Description

Technical Field

[0001] The present application relates to the technical field of storage space management, and in particular to a method and device for managing file storage space in a SAAS platform. Background Art

[0002] With the development of cloud computing technology, SAAS (Software as a Service) platform is also built and developed based on cloud computing technology. In the SAAS platform architecture, in order to meet the needs of system scalability and reliability, a distributed storage system is usually used as a file storage solution, which brings the following problems: 1. The distributed file storage system has low efficiency in calculating the space under the user storage path and takes a lot of time.

[0003] 2. In a distributed platform, the file operation logic is scattered in the services of various business modules. If each business module independently handles the checking and updating of the user's file storage quota, each business module needs to call the above-mentioned calculation logic for calculating the user's storage file space when checking the file storage quota, which is not only inefficient but also causes a waste of computing resources. When updating the user's used storage quota, a synchronization mechanism needs to be adopted, otherwise there is a risk of conflict, which will make the storage space quota control logic invalid.

[0004] 3. The file management system connected to the SAAS platform may adopt a variety of different storage solutions. If each business module is connected separately, each business module needs to adjust the connected storage components.

[0005] Therefore, the current file storage space management method of the SAAS platform makes the real-time update of the file storage space quota poor and the management efficiency low. How to improve the real-time update of the storage space quota and the efficiency of storage space management has become an urgent problem to be solved. Summary of the invention

[0020] See also Figure 1 , Figure 1 It is a schematic flow chart of a method for managing file storage space in a SAAS platform provided in an embodiment of the present application.

[0021] like Figure 1 As shown, the method for managing file storage space in the SAAS platform specifically includes steps S101 to S105.

[0022] S101. Upon receiving a file storage request from a user, calling the file operation interface based on the business module to obtain a remaining storage amount of the file storage space of the user; Furthermore, based on the business module, the file operation interface is called to obtain the remaining storage amount of the user's file storage space, including: based on the business module, the file operation interface is called; based on the file operation interface, the storage capacity quota acquisition interface and the used storage capacity acquisition interface of the user resource management module are called to respectively obtain the storage capacity quota and the used storage capacity of the user's file storage space; based on the storage capacity quota and the used storage capacity, the remaining storage amount is obtained.

[0023] In one embodiment, the method for managing file storage space in the SAAS platform is applied to a file storage space management system, which includes: a user resource management module, a file storage module, a message queue module, and a file operation interface.

[0024] Among them, the user resource management module has functions including setting and managing user file storage space quotas, and provides the following interfaces to the outside world: setting the user's file storage capacity quota, obtaining the user's file storage capacity quota, obtaining the user's used file storage capacity, adjusting the user's used file storage capacity, and recalculating the user's used file storage capacity.

[0025] The file storage module is used to store user files and provides the following interfaces: store files, replace files, delete files, obtain file information, and calculate storage capacity.

[0026] The message queue module is used to send file operation event messages and should provide the following interfaces: create message queues, send messages to topics, and subscribe to message topics.

[0027] The file operation interface is internally connected to the interface of the above-mentioned file storage module, and provides the following file operation interfaces to the business module: store files, update files, delete files, obtain file information, obtain file storage capacity, and obtain file storage quota.

[0028] In one embodiment, the above-mentioned user resource management module is constructed. In the SAAS platform, it is usually in the same module as the user management module, provides a user resource configuration management interface, and stores data in a persistent storage service such as a relational database; the interface of the above-mentioned user resource management module is implemented, which is usually provided as a RestAPI or RPC interface.

[0029] In one embodiment, the file storage module may be constructed using an open source solution or a cloud service, and the interface function provided by the module should meet the above interface requirements.

[0030] In one embodiment, the message queue module may be constructed by adopting an open source message queue solution or using cloud services, and its functions shall meet the message queue interface requirements.

[0031] In one embodiment, the above-mentioned file operation interface is constructed, connected to the external interfaces of the above-mentioned user resource management module and file storage module, and the above-mentioned file operation interface is implemented.

