's performance capacity suddenly increases or reaches the upper limit of the performance capacity, the system's current limit value needs to be modified and reloaded in an emergency. The current emergency process requires manual monitoring of the system's performance capacity, manual modification of the current limit value and restart of the system, which increases the manual steps and operation time of the system emergency response.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present invention and for the convenience of understanding by those skilled in the art.

[0038] An embodiment of the present disclosure provides a flow limiting method for a flash sale service on an application server side.

[0039] Figure 1 The application scenario diagram of the flow limiting method, device, equipment, medium and program product of the flash sale service according to the embodiment of the present disclosure is schematically shown.

[0040] like Figure 1 As shown, the network 104 is used to provide a medium for communication links between the first terminal device 101, the second terminal device 102, the third terminal device 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables.

[0041] The user can use the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as financial service applications, web browser applications, email clients, social platform software, etc.

[0042] The first terminal device 101, the second terminal device 102, and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0043] The server 105 may be a server that provides various services, such as a background management server (only as an example) that provides support for information browsed by the user using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process the received data such as user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0044] It should be noted that, in the first aspect, the flow limiting method of the flash sale service provided in the embodiment of the present disclosure can be executed by the server 105, and in the second aspect, the flow limiting method of the flash sale service provided in the embodiment of the present disclosure can be executed by the first terminal device 101, the second terminal device 102 or the third terminal device 103. Accordingly, in the third aspect, the flow limiting device of the flash sale service provided in the embodiment of the present disclosure can be set in the server 105, and in the fourth aspect, the flow limiting device of the flash sale service provided in the embodiment of the present disclosure can be set in the first terminal device 101, the second terminal device 102 or the third terminal device 103. The flow limiting method of the flash sale service provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Accordingly, the flow limiting device of the flash sale service provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105.

[0045] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0046] The following will be based on Figure 1 The scene described by Figure 2~Figure 7 The current limiting method for the flash sale service of the disclosed embodiment is described in detail.

[0047] Figure 2 A flowchart of a method for limiting the flow of a flash sale service on an application server side according to an embodiment of the present disclosure is schematically shown.

[0048] like Figure 2 As shown, the flow limiting method for the flash sale service of this embodiment includes operations S100 to S300.

[0049] In operation S100, a client request is obtained.

[0050] In the embodiments of this article, the obtained customer request comes from the first terminal device 101, the second terminal device 102 or the third terminal device 103 that interacts with the customer, where the access channels include but are not limited to PC, mini-programs, APP and other access channels of various application platforms.

[0051] In operation S200, in response to a client request, a cache current limit value is obtained from a cache area of ​​an application server and a current limit identification process is performed on the client request, wherein the cache current limit value in the cache area is dynamically updated when the flash sale service is running.

[0052] In one embodiment, the application server includes a transaction processing unit and a flow limiting processing unit. The obtained client request first passes through the flow limiting processing unit, and by calculating the tps value (Transaction per Second) of the access request, it is determined whether it exceeds the cache flow limiting value preset in the cache area. If it exceeds, the flow is limited. If it does not exceed the cache flow limiting value, the client request is forwarded to the transaction processing unit for data processing. In a specific embodiment, the number of client requests per second can be directly counted as the tps value of the client access request. In order to obtain a more reference value for the tps value of the client access request, the tps value of the client access request can also be calculated based on the number of client requests per day. For example, when the number of client requests per day is 1 million, 80% of the client requests per day occur within 8 hours of working time. It can be understood that the number of 800,000 client requests occurring within 8 hours of working time every day is the number of valid reference client requests. The tps value of the client access request can be calculated by the number of valid reference client requests. That is, by calculating the number of 800,000 client requests within 8 hours (i.e., 28,800 seconds), the number of client requests per second is calculated. Through calculation, we can get the TPS value of the client access request to be 27.78.

[0053] In operation S300 , in response to the client request after the flow limiting identification process, the client request after the flow limiting identification process is processed.

[0054] In a specific embodiment, the transaction processing unit of the application server performs business processing on the client request after the flow limiting identification process, returns it to the caller, and saves it in the data storage end, where the data storage end is composed of a database and a distributed cache for storing business data. In this embodiment, a monitoring unit can also be set in another server to monitor the operation of the application server and the data storage end and the performance capacity of the server such as the CPU usage rate and memory usage rate. When the performance of a certain module exceeds the threshold, an alarm is sent to the operation and maintenance personnel in real time. When the operation and maintenance personnel receive the alarm event, they can immediately start the emergency plan, modify the parameters on the distributed configuration center end and publish it.

[0055] Figure 3 A first update flow chart of a method for limiting the flow of a flash sale service on an application server side according to an embodiment of the present disclosure is schematically shown.

[0056] like Figure 3 As shown, in this embodiment, due to business needs, it is necessary to increase or decrease the cache flow limit value in the cache area. Therefore, when the flash sale service is running, the cache flow limit value in the cache area is dynamically updated. Specifically in this embodiment, dynamically updating the flow limit value in the cache area includes operations S400 to S500:

[0057] In operation S400, a current limiting value pushed by a distributed configuration center end electrically connected to an application server end is received;

[0058] In operation S500 , the pushed current limit value is reloaded into the cache area.

