[0033] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0034] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments provided herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the embodiments provided below are partial embodiments for implementing the present invention, rather than providing all embodiments for implementing the present invention. In the absence of conflict, the technical solutions recorded in the embodiments of the present invention can be implemented in any combination.

[0036] It should be noted that, in the embodiments of the present invention, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a method or apparatus including a series of elements includes not only the elements explicitly recorded, but also includes other elements not explicitly listed, or also includes elements inherent to the implementation of the method or apparatus. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other related elements (such as steps in a method or modules in an apparatus, such as a module that can be a part of a circuit, a part of a processor, a part of a program or software, etc.) in the method or apparatus including the element.

[0037] For example, the preheating method for an application provided in an embodiment of the present invention includes a series of steps, but the preheating method for an application provided in an embodiment of the present invention is not limited to the steps described in this document. Similarly, the preheating device for an application provided in an embodiment of the present invention includes a series of modules, but the preheating device for an application provided in an embodiment of the present invention is not limited to including the modules explicitly described, and may also include modules that need to be set for obtaining relevant information or performing processing based on information.

[0038] Before introducing the applied preheating method, the application background of the present invention is first explained.

[0039] In the development and use of modern mobile applications, user experience (UX) is a crucial factor. Users expect applications to respond quickly to their operations and provide a smooth interactive experience.

[0040] However, in actual applications, especially after the cold start of the application system, after the user interface (UI) is loaded, there may still be untimely responses. This phenomenon not only affects the user experience, but may also cause users to lose satisfaction with the application and even give up using the application.

[0041] Based on the above technical problems, the technical concept of the present invention is as follows: if the process of preparation operation, verification operation, pre-calculation operation, or / and initialization operation of the application can be implemented in advance during the cold start phase of the application, then the problem of slow business response speed caused by the above process can be avoided in the subsequent operation phase. That is, the application can be preheated in advance. In the implementation of the preheating operation, different types of preheating elements are obtained. If the relevant elements of functions or scenarios that are frequently used by the application during operation can be preferentially selected as preheating elements, then when the application is cold started, the implementation of the preheating operation occupies less operating resources and ensures the purpose of rapid response of subsequent business.

[0042] The technical solution of the present invention is described in detail below through specific embodiments. The execution subject of the present invention is an electronic device, which can be a terminal device or a service device.

[0043] Optionally, the terminal device is a device with an application installed, such as a mobile phone, a computer, a tablet, some servers, etc.; the service device is a device that provides services for the application in a distributed system, such as a control server, etc.

[0044] Accordingly, Figure 1 The schematic diagram of the architecture of the preheating method for the application provided by the present invention is shown as follows: Figure 1 As shown, the architecture includes: a preheating component (English: Warmuper) and a startup component (English: Bootstrap).

[0045] In the first part, the Warmuper component abstracts the warmup() interface of the warmup logic. This component can implement the specific warmup logic by inheritance, namely, the following components: the interface warmup component (English: ApiWarmuper), the database warmup component (English: SqlWarmuper), the Shardingsphere warmup component of Structured Query Language (SQL) (English: ShardingsphereWarmuper), and the Java virtual machine (English abbreviation: JVM) warmup component (English: JVMWarmuper);

[0046] Exemplarily, the ApiWarmuper component is used to perform related operations of the preheating element of the interface verification type, that is, to simulate actual user requests and perform basic processing on the response of each interface, such as checking the response status code to ensure that the interface can correctly return the expected result; the SqlWarmuper component is used to perform related operations of the preheating element of the database query type, that is, to execute SQL queries and return the query results to the database; the Shardingsphere preheating component is used to perform related operations of the preheating element of the database script type, that is, to perform syntax analysis of each SQL and cache the analysis results; the JVM preheating component is used to perform related operations of the preheating element of the function call type, that is, through performance analysis (English: profiling), frequently called functions or hot code in the application are identified, and the JVM's JIT (Just-in-time compiler) is triggered to compile the code path of the commonly used code into local machine code.

