Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application.

At present, when obtaining data from the service system through paging query, users request data from the service system according to the filter conditions, and the service system generates paging query expression statements that the storage system can understand according to the filter conditions. If the storage system is Mysql, then The query expression can be a SQL statement. The storage system runs the SQL statement to obtain the paged data and returns it to the service system. Finally, the service system returns the paged data to the user to complete a paged query.

However, when users query data based on conditions, if the content of the data changes, the data obtained will be inaccurate when the user uses paging to query the data again. Take Mysql storage as an example to illustrate the reason for inaccuracy. The user’s one-time query condition is C ₁ =(c=apple), the paging condition is P ₁ =(page=1, size=5), and there are document sets in the storage system that meet the query conditions U=(d ₁ ,d ₂ ,d ₃ ,...,d ₁₀ ) A total of 10 documents, according to the query condition C ₁ and the paging condition P _{1, the} service system generates the query condition sentence "where c ='apple' limit 0,5", and returns to the first page with 5 items The document set is U ₁ = (d ₁ , d ₂ , d ₃ , d ₄ , d ₅ ). At this time, if the user changes the attribute c of _{the document d 1 to} the "orange" after obtaining the data, the set _{meets the condition C 1} It will become U = (d ₂ , d ₃ ,..., d ₁₀ ) with a total of 9 documents. At this time, the user performs the second page-turning query, the query condition C ₁ = (c = apple), and the paging condition is P ₂ =(page=2, size=5), the generated query condition sentence is "where c='apple'limit 5,5", and the document set obtained is U ₂ ＝(d ₇ ,d ₈ ,d ₉ ,d ₁₀ ) observed for the first time and the second time query results due to changes in the document d ₁ shows the results led to two consecutive lost document d _6, greatly reducing the user's experience.

In response to the above problems, the inventor has discovered through long-term research, and proposed the paging data query method, device, electronic device, and storage medium provided by the embodiments of this application. The document identification sequence is stored through the snapshot storage module, and the document identification sequence is stored according to the paging query request. The query condition and the paging condition determine the correct document identification sequence from the document identification sequence to improve the accuracy and efficiency of the paging query. Among them, the specific paging data query method will be described in detail in the subsequent embodiments.

The following describes a schematic diagram of an environment that can be used in the paging data query method provided in the embodiments of the present application.

Please refer to FIG. 1. FIG. 1 shows a schematic diagram of an application environment that can be used for the paging data query method provided by the embodiments of the present application. It includes an electronic device (server) 100 and a user terminal 200, and the electronic device 100 and the user terminal 200 are in communication connection to implement data interaction. For example, the user terminal 200 may send a paging query request to the electronic device 100. Wherein, the electronic device 100 and the user terminal 200 can be connected via a data network or a wireless network. When the electronic device 100 and the user terminal 200 are connected via a data network, the electronic device 100 and the user terminal 200 can be connected via a 2G network, a 3G network, a 4G network, When the electronic device 100 and the user terminal 200 are connected through a wireless network, the electronic device 100 and the user terminal 200 can be connected through a wireless fidelity WiFi network, which is not limited here. Wherein, the electronic device 100 may be a tablet computer, a desktop computer, a server, etc., and the user terminal 200 may be a smart phone, a tablet computer, a wearable electronic device, etc., which are not limited herein.

The electronic device 100 may be loaded with a service system, and the service system may include a query engine module, a snapshot storage module, and a data storage module.

Among them, the query engine module can be responsible for the user to receive the paging query request sent by the user through the user terminal, and adaptively go to the data storage module or the snapshot storage module to query the document data and finally return it to the user terminal. In some implementations, the query engine module can have the following functions: (1) Responsible for receiving a paged query request sent by a user through a user terminal, and can generate a unique paged query state according to the paged query condition and the user ID in the paged query request; 2) According to the paging query status, it can be judged whether the data corresponding to the paging query status is directly obtained from the data storage module, or the document identification sequence is obtained from the snapshot storage module and then obtained from the data storage module; (3) It can be generated according to the paging query status The data storage module can understand query expressions and request data from the data storage module.