[0032] S102: When the remaining storage amount is greater than or equal to the size of the file to be stored, storing the file to be stored based on the file storage module; S103: Generate a file storage event message based on the file information and storage status of the file to be stored; S104: Based on the message queue module, sending the file storage event message to a message queue corresponding to the file storage; S105: Based on the user resource management module, obtain the file storage event message from the message queue, and based on the file storage event message, update the file storage space quota of the user.

[0033] In one embodiment, SAAS (Software as a Service) is a software distribution model in which software applications are hosted in the cloud and users can access these applications through the Internet without installing and running them on local computers. In a SAAS platform, storage space generally refers to the virtual space provided by the platform to users for storing files, data and other information.

[0034] In one embodiment, the business module is responsible for processing user requests and calling the file operation interface when receiving a file storage request. The file operation interface then calls the storage capacity quota acquisition interface and the used storage capacity acquisition interface of the user resource management module. These two interfaces return the user's storage space quota (such as 10GB) and the current amount of storage space used (such as 5GB) respectively. Through arithmetic operations (storage space quota - used storage capacity), the system calculates the user's current remaining storage quota (such as 10GB - 5GB = 5GB).

[0035] In one embodiment, if the calculated remaining storage amount is greater than or equal to the size of the file to be stored (e.g., 5GB>3GB), the file storage module will start processing the uploaded file to be stored. The file storage module is responsible for actually writing the file into the storage system, which may include pre-processing steps such as file encryption, compression, and segmentation, as well as writing the file data into a physical or virtual storage location.

[0036] In one embodiment, after a file is successfully stored, the system generates a file storage event message based on the stored file information and storage status. The message may include information such as the file name, file size, storage location, storage timestamp, and the status of the storage operation (success or failure).

[0037] In one embodiment, the generated file storage event message will be sent to a specific queue in the message queue module. This queue is used to process events related to file storage, ensuring that all system components that need to know the file storage status can receive this event.

[0038] In one embodiment, the user resource management module monitors messages about file storage in the message queue. When a storage event message is detected, the message is extracted from the queue. Then, the user resource management module updates the user's file storage space quota according to the content of the message, and increases the user's used storage quota by the corresponding file size.

[0039] In a specific embodiment, the business module calls the storage file interface of the above-mentioned file operation interface. The interface checks whether the remaining quota can store the current file by calling the above-mentioned user resource management module to obtain the user's file storage capacity quota and obtain the user's used file storage capacity. If the quota is exceeded, an error message is returned. If the limit has not been reached, the file is stored through the storage file interface of the above-mentioned file storage module, and then a file storage event message is generated and sent to the message queue of the corresponding topic through the publishing message interface of the above-mentioned message queue module.

[0040] In one embodiment, the user resource management module subscribes to the file storage event message in the message queue module, obtains the storage file size, and adds it to the user's used storage space quota.

[0041] See also Figure 2 , Figure 2 It is a schematic flow chart of a method for managing file storage space in a SAAS platform provided in an embodiment of the present application.

[0042] like Figure 2 As shown, the method for managing file storage space in the SAAS platform specifically includes steps S201 to S206.

[0043] S201. Upon receiving a file update request from the user, determining a file to be updated, and based on the business module, calling the file operation interface to obtain an original file corresponding to the file to be updated and file information of the original file; S202: comparing the file sizes of the original file and the file to be updated based on the file information of the original file; S203: When the file size of the file to be updated is smaller than or equal to the file size of the original file, updating the original file to the file to be updated; S204: Generate a file update event message based on the file information and update status of the file to be updated; S205, based on the message queue module, sending the file update event message to the message queue corresponding to the file update; S206: Based on the user resource management module, obtain the file update event message from the message queue, and based on the file update event message, update the file storage space quota of the user.

[0044] In one embodiment, when a user performs a file update operation (e.g., uploading a new version of a file) through an operation interface, the system will receive a file update request. The system will verify the user's authority and determine the specific file that needs to be updated, including identifying the unique identifier of the file, such as the file name or ID.

