Description

Technical Field

[0001] The present invention relates to the field of cloud technology, and in particular to a double-buffer method, device, equipment and storage medium based on an asynchronous decorator. Background Art

[0002] With the development of technology, caching has become a technology widely used in computers to improve performance. In the context of Web applications, caching is used to retain pages or data between HTTP requests and use them multiple times without creating new ones. Its purpose is to save application processing time and resources.

[0003] Tornado is an open source version of a web server and its common tools. Tornado is significantly different from the current mainstream web server frameworks. Tornado is a non-blocking server and is quite fast. Based on Tornado's asynchronous function, Tornado can handle thousands of connections per second, so Tornado is an ideal framework for real-time web services.

[0004] However, the asynchronous call function involves concepts such as asynchrony, coroutines, concurrency, and non-blocking, which increases the requirements for development. In addition, it is extremely troublesome to use the Tornado framework to cache calls from the data layer, and there is not even a corresponding cache at the task layer. The efficiency of caching data through such a caching mechanism is low. Summary of the invention

[0028] The present invention provides a double cache method based on asynchronous decorator, which is used to construct asynchronous decorators in task layer and data layer, extract cache data through asynchronous decorators, solve the problem of complex calling target data from data layer, and improve cache efficiency.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0031] See also Figure 1 , an embodiment of the double buffering method based on asynchronous decorator in an embodiment of the present invention includes:

[0032] 101. Obtain data extraction instructions, and generate a target task layer asynchronous decorator according to the data extraction instructions.

[0033] The server obtains the data extraction instruction and generates a target task layer asynchronous decorator according to the data extraction instruction.

[0034] The server extracts instructions based on the data and uses the preset decorator to build a synchronous decorator at the preset task layer to obtain a task layer synchronous decorator. The server builds an asynchronous decorator at the preset task layer based on the task layer synchronous decorator to obtain an initial task layer asynchronous decorator. At this time, the initial task layer asynchronous decorator does not have asynchronous function. The server needs to use the preset asynchronous module and the preset asynchronous function to implement the asynchronous function of the initial task layer asynchronous decorator, and finally obtain the target task layer asynchronous decorator.

[0035] It should be noted that the preset business layer belongs to the upper structure, that is, the logic layer, and can run business logic; in this embodiment, the preset decorator is a decorator decorator in the Python language.

[0036] 102. According to the target task layer asynchronous decorator and preset construction rules, obtain the first target data key-value pair, the first target data key-value pair is composed of a parent class identifier and a child class identifier, and the parent class identifier and the child class identifier are extracted according to the data extraction instruction.

[0037] The server obtains the first target data key-value pair according to the target task layer asynchronous decorator and preset construction rules. The first target data key-value pair consists of a parent class identifier and a child class identifier. The parent class identifier and the child class identifier are extracted according to the data extraction instruction.

[0038] The server obtains the parent class identifier and the subclass identifier according to the target task layer asynchronous decorator and the data extraction instruction, and obtains the first target data key-value pair according to the preset construction rules, the parent class identifier and the subclass identifier. For example, if the data extraction instruction is to obtain an article, the article category is technology, and the author of the article is A, then the server first obtains the parent class identifier as article, the subclass identifier as technology, and the author A through the target task layer asynchronous decorator, then the parent class identifier article and the subclass identifier technology, author A constitute the first target data key-value pair.

[0039] 103. Obtain the first target data in the first cache space through the target task layer asynchronous decorator, and determine whether the first target data is a null value through the target task layer asynchronous decorator, where the first target data is data corresponding to the first target data key-value pair.

[0040] The server obtains the first target data in the first cache space through the target task layer asynchronous decorator, and determines whether the first target data is a null value through the target task layer asynchronous decorator. The first target data is the data corresponding to the first target data key-value pair.

[0041] The server obtains the first target data corresponding to the first target data key-value pair in the first cache space through the target task layer asynchronous decorator, and determines whether the first target data corresponding to the first target data key-value pair is a null value through the target task layer asynchronous decorator. If the first target data is not a null value, the server directly sends the first data as the target data to the preset terminal; if the first target data is a null value, it means that the first target data is not the target data, and it is necessary to re-acquire the target data from other cache spaces and send it to the preset terminal.