[0059] In this embodiment, the distributed configuration center is a platform for centralized management of configuration parameters of different environments and clusters. After the parameters are modified and published at the distributed configuration center, they can be pushed to the application server in real time. Upon receiving the parameter changes, the application server reloads the cache current limit value in the cache area, and can implement hot update of the cache current limit value without downtime, without affecting business continuity, avoiding the problem of the system being unable to provide services to the outside world during the server restart process, and also avoiding the problem of increasing the difficulty of system emergency response and the waiting time required for system recovery.

[0060] Figure 4 A second updated flow chart of the current limiting method for a flash sale service on an application server side according to an embodiment of the present disclosure is schematically shown.

[0061] like Figure 4 As shown, in a specific embodiment of this invention, the cache current limiting value includes a plurality of cache interface current limiting values ​​corresponding to different interface dimensions respectively, so dynamically updating the current limiting value in the cache area includes: operation S400A to operation S500A.

[0062] In operation 400A, at least one second current limiting value pushed by the distributed configuration center is obtained, wherein the second current limiting value is a current limiting value changed and adjusted in the distributed configuration center. The number of second current limiting values ​​can be multiple, each second current limiting value has a corresponding interface dimension, and when there are multiple second current limiting values, each second current limiting value is used to reload the cache current limiting value of the same dimension corresponding to itself in the cache area.

[0063] In operation 500A, at least one second current limiting value is reloaded into the cached interface current limiting value corresponding to the same interface dimension as each second current limiting value in the cache area. In a specific embodiment, the cached current limiting value includes the cached interface current limiting value limit(a) corresponding to interface a, the cached interface current limiting value limit(b) corresponding to interface b, and the cached interface current limiting value limit(c) corresponding to interface c, respectively. The current limiting value changed and adjusted in the distributed configuration center end is the current limiting value corresponding to interface c and the current limiting value corresponding to interface b, so the two second current limiting values ​​are reloaded into the cache area, so that the second current limiting value corresponding to interface c is reloaded into the cached interface current limiting value limit(c) corresponding to interface c, and the second current limiting value corresponding to interface b is reloaded into the cached interface current limiting value limit(b) corresponding to interface b.

[0064] In a specific embodiment of the present invention, which will be briefly described as the first embodiment below, the distributed configuration center includes a server, and multiple clients that are respectively connected to the server for a long time, wherein the server is a distributed cluster that centrally stores configuration parameters. In one embodiment, the server provides an API interface (application programming interface), so that the client can access the server through the API interface and perform operations such as adding, modifying, deleting, and querying parameters. In one specific embodiment, the client is set in the built-in environment of the application server, and in another embodiment, the client is set outside the application server. In this embodiment, the server and the client establish a long connection, that is, the client and the server establish a subscription relationship. In this embodiment, multiple clients correspond to multiple application servers one by one, that is, each client subscribes to all parameter values ​​under the environment and cluster corresponding to each application server in the server. When the server pushes a change message to the outside, each client receives the change message and processes it and notifies the application server of the parameter value under the corresponding environment and cluster in the change message, so that the application server updates the cache current limit value in the cache area. In a specific embodiment, receiving the current limit value pushed by the distributed configuration center electrically connected to the application server includes: obtaining the current limit value corresponding to the application server. A first current limiting value is pushed by a first client corresponding to the server, wherein the first client is a client corresponding to the application server, and the first current limiting value is obtained by processing the change information broadcast and pushed by the first client to the server, and the first current limiting value is the current limiting value under the environment and cluster corresponding to the application server in the change information; by setting the server and the client, maintenance personnel only need to modify the corresponding parameters on the server, which can be broadcast to multiple clients, thereby achieving the effect of adjusting multiple application servers at a time with a single modification, avoiding the problem of low adjustment efficiency and poor emergency response capability caused by manual adjustment of each application server.

[0065] In another embodiment of the present invention, the second current limiting value is a current limiting value that is changed and adjusted in the distributed configuration center. Obtaining at least one second current limiting value pushed by the distributed configuration center includes: obtaining at least one second current limiting value pushed by the first client, wherein the second current limiting value is obtained by the first client processing the change information broadcast by the server, and the second current limiting value is the current limiting value corresponding to different interface dimensions in the application server in the change information. In a specific embodiment based on the first embodiment, the cache current limiting value includes a cache interface current limiting value limit(a) corresponding to interface a and a cache interface current limiting value limit(b) corresponding to interface b, respectively. The first client processes the change information broadcast by the server to obtain the second current limiting value corresponding to interface a and the second current limiting value corresponding to interface b. The first client notifies the second current limiting value corresponding to interface a and the second current limiting value corresponding to interface b to the application server, so that the second current limiting value corresponding to interface a is reloaded to the cache interface current limiting value limit(a) corresponding to interface a, and the second current limiting value corresponding to interface b is reloaded to the cache interface current limiting value limit(b) corresponding to interface b.