[0045] In one embodiment, the system calls the file operation interface to obtain the original version information of the file to be updated, including its size, and then compares the file size of the original file with the size of the file to be updated to determine whether the user's available storage space quota can meet the capacity requirement after replacing the new file.

[0046] In one embodiment, if the file size of the file to be updated is less than or equal to the file size of the original file, the system replaces the original file with the new version, including rewriting the file content to the storage device and updating the file-related metadata (such as modification date, version number, etc.).

[0047] In one embodiment, after the file update is completed, a file update event message is generated based on the updated file information and update status, including information such as the updated file name, new version number, file size before update, and file size after update.

[0048] In one embodiment, the generated file update event message will be sent to a specific queue in the message queue module. This queue is used to process events related to file updates and ensure that all system components that need to be updated can receive this event. The message queue ensures the order of messages and the stability of the system, and provides a buffer to reduce the direct communication pressure of system components.

[0049] In one embodiment, the user resource management module monitors the messages about file updates in the message queue. When an update event message is detected, the message is extracted from the queue. Then, the user resource management module updates the user's file storage space quota according to the content of the message. If the updated file is smaller than the original file, the user's available storage space will increase; if the updated file is larger than the original file, the user's available storage space will decrease.

[0050] Furthermore, after comparing the file sizes of the original file and the file to be updated based on the file information of the original file, the method also includes: when the file size of the file to be updated is larger than the file size of the original file, obtaining the remaining storage amount of the file storage space of the user; when the difference between the file size of the file to be updated and the file size of the original file is smaller than the remaining storage amount, updating the original file to the file to be updated; based on the file information and update status of the file to be updated, generating the file update event message; based on the message queue module, sending the file update event message to the message queue corresponding to the file update; based on the user resource management module, obtaining the file update event message from the message queue, and updating the file storage space amount of the user based on the file update event message.

[0051] In one embodiment, if the file size of the file to be updated is larger than the file size of the original file, first check whether the remaining amount of the user's file storage space is sufficient to store the new file. The remaining amount check is to prevent the user from updating the file when the storage space is insufficient, and to ensure the feasibility of the update.

[0052] In one embodiment, if (file size of the file to be updated - file size of the original file) < (storage capacity quota of the file storage space - used storage capacity), where the storage capacity quota of the file storage space - used storage capacity is the remaining storage quota of the file storage space, then the original file is replaced with the new version. Otherwise, an error message is returned to inform the user that the storage space is insufficient and the update cannot be completed.

[0053] In one embodiment, after the file update is completed, the system will generate a file update event message based on the updated file information and update status, which may include information such as the updated file name, new version number, file size before update, file size after update, and update status.

[0054] In one embodiment, the generated file update event message will be sent to a specific queue in the message queue module. This queue is used to process events related to file updates to ensure that all system components that need to be updated can receive the event.

[0055] In one embodiment, the user resource management module monitors the messages about file updates in the message queue. When an update event message is detected, the message is extracted from the queue. Then, the user resource management module updates the user's file storage space quota according to the content of the message. If the updated file is larger than the original file, the corresponding difference is subtracted from the user's available storage space.

[0056] In a specific embodiment, the business module calls the file replacement interface of the above-mentioned file operation interface, and the interface calls the file information acquisition interface of the above-mentioned file storage module to obtain the original file information, and compares it with the new file. If the new file is larger than the original file, the user resource management module is called to obtain the user file storage capacity quota interface and the user used file storage capacity quota interface to obtain the current user storage space quota and the used quota, and check whether the difference between the remaining quota and the file size can store the current file. If the limit is exceeded, an error message is returned. If the new file is smaller than the original file, or the storage quota can meet the file storage, the file is updated through the file update interface; after the file is updated, a file update message notification is generated according to the original file information and the new file information, and sent to the message queue of the corresponding topic through the message publishing interface of the above-mentioned message queue module.

[0057] In one embodiment, the user resource management module subscribes to the file update event message in the message queue module, obtains the difference in file size, and adjusts the user's used storage space file storage usage quota.

[0058] See also Figure 3 , Figure 3 It is a schematic flow chart of a method for managing file storage space in a SAAS platform provided in an embodiment of the present application.