[0047] The second part is the Bootstrap component abstraction Bootstrap() interface. This component abstraction is used to integrate various systems so that the warm-up operation can be performed within the initialization life cycle before each system is started, that is, the health check type component (English: HealthIndicator) of the boot class or mechanism and the service interaction type component are obtained;

[0048] Exemplarily, the health check type component of the bootstrap class or mechanism is used to perform related operations of the preheating element of the health check type. The health check operation is automatically performed when the application starts to check whether the database connection, cache system or other dependent services are normal; the service interaction type component is used to perform related operations of the preheating element of the service interaction type. The readinessProbe is configured in the Kubernetes configuration file to check whether the application has completed preheating and is ready to receive traffic, ensuring that the application is ready to process requests before officially receiving traffic.

[0049] Above Figure 1 The embodiment shown is a structure of a component to be implemented. In practical applications, the configuration thereof can be changed, expanded, or reduced based on user needs or other factors. The technical solution of the present invention is described in detail below through specific embodiments.

[0050] Figure 2 FIG. 1 is a flow chart showing a first embodiment of a preheating method applied by the present invention, the method being executed by a terminal device. Figure 2 As shown, the method comprises the following steps:

[0051] S21. When detecting that an application is started in the terminal device, obtaining at least one type of preheating item;

[0052] Among them, each type of preheating item includes: a preset number of preheating elements with a usage frequency from high to low under the type, and the preheating elements are elements that require preparation operations, verification operations, pre-calculation operations, or / and initialization operations before the application is run.

[0053] In this step, when the startup of an application in the terminal device is detected, that is, before the application provides the user with an interactive interface for operation, after the user clicks the icon of the application, or during the loading process of the application, at least one type of preheating item is obtained, and each type of preheating item includes: a preset number of preheating elements with a usage frequency from high to low.

[0054] Optionally, the value of the preset number can be based on experience and can be determined by taking into account the loading performance of the application, the system resources of the terminal device, and other conditions.

[0055] For example, 10, 20, etc., the preset number corresponding to each type of preheating item may be different and is not limited here.

[0056] Optionally, the type of the warm-up item includes at least one of the following: interface verification type, database query type, database script type, function call type, health check type, and service interaction type.

[0057] In a possible implementation, the types of the above preheating items are illustrated as follows:

[0058] 1. Preheating elements of interface verification type: various business-related API interfaces;

[0059] 2. Warm-up elements of database query type: various SQL query interfaces;

[0060] 3. Warm-up elements of database script type: various SQL;

[0061] 4. Preheating elements of function call type: functions or hot code called in the application;

[0062] 5. Health check type warm-up elements: various health check probe types, such as checking database connections, cache systems, and other dependent services;

[0063] 6. Warm-up elements of service interaction type: service class, such as loading cache, establishing database connection, etc., to implement elements that are ready to process requests before officially receiving traffic.

[0064] Optionally, at least one type of preheating item may be pre-cached in the terminal device, or may be obtained from the service device in real time.

[0065] S22: Perform a preheating operation on the application program according to at least one type of preheating item.

[0066] In this step, each preheating element in the at least one type of preheating item obtained above is used to preheat the application.

[0067] Optionally, for each type of preheating item, the execution order of the preheating operation may be to start with the most frequently used preheating element; different types of preheating items may be executed one by one in sequence; or the preheating operation may be executed using each preheating element at the same time.

