[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0029] In order to solve the technical problems in the prior art that edge nodes consume a lot of input and output resources when updating resources and the system performance is complex, the present application provides a data management method for edge nodes, which can achieve the effect of reducing system load.

[0030] Figure 1 This is a flow chart of a data management method for an edge node provided in an embodiment of the present application. Figure 1 As shown, the data management method of the edge node includes:

[0031] S102, when receiving a file management instruction, determining target data requested to be managed by the file management instruction, wherein the file management instruction is used to add or delete target data;

[0032] S104, searching for the sqlite file of the sqlite database on the edge node;

[0033] S106: When the sqlite file is found, the target data is stored in the sqlite file or the target data is deleted from the sqlite file.

[0034] The above-mentioned lightweight database sqlite database is a lightweight relational database management system that occupies very few resources, and only a few hundred KB of memory is required. The data of the sqlite database is stored in a sqlite file.

[0035] In this embodiment, a sqlite file is added to the edge node. The sqlite file includes a calling interface. By calling the interface, data can be stored in the sqlite file or deleted from the sqlite file.

[0036] The above-mentioned edge nodes can be edge nodes under the content distribution network, and the edge nodes can be routers in household, network data boxes, etc. For household routers and network data boxes, the performance is low and cannot carry a large amount of data input and output. Therefore, the sqlite file of the sqlite database can be configured on the edge node, and the data resources on the edge node can be stored through the sqlite file.

[0037] The above-mentioned file management instruction can be an instruction generated by the content distribution network according to the popularity of the data. If the content distribution network wants to store certain popular data in a certain edge node, it will initiate a file management instruction and require that the data be added to the edge node as target data. The edge node receives the file management instruction and stores the target data in the sqlite file.

[0038] The above sqlite file can be stored in any location of the edge node. Since the edge node is a physical hardware device, the sqlite file can be configured in the physical hardware device. Whether the physical hardware device includes other programs in addition to the sqlite file and the program of the edge node itself is not limited in this embodiment.

[0039] In this application, for edge nodes, if a file management instruction for adding or deleting target data is received, the sqlite file of the sqlite database is searched on the edge node, and the sqlite file stores the resources stored by the edge node. When the sqlite file is found, the target data is stored in the sqlite file or the target data is deleted from the sqlite file, so that the resources of the edge node can be stored by configuring the sqlite file on the edge node, reducing input and output operations, reducing the consumption of input and output resources, and reducing the system performance load.

[0040] The sqlite file is opened synchronously when the edge node is started. After opening, the edge node searches for the location of the sqlite file when receiving the file management instruction. After finding the location of the sqlite file, it records the location. If there is no sqlite file at the location, it creates a sqlite file. When receiving the file management instruction again, it directly performs operations on the sqlite file at the location.

[0041] As an alternative example, Figure 2 As shown, the sqlite files for finding the sqlite database on the edge node include:

[0042] S202-1, when the sqlite file is stored in a program folder of the edge node, obtain a storage path of the pre-stored sqlite file, and determine the file under the storage path as the sqlite file, wherein the program folder is used to store the running program of the edge node;

[0043] S202-2, when the sqlite file is stored outside the program folder of the edge node, traverse all folders of the edge node according to the file name of the sqlite file until the sqlite file is found.

[0044] In this embodiment, since the sqlite file may be stored in any location of the edge node, ideally, the location of the file can be marked when configuring the sqlite file to the edge node. For example, the sqlite file is configured in the program folder where the program of the edge node is located, then the storage path is known, and the sqlite file can be found according to the storage path. If the sqlite file is issued, the storage location may be anywhere in the edge node. Therefore, at this time, all folders of the edge node can be traversed according to the file name of the sqlite file until the sqlite file is traversed or all folders are traversed.

[0045] As an alternative example, Figure 3As shown, when the sqlite file is found, storing the target data into the sqlite file or deleting the target data from the sqlite file includes:

[0046] S302, in the case of newly added target data, calling an application program interface to locate the first position where the target data should be inserted;

[0047] S304, in the case of deleting the target data, calling an application program interface to locate the second position of the target data in the sqlite file.

[0048] In this embodiment, since the file management instruction is used to add target data or delete target data, different positions are to be searched in the sqlite file for different situations. For the case of adding target data, the first position where the target data should be inserted is located, and for the case of deleting target data, the target data is searched in the sqlite file and located at the second position where the target data is located.

[0049] The location can be called by the application program interface, which is an interface directly integrated into the program during compilation, through which operations are performed on the sqlite file.

[0050] As an alternative example, Figure 4 As shown, in the case of adding new target data, calling the application program interface in the sqlite file to locate the first position where the target data should be inserted includes:

[0051] S402, determining the data type of the target data;

[0052] S404, determining the position after the last data of the data type in the sqlite file as the first position, or determining the position before the last data of the data type in the sqlite file as the first position, wherein data of the same data type are aggregated and distributed in the sqlite file.

[0053] In this embodiment, data of different data types can be stored in different locations in the sqlite file. Data of different data types are centrally distributed in the sqlite file. For example, taking two data types as an example, data of data type 1 is stored in the first half of the sqlite file, and data of data type 2 is stored in the second half of the sqlite file. If new data is added, the target data is inserted into the data corresponding to the data type, after the last data. Alternatively, if the last data is template data, the target data is inserted before the last data.

