Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The terms "first," "second," and the like, in this application, are used for distinguishing between similar items and items that have substantially the same function or similar functionality, and it should be understood that "first," "second," and "nth" do not have any logical or temporal dependency, nor do they define a quantity or order of execution. It will be further understood that, although the following description uses the terms first, second, etc. to describe various elements, these elements should not be limited by these terms.

These terms are only used to distinguish one element from another. For example, a first element can be termed a second element, and, similarly, a second element can also be termed a first element, without departing from the scope of various examples. The first element and the second element may both be elements, and in some cases, may be separate and distinct elements.

For example, at least one element may be an integer number of elements equal to or greater than one, such as one element, two elements, three elements, and the like. At least two means two or more, for example, at least two elements may be any integer number of two or more than two, such as two elements, three elements, etc.

Fig. 1 is a schematic diagram of a service system of a target service provided in an embodiment of the present application, where the target service is any kind of service, for example, the target service is a service related to medical detection or other services, and the embodiment of the present application specifically defines the target service.

Referring to fig. 1, the service system includes a terminal 101, a first server 102 and a second server 103, wherein the terminal 101 is connected to the first server 102 through a wired network or a wireless network, the first server 102 is directly or indirectly connected to the second server 103 through a wired network or a wireless network, and in other embodiments, the terminal 101 is further connected to the second server 103 through a wired network or a wireless network.

The terminal 101 in the service system is at least one, and the terminal 101 includes at least one of a smart phone, a tablet computer, a smart speaker, a smart watch, a notebook computer, a smart phone, a smart car device, a portable game device, or a desktop computer, where the type of the terminal 101 in the service system is not limited in this embodiment.

A target application for providing a service related to a target service is installed and executed in the terminal 101. Taking the target service as the service related to medical detection as an example, the service provided by the target application program includes a service data query service, a service data upload service, a user information entry service, and the like of the target service.

Each of the first server 102 and the second server 103 includes at least one of a server, a plurality of servers, a cloud computing platform, or a virtualization center. Optionally, each of the first server 102 and the second server 103 is an independent physical server, or a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, content Delivery Network (CDN), big data and artificial intelligence platform, and the like.

The first server 102 is a main server of the target service, and may also be understood as a main server of the target application program or a main server of the service system. The first server 102 is configured to provide a background service for the target application, for example, the first server 102 provides the background service for the target application by running a background main program of the target application, and the services that can be provided by the target application all depend on the background main program, which is understood to be a main program of the target service.

The background main program occupies hardware resources and network transmission resources of the first server 102 during the running process, wherein the hardware resources include Central Processing Units (CPU) resources, input/output (I/O) resources, and memory resources.

Considering that in the related art, the service data query service provided by the target application program is generally implemented by the main server of the target service, when a large number of terminals query the service data through the main server or query the service data by the terminals in large quantities, the service data query service may occupy a large amount of hardware resources of the main service, which results in a reduction of hardware resources of the main process (or background main program) allocated to the target service by the main server, and further results in a reduction of performance of the main process of the service

Based on this, in the embodiment of the present application, the second server 103 is additionally disposed in the service system, the second server 103 is configured to provide a service data query service for the first server 102, and when the first server 102 has a requirement for querying the service data, the second server 103 can replace the first server 102 to query the service data, so as to save hardware resources required by the first server 102 when querying the service data, and further enable the first server 102 to allocate more hardware resources to the background main program of the target application program, so as to improve performance of the main program of the target service.

Next, based on the service system described above, the following description is made on the query process of the service data in the service system and the query process of the second server replacing the first server for the service data.

Fig. 2 is a flowchart of a data query method provided in an embodiment of the present application, and referring to fig. 2, the embodiment includes the following steps:

201. the terminal sends a service data query request for the target service to the first server, wherein the service data query request indicates to query the service data of the target service.

The first server is a main service of the target service, and the terminal is any terminal provided with the target program. The target service is any kind of service, for example, the target service is a service related to medical detection or other services, and the target service is not specifically limited in the embodiments of the present application. In the case where the target service is a service related to medical examination, the service data of the target service is medical examination data.