Among them, the snapshot storage module is used to store the document identification sequence corresponding to each paged query state. The storage mode uses computer memory for storage to ensure the efficiency of data query. In some embodiments, the snapshot storage module may have the following functions: (1) It can store data in the memory in the form of (key, value), that is, the corresponding document identification sequence can be obtained according to each page query state; (2) Support to specify the data expiration time according to the key, and the data will be automatically cleared after the time expires, thereby avoiding insufficient computer memory; (3) Supporting persistent storage of the data in the memory to the disk storage to avoid downtime of the machine where the snapshot storage module is located After the data is dropped.

In some embodiments, the data storage module may have the following functions: (1) have a fixed query logic expression; (2) support querying data in a paging query mode; (3) support establishing an index based on a certain field of the data.

Please refer to FIG. 2, which shows a schematic flowchart of a method for querying paging data provided by an embodiment of the present application. The paging data query method is used to store the document identification sequence through the snapshot storage module, and determine the correct document identification sequence from the document identification sequence according to the query conditions and the paging conditions in the paging query request, so as to improve the accuracy and efficiency of the paging query . In a specific embodiment, the paging data query method is applied to the paging data query device 300 as shown in FIG. 11 and the electronic device 100 equipped with the paging data query device 300 (FIG. 12 ). The following will take an electronic device as an example to describe the specific process of this embodiment. Of course, it is understandable that the electronic device applied in this embodiment may be a server, a tablet computer, a desktop computer, etc., which is not limited here. The process shown in Figure 2 will be described in detail below. In this embodiment, the electronic device is loaded with a service system. The service system shown includes a query engine module, a snapshot storage module, and a data storage module. The paging data query method may specifically include the following steps:

Step S110: The query engine module receives a paging query request, where the paging query request includes a query condition and a paging condition.

In some embodiments, the query engine module may receive a paged query request sent by a user through the user terminal, where the received paged query request may carry query conditions and paging conditions. Specifically, the query condition can be, for example, C=(c ₁ , c ₂ ,..., c _n ), where c _n represents the content of the query condition, n is a natural number, and the paging condition can be, for example, P=(page , Size), where page represents the current page number of data to be obtained, and size represents the number of data requested for a page.

In this embodiment, the query condition and the paging condition carried by the paging query condition may be pre-configured by the user terminal, or manually configured by the user. For example, the size in the paging condition can be pre-configured with a default value by the user terminal. For example, the default value of the size can be pre-configured by the user terminal. The size in the paging condition can also be configured by the user according to preferences or habits, such as when the user prefers When the number of data displayed on a page is 3, you can manually configure the size in the paging condition to 3, which is not limited here.

In some embodiments, the paging query request may be generated and sent to the query engine module when the user terminal receives a specified voice input, or may be generated and sent to the query engine module when the user terminal receives a specified touch operation, where Not limited.

Step S120: Obtain the document identification sequence corresponding to the query condition from the snapshot storage module as the first document identification sequence.

In some embodiments, after receiving the paging query request, the query engine module may analyze the paging query request, and extract the query conditions carried in the paging query request from the paging query request based on the analysis of the paging query request, and then based on the The query condition acquires the document identification sequence corresponding to the query condition from the snapshot storage module, and uses the acquired document identification sequence corresponding to the query condition as the first document identification sequence.

As a way, the snapshot storage module can obtain and record multiple query conditions and multiple document identification sequences in advance, and establish a mapping relationship between multiple query conditions and multiple document identification sequences, where the mapping relationship may be multiple One query condition corresponds to multiple document identification sequences, as shown in Table 1. Among them, when the query engine module obtains the query conditions, it can compare the obtained query conditions with multiple query conditions in the pre-established mapping relationship to obtain the query conditions that match the obtained query conditions, and then based on the mapping The relationship acquires the document identification sequence corresponding to the query condition that matches the acquired query condition. When determining the document identification sequence corresponding to the query condition that matches the acquired query condition, the document identification sequence may be determined as the first document identification sequence . Wherein, the first document identification sequence may be, for example, L=(k ₁ , k ₂ , k ₃ ,..., k _n ), where k _n is a specific value of the first document identification, and n is a natural number.

