[0033] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0034] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0035] The data reading method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the server 104 via the network.

[0036] For example, the data reading method is applied to the terminal 102. After receiving the data reading instruction, the terminal 102 can determine the target database corresponding to the data reading instruction from the data storage system of the server 104, and extract the target data from it and store it in the buffer; further, the terminal 102 can slice the target data in the buffer based on the pre-set paging base, and send the sliced ​​target data to the receiving object corresponding to the data reading instruction in sequence. Among them, the terminal 102 can be but not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers. The terminal 102 and the server 104 can be directly or indirectly connected by wired or wireless communication, such as through a network connection.

[0037] For another example, the data reading method is applied to the server 104. After receiving the data reading instruction, the terminal 102 can send the data reading instruction to the server 104. The server 104 can determine the target database corresponding to the data reading instruction from the data storage system, and extract the target data from it and store it in the buffer; further, the server 104 can fragment the target data in the buffer based on the pre-set paging base, and send the fragmented target data to the receiving object corresponding to the data reading instruction in sequence. It can be understood that the data storage system can be an independent storage device, or the data storage system is located on the server 104, or the data storage system is located on another terminal.

[0038] In one embodiment, a data reading method is provided. This embodiment uses the data reading method applied to a terminal as an example for illustration. It is understandable that the data reading method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. Figure 2 As shown, the data reading method includes:

[0039] Step 202 : In response to a data read instruction, extract target data from a target database corresponding to the data read instruction and store the target data in a buffer.

[0040] The data read instruction refers to an instruction for obtaining data stored in a specific database.

[0041] Among them, the data reading instruction can be issued by the user through the human-computer interaction interface of the terminal. The human-computer interaction interface of the terminal can specifically display the platform interface pre-specified by the service provider. The staff issues the data reading instruction by clicking on a specific component on the specified platform interface. It should be noted that the user can also issue data reading instructions for different databases by clicking on pre-integrated components for indicating different databases on the specified platform interface.

[0042] The target data refers to data that another terminal or another server that issues the data read instruction wants to read from the data storage system of the server.

[0043] A buffer refers to a driver cache in a data storage system that is used to temporarily store target data. It is usually used to provide a smooth data flow between a terminal or server and another terminal or server that issues the data read instruction. In particular, when the processing speed of the terminal or server does not match that of the other terminal or server that issues the data read instruction, the buffer can help reduce the risk of data loss, improve the efficiency of data processing, and optimize the use of system resources.

[0044] Step 204 : segment the target data in the buffer based on a preset paging base, and send the segmented target data to the receiving objects corresponding to the data read instructions in sequence.

[0045] The paging cardinality is a preset value. During the data segmentation process, the paging cardinality determines the amount of target data sent to the receiving object, ie, the terminal, each time.

[0046] As an example, the terminal can use the memory resources of the space to create a buffer in advance in the data storage system of the server. When the data read instruction is issued for a data set (dataset) of an application, the terminal extracts the target data of the target database from the data storage system according to the data read instruction of the dataset into the buffer, and then slices the target data in the buffer, and sends the sliced ​​target data to the dataset to complete the data reading. As an example, a dataset is a collection of data, usually in the form of a table, each column represents a specific variable or attribute, and each row corresponds to the data of a member or record in the dataset. The target database is, for example, a query table, and multiple data are stored in the query table.

[0047] It should be noted that the buffer can be implemented in the form of a sliding window.

[0048] The above data reading method, by setting a buffer and using the buffer as an intermediate storage layer, can not only reduce the frequent access of the receiving object to the database, but also help to smooth the data flow, ensure that the target data can be transmitted to the receiving object on demand and in an orderly manner, and avoid performance bottlenecks caused by the mismatch between the processing speed of the terminal or server corresponding to the database and the receiving object. Users can also dynamically adjust the size of the paging base according to the network conditions, thereby realizing customized control of the data transmission speed; and by setting the paging base, the target data with a large data volume can be divided into data slices with a smaller data volume, which can make the amount of data processed each time more controllable. This helps to reduce memory usage, reduce processing time, and improve the throughput of data processing. In addition, the target data after slicing can be processed in parallel as independent data units, which helps to improve the concurrent processing capability of the system and shorten the response time of data processing.

[0049] In some optional embodiments, before extracting the target data from the target database corresponding to the data reading instruction and storing it in the buffer, the method further includes:

[0050] Obtaining the target data volume corresponding to the data reading instruction;

[0051] The step of extracting target data from a target database corresponding to a data read instruction and storing the target data in a buffer includes:

[0052] When the target data volume reaches the paging base, the target data is determined from the target database according to the target data volume, and the target data of a first preset data volume is extracted and stored in the buffer; the first preset data volume is determined based on the maximum storage capacity of the buffer.