[0068] In a possible implementation, the types of the above preheating items are exemplified:

[0069] 1. Preheating elements of interface verification type, such as calling the API interface of the product list, can simulate user requests, then access the API interface, cache the response results of the API interface, and complete the preheating operation corresponding to the API interface; one implementation is the interface preheating component ApiWarmuper, which is used to perform application initialization operations and cache preheating operations through the interface;

[0070] 2. Warm-up element of database query type: For example, for the SQL query interface of A, execute the SQL query of A and cache the query result to complete the warm-up operation corresponding to the SQL query interface of A; one implementation is the database warm-up component SqlWarmuper, which is used to trigger the database cache or even the data warm-up in the database when the application starts;

[0071] 3. Warm-up elements of database script type: For example, for SQL of B, execute syntax analysis of SQL of B, change the analysis result into cache, and complete the warm-up operation corresponding to SQL of B; one implementation is Shardingsphere warm-up component ShardingsphereWarmuper, which is used to warm-up SQL syntax analyzer, perform syntax analysis on important SQL in advance and write into cache, so as to reduce the cost of later SQL syntax analysis.

[0072] 4. Preheating elements of function call type: For example, the hotspot code C called in the application triggers the JVM's JIT to compile the code path of the frequently used hotspot code C into local machine code. One implementation is the JVM preheating component JVMWarmuper, which is used to preheat the JVM when the JVM starts. For example, it starts preheating for functions that are frequently called after profiling to trigger local machine code conversion. It can even reduce the JIT preheating time by importing the JVM information in the pre-release environment into the production environment.

[0073] 5. Preheating elements of health check type: for example, checking the health check probe class of database connection, executing the health check operation of checking the database connection, exchanging the execution result into cache, and completing the preheating operation corresponding to the health check probe class of checking the database connection; one implementation is that SpringCloudWebBootstrap is used to integrate SpringCloud's network (English: Web) application, and through the HealthIndicator (health check probe) mechanism, preheating operation is performed before the life cycle of the Web application providing external services;

[0074] 6. Preheating elements of service interaction type: for example, establishing a database connection, executing the database connection establishment operation, caching the establishment result, and completing the preheating operation corresponding to establishing the database connection. One implementation is that K8sBootstrap is used to integrate Kubernetes and perform preheating operations before the Kubernetes application is available.

[0075] Optionally, S22 may include any of the following implementations:

[0076] First, preheating the application programs one by one according to each of the preheating elements of a preset number in at least one type of preheating items;

[0077] In this implementation, for each of the first preset number of preheating elements in each preheating item, for example, the first three preheating elements, the first preheating element can be used to preheat the application. After completion, the second preheating element can be used to preheat the application, and then the third one can be executed. This process can provide consistency in the data used in the preheating process and facilitate the control of the preheating process.

[0078] Secondly, the application is preheated at the same time according to each preheating element of a preset number of preheating items of at least one type.

[0079] In this implementation, for each of the first preset number of preheating elements in each preheating item, for example, the first three preheating elements, these three preheating elements can be used simultaneously to preheat the application program, and this process can improve the efficiency of preheating.

[0080] Furthermore, if the preheating operation on the application is not completed within a preset time period, the preheating operation on the application is stopped.

[0081] In this implementation, a time limit for executing the preheating operation, that is, a preset time, can be set. If the preheating operation is not fully completed within the preset time, entering the interactive interface of the application can be directly terminated.

[0082] For example, 2s, 3s, etc.

[0083] In a possible implementation, the preheating operation can be performed synchronously or in parallel based on Bootstrap, and the preheating time can be controlled by timeout configuration to avoid the risk of application unavailability due to excessive preheating operation cost.

[0084] In the preheating method for an application provided by an embodiment of the present invention, when the terminal device detects that an application is started, the terminal device obtains at least one type of preheating item; wherein each type of preheating item includes: a pre-preset number of preheating elements with a usage frequency from high to low under the type, and the preheating element is an element that requires preparation operation, verification operation, pre-calculation operation, or / and initialization operation before the application is run, and then the application is preheated according to at least one type of preheating item. In this technical solution, a pre-preset number of preheating elements with a usage frequency from high to low can be obtained, and a better resource strategy can be used at startup to improve the efficiency of the cold start in the preheating stage; then the obtained preheating elements can be used to preheat the application, so that in the subsequent application operation process, the user's business request can be quickly responded to, reducing business timeouts and other problems caused by cold start, and improving the availability, rapid response capability, and user experience of the application.