Table 1

查询条件Query conditions	文档标识序列Document identification sequence
查询条件1Query condition 1	文档标识序列1Document identification sequence 1
查询条件2Query condition 2	文档标识序列2Document identification sequence 2
查询条件3Query condition 3	文档标识序列3Document identification sequence 3

Step S130: Obtain a document identification sequence from the first document identification sequence as a second document identification sequence based on the paging condition.

In some embodiments, after receiving the paging query request, the query engine module may analyze the paging query request, and extract the paging condition carried by the paging query request from the paging query request based on the analysis of the paging query request, and then based on the paging The condition acquires the document identification sequence corresponding to the paging condition from the first document identification sequence, and uses the acquired document identification sequence corresponding to the paging condition as the second document identification sequence.

For example, if the first document identification sequence is L=(k ₁ , k ₂ , k ₃ ,..., k _n ), where k _n is the specific value of the first document identification, n is a natural number, and the paging condition is P=(page, size), then the query engine module can obtain the corresponding document identification sequence in the first document identification sequence L according to the paging condition P=(page, size), for example, the paging condition P=(page=1, size= 3), the starting position indicated by the paging condition can be calculated as Start=size*(page-1)+1=1, and the first document identification sequence L=(k ₁ , k ₂ , k _{3 is taken according to size=3} ,..., k _n ) in the document identification sequence L ₁ =(k ₁ , k ₂ , k ₃ ) as the second document identification sequence.

Step S140: Obtain and feed back target data corresponding to the second document identification sequence from the data storage module.

In some embodiments, after acquiring the second document identification sequence, the query engine module may acquire target data corresponding to the second document identification sequence from the data storage module based on the second document identification sequence, and feed back the acquired target data To the user terminal to complete a query and feedback of paging data. For example, when the second document identification sequence is L ₁ =(k ₁ , k ₂ , k ₃ ), then the second document identification sequence L ₁ =(k ₁ , k ₂ , k can be obtained from the data storage module ₃ ) Corresponding target data, and feedback the acquired target data to the user terminal. It is understandable that, in this embodiment, even when the user performs continuous paged query and modifies the query data, the document identification sequence stored in the snapshot storage module remains unchanged. Therefore, even if the user modifies the data, it will not appear. The situation of data missing, which greatly improves the accuracy of the user's data processing, and the snapshot storage method can also improve the efficiency of the user's data query.

In the paging data query method provided by one embodiment of the present application, a query engine module receives a paging query request, the paging query request includes a query condition and a paging condition, and a document identification sequence corresponding to the query condition is obtained from the snapshot storage module as the first document identification Sequence, obtain the document identification sequence from the first document identification sequence as the second document identification sequence based on the paging condition, obtain and feed back the target data corresponding to the second document identification sequence from the data storage module, thereby storing the document identification through the snapshot storage module Sequence, and determine the correct document identification sequence from the document identification sequence according to the query conditions and paging conditions in the paged query request, so as to improve the accuracy and efficiency of the paged query.

For the specific description of step S210, please refer to step S110, which will not be repeated here.

Step S220: Generate a query status identifier based on the query condition.

In this embodiment, after the query engine module obtains the query conditions carried in the paging query request, it can generate a query status identifier based on the query conditions, where the query status identifier is used to identify the paged query record of the user, for example, the query status The identifier is used to identify whether the user has performed a paged query based on the query condition, and whether the user obtains the document identification sequence from the snapshot storage module or directly obtains the data from the data storage module when the user performs a paged query based on the query condition, etc., which is not limited here.

In some implementations, the query engine module can analyze the paged query request after receiving the paged query request, and extract the paged query request from the paged query request based on the analysis of the paged query request for uniquely identifying the user. The user identifier is then generated based on the user identifier and the query conditions, and the query status identifier generated uniquely corresponds to the user corresponding to the user identifier.

Step S230: Obtain the document identification sequence corresponding to the query status identification from the snapshot storage module as the first document identification sequence.