[0066] Figure 5 The flowchart of operation S200 of the current limiting method for the flash sale service on the application server side according to an embodiment of the present disclosure is schematically shown.

[0067] like Figure 5 As shown, in a specific embodiment of this invention, in response to a client request, obtaining a current limiting value from a cache area of ​​an application server and performing current limiting identification processing on the client request include: operations S210 to S220:

[0068] In operation S210, the client request is standardized.

[0069] In a specific embodiment, Figure 6 The flowchart of operation S210 of the method for limiting the flow of the flash sale service on the application server side according to the embodiment of the present disclosure is schematically shown. Figure 6 As shown, operation S210 includes: operation S211 to operation S212.

[0070] In operation S211, the interface service information requested by the customer is obtained. For example, the interface service information includes: maintaining flash sale product interface information, flash sale interface information, and querying flash sale inventory interface information.

[0071] In operation S212, the client request is marked with an interface service tag. The client request is marked with an interface service tag. For example, the interface information tag for maintaining the flash sale product, the interface information tag for the flash sale, and the interface information tag for querying the flash sale inventory, etc. By standardizing the data, it is helpful to classify and identify different interfaces of the standardized data in the future.

[0072] In operation S220, the standardized client request is subjected to flow limiting identification processing in the interface dimension.

[0073] In a specific embodiment, Figure 7 The flowchart of operation S220 of the method for limiting the flow of the flash sale service on the application server side according to the embodiment of the present disclosure is schematically shown. Figure 7 As shown, operation S220 includes: operation S221 to operation S223.

[0074] In operation S221, the number of client requests to the first interface service to which the standardized client requests belong within a unit time is counted to obtain the number of first client requests for the first interface service.

[0075] In this embodiment, the number of transactions of the first interface service to which the customer request belongs within a unit time can be obtained. For example, if the customer request is to query the flash sale inventory, the number of customer requests to the first interface service within a unit time can be counted, that is, the number of customer requests to query the flash sale inventory interface within a unit time. In other embodiments, the first interface service to which the customer request belongs can also be for maintaining flash sale products, etc.

[0076] In operation S222, according to the cache interface current limiting value of the first interface dimension corresponding to the first interface service in the cache area, the maximum number of transactions processed per unit time of the first interface service is preset as the fourth current limiting value of the first interface service.

[0077] In this embodiment, for example, according to the cache interface current limit value of the query flash sale inventory interface service in the cache area, the maximum number of transactions processed per unit time of the query flash sale inventory interface service can be preset as the current limit threshold of the query flash sale inventory interface service. Among them, the first interface service is the interface service tag corresponding to the customer request after standardization processing; the first interface dimension is the interface dimension corresponding to the first interface service.

[0078] In operation S223, if the number of first client requests is greater than the corresponding fourth flow limiting value, data flow limiting is performed.

[0079] In this embodiment, taking the customer request for maintaining the flash sale product interface as an example, if the number of customer requests for maintaining the flash sale product interface is greater than the preset flow limiting threshold for maintaining the flash sale product interface, data flow limiting is performed. Data flow limiting includes: obtaining the acquisition time of the customer request for maintaining the flash sale product interface; sorting the customer request for maintaining the flash sale product interface and the multiple customer requests that have been counted according to the acquisition time. If the number of customer requests for maintaining the flash sale product interface does not exceed the preset flow limiting threshold for maintaining the flash sale product interface, data processing is performed directly.

[0080] By classifying customer requests according to the interface dimension, we can avoid resource competition among different interfaces. Moreover, since the current limiting values ​​of different interfaces do not affect each other, we can avoid the problem of resource waste caused by different popularity of different interfaces and achieve the technical effect of rational resource utilization.

[0081] Figure 8 The following schematically shows a flow chart of a method for obtaining a cache current limit value for a flash sale service on an application server according to an embodiment of the present disclosure.

[0082] like Figure 8 As shown, in a specific embodiment of this invention, when the flash sale service is started, the method for obtaining the cache current limit value of the cache area includes: operation S600 to operation S700.

[0083] In operation S600, the application server side obtains a third current limiting value through the distributed configuration center side, wherein the third current limiting value is a current limiting value under the environment and cluster corresponding to the application server side in the distributed configuration center side; specifically in the present embodiment, the client side corresponding to the application server side can access the server side through the API interface and query the current limiting value under the environment and cluster corresponding to the application server side in the server side. In a specific embodiment, the current limiting value under the environment and cluster corresponding to the application server side in the server side may also include multiple current limiting values ​​corresponding to different interface dimensions.

[0084] In operation S700, the third current limiting value is written into the cache area of ​​the application server. In a specific embodiment, multiple current limiting values ​​of different interface dimensions corresponding to the application server in the server are written into the cache area to enable the current limiting mechanism, so that the application server can obtain the cached current limiting value in the cache area at any time during the operation of the flash sale service.