[0059] like Figure 3 As shown, the method for managing file storage space in the SAAS platform specifically includes steps S301 to S305.

[0060] S301, upon receiving a file deletion request from a user, calling the file operation interface based on a business module; S302: Based on the file operation interface, call the file information acquisition interface of the file storage module to acquire file information of the file to be deleted, and call the file deletion interface of the file storage module to delete the file to be deleted; S303: Generate a file deletion event message based on the file information and deletion status of the file to be deleted; S304: Based on the message queue module, send the file deletion event message to the message queue corresponding to the file deletion; S305: Based on the user resource management module, obtain the file deletion event message from the message queue, and based on the file deletion event message, update the file storage space quota of the user.

[0061] In one embodiment, when a user initiates a file deletion request, the request is usually triggered through a user interface, such as clicking a delete button. After receiving the request, the system calls the corresponding file operation interface according to the needs of the business module. This interface is pre-defined and is used to perform file-related operations. The system will determine whether the user has the authority to delete the file based on the current business process (business module) and which file operation interface needs to be called to perform the deletion operation.

[0062] In one embodiment, the file operation interface is used to call the file information acquisition interface of the file storage module to obtain detailed information of the file to be deleted, such as the file name, path, size, etc. Then, the file deletion interface of the file storage module is called to actually delete the file from the storage medium.

[0063] In one embodiment, during the deletion process, the system checks whether the file exists and its deletion status to ensure the correctness of the operation.

[0064] In one embodiment, after a file is successfully deleted, the system generates a file deletion event message based on the file information and deletion status of the file to be deleted. This message contains all necessary information about the deletion operation for use in subsequent steps. It can include basic information about the file, such as the file name, path, size, and the timestamp of the deletion operation.

[0065] In one embodiment, the system sends the generated file deletion event message to a corresponding message queue.

[0066] In one embodiment, the user resource management module listens to and obtains file deletion event messages from the message queue. After obtaining the message, the module updates the user's file storage space quota based on the file information in the message, including reducing the user's storage quota or releasing corresponding storage resources.

[0067] In a specific embodiment, the business module calls the file deletion interface of the above-mentioned file operation interface, and the interface calls the file information acquisition interface of the above-mentioned file storage module to obtain the file information, and then deletes the file through the file deletion interface. After deleting the file, a file deletion message notification is generated and sent to the message queue of the corresponding topic through the message publishing interface of the above-mentioned message queue module.

[0068] In one embodiment, the user resource management module subscribes to the file deletion event message in the message queue module, obtains the deleted file information, and reduces the user's used storage space quota.

[0069] In the above embodiment, it is ensured that files are correctly removed from storage, system components are notified, and the user's storage space quota is updated in a timely manner, thereby reducing data loss and quota management errors and providing users with a smooth and reliable service experience.

[0070] In one embodiment, through a public file operation interface, the business module only needs to call the interface corresponding to the current file operation. There is no need to handle the user storage space quota management separately, nor is there any need to handle the differences in file storage modules. This simplifies the file operation logic of the business module and improves management efficiency.

[0071] Furthermore, after obtaining the file storage event message from the message queue based on the user resource management module and updating the file storage space quota of the user based on the file storage event message, it also includes: when a preset storage capacity statistics time arrives, calling the storage capacity calculation interface of the file storage module, counting the storage space usage information of each user, and updating the file storage space quota of each user.

[0072] In one embodiment, to achieve decoupling, message notifications of file operations are sent asynchronously through a message queue. If a message queue failure or a network failure occurs, the user's used storage space quota may be incorrectly updated. Therefore, the user resource management module periodically calls the storage capacity calculation interface of the above-mentioned file storage module, re-counts the storage space usage quota of each user, and updates it to the persistent storage information.

[0073] See also Figure 4 , Figure 4 The embodiment of the present application provides a schematic block diagram of a file storage space management device in a SAAS platform, and the file storage space management device in the SAAS platform is used to execute the aforementioned file storage space management method in the SAAS platform.