As a way, the snapshot storage module can obtain and record multiple query status identifiers and multiple document identifier sequences in advance, and establish a mapping relationship between multiple query status identifiers and multiple document identifier sequences, where the mapping relationship can be There is a one-to-one correspondence between multiple query status identifiers and multiple document identifier sequences, as shown in Table 2. Wherein, when the query engine module obtains the query status identifier, it can compare the acquired query status identifier with multiple query status identifiers in the pre-established mapping relationship to obtain a query status that matches the acquired query status identifier. Identification, and then obtain the document identification sequence corresponding to the query state identifier that matches the acquired query state identifier based on the mapping relationship. When determining the document identification sequence corresponding to the query state identifier that matches the acquired query state identifier, the document can be The identification sequence is determined as the first document identification sequence.

Please refer to FIG. 4, which shows a schematic flow chart of step S230 of the paging data query method shown in FIG. 3 of the present application. The flow shown in FIG. 4 will be described in detail below. The method may specifically include the following step:

Step S231: Determine whether the snapshot storage module satisfies a specified condition based on the query status identifier.

In some embodiments, the electronic device may preset and store a designated condition, and the designated condition is used as a judgment basis for the snapshot storage module. Therefore, the snapshot storage module can be compared with the specified condition to determine whether the snapshot storage module meets the specified condition. In this embodiment, the query status identifier can be used as a parameter for judging whether the snapshot storage module meets the specified condition, that is, it can be based on Query the status flag to determine whether the snapshot storage module meets the specified conditions.

Step S232: When the snapshot storage module satisfies the specified condition, obtain the document identification sequence corresponding to the query status identification from the snapshot storage module as the first document identification sequence.

In some embodiments, when the judgment result indicates that the snapshot storage module satisfies the specified condition, the document identification sequence corresponding to the query status identification can be obtained from the snapshot storage module, and the obtained document identification sequence is used as the first document identification sequence. When the judgment result indicates that the snapshot storage module does not meet the specified condition, the data corresponding to the paging query request can be directly searched from the data storage module, and the searched data is fed back to the user terminal.

Step S240: Acquire a document identification sequence from the first document identification sequence as a second document identification sequence based on the paging condition.

For the specific description of step S240, please refer to step S130, which will not be repeated here.

Step S250: Generate a query sentence matching the data storage module based on the second document identification sequence.

In some embodiments, different data storage modules can recognize different query statements. For example, if the data storage module is Mysql, then the query statements that can be recognized by the data storage module are SQL. Therefore, in this embodiment, when the second document identification sequence is obtained, a query sentence matching the data storage module can be generated based on the second document identification sequence. It can be understood that the query sentence can be recognized by the data storage module, and The query sentence may be used to instruct the data storage module to query and feed back the target data corresponding to the second document identification sequence.

Please refer to FIG. 5. FIG. 5 shows a schematic flow chart of step S250 of the method for querying paging data shown in FIG. 3 of the present application. The flow shown in FIG. 5 will be described in detail below. The method may specifically include the following step:

Step S251: Determine the sentence format supported by the data storage module.

In some embodiments, the sentence format supported by the data storage module may be determined first, that is, the sentence format understood by the data storage module may be determined first. As a way, the attribute information of the data storage module can be obtained, and the sentence format supported by the data storage module can be determined based on the data information of the data storage module. For example, if the attribute information of the data storage module is Mysql, it can be determined that the statement format supported by the data storage module is SQL.

Step S252: Generate the query sentence based on the second document identification sequence, and the format of the query sentence is consistent with the sentence format supported by the data storage module.

In some embodiments, after the sentence format supported by the data storage module is determined, when the query sentence is generated based on the second document identification sequence, the format of the generated query sentence may be consistent with the sentence format supported by the data storage module to It is ensured that the query statement generated based on the second document identification sequence can be identified by the data storage module.

Step S260: Obtain and feed back target data corresponding to the second document identification sequence from the data storage module based on the query sentence.

In some embodiments, after obtaining the query sentence, the query engine module can send the query sentence to the data storage module to obtain the target data corresponding to the second document identification sequence from the data storage module based on the query sentence, and the target data The data is fed back to the user terminal.

The target data corresponding to the second document identification sequence is obtained from the data storage module based on the query sentence and fed back. Compared with the paging data query method shown in FIG. 2, this embodiment also generates a query status identifier based on query conditions, and obtains the corresponding document identifier sequence from the snapshot storage module based on the query status identifier, so as to improve the accuracy of obtaining the document identifier sequence. Sex.

