Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a data download method, apparatus, electronic device, and storage medium. Background Technology

[0002] In bank data analytics platforms and interactive reporting systems, users often need to explore data details through multi-level drill-down operations. For example, they might need to obtain active user statistics from head office to branches, sub-branches, and outlets. These scenarios place higher demands on the data export functionality. The following requirements must be met: users should be able to export all expanded levels of data identical to what is displayed on the page (including dynamically loaded paginated data); duplicate requests or data processing delays should be avoided to prevent excessive user wait times or page crashes; historical operation data should be exportable even in offline environments; and server load and front-end storage usage should be reduced in high-concurrency scenarios. However, existing data export solutions are not only slow to download data and unable to guarantee data consistency, but also cause rapid memory expansion and insufficient storage space during data download; limited cache capacity leads to low system stability; and reliance on memory or page lifecycle means that cache is lost when the page is refreshed, resulting in poor data persistence. Summary of the Invention

[0003] This invention provides a data download method, apparatus, electronic device, and storage medium to solve the problems of unstable data download, resulting in cache loss after page refresh and poor data persistence.

[0006] In response to the download request, the download request is parsed to obtain the first download information; the first download information includes the download information range, the second component identifier, and the download request type; the second component identifier is the identifier of the component that can analyze and organize the resource change information generated by the first component, and can also provide operation services that the first component does not have;

[0007] The download file is determined based on the first download information and the first data link; the download file is a file generated from the operation record indicated by the download request.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] Figure 1 This is a flowchart illustrating a data download method provided in an embodiment of the present invention. This embodiment is applicable to downloading bank business records. The method can be executed by a data download device, which can be implemented in hardware and / or software and can be configured in any electronic device with network communication capabilities. Figure 1 As shown, the method includes:

[0029] S110. Determine the first data chain; the first data chain is used to record the first data according to the timestamp; the first data is the operation record generated when the resource information of the first component is changed; the first component is used to provide corresponding operation services for the resource information change.

[0030] The first component is a service component that provides modification services for resource information.

[0031] Furthermore, based on the business requirements that have changed according to the resource information, a first component capable of achieving the corresponding function is matched.

[0032] The first data is the operation record obtained by recording each step of the resource change when the resource information is changed through the first component.

[0033] The operation log can include at least: expanded nodes, filter conditions, and page turning.

[0034] The first data chain is a data chain with the second component as the root node, and the operation records of each first component under the second component are sorted according to the timestamp.

[0035] The second component is the parent component of the first component. It is used to analyze and record the operation records generated by the first component and has operation services that the first component does not have.

[0036] Furthermore, the first data link includes two parts: the second data link and the third data link.

[0037] The second data chain, also known as the operation record chain, is used to record the operation corresponding to each resource information change according to the timestamp.

[0038] For example, such as Figure 2 As shown in the figure, the operation record chain records the operation records of the first component under the second component. It can be seen from the figure that the second component contains four operations, which are sorted in chronological order.

[0039] The third data chain, also known as the incremental snapshot chain, is used to record data changes for each resource information according to timestamps.

[0040] For example, such as Figure 3 As shown, the incremental snapshot chain records the differences between the generated version and the previous version after each operation on the same resource information. As can be seen from the figure, the resource information has been modified three times: adding rows, deleting rows, and modifying fields.

[0041] Specifically, the first component is monitored in real time. When an operation is detected in the first component, the operation record of the first component is recorded. A hash value is generated based on the obtained operation record using an encoding algorithm. The hash value is then bound to the operation record to obtain the first data. The identifier of the second component is determined based on the first component. Starting from the second component identifier, the operation record chain is generated by sorting the data according to the timestamps corresponding to the first data. For resource information modified by the operation record, the difference between each modified and unchanged resource information is recorded, i.e., an incremental snapshot. The difference is sorted according to the timestamps corresponding to each modification to obtain an incremental snapshot chain. The obtained incremental snapshot chain and operation record chain are combined and organized to obtain the first data chain.

[0042] Furthermore, after acquiring the first data chain, the first data chain is permanently stored in VUEX and synchronized to IndexedDB to ensure that the data is not lost after refreshing or closing.

[0043] The above steps, where the first data chain only stores the operations and incremental snapshots of each change to resource information instead of the full data, can reduce storage usage by more than 80%.

[0044] S120. Respond to the download request, parse the download request, and obtain the first download information; the first download information includes the download information range, the second component identifier, and the download request type; the second component identifier is the identifier of the component that can analyze and organize the resource change information generated by the first component, and can also provide operation services that the first component does not have.