The business data query request comprises query conditions of the business data to be queried and information of a query party, wherein the query conditions comprise at least one of acquisition time, acquisition area information, acquisition object information and business types of the business data to be queried. The acquisition region information indicates a region where the service data to be queried is acquired, and the acquisition object information indicates an object (i.e., an acquisition object) to which the service data to be queried belongs, for example, medical detection data obtained by a certain user performing medical detection is service data, and the user is the acquisition object to which the service data belongs. The acquisition object information is information related to an acquisition object of the service data to be queried, such as an identity, a contact way, an address and the like of the acquisition object. The target service comprises at least one sub-service, the service types of different sub-services are different, the service type of the service data to be queried is the service type of the sub-service to which the service data to be queried belongs, the service data to be queried may belong to one sub-service or may attribute multiple sub-services, and here, the number and the type of the sub-services in the target service are not limited in the embodiment of the application, and the sub-service to which the service data to be queried belongs is not limited in the embodiment of the application.

The inquiring party information includes terminal information of the terminal and an account number of the terminal for logging in a target application program, wherein the terminal information includes an identifier of the terminal and/or a network protocol address of the terminal.

The service data query request is generated based on a target application program, illustratively, the terminal displays a query interface of the target service in the process of running the target application program, a user inputs a query condition in the query interface, the user performs query operation on the query condition on the query interface, the terminal responds to the query operation to generate the service data query request, and sends the service data query request to the second server to request the second server to query service data meeting the query condition.

202. The first server determines the quantity of the target service data required by the terminal based on the service data query request of the terminal to the target service.

The target service data required by the terminal is data to be inquired of a service data inquiry request, at least one piece of target service data is provided, and the number of the target service data is the total number of the target service data in the service data of the target service.

In a possible implementation manner, the first server is associated with a first database of the target service, the first database is used for storing service data of the target service, and the first server queries the target service data in the first database based on the service data query request. For example, the first database records metadata of a plurality of pieces of service data of a target service, wherein the metadata of each piece of service data includes at least one of collection time, collection area information, collection object information, and a service type of the service data. After receiving the service data query request, the first server obtains a query condition from the service data query request, queries target metadata meeting the query condition from metadata of a plurality of pieces of service data of a target service, and takes the service data corresponding to each queried target metadata as target service data, namely the target service data meets the query condition.

After the target service data are inquired, the first server counts the number of the inquired target service data, and if the number of the inquired target service data is smaller than the target number, the first server acquires the inquired target service data from the first database and sends the acquired target service data to the terminal. The target number is, for example, 5000 or 10000, and the target number may be set according to a specific implementation scenario, performance of the first server, or performance of the first database, where the target number is not limited in this embodiment of the application.

In another possible implementation manner, after acquiring the target service data from the first database, the first server does not send the target service data to the terminal for the moment, but sends the target service data to the terminal after receiving a download request of the terminal for the target service data. For example, in the process of processing the service data query request, the first server also synchronizes the query progress of the target service data to the terminal, the terminal displays the query progress of the target service data, when the query of the target service data is completed (that is, the first server obtains the target service data meeting the query condition), the terminal displays the query progress of the target service data as the query completion, the user performs a download operation on the queried target service data in a query interface of the terminal, the terminal sends a download request for the target service data to the first server in response to the download operation, and after receiving the download request, the first server sends the queried target service data to the terminal according to the download request.

In a possible implementation manner, the first server imports the queried target service data into a table before sending the target service data to the terminal, packages the table including the target service data into a target file based on the information of the querying party in the service data query request, and sends the target file to the terminal. The target file may be a compressed file or an uncompressed file, and the file name of the target file is obtained based on the information of the querying party, for example, the file name includes the information of the querying party.

Based on the possible implementation manner, under the condition that the number of the inquired target service data is smaller than the target number, the inquired target service data is returned to the terminal by the first server, that is, the first server completely processes the service data inquiry request, and because the number of the target service data is smaller than the target number, even if the first server completely processes the service data inquiry request, the hardware resource of the first server is not greatly occupied in the process of processing the service data inquiry request, so that the influence of the service data inquiry request on the performance of the main flow of the target service is small at this time.

203. And if the quantity of the target service data is larger than or equal to the target quantity, the first server submits a target query task to the second server of the target service based on the service data query request, and the target query task indicates that the service data query request is completed.

The target query task comprises query conditions of the target business data and information of a query party.