Please refer to FIG. 6, which shows a schematic flowchart of a method for querying paging data according to another embodiment of the present application. The method is applied to the above-mentioned electronic equipment, and the electronic equipment is loaded with a service system. The service system shown includes a query engine module, a snapshot storage module, and a data storage module. The flow shown in FIG. 6 will be described in detail below. The paging data query method may specifically include the following steps:

Step S310: The query engine module receives a paging query request, and the paging query request includes a query condition and a paging condition.

For the specific description of step S310-step S320, please refer to step S210-step S220, which will not be repeated here.

Step S330: Determine whether the snapshot storage module includes a document identification sequence corresponding to the query status identification.

In this embodiment, after obtaining the query status identifier, the query engine module can determine whether the snapshot storage module includes a document identifier sequence corresponding to the query status identifier. In some implementations, after obtaining the query status identifier, the query engine module may compare the query status identifier with multiple query status identifiers in the pre-established preset relationship to determine whether the preset mapping relationship includes and acquired The query status identifier is consistent with the query status identifier.

Wherein, when the judgment result indicates that the preset mapping relationship does not include the query status identifier consistent with the acquired query status identifier, it can be determined that the snapshot storage module does not include the document identifier sequence corresponding to the query status identifier. When the judgment result indicates that the preset mapping relationship includes a query state identifier that is consistent with the acquired query state identifier, it can continue to determine whether there is a document identification sequence corresponding to the query state identifier that is consistent with the acquired query state identifier in the mapping relationship. When the judgment result indicates that there is no document identification sequence corresponding to the query state identifier that is consistent with the acquired query state identifier in the mapping relationship, it can be determined that the snapshot storage module does not include the document identification sequence corresponding to the query state identifier. When the judgment result is represented in the There is a document identification sequence corresponding to the query state identifier that is consistent with the acquired query state identifier in the mapping relationship, and it can be determined that the snapshot storage module includes the document identification sequence corresponding to the query state identifier.

Step S340: When the snapshot storage module includes the document identification sequence corresponding to the query status identifier, obtain the document identification sequence corresponding to the query status identifier from the snapshot storage module as the first document identification sequence.

In some embodiments, when the judgment result characterizes that the snapshot storage module includes a document identification sequence corresponding to the query status identifier, the characterization may obtain the document identification sequence from the snapshot storage module to improve the accuracy of the requested data acquisition. Therefore, in this embodiment, when the judgment result indicates that the snapshot storage module includes a document identification sequence corresponding to the query status identifier, the document identification sequence corresponding to the query status identifier can be obtained from the snapshot storage module, and the acquired document The identification sequence serves as the first document identification sequence.

Step S350: when the snapshot storage module does not include the document identification sequence corresponding to the query status identifier, obtain the document identification sequence under the query status identifier as a third document identification sequence based on the query condition;

In some embodiments, when the judgment result characterizes that the snapshot storage module does not include the document identification sequence corresponding to the query status identifier, the characterization cannot obtain the document identification sequence from the snapshot storage module. Therefore, in this embodiment, when the judgment result indicates that the snapshot storage module does not include the document identification sequence corresponding to the query status identifier, the data corresponding to the paging query request can be directly searched from the data storage module, and the query will be based on the analysis. Request the data obtained from the data storage module to be fed back to the user terminal.

In some embodiments, when the judgment result characterizes that the snapshot storage module does not include the document identification sequence corresponding to the query state identifier, the characterization snapshot storage module does not include the query state identifier or does not include the document identifier corresponding to the query state identifier. sequence. Therefore, in this embodiment, when the judgment result indicates that the snapshot storage module does not include the document identification sequence corresponding to the query status identification, the document identification sequence can be obtained based on the query condition, and the obtained document identification sequence can be used as the third document identification. Sequence, it is understandable that the third document identification sequence corresponds to the query status identifier corresponding to the query condition, and further, the third document identification sequence may also correspond to the query status identifier corresponding to the query condition and the user identifier.

Step S360: Write the third document identification sequence into the snapshot storage module.