[0045] Specifically, the Service Worker intercepts download requests and responds to them, determining the type of the download request. The content within the download request is parsed to obtain the download information range and the second component identifier. The obtained download request type, download information range, and second component identifier are then combined to obtain the first download information.

[0046] S130. Determine the download file based on the first download information and the first data link; the download file is a file generated from the operation record indicated by the download request.

[0047] Specifically, if the download type in the first download information is offline download, then the system matches the historical download operation chain database based on the first download information. If an operation chain consistent with the first download information is found, the matched operation chain is used as a pre-download operation chain, and incremental snapshots are applied to the pre-download operation chain in version order starting from the initial version. The browser's Readable Stream and Writable Stream APIs are used to gradually generate the download file. If no operation chain consistent with the first download information is found, the same download method as online download is used. If the download type is online download, after clicking download, the system searches the indexedDB for a consistent operation trajectory list. If found, the list is selected, its incremental snapshot is loaded, and dynamic data merging is performed to generate the download file. If not found, the first data chain is obtained from the backend, the download file is generated based on the first data chain, and the download file is stored in the indexedDB and the historical download operation chain database.

[0048] For example, a comparative experiment was conducted using the above method, local caching, and full recursive requests to compare the generation of download files from the enterprise-level reporting platform. The experimental results are shown in Tables 1 and 2. The enterprise-level reporting platform covers a 5-level drill-down structure, contains 100,000 rows of basic data, and includes dynamic pagination loading.

[0049] Table 1 Comparison of Memory Usage

[0050]

[0051] Table 2 Comparison of Download Time

[0052]

[0053] Furthermore, as can be seen from the table, the method of this application can improve storage efficiency, reduce storage usage by 84%, reduce memory usage by more than 90%, and increase download speed by 300%.

[0054] Optionally, determine the first data link, including steps A1-A4:

[0055] Step A1: Determine the first data.

[0056] Specifically, the first component is monitored in real time. When a triggered operation is detected in the first component, the operation record of the first component is recorded to obtain the second information. Based on the obtained second information, a hash value is generated using an encoding algorithm. The obtained hash value is bound with the second information to obtain the first data.

[0057] The second piece of information includes at least: the object operation type, the timestamp of each operation, and the operation parameters for each operation. The operation parameters can be one of the following: the first component identifier, the pagination page number, or the filter criteria. The object operation type can be: drilldown.

[0058] The encoding algorithm can be the SHA-256 algorithm. The SHA-256 algorithm is used to convert second information of arbitrary length into a fixed-length hash value, possessing characteristics such as irreversibility and collision resistance. The fixed length is 256 bits, or 32 bytes.

[0059] Step A2: Determine the second data chain based on the first data and the first component; the second data chain is used to describe the operation records generated by the first component under the same second component when making changes to resource information.

[0060] The second data chain consists of operation records generated by all first components under the same second component when modifying resource information, and is sorted according to the timestamps corresponding to the operation records. The second data chain is used to represent the dependencies and execution order between various operations.

[0061] Specifically, the identifier of the second component is obtained based on the first component, and the first data is sorted according to the timestamp of the first data using the second component identifier as the root node to obtain the second data chain.

[0062] Furthermore, after acquiring the second data chain, it is permanently stored in VUEX and synchronized to IndexedDB to ensure that the data is not lost after refreshing or closing.

[0063] For example, such as Figure 2 As shown, under the second component, there are four operation records, which are sorted in chronological order.

[0064] The above steps preserve the dependencies and execution order between operations during the construction of the second data chain, ensuring that the complete business process can be restored during offline playback.

[0065] Step A3: Determine the third data chain based on the first data and the first information; the first information is the change information generated after the first change operation modifies the resource information; the third data chain is used to record the change operations of the same data information under different timestamps; the first change operation is the change operation before the timestamp corresponding to the second change operation, and is the same as the data information changed by the second change operation; the second change operation is the change operation corresponding to the first data.

[0066] The first piece of information can also be referred to as an incremental snapshot.

[0067] Specifically, based on the timestamp corresponding to the first data, the changes in resource information after modifications were made before that timestamp are identified and used as the first information. The third information corresponding to the first data is then compared with the resource information of the previous version using the Myers difference algorithm. Based on the comparison results, difference information is generated. The obtained difference information and the first information are then sorted by timestamp to obtain the second data chain.