[0054] As an alternative example, Figure 5As shown, in the case of adding new target data, calling the application program interface in the sqlite file to locate the first position where the target data should be inserted includes:

[0055] S502, determining the data type of the target data;

[0056] S504, determining the position after the first data of the data type in the sqlite file as the first position, or determining the position before the first data of the data type in the sqlite file as the first position, wherein the data of the same data type are dispersed in the sqlite file.

[0057] In this embodiment, data distribution of different data types can be stored in different locations in the sqlite file. For example, data of one data type is dispersed in the sqlite file and adjacent to data of other data types. Taking two data types as an example, the sqlite file starts from the beginning of the data part, and the order can be data of data type 1, data of data type 2, data of data type 2, data of data type 1, data of data type 2, data of data type 1, data of data type 2, data of data type 1, and so on. The data of the two data types are not obviously concentrated together, but are dispersed.

[0058] At this time, if new target data is added, the target data can be inserted into the data of the data type, before or after the first data, or inserted into the data of the data type, before or after a selected data. The selected data can be data with the same data length as the target data.

[0059] As an optional example, when a sqlite file is found, storing the target data in the sqlite file includes: determining the size of the available storage space of the edge node; when the data size of the target data exceeds the size of the available storage space, prohibiting the target data from being stored in the sqlite file; or, when the data size of the target data exceeds the size of the available storage space, deleting the data with the lowest number of accesses in the sqlite file until the size of the available storage space exceeds the data size of the target data.

[0060] In this embodiment, considering that the edge node is a local device, the storage space has an upper limit. Therefore, when adding new target data, it is possible to check whether the available storage space of the edge node is sufficient. The sqlite file will become larger after storing the target data, so it is necessary to ensure that the sqlite file can still be stored in the edge node after storing the target data, and will not hesitate to store the sqlite file in the edge node due to the increase in size. If the available storage space is insufficient, it is possible to prohibit the storage of the target data or delete some data in the sqlite file until the available space is sufficient.

[0061] As an optional example, when a sqlite file is found, storing the target data in the sqlite file includes: determining a preset storage condition of the edge node; and storing the target data in the sqlite file when the target data meets the preset storage condition.

[0062] In this embodiment, the storage requirements of the sqlite file can be set, such as what type of data to store, when the data is generated, how much data to store, etc. If the target data does not meet the preset storage conditions, the target data may not be stored, and only the data that meets the preset storage conditions will be stored in the sqlite file.

[0063] Figure 6 This is a system diagram of this embodiment. On the edge node, when the edge node is started, the relevant file information must be loaded, that is, the information of the data shared by the central node must be loaded. The sqlite management module calls the application program interface in the sqlite file to operate the sqlite file, takes out the data information and returns it to the edge node management module. When adding or deleting data, the edge node management module calls the application program interface in the sqlite file through the sqlite management module to add or delete data, and receives the result returned by the sqlite management module.

[0064] Figure 7 This is a schematic diagram of the structure of a data management device for an edge node provided in an embodiment of the present application. Figure 7 As shown, the data management device of the edge node includes:

[0065] A determination module 702 is used to determine the target data requested to be managed by the file management instruction when a file management instruction is received, wherein the file management instruction is used to add or delete the target data;

[0066] A search module 704 is used to search for a sqlite file of a sqlite database on an edge node;

[0067] The processing module 706 is used to store the target data into the sqlite file or delete the target data from the sqlite file when the sqlite file is found.

[0068] The above-mentioned lightweight database sqlite database is a lightweight relational database management system that occupies very few resources, and only a few hundred KB of memory is required. The data of the sqlite database is stored in a sqlite file.

[0069] In this embodiment, a sqlite file is added to the edge node. The sqlite file includes a calling interface. By calling the interface, data can be stored in the sqlite file or deleted from the sqlite file.

[0070] The above-mentioned edge nodes can be edge nodes under the content distribution network, and the edge nodes can be routers in household, network data boxes, etc. For household routers and network data boxes, the performance is low and cannot carry a large amount of data input and output. Therefore, the sqlite file of the sqlite database can be configured on the edge node, and the data resources on the edge node can be stored through the sqlite file.

[0071] The above-mentioned file management instruction can be an instruction generated by the content distribution network according to the popularity of the data. If the content distribution network wants to store certain popular data in a certain edge node, it will initiate a file management instruction and require that the data be added to the edge node as target data. The edge node receives the file management instruction and stores the target data in the sqlite file.

[0072] The above sqlite file can be stored in any location of the edge node. Since the edge node is a physical hardware device, the sqlite file can be configured in the physical hardware device. Whether the physical hardware device includes other programs in addition to the sqlite file and the program of the edge node itself is not limited in this embodiment.

[0073] In this application, for edge nodes, if a file management instruction for adding or deleting target data is received, the sqlite file of the sqlite database is searched on the edge node, and the sqlite file stores the resources stored by the edge node. When the sqlite file is found, the target data is stored in the sqlite file or the target data is deleted from the sqlite file, so that the resources of the edge node can be stored by configuring the sqlite file on the edge node, reducing input and output operations, reducing the consumption of input and output resources, and reducing the system performance load.