If the number of the target service data is larger than or equal to the target number, the first server generates a target query task based on the query condition and the information of the query party in the service data query request, submits the target query task to the second server, and the second server completes the service data query request based on the target query task.

The first server submits the target query task to the second server in any one of the following modes A1 or A2.

In the method A1, if the number of the target service data is greater than or equal to the target number, the first server sends the target query task to the second server.

In the method A2, if the number of the target service data is greater than or equal to the target number, the first server records the target query task in the task table of the target service, and the task table is visible to the second server.

The task table is used for recording query tasks generated by the first server based on the service data query requests of the terminals. In addition, the state table is also used for recording the task state of each query task, so that the first server and the second server can learn the task state of each query task from the state table at any time. For example, when the first server records the target query task in the state table, the first server also records the task state of the target query task as unexecuted to instruct the second server to execute the target query task.

In a possible implementation manner, the task table is stored in a first database associated with the first server, and the second server has a data query right for the first database. For example, if the number of the queried target service data is greater than or equal to the target number, the first server records the target query task in the task table in the first database, and since the second server has a data query right for the first database, the second server can query the state table in the first database, so that the first server records the target query task in the task table in the first database, and can submit the target query task to the second server.

In another possible implementation manner, the second server does not have the data query authority for the first database, the second server is associated with the second database of the target service, and the second server has the data query authority for the second database. The second database is used for storing a copy of the service data of the target service in the first database, and the second database is also used for storing a copy of the task table in the first database, it can be understood that the second database is a copy database in the first database to serve as a hidden node of the first database, and the second database and the first database store data (such as service data or status table) and store data in the same manner.

For example, the first database has a function of synchronously storing data to the second database, if the number of the queried target service data is greater than or equal to the target number, the first server records the target query task in the task table in the first database, and then the second database synchronizes the target query task recorded newly in the task table to the task table in the second database.

204. The second server obtains the target query task submitted by the first server.

And if the first server submits the target query task to the first server in a sending mode, the second server receives the target query task sent by the first server to obtain the target query task submitted by the first server.

And if the first server submits the target query task to the first server in the task table, the second server scans all query tasks recorded by the first server in the task table to obtain query tasks which are not executed yet, and the query tasks which are not executed yet are used as the target query tasks. For example, the second server periodically scans the task state of each query task in the task table, and if the task state scanned to any query task is not executed, the query task is taken as the target query task. In addition, after scanning the target query task, the second server may further update the task status of the target query task to be in execution to indicate that the second server is executing the target query task, where the process of the second server executing the target query task includes the following steps 205 and 206.

205. And the second server inquires the target business data in the business data of the target business based on the target inquiry task.

And after the second server acquires the target query task, querying the target service data meeting the query condition in the service data of the target service according to the query condition in the target query task.

For example, the second server has data query authority for a first database associated with the first server, the second server queries the target business data in the first database based on the query condition, and the query process may refer to a process in which the first server queries the target business data in the first database based on the query condition.

For another example, the second server does not have the data query right on the first database associated with the first server, and the second server is associated with a second database of the target service, where the second database is used to store a copy of the service data of the target service in the first database, it can be understood that the second database is a copy database in the first database, and serves as a hidden node of the first database, and the service data and the stored service data stored in the second database and the first database are the same.

The second server has data query authority to the second database, and the second server queries target service data in the second database based on the target query task. Illustratively, the second server queries the target business data in the first database based on the query condition in the target query task, and the query process may refer to a process in which the first server queries the target business data in the first database based on the query condition.

When the second server queries the target service data from the second database, the target service data is acquired from the second database, and in the process that the second server acquires the target service data from the second database, the transmission bandwidth of the second database and the link in the second database are occupied, but the target service data is not acquired from the first database, so that the transmission bandwidth and the link occupied by the first database can be reduced, the first database can provide sufficient transmission bandwidth and more links for the main process of the target service in the first server, and the performance of the main process of the target service and the service performance of the first server can be further improved.

206. And the second server provides the inquired target service data to the first server.

The second server may provide the target service data for the first server in the following manner B1 or B2.

In the mode B1, the second server sends a task completion response of the target query task to the first server, and the task completion response carries the queried target service data.

