Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular, to a cache preheating method, apparatus, electronic device, and storage medium. Background Art

[0002] Cache technology is an important means for various application services or software to improve service performance. In the normal mode, the configuration cache data of various application services is generally loaded during the startup process of the application service, and the cache data related to the business is generally loaded into the cache when the user accesses it for the first time. This process is also called the cache preheating of the system. This mode can improve the query efficiency of subsequent access queries, but the time required for the first access will increase. This is also the reason why most systems are slow to access when they are just started, and the overall response time will improve after the service for a period of time. However, in some scenarios where new application services need to be enabled, due to the too long system preheating time of the new application service, the overall service performance of the application service is poor and cannot meet the user's business needs.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0024] Figure 1 FIG. is a schematic flowchart of a cache preheating method provided by an embodiment of the present invention. This embodiment is applicable to scenarios of primary and standby service node switching and / or new service node addition. This method can be executed by a cache preheating device provided by an embodiment of the present invention, and this device can be implemented in software and / or hardware. In a specific embodiment, this device can be integrated in an electronic device, such as a computer, a server, etc. The following embodiments will be described by taking this device integrated in an electronic device as an example. Refer to Figure 1 , and the method can specifically include the following steps:

[0025] Step 101, obtain a cache access request sent by a business application to the current service node. This step is conducive to generating a cache preheating task based on the cache access request.

[0026] Specifically, the above-mentioned current service node can be understood as an application service node that is currently providing services for a business application. Specifically, for example, the primary service node in a hot standby service node.

[0027] Optionally, the above cache access request includes: a data access request for accessing local cache data in the application service layer, database cache data in the data layer, and / or middleware cache data in the middleware layer of the current service node. It can be understood that most fully functional application services generally include an application service layer and a database layer. Application services developed based on a microservices architecture with multi-node deployment generally also include a middleware layer. Making a cache access request to at least one of the application service layer, database layer, and middleware layer to obtain corresponding cached data, and further preheating the target node's cache data can reduce the time required for cache preheating of the system of the newly added service node.

[0028] Optionally, the cache data in the above application service layer includes: configuration data, parameter data, basic user information, and / or business data frequently queried.

[0029] Optionally, the cache data in the above database layer includes: SQL (Structured Query Language) statements frequently executed, compiled SQL statements, and / or SQL result sets frequently queried.

[0030] Optionally, the middleware layer cache data includes user login authentication information and / or business data cached to improve performance.

[0031] Optionally, the process of obtaining the cache access request sent by the business application to the current service node includes: obtaining the corresponding cache access request in real time when the business application sends a cache access request to the current service node.

[0032] Specifically, step 101 can be executed by the current service node or by an application preheating service node independent of the current service node.

[0033] Optionally, when step 101 is executed by the above application preheating service node, the process of obtaining the cache access request sent by the business application to the current service node includes: obtaining the cache access request from the location where the cache access request sent by the business application to the current service node is stored.

[0034] Specifically, the above cache access request can be collected by a cache access request collection tool integrated in the current service node and then output to the corresponding storage location.

[0035] Optionally, the process of obtaining the corresponding cache access request from the location where the cache access request sent by the business application to the current service node is stored includes: obtaining the above cache access request from the corresponding storage location based on the cache preheating period of the business application.

[0036] Optionally, the process of obtaining the corresponding cache access request from the location storing the cache access request sent by the business application to the current service node includes: when the resource utilization rate of the current service node is not less than a preset ratio, generating a cache warm-up task based on the cache access request.

[0037] Step 102, generating a cache warm-up task based on the cache access request. This step can facilitate cache warm-up of the target service node based on the cache warm-up task.

[0038] Specifically, step 102 can be executed by the current service node or by the aforementioned application warm-up service node.

[0039] Optionally, the process of generating a cache warm-up task based on the cache access request includes: when the resource utilization rate of the current service node is not less than a preset ratio, generating a cache warm-up task based on the cache access request.

[0040] Specifically, the aforementioned preset ratio can be set based on empirical data, for example, it can be set to 60%-80%.