[0085] Based on the above embodiments, Figure 3 FIG. 1 is a flow chart showing a second embodiment of the preheating method applied in the present invention, which describes the above S21 in detail from the perspective of interaction between the terminal device and the service device. Figure 3 As shown, the following steps are included:

[0086] S31, the terminal device sends a preheating request to the service device corresponding to the application;

[0087] The preheating request is used to trigger the service device to determine a preset number of preheating elements with a usage frequency in descending order of at least one type of preheating items in the indicator warehouse;

[0088] In this step, when the terminal device detects that the application is started, the terminal device sends a preheating request to the service device corresponding to the application to request to obtain the preheating elements required for the preheating operation.

[0089] Optionally, the preheating request may carry an identifier of the terminal device;

[0090] In other implementations, the type of the preheating item and the number of preheating elements corresponding to each type may also be carried.

[0091] For example, the type of the preheating item to be obtained is an interface verification type, and the number of preheating elements to be obtained is 5.

[0092] S32, the service device obtains a preheating request sent by the terminal device on which the application is installed;

[0093] In this step, after the terminal device sends the preheating request, the service device obtains the preheating request.

[0094] S33, the service device determines, according to the preheating request, a preset number of preheating elements of at least one type of preheating items in the indicator warehouse of the service device, with the usage frequency ranging from high to low;

[0095] Among them, the indicator warehouse records the usage frequency of each preheating element in different types of preheating items.

[0096] In this step, after obtaining the preheating request, the service device determines at least one type of preheating item in the local indicator warehouse, and selects a preset number of preheating elements in each type of preheating item from high to low usage frequency.

[0097] For example, for a warm-up item of interface verification type, the top five API interfaces with the highest to lowest usage frequency can be obtained; for a warm-up item of database script type, the top ten SQLs with the highest to lowest usage frequency can be obtained, and so on.

[0098] In other implementations, if the preheating request carries the type of preheating item to be obtained as an interface verification type, and the number of preheating elements to be obtained is 5, then the top 5 API interfaces with the highest to lowest usage frequency are obtained from the preheating items of the interface verification type.

[0099] S34, the service device sends a preset number of preheating elements of at least one type of preheating item in descending order of usage frequency to the terminal device;

[0100] In this step, after determining a first preset number of preheating elements with a usage frequency from high to low in at least one type of preheating items, the preheating elements are sent to the terminal device.

[0101] S35. The terminal device receives a preset number of preheating elements of at least one type of preheating items sent by the service device, with the usage frequency ranging from high to low.

[0102] In this step, the terminal device receives the preheating element returned from the service device and then performs a preheating operation.

[0103] In an embodiment of the present invention, in a possible implementation, taking the database script type as an example: the application starts bootstrap to pull the top 20 frequently used SQLs from the indicator warehouse through a remote procedure call (RPC), and preheats these frequently used SQLs through ShardingSphereSqlWarmuper.

[0104] The preheating method of the application provided by the embodiment of the present invention, the terminal device sends a preheating request to the service device corresponding to the application; wherein the preheating request is used to trigger the service device to determine the pre-set number of preheating elements with the highest to lowest frequency of use in at least one type of preheating item in the indicator warehouse; then the service device obtains the preheating request sent by the terminal device on which the application is installed; then the service device determines the pre-set number of preheating elements with the highest to lowest frequency of use in at least one type of preheating item in the indicator warehouse of the service device according to the preheating request; wherein the indicator warehouse records the frequency of use of each preheating element in different types of preheating items, and then the service device sends the pre-set number of preheating elements with the highest to lowest frequency of use in at least one type of preheating item to the terminal device; finally, the terminal device receives the pre-set number of preheating elements with the highest to lowest frequency of use in at least one type of preheating item sent by the service device. In this technical solution, the service device pre-stores the pre-set number of preheating elements with the highest to lowest frequency of use in at least one type of preheating item, so as to achieve the purpose of allocating the preheating elements used when the application is cold started, thereby improving the accuracy of the current preheating business response for the subsequent application runtime.