For example, the second server imports a plurality of pieces of target service data which are inquired into a form, packages the form including the plurality of pieces of target service data into a target file based on inquirer information in a target inquiry task, generates a task completion response based on the target file, and sends the task completion response to the first server. Wherein the task completion response includes the target file.

In the method B2, the second server stores the queried target service data to the shared disk between the first server and the second server, and the first server reads the target service data from the shared disk.

And the first server and the second server have the authority of writing data, reading data, deleting data and modifying data on the shared disk. The shared disk may be a cloud disk, rather than a disk local to the first server or the second server, and even if the first server and the second server are restarted, the target service data stored in the shared disk is not lost.

For example, after the second server packages the queried target service data into a target file, the target file is stored in the shared disk, so as to complete the provision of the target service data to the first server.

In addition, after the second server provides the target service data to the first server, the task state of the target query task in the task table can be updated from execution to execution completion so as to indicate that the target query task is executed and completed. For example, in the case that the first database is not associated with the second database, the first server updates the task state of the target query task in the task table in the first database to completion of execution, so that the first server queries the current task state of the target query task. For another example, when the second database is associated with the first database, the first server updates the task state of the target query task in the task table in the first database to completion of execution, and the second database synchronizes the updated task state (i.e., completion of execution) of the target query task to the state table in the first database, so that the first server queries the current task state of the target query task.

207. And the first server acquires the target service data inquired in the service data of the target service by the second server based on the target inquiry task.

For example, the first server receives a task completion response of the target query task sent by the second server, and acquires the target service data from the task completion response.

For another example, the first server queries the task state of the target query task in the state table, and when the task state of the target query task is found to be execution completion (that is, the second server completes the target query task), the first server reads the target service data from the shared disk between the first server and the second server.

The process of reading the target data from the shared disk by the first server may be: the first server inquires a file name comprising the inquirer information in the file names of the files stored in the shared disk according to the inquirer information in the business data inquiry request indicated by the target inquiry task, and if the file name of any file includes the inquirer information, the any file is a target file comprising target data.

208. And the first server sends the target service data to the terminal.

For example, after acquiring the target file including the target service data by executing step 207, the first server sends the target file to the terminal.

It should be understood that the processes shown in the above steps 201-208 are processes in which the terminal requests the first server to export the target file, in the case that the terminal has a need to export the target file, the first server is requested to package the queried data into the target file by sending a service data query request to the first server, if the number of target service data queried by the first server based on the service data query request is not too large (e.g. the number is smaller than the target number), the first server packages the queried target service data into the target file, otherwise, the first server submits the query task of the service data query request (i.e. the target query task) to the second server, and the second server queries the target service data, packages the queried target service data into the target file, and provides the target file to the first server. Under the condition that a terminal-based service data query request is configured and queried service data can be directly returned, the first server returns the target file to the terminal after acquiring a self-packaged target file or a target file provided by the second server, and under the condition that the terminal-based service data query request is not configured and queried service data can be directly returned, the first server waits for a download request (namely a download request for the target file) of the terminal to the queried target service data, and sends the self-packaged target file or the target file provided by the second server to the terminal after receiving the download request.

According to the method provided by the embodiment of the application, after the quantity of the target service data required by the terminal is determined based on the service data query request of the terminal to the target service, if the quantity is larger than or equal to the target quantity, the main server (namely, a first server) of the target service submits the target query task to another server (namely, a second server), and the other server executes the target query task to replace the main server to complete the service data query request, so that asynchronous decoupling processing of the service data query request is realized, the main server is not required to process the service data query request, the occupation of hardware resources of the main server is reduced, the main server can have sufficient hardware resources to provide services for the main process of the target service, and the performance of the main process of the target service can be improved.

In another possible implementation manner, the target service includes multiple sub-services, a part of the sub-services in the multiple sub-services may also be provided with a background service by at least one third server outside the first server and the second server, the shared disk between the second server and the third server can also open an authority for the at least one third server, and then the at least one third server can also write the service data of the sub-service of the local terminal to the shared disk, or read the service data of other sub-services from the shared disk, thereby implementing cross-task file interaction, and a file in the shared disk will not be lost with the restart of a server in the service system or the restart of a local POD (POD) of the server, and the file in the shared disk will be safer. The POD is a minimum management unit of a container cluster management system Kubernetes, and comprises at least one container, and the containers in the POD can share storage resources and network resources.