[0042] 104. If the first target data is a null value, forward the data extraction instruction to the preset data layer to obtain the second target data key-value pair, obtain the second target data in the second cache space, and determine whether the second target data is a null value. The second target data is the data corresponding to the second target data key-value pair.

[0043] If the first target data is a null value, the server forwards the data extraction instruction to the preset data layer to obtain the second target data key-value pair, obtains the second target data in the second cache space, and determines whether the second target data is a null value. The second target data is the data corresponding to the second target data key-value pair.

[0044] After the server determines that if the first target data is a null value, the server constructs a second target data key-value pair through the target data layer asynchronous decorator according to the construction rules of the target task layer asynchronous decorator. The second target data key-value pair includes a parent class identifier and a child class identifier. The server obtains the parent class data that matches the parent class identifier in the second cache space according to the parent class flag, and obtains the child class data that matches the child class identifier in the second cache space according to the child class identifier, and synthesizes the parent class data and the child class data to obtain the second target data.

[0045] It should be noted that the difference between the second target data key-value pair constructed by the target data layer asynchronous decorator and the first target data key-value pair constructed by the target task layer asynchronous decorator is that the prefixes are different. For example, the second target data key-value pair with the parent class identified as article, the subclass identified as technology and author A is: dao:article:scienceandtechnology:A, while the first target data key-value pair with the parent class identified as article, the subclass identified as technology and author A is: handler:article:scienceandtechnology:A.

[0046] 105. If the second target data is a null value, forward the second target data key-value pair to a database, obtain the target data in the database according to the second target data key-value pair, and send the target data to a preset terminal.

[0047] If the second target data is a null value, the server forwards the second target data key-value pair to the database, obtains the target data in the database according to the second target data key-value pair, and sends the target data to the preset terminal.

[0048] After judgment by the server, if the second target data is a null value, the server forwards the second target data key-value pair to the database, the server searches for the target data corresponding to the second target key-value pair in the database, extracts the target data into the second cache space first, and after judging that the target data in the second cache space is not a null value, extracts the target data into the first cache space, and after judging that the target data in the first cache space is not a null value, sends the target data to the preset terminal.

[0049] The embodiment of the present invention constructs an asynchronous decorator at the task layer and the data layer, extracts cache data through the asynchronous decorator, solves the problem of complex calling target data from the data layer, and improves cache efficiency.

[0050] See also Figure 2 Another embodiment of the double buffering method based on asynchronous decorator in the embodiment of the present invention includes:

[0051] 201. Construct a synchronization decorator at the preset task layer according to the data extraction instruction to obtain a task layer synchronization decorator.

[0052] The server constructs a synchronization decorator at the preset task layer according to the data extraction instruction to obtain the task layer synchronization decorator.

[0053] It should be noted that the preset business layer belongs to the upper structure, that is, the logic layer, and can run business logic; in this embodiment, the preset decorator is a decorator decorator in the Python language.

[0054] 202. Construct an asynchronous decorator in the preset task layer based on the task layer synchronous decorator to obtain an initial task layer asynchronous decorator.

[0055] The server constructs an asynchronous decorator at the preset task layer based on the task layer synchronous decorator to obtain an initial task layer asynchronous decorator.

[0056] The server builds an asynchronous decorator on the preset task layer based on the task layer synchronous decorator to obtain the initial task layer asynchronous decorator. At this time, the initial task layer asynchronous decorator does not have asynchronous function. The server needs to use preset asynchronous module and preset asynchronous function to implement the asynchronous function of the initial task layer asynchronous decorator, and finally obtain the target task layer asynchronous decorator.

[0057] 203. Process the initial task layer asynchronous decorator through the preset asynchronous module and the preset asynchronous function to obtain the target task layer asynchronous decorator.

[0058] The server processes the initial task layer asynchronous decorator through the preset asynchronous module and the preset asynchronous function to obtain the target task layer asynchronous decorator.

[0059] After obtaining the initial task layer asynchronous decorator, the initial task layer asynchronous decorator does not have asynchronous functionality, that is, it cannot process the second event while processing the first event. Therefore, the server needs to process the initial task layer asynchronous decorator through the preset asynchronous module and the preset asynchronous function to obtain the target task layer asynchronous decorator. At this time, the target task layer asynchronous decorator has asynchronous functionality and can process the second event while processing the first event.