[0105] Based on the above embodiments, Figure 4 The flowchart of the third embodiment of the preheating method applied by the present invention is shown. The method describes in detail the relevant implementation of the collection of usage information of the preheating element from the perspective of the interaction between the terminal device and the service device. Figure 4 As shown, the following steps are included:

[0106] S41. When the terminal device detects that the application is running, it obtains the usage log of the application;

[0107] The usage log records usage information of at least one preheating element during the running phase of the application program;

[0108] In this step, when the application is running, the terminal device continuously generates a usage log, and the usage log records the relevant usage information of the preheating elements involved when the application is running.

[0109] Optionally, the usage information may be, for example, the number of calls to A's SQL query interface; the number of calls to B's SQL; the number of calls to hotspot code C, and so on.

[0110] In a possible implementation, the frequency of obtaining the application usage log can be set, such as once a day, every time the application is used, and so on.

[0111] S42, the terminal device sends a usage log to the service device;

[0112] Among them, the usage log is used to determine the usage frequency of each warm-up element in different types of warm-up items in the indicator warehouse.

[0113] In this step, after obtaining the usage log, the terminal device sends the usage log to the service device.

[0114] In a possible implementation, the frequency of reporting the usage log of the application to the service device may be consistent with the frequency of obtaining the usage log, or a longer period may be used.

[0115] S43, the service device obtains the usage log of the application sent by the terminal device;

[0116] Optionally, in actual implementation, the number of terminal devices on which the application is installed is at least one, that is, in this step, for each terminal device, when the application is running, the corresponding usage log can be obtained at a certain frequency.

[0117] S44. The service device determines the usage frequency of at least one preheating element according to the acquired usage log, and stores it in the indicator warehouse.

[0118] In this step, after obtaining the usage log of the terminal device, the usage log is parsed to obtain usage information of the preheating element involved in the usage log;

[0119] For each preheating element, based on the usage information, the usage frequency of the preheating element is determined. The determination here can be divided into two cases:

[0120] 1. If the preheating element does not exist in the indicator warehouse, a new statistic for the preheating element can be created, and the usage frequency can be used as the usage frequency after the preheating element statistics; if the usage frequency of the preheating element exists in the indicator warehouse, the usage frequency of the preheating element statistics can be updated using the obtained usage frequency.

[0121] In one possible implementation, if it is parsed that the API interface for calling the product list is used 5 times in one day, 5 times can be added to the usage frequency of the API interface for calling the product list in the indicator warehouse; if it is parsed that the SQL query interface of A is used 3 times in one day, if there is no SQL query interface of A in the indicator warehouse, then the SQL query interface of A is created and the usage frequency is recorded as 3 times.

[0122] In addition, the usage frequency of unchanged preheating components can also be updated periodically. For example, if no new usage information is received within 10 days after calling the API interface for the product list, it can be considered that the business corresponding to the API interface for calling the product list is offline, and the usage frequency of the API interface for calling the product list and other related information can be cleared from the indicator warehouse.

[0123] In an embodiment of the present invention, in a possible implementation, taking the database script type as an example above: when the application is running, the SQL parser (English: Parser) interface performs syntax tree parsing on the SQL involved to obtain standardized SQL, and then reports the standardized SQL to the indicator warehouse based on the MeterReporter interface, so that the indicator warehouse can be used for frequency statistics of preheating elements of the database script type, that is, SQL statistics.

[0124] In the application preheating method provided by the embodiment of the present invention, when the terminal device detects that the application is running, it obtains the usage log of the application; wherein the usage log records the usage information of at least one preheating element during the running stage of the application; then the terminal device sends the usage log to the service device; then the service device obtains the usage log of the application sent by the terminal device; finally, the service device determines the usage frequency of at least one preheating element based on the usage information of at least one preheating element obtained, and stores it in the indicator warehouse.