[0041] Specifically, a cache warm-up task can be generated based on the cache access request when the resource utilization rate of the current service node is not less than the preset ratio and the resource utilization rate of the current service node is still increasing.

[0042] In a specific example, the current service node is 2 primary service nodes of a primary / backup mode common basic service, and 1 backup service node is deployed for this common basic service. The backup service node will be automatically enabled after the resource usage of the common basic service exceeds 80% on each primary service node. Then, when the resource usage of each primary service node is not less than 60%, a cache warm-up task is generated based on the cache access request.

[0043] Specifically, a cache warm-up task can also be generated in real time based on the aforementioned cache access request.

[0044] Optionally, the process of generating a cache warm-up task based on the cache access request includes: replacing the network address in the cache access request with the network address of the target service node to obtain the aforementioned cache warm-up task.

[0045] Step 103, performing cache warm-up on the target service node based on the cache warm-up task. Based on steps 101 and 102, this step can realize preloading of the target service node cache by obtaining the cache access request sent by the business application to the current service node and generating a cache warm-up task based on the cache access request to perform cache warm-up on the target service node, so as to reduce the time required for cache warm-up of the system of the newly added service node when enabling a new service node, improve the overall service performance of the application service, meet user requirements, and improve user experience.

[0046] Specifically, step 103 can be executed by the current service node or by the aforementioned application warm-up service node.

[0047] Optionally, the process of preheating the cache of the target service node based on the cache warm-up task includes: sending the cache warm-up task to the target service node to request access to the cache data of the target service node.

[0048] Optionally, the above-mentioned target service node includes: a standby service node in the hot standby service node, and / or a newly added service node.

[0049] Specifically, in the scenario of switching between the primary and standby service nodes and the scenario of a sharp increase in user traffic requiring rapid expansion of newly added service nodes, the system warm-up duration of the standby service and the newly added service nodes directly affects the overall service performance of the application service. Therefore, preheating the cache of the standby service node and the newly added service node based on the cache warm-up task corresponding to the cache access request of the current service node can help reduce the time required for preheating the cache of the corresponding service node system.

[0050] The following further introduces the cache warm-up method provided by the embodiments of the present invention.

[0051] Optionally, as Figure 2 shown, the cache warm-up method provided by the embodiments of the present invention includes the following steps:

[0052] Step 201, mark the interface code that the business application needs to call to access the cache data of the current service node as cache access code.

[0053] Optionally, the process of marking the interface code that the business application needs to call to access the cache data of the current service node as cache access code includes: based on aspect-oriented programming technology, mark the interface code that the business application needs to call to access the cache data of the current service node as cache access code.

[0054] Specifically, other methods in the prior art can also be used to mark the interface code that the business application needs to call to access the cache data of the current service node as cache access code.

[0055] In an optional specific example, the process of marking the interface code that the business application needs to call to access the cache data of the current service node as cache access code based on aspect-oriented programming technology (Spect Oriented Programming, AOP) can be implemented by a cache access request collection tool integrated in the current service node.

[0056] In an actual application scenario, after completing the development of all functions of the current service node, the code points for the current service node to load local cache data, middleware cache data, and database cache data and the interfaces for calling the code can be confirmed, and the above cache access request collection tool can be introduced into the current service node.

[0057] Optionally, the process of marking the interface code that the business application needs to call to access the cache data of the current service node as cache access code based on aspect-oriented programming technology includes: using the cache access request collection tool based on aspect-oriented programming technology to add annotations defined by the cache access request collection tool at the interface code where the business application code will gradually call to execute the local cache loading and middleware cache loading, and at the interface code where the business application gradually calls to execute the high-frequency SQL or performance bottleneck SQL for database access.

[0058] Specifically, for example, after annotating the interface code "queryInfo(){}", the code at the corresponding position is obtained as "@collecturl public void queryInfo(){}".

[0059] Optionally, the process of marking the interface code that the business application needs to call to access the cache data of the current service node as cache access code based on aspect-oriented programming technology includes: using the cache access request collection tool to configure the corresponding interface code in the configuration file based on aspect-oriented programming technology.