[0060] 204. According to the target task layer asynchronous decorator and preset construction rules, obtain a first target data key-value pair, the first target data key-value pair is composed of a parent class identifier and a child class identifier, and the parent class identifier and the child class identifier are extracted according to the data extraction instruction.

[0061] The server obtains the first target data key-value pair according to the target task layer asynchronous decorator and preset construction rules. The first target data key-value pair consists of a parent class identifier and a child class identifier. The parent class identifier and the child class identifier are extracted according to the data extraction instruction.

[0062] Specifically, the server obtains the parent class identifier and the child class identifier according to the target task layer asynchronous decorator and the data extraction instruction; the server constructs a key-value pair of the parent class identifier and the child class identifier according to the preset construction rules and the asynchronous decorator to obtain the first target data key-value pair.

[0063] The server obtains the parent class identifier and the subclass identifier according to the target task layer asynchronous decorator and the data extraction instruction, and obtains the first target data key-value pair according to the preset construction rules, the parent class identifier and the subclass identifier. For example, if the data extraction instruction is to obtain an article, the article category is technology, and the author of the article is A, then the server first obtains the parent class identifier as article, the subclass identifier as technology, and the author A through the target task layer asynchronous decorator, then the parent class identifier article and the subclass identifier technology, author A constitute the first target data key-value pair.

[0064] The server constructs a key-value pair of the obtained attached column identifier and subclass identifier according to the preset construction rule and the asynchronous decorator to obtain the first target data key-value pair, namely Key. The first target data key-value pair is a string. The preset construction rule can be parent class identifier: subclass identifier, and the parent class identifier and the subclass identifier are separated by a colon. For example, the first target data key-value pair with the parent class identifier being article, the subclass identifier being technology and the author A is handler:article:scienceandtechnology:A.

[0065] It should be noted that the parent class identifier and the subclass identifier are determined according to the data extraction instruction. The parent class identifier can be a business name, type name or database name, etc., and the subclass identifier can be a function name, parameter name or parameter value, etc.

[0066] 205. Obtain the first target data in the first cache space through the target task layer asynchronous decorator, and determine whether the first target data is a null value through the target task layer asynchronous decorator, where the first target data is data corresponding to the first target data key-value pair.

[0067] The server obtains the first target data in the first cache space through the target task layer asynchronous decorator, and determines whether the first target data is a null value through the target task layer asynchronous decorator. The first target data is the data corresponding to the first target data key-value pair.

[0068] Optionally, the server obtains the first target data in the first cache space through the target task layer asynchronous decorator, and determines whether the first target data is a null value through the target task layer asynchronous decorator. The first target data is the data corresponding to the first target data key-value pair and also includes: if the first target data is not a null value, the server determines that the first target data is the target data, and sends the target data to the preset front end.

[0069] The server obtains the first target data corresponding to the first target data key-value pair in the first cache space through the target task layer asynchronous decorator, and determines whether the first target data corresponding to the first target data key-value pair is a null value through the target task layer asynchronous decorator. If the first target data is not a null value, the server directly sends the first data as the target data to the preset terminal; if the first target data is a null value, it means that the first target data is not the target data, and it is necessary to re-acquire the target data from other cache spaces and send it to the preset terminal.

[0070] 206. If the first target data is a null value, forward the data extraction instruction to the preset data layer to obtain the second target data key-value pair, obtain the second target data in the second cache space, and determine whether the second target data is a null value. The second target data is the data corresponding to the second target data key-value pair.

[0071] If the first target data is a null value, the server forwards the data extraction instruction to the preset data layer to obtain the second target data key-value pair, obtains the second target data in the second cache space, and determines whether the second target data is a null value. The second target data is the data corresponding to the second target data key-value pair.

[0072] After the server determines that if the first target data is a null value, the server constructs a second target data key-value pair according to the parent class identifier and the child class identifier through the target data layer asynchronous decorator according to the construction rules of the target task layer asynchronous decorator. The server obtains the parent class data that matches the parent class identifier in the second cache space according to the parent class flag, and obtains the child class data that matches the child class identifier in the second cache space according to the child class identifier, synthesizes the parent class data and the child class data, and obtains the second target data.