[0068] Among them, the resource information of the previous version is the resource information corresponding to the timestamp with the smallest difference between the timestamp corresponding to the first information and the timestamp corresponding to the first data.

[0069] Furthermore, after acquiring the third data chain, the information is stored in IndexedDB in the order of resource information version number, forming a singly linked list structure.

[0070] For example, such as Figure 3 As shown, the change record chain records the differences between the generated version and the previous version after each operation on the same resource information. As can be seen from the figure, the resource information has undergone three changes: adding a row, deleting a row, and changing a field.

[0071] The above steps enable the construction of the third data chain to support rapid backtracking to any historical version.

[0072] Step A4: Generate the first data chain based on the first data chain and the second data chain.

[0073] Specifically, the first data chain and the second data chain are stored according to their timestamps to obtain the first data chain.

[0074] Optionally, determine the first data, including steps B1-B3:

[0075] Step B1: Bind the preset function to the operation identifier configured in the first component, and monitor the triggering of the operation identifier in real time.

[0076] Specifically, the operation services that the first component needs to complete are determined, and the preset functions required to complete these services are identified based on these services. These preset functions are then bound to operation identifiers configured within the first component. After binding, the triggering status of the operation identifiers is monitored in real time.

[0077] For example, a preset function `v-track-drilldown` is registered, and a drill-down button or trigger element is bound to the operation identifier of the first component. The triggering status of the operation identifier of the first component is monitored in real time by listening to the click event of the element.

[0078] Step B2: Obtain the operation record of the first component based on the triggering situation to obtain the second information.

[0079] Specifically, if the trigger condition is triggered, the operation record of the first component of the first component is recorded according to the timestamp to obtain the second information; if the trigger condition is not triggered, monitoring continues.

[0080] The second piece of information includes at least: the object operation type, the timestamp of each operation, and the operation parameters of each operation.

[0081] Step B3: Generate a first identifier based on the second information, and bind the second information and the first identifier to obtain the first data; the first identifier uniquely represents the second information.

[0082] Specifically, a hash value is generated based on the second information using the SHA-256 algorithm, and this hash value is used as the first identifier. The second information is then bound to the first identifier to obtain the first data.

[0083] For example, first, the global directive `v-track-drilldown` is registered, binding a drill-down operation button or trigger element to the operation identifier of the first component. By monitoring the element's click event, the object's operation type, timestamp, and operation parameters are captured. The acquired object operation type, timestamp, and operation parameters are used as second information. The SHA-256 algorithm is used to generate a data hash value from the second information. The hash value is then bound to the current operation record to form the first data.

[0084] Optionally, the second data chain is determined based on the first data and the first component, including steps C1-C2:

[0085] Step C1: Determine the identifier of the second component based on the first component.

[0086] Specifically, the second component is determined based on the subordinate relationship of the first component. The identifier of the second component is then obtained based on the second component.

[0087] The subordinate relationship is used to record the relationship between the second component and the first component.

[0088] Step C2: Sort the first data according to the timestamp of the first data and bind it with the second component identifier to obtain the second data chain.

[0089] Specifically, the second data chain is obtained by sorting the first data according to the timestamp of the first data, with the second component identifier as the root node.

[0090] Optionally, a third data chain is determined based on the first data and the first information, including steps D1-D3:

[0091] Step D1: Determine the third information based on the first data.

[0092] Specifically, the modified resource information is determined based on the first data and used as the third information.

[0093] Step D2: Determine the fourth information based on the third information.

[0094] Specifically, the Myers difference algorithm is used to compare the third information corresponding to the first data with the resource information of the previous version. Based on the comparison results, difference information is generated and the obtained difference information is used as the fourth information.

[0095] Among them, the resource information of the previous version is the resource information corresponding to the timestamp with the smallest difference between the timestamp corresponding to the first information and the timestamp corresponding to the first data.

[0096] Step D3: Generate the third data link based on the fourth information and the first information.

[0097] Specifically, the fourth information is integrated with the first information in ascending order of timestamps to obtain the third data chain.

[0098] Optionally, the download file is determined based on the first download information and the first data link, including steps E1-E3:

[0099] Step E1: Determine the download type based on the first download information; the download type is used to indicate whether the download request is an online download.

[0100] Specifically, the download type corresponding to the download request is obtained from the first download information.

[0101] Step E2: If the download type is offline download, then generate the download file based on the first download information and the first data link.