[0060] Specifically, for example, for the interface code "queryInfo(){}", it can be configured in the configuration file in the following format: "collectURLList=ClassA.queryInfo".

[0061] Step 202, collect the data access requests for calling the cache access code to obtain cache access requests.

[0062] In an actual application scenario, after the current service node is started, the above cache access request collection tool automatically starts a thread to collect the data access requests for calling the cache access code based on a pre-defined information collection format to obtain the above cache access requests.

[0063] Specifically, the above information collection format can be, for example:

[0064] [Cache type LocalCache / RedisCache / DBCache|Interface information|Full URL request|User identification information|Collection time]

[0065] Step 203, generate cache warm-up tasks based on the cache access requests.

[0066] Step 204, perform cache warm-up on the target service node based on the cache warm-up task.

[0067] The embodiments of the present invention can conveniently and efficiently collect cache access requests without affecting the business of the current service node.

[0068] Next, the cache warm-up method provided by the embodiments of the present invention is further introduced.

[0069] Optionally, as Figure 3 shown, the cache warm-up method provided by the embodiments of the present invention includes the following steps:

[0070] Step 301, obtain a cache access request sent by a business application to the current service node.

[0071] Step 302, output the cache access request to the access request storage location.

[0072] Optionally, the process of outputting the cache access request to the access request storage location includes: outputting the cache access request to a pre-determined request storage location through the aforementioned cache access request collection tool.

[0073] Specifically, the aforementioned request storage location can be a shared file, a database, or a message queue.

[0074] Step 303, read cache access requests from the access request storage location based on the cache warm-up period corresponding to the business application, and generate a cache warm-up task based on the read cache access requests.

[0075] Specifically, before step 303, the acquisition method of the cache access request can be configured, specifically, the location for obtaining the cache access request and the aforementioned cache warm-up period can be configured.

[0076] Optionally, the process of configuring the location for obtaining the cache access request includes: configuring the IP address and port of the message queue where the cache access request is located; configuring the address of the shared file where the cache access request is located; or configuring the IP address, port, and table name of the database where the cache access request is located.

[0077] Specifically, before step 303, the target service node information can also be configured, specifically including the IP address and port of the target service node.

[0078] Optionally, the aforementioned target service node information can also include authentication information pre-negotiated with the target service node.

[0079] Specifically, before step 303, the generation of the cache warm-up task and the cache warm-up task distribution thread can also be configured.

[0080] Optionally, the process of reading the cache access request from the storage location of the access request in the cache warm-up period corresponding to the business application includes:

[0081] After the end of the previous cache warm-up period, read the above-mentioned cache access request for the most recent period from the storage location of the access request.

[0082] Specifically, the above cache warm-up period can be determined based on the business characteristics of the business application. For example, in an actual application scenario, when the business application usually accesses all cache data of the current service node within a week, set the above cache warm-up period to one week.

[0083] In a specific example, monitor the message queue where the cache access request is located, and after the message queue receives a message, read the cache access request from the corresponding message queue, and generate a cache warm-up task based on the read cache access request.

[0084] Specifically, the above cache warm-up period can also be determined based on the cache cleaning policy of the target service node.

[0085] Step 304, perform cache warm-up on the target service node based on the cache warm-up task.

[0086] In the embodiment of the present invention, by reading the cache access request and performing cache warm-up on the target service node according to the cache warm-up period corresponding to the business application, rather than performing real-time warm-up on the target service node according to the corresponding cache access request, it is possible to achieve preloading of the target service node cache on the premise of avoiding waste of resources.

[0087] Next, the cache warm-up method provided by the embodiment of the present invention will be further introduced.

[0088] Optionally, as Figure 4 shown, that is Figure 1 step 102 in

[0089] Step 1021, replace the network address in the cache access request with the network address of the target service node to obtain a cache warm-up request.

[0090] It can be understood that generally, the cache access request includes: the network address of the current service node + parameters; then the above cache warm-up request includes: the network address of the target service node + parameters.