[0073] It should be noted that the difference between the second target data key-value pair constructed by the target data layer asynchronous decorator and the first target data key-value pair constructed by the target task layer asynchronous decorator is that the prefixes are different. For example, the second target data key-value pair with the parent class identified as article, the subclass identified as technology and author A is: dao:article:scienceandtechnology:A, while the first target data key-value pair with the parent class identified as article, the subclass identified as technology and author A is: handler:article:scienceandtechnology:A.

[0074] Specifically, the server obtains the target data layer asynchronous decorator through the data extraction instruction; the server obtains the second target data key-value pair through the target data layer asynchronous decorator, the data extraction instruction and the preset construction rule; the server obtains the parent class data corresponding to the parent class identifier in the second cache space according to the second target data key-value pair; the server obtains the subclass data corresponding to the subclass identifier in the second cache space according to the second target data key-value pair; the server synthesizes the parent class data and the subclass data to obtain the second target data, and determines whether the second target data is a null value through the target data layer asynchronous decorator.

[0075] For ease of understanding, the following is an explanation based on specific application scenarios:

[0076] The server obtains the parent class data matching the parent class identifier in the second cache space according to the second target data key-value pair, and obtains the subclass data matching the subclass identifier in the second cache space according to the parent class data. For example, the server obtains the article data corresponding to article according to the second target data key-value pair dao:article:science and technology:A, obtains the scientific article data corresponding to science and technology according to the second target data key-value pair dao:article:science and technology:A, and obtains the author data corresponding to A according to the second target data key-value pair dao:article:science and technologyA. The server synthesizes the article data, the scientific article data, and the author data to obtain the second target data, and the second target data is the scientific article data whose author is A.

[0077] The server obtains the second target data based on the parent class data and the child class data, and determines whether the second target data is a null value. If the second target data is not a null value, the second target data is set to the first cache space, the target data is obtained, and the target data is sent to the preset terminal; if the second target data is a null value, it means that the second target data is not the target data, and the target data needs to be obtained from the database and sent to the preset terminal.

[0078] Specifically, the server obtains the target data layer asynchronous decorator through data extraction instructions, including: the server obtains the target data layer asynchronous decorator through data extraction instructions, builds a synchronous decorator in the preset data layer according to the data extraction instructions, and obtains the data layer synchronous decorator; the server builds an asynchronous decorator based on the data layer synchronous decorator to obtain an initial data layer asynchronous decorator; the server processes the initial data layer asynchronous decorator through a preset asynchronous module and a preset asynchronous function to obtain a target data layer asynchronous decorator.

[0079] The server constructs a synchronous decorator on the preset data layer according to the data extraction instruction and uses the preset decorator to obtain the data layer synchronous decorator. The server constructs an asynchronous decorator on the preset data layer based on the data layer synchronous decorator to obtain the initial data layer asynchronous decorator. At this time, the initial data layer asynchronous decorator does not have asynchronous function. The server needs to use the preset asynchronous module and the preset asynchronous function to implement the asynchronous function of the initial data layer asynchronous decorator, and finally obtain the target data layer asynchronous decorator.

[0080] 207. If the second target data is a null value, forward the second target data key-value pair to a database, obtain the target data in the database according to the second target data key-value pair, and send the target data to a preset terminal.

[0081] If the second target data is a null value, the server forwards the second target data key-value pair to the database, obtains the target data in the database according to the second target data key-value pair, and sends the target data to the preset terminal.

[0082] Specifically, the server determines the first transition target data in the database through the second target data key-value pair; the server sets the first transition target data in the second cache space through the target data layer asynchronous decorator to obtain the second transition target data; the server sets the second target transition data in the first cache space through the target task layer asynchronous decorator to obtain the third transition target data; the server determines the third transition target data as the target data, and sends the target data to the preset front end.

[0083] It should be noted that the first transition target data is the data in the database that matches the second target data key-value pair, the second transition target data is the data in the second cache space that matches the second target data key-value pair, and the third transition target data is the data in the first cache space that matches the first target data key-value pair.

[0084] After judgment by the server, if the second target data is a null value, the server determines the first transition target data in the database based on the second target data key-value pair. After determining that the first transition target data is not a null value, the server sets the first transition target data in the second cache space. At this time, the second transition target data is obtained. The server then sets the second transition target data in the first cache space. After determining that the second transition target data is not a null value, the third transition target data is obtained, and the third transition target data is determined as the target data. Finally, the server sends the third transition target data to the preset terminal.