[0053] The target data volume corresponding to the data read instruction refers to the total amount or size of data that the receiving object intends to retrieve or read from the target database. This data volume can be measured in the form of number of records, number of bytes, number of data blocks, etc.

[0054] The maximum storage capacity of the buffer refers to the maximum amount of data that the buffer can store, that is, the first preset data amount. The first preset data amount can be measured based on bytes, the number of records, the number of data blocks, etc. Once the amount of data stored in the buffer reaches the first preset data amount, some measures need to be taken, such as suspending data writing, sending data to the receiving object, etc., to avoid data overflow.

[0055] In another embodiment, the data reading method further includes:

[0056] When the target data volume does not reach the paging base, the target data volume of target data is extracted from the target database and sent to the receiving object.

[0057] Using a buffer requires additional memory resources to store the target data. When the target data volume corresponding to the data read instruction is less than the paging base, it means that the target data volume is small, and the cost of using additional memory resources to buffer and flatten the target data may not be cost-effective. Therefore, the terminal can send the target data directly to the receiving object.

[0058] In this embodiment, when the target data volume corresponding to the data reading instruction is less than the paging base, the terminal can directly send the target data to the receiving object, thereby reducing the waiting time of the target data in the buffer, speeding up the data transmission speed, reducing the data processing steps, and reducing the complexity of the system, thereby making the data reading method in this embodiment easier to implement and maintain. When the target data volume corresponding to the data reading instruction is greater than the paging base, the use of the buffer to store the target data is triggered to transmit the target data to the receiving object on demand and in an orderly manner.

[0059] In some optional embodiments, after step 204, the following further steps are included:

[0060] When the amount of target data extracted from the target database does not reach the target data amount, the target data is continuously extracted from the target database and stored in the buffer based on the free storage space of the buffer until all the target data in the target database is stored in the buffer.

[0061] As an example, when the first preset data volume of the buffer is 200kb and the target data volume corresponding to the data reading instruction is 500kb, the terminal stores 200kb of target data that meets the first preset data volume into the buffer in step 202. As the terminal sends the 200kb target data in the buffer to the receiving object in sequence, free storage space will appear in the buffer. At this time, the terminal determines that the data volume of the target data stored in the buffer, 200kb, does not reach the target data volume of 500kb, and continues to extract the target data and store it in the buffer until the data volume of the target data stored in the buffer reaches the target data volume of 500kb.

[0062] Furthermore, the data reading method includes:

[0063] When the amount of data that can be stored in the free storage space reaches a second preset amount of data, target data of the second preset amount of data is extracted from the target database and stored in the free storage space of the buffer.

[0064] In this embodiment, the terminal can monitor the size of the free storage space in the buffer. When the amount of data that can be stored in the free storage space reaches a second preset data amount, it triggers the target data in the target database to be stored in the buffer, thereby avoiding frequent interactions with the target database and avoiding waste of resources.

[0065] In another embodiment, after sharding the target data stored in the buffer, the terminal can also perform concurrent processing on the sharded target data. At this time, it is necessary to determine the number of shards. At this time, the actual amount of target data in the buffer can be divided by the paging base and rounded up to obtain the number of shards.

[0066] Through the above processing, the target data stored in the buffer can be segmented at one time, so that the data segments can be processed in parallel as independent data units, which helps to improve the concurrent processing capability of the system and shorten the response time of data processing.

[0067] In a more specific embodiment, a data storage system on the service provider side corresponding to a specific application can store multiple table data, and the maximum storage capacity of the buffer indicates that the buffer can store 200 table data, and the paging base corresponds to 50 table data. The user sends a data read instruction to the terminal on the service provider side corresponding to the application through the terminal carried by the application. The data read instruction can be used to extract 500 table data from the target database of the data storage system. After receiving the data read instruction, the terminal on the service provider side can use the 500 table data in the target database of the data storage system as the target data. At this time, the terminal can determine that the target data volume 500 of the data read instruction reaches the paging base 50, and then it can trigger the call buffer to store the 200 table data in the buffer first. Further, according to the paging base, the 200 table data in the buffer are fragmented, and the generated fragmented data corresponds to 50 table data, and the fragmented target data is sent to the terminal carried by the application.

[0068] Alternatively, when the maximum storage capacity of the buffer indicates that the buffer can store 200 pieces of table data, the paging base corresponds to 50 pieces of table data, and the data reading instruction is used to extract 10 pieces of table data from the target database of the data storage system, the terminal can determine that the target data volume 10 of the data reading instruction does not reach the paging base 50, and directly send the 10 pieces of table data in the target database as target data to the terminal equipped with the application.

[0069] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