[0091] Step 1022, add the network address and authentication information of the target service node to the cache warm-up request to obtain a cache warm-up task.

[0092] Specifically, the above cache warm-up task may include: cache warm-up request + authentication information + network address of the target service node.

[0093] Specifically, the above authentication information may be encrypted information negotiated with the target service node in advance, etc.

[0094] Optionally, the process of preheating the cache of the target service node based on the cache preheating task includes: sending the cache preheating task to the target service node through the network address of the target service node, so that the target service node performs a legality authentication on the cache preheating task based on the authentication information, and obtains a cache preheating request after the authentication is passed, and loads corresponding cache data based on the cache preheating request.

[0095] Specifically, by adding authentication information to the cache preheating request in the embodiments of the present invention, the target service node can perform a legality authentication on the cache preheating request to avoid the target service node from being illegally attacked.

[0096] Figure 5 It is a structural diagram of a cache preheating device provided by an embodiment of the present invention. This device is applicable to execute the cache preheating method provided by the embodiment of the present invention. As Figure 5 shown, the device may specifically include:

[0097] A cache access request acquisition module 501, configured to acquire a cache access request sent by a service application to the current service node, which is beneficial to generating a cache preheating task based on the cache access request.

[0098] Specifically, the cache access request acquisition module 501 may be integrated in the current service node or in an application preheating service node independent of the current service node.

[0099] A cache preheating task generation module 502, configured to generate a cache preheating task based on the cache access request, which is beneficial to preheating the cache of the target service node based on the cache preheating task.

[0100] Specifically, the above cache preheating task generation module 502 may be integrated in the current service node or in an application preheating service node independent of the current service node.

[0101] Optionally, the above cache preheating task generation module 502 can specifically be configured to generate a cache preheating task based on the cache access request when the resource utilization rate of the current service node is not less than a preset ratio.

[0102] Optionally, the above cache preheating task generation module 502 can specifically be configured to replace the network address in the cache access request with the network address of the target service node to obtain a cache preheating request; and add the network address and authentication information of the target service node to the cache preheating request to obtain a cache preheating task.

[0103] The preheating module 503 is used to perform cache preheating on the target service node based on the cache preheating task. Combining modules 501 and 502, it can obtain the cache access requests sent by the business application to the current service node, and generate cache preheating tasks based on the cache access requests to perform cache preheating on the target service node, enabling the preloading of the target service node's cache. This helps reduce the time required for cache preheating of the new service node system when enabling a new service node, improving the overall service performance of the application service to meet user needs and enhance the user experience.

[0104] Specifically, the above-mentioned preheating module 503 can be integrated into the current service node or into an application preheating service node independent of the current service node.

[0105] Optionally, the above-mentioned preheating module 503 can specifically be used to send the cache preheating task to the target service node through the network address of the target service node, so that the target service node performs a legality authentication on the cache preheating task based on the authentication information, and obtains the cache preheating request after the authentication passes, and loads the corresponding cache data based on the cache preheating request.

[0106] Optionally, the cache preheating device provided by the embodiment of the present invention further includes: a cache access code marking module, which is used to mark the interface code that the business application needs to call to access the cache data of the current service node as cache access code before obtaining the cache access request sent by the business application to the current service node.

[0107] Optionally, the above-mentioned cache access code marking module can specifically be used to mark the interface code that the business application needs to call to access the cache data of the current service node as cache access code based on the aspect-oriented programming technology.

[0108] Optionally, the aforementioned cache access request acquisition module 501 can specifically be used to collect the data access requests that call the cache access code to obtain the cache access request.

[0109] Optionally, the cache preheating device provided by the embodiment of the present invention further includes a request storage module, which is used to output the cache access request to the access request storage location before generating the cache preheating task based on the cache access request.

[0110] Optionally, the aforementioned cache preheating task generation module 502 can specifically be used to read the cache access request from the access request storage location based on the cache preheating period corresponding to the business application, and generate the cache preheating task based on the read cache access request.