[0102] Specifically, if the download type is offline download, the system matches the historical download operation chain database based on the first download information. If an operation chain matching the first download information is found, it is used as a pre-download operation chain. Incremental snapshots are applied to the pre-download operation chain starting from the initial version and in version order, and the download files are generated step by step using the browser's Readable Stream and Writable Stream APIs. If no operation chain matching the first download information is found, the same download method as online download is used.

[0103] Furthermore, download files are generated through block-based writing. This involves splitting the pre-download operation chain into multiple blocks and processing them one by one. Then, a streaming conversion writing method is used to convert each data block to the target format, and the converted data is written to disk in blocks, thus freeing up memory. The Service Worker generates download files for each data block in the target format it acquires. Finally, memory usage is monitored in real time, and if it approaches browser limits, it automatically switches to a compression algorithm with lower memory consumption.

[0104] Furthermore, during the process of generating the download file, the hash value contained in the first download information is compared with the hash value corresponding to each record node in the pre-download operation chain. If the match fails, an alarm is triggered, and a prompt is made to indicate whether to continue exporting or to stop downloading.

[0105] Furthermore, the process of generating download files also includes: if the length of the pre-download operation chain is greater than the length required for the first download information, the target operation chain can be quickly located, and only the snapshot corresponding to that version can be merged.

[0106] Step E3: If the download type is online download, retrieve the corresponding data information from the first data link based on the first download information and generate the download file.

[0107] Specifically, if the download type is online download, after clicking download, the system searches the indexedDB for a matching operation trace list. If found, the list is selected, its incremental snapshot is loaded, and dynamic data merging is performed to generate the download file. If not found, the system retrieves the first data chain from the backend, generates the download content based on the first data chain, and stores the download content in the indexedDB.

[0108] The above steps utilize a replay-based approach to generate downloaded files, eliminating the need for repeated server requests and increasing download speed by more than three times. Furthermore, versioned storage and offline support allow for the export of historical version data in offline environments.

[0109] Optionally, a download file is generated based on the first download information and the first data link, including steps F1-F3:

[0110] Step F1: Match the data link from the historical database based on the first download information.

[0111] Specifically, based on the download information range in the first download information, the database is matched to see if a data chain with the corresponding range exists.

[0112] Step F2: If a matching data chain exists, generate a download file from the matched data chain.

[0113] Specifically, if a corresponding data chain exists, the matched operation chain is used as the pre-download operation chain. Incremental snapshots are applied to the pre-download operation chain starting from the initial version and in version order. Download files are generated step by step using the browser's ReadableStream and WritableStream APIs. During the generation of download files, the hash value contained in the first download information is compared with the hash value corresponding to each record node in the pre-download operation chain. If a match fails, an alarm is triggered, prompting whether to continue exporting or abort the download.

[0114] Step F3: If no matching data chain exists, the first data chain is filtered according to the first download information, and a download file is generated.

[0115] Specifically, if no matching data chain exists, after clicking download, the system searches the indexedDB for a consistent operation trajectory list. If found, the list is selected, its incremental snapshot is loaded, and dynamic data merging is performed to generate the download file. If not, the first data chain is retrieved from the backend, the download content is generated based on the first data chain, and the download content is stored in the indexedDB.

[0116] For example, such as Figure 4 As shown, when a download request is detected, the client registers a Service Worker to intercept the download request and monitor the download request initiated by the front end. If an offline state is detected, a data chain consistent with the current download operation is matched from the historical operation chain database. If a consistent data chain exists, IndexedDB returns the operation chain. The Service Worker loads the incremental snapshot in the data chain, merges the differences in the operation chain, and sends it to the differential merger. The differential merger paginates the data chain passed by the Service Worker, splits it into multiple blocks, and sends the data blocks to the streaming writer. The streaming converter converts each data block into the target format and generates the download file.

[0117] The technical solution of this embodiment determines a first data chain. Generating the first data chain reduces storage usage while accelerating the generation of downloaded files, thereby improving download speed. Responding to a download request, the method parses the download request to obtain first download information. Based on the first download information and the first data chain, the method determines the download file, ensuring the stability of the downloaded file and preventing data loss during the download process. This method generates the first data chain by recording the operation records and changes in the resource information. Download files are generated based on different download types in the download request and the first data chain. This eliminates the need for repeated requests to the server, improving download speed. Furthermore, the provision of different download methods meets diverse download needs and adapts to different network environments.
