Problems solved by technology

Embedded devices are relatively rich in hardware storage resources, and have relatively small restrictions on the use of databases. However, for devices with scarce hardware resources, the use of databases is limited by the size of the burning files and the size of the memory, so it is difficult to realize the storage of a large number of files.

[0004] Although the current NAS products are equipped with relatively abundant hardware resources and can use a powerful relational database like sqlite, this increases the hardware cost of the product

Embodiment 1

[0045] This embodiment discloses a kind of file classification retrieval method based on KV database, comprising:

[0046] Step 1: Create a corresponding number of folders in advance according to the number of file types, each folder stores multiple database files, and multiple database files under each folder are used to record file information of a file type .

[0047] Specifically, the database files under each folder only record the corresponding type of file information. Moreover, N database files are created in each folder; in this embodiment, the database files in each folder are numbered from 0 to N-1, where N is an integer, and the reasonable value range is 5-100 , but not limited to this range, take N to be 11 in this example.

[0048] The database files are all KV database files, including multiple key-value pairs (Key-Value). Among them, the key (Key) is used to record the file path, and the value (Value) is used to record the number of files under the correspon...

Embodiment 2

[0061] The purpose of this embodiment is to provide a kind of file classification retrieval system based on KV database, comprising:

[0062] The folder creation module creates a corresponding number of folders in advance according to the number of file types;

[0063] A database file creation module, each folder stores multiple database files, and the multiple database files under each folder are used to record file information of a file type;

[0064] The database file editing module writes the file information of all files into the database file in the corresponding file type folder;

[0065] The file query module receives a file type query request and performs file query according to the database file.

Embodiment 3

[0067] The purpose of this embodiment is to provide an electronic device.

[0068] An electronic device, comprising a memory, a processor, and a computer program stored on the memory and operable on the processor, when the processor executes the program, the following steps are implemented, including:

[0069] Create a corresponding number of folders in advance according to the number of file types, each folder stores multiple database files, and multiple database files under each folder are used to record file information of a file type;

[0070] Write the file information of all files into the database file in the corresponding file type folder;

[0071] Receive file type query requests, and perform file query based on database files.

Abstract

The invention discloses a file classification retrieval method and system based on a KV database. The method comprises the steps: creating folders with the corresponding number in advance according tothe number of file types, and storing multiple database files in each folder, wherein the multiple database files in each folder are used for recording file information of one file type; writing thefile information of all the files into database files in corresponding file type folders; and receiving a file type query request, and performing file query according to the database file. According to the method, on the basis of a small and efficient KV database and optimization of memory usage, classification retrieval of a large number of files is achieved under the condition that hardware resources are limited, and the hardware cost of NAS products is reduced.

Description

technical field [0001] The invention belongs to the technical field of database retrieval, and in particular relates to a file classification retrieval method and system based on a KV database. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] NAS (network attached storage) is a dedicated data storage server that enables users to access data conveniently through the network, and unlike cloud disks, its storage medium is actually in the hands of users, with good confidentiality and safety. In order to manage a large number of files stored by users, it is generally necessary to classify the files to facilitate users to retrieve different types of files. Generally speaking, NAS will use a database to implement file classification. Embedded devices are relatively rich in hardware storage resources, so the restrictions on the use of databases...
