Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

With the development of network technology, the distributed file system is widely applied to file, data and information storage in various technical fields. The distributed file system comprises a storage server and a host, and typically, when a user performs basic operations (such as file creation, renaming, state inquiry, deletion, etc.) on the host, the host will transmit these basic operation requests to the corresponding storage server through a network, and after the storage server receives the basic operation requests and completes the basic operations, the storage server will transmit the operation results to the host sending the requests through the network. Taking the state information inquiry of a file as an example, when a user performs the state information inquiry operation of the file on a host, the host transmits a state information inquiry request of the file to a corresponding storage server through a network, and after the storage server receives the inquiry request and finishes the state information inquiry of the file, the storage server transmits an inquiry result to the host which transmits the inquiry request through the network.

However, in the above-mentioned inquiry process, the time delay of network transmission and the time consumption of inquiring the disk by the server account for a large proportion of the time consumption of inquiring the state information of the whole file. Especially, when the status information of a large number of files is queried, the proportion of network transmission delay and disk query time consumption is gradually increased. Therefore, when the method is used for inquiring a large quantity of files, the inquiry efficiency is low. The present application aims to solve this problem.

After the background technology of the information query method provided by the embodiment of the present application is introduced, an implementation environment related to the information query method provided by the embodiment of the present application will be briefly described below. The information query method provided by the embodiment of the application can be applied to the distributed file system shown in figure 1. The distributed file system includes a plurality of storage servers 101, a terminal 102, and a switch 103, and the terminal 102 performs data transmission with the storage servers 101 through the switch 103. In general, when a user performs a basic operation (such as creation, renaming, status query, and deletion of a file) on the terminal 102, the terminal 102 transmits the operation request to the corresponding storage server 101 through a network, and the storage server 101 packages the operation result after completing the operation requested by the terminal 102 and transmits the operation result to the terminal 102 through a communication network.

After the application scenario of the information query method provided by the embodiment of the application is introduced, the information query process is mainly introduced below.

In one embodiment, as shown in fig. 2, an information query method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:

S201, acquiring a query command input by a user.

The inquiry command is a command which is input into the terminal by a user when related information of the file needs to be inquired; for example, in a Linux operating environment, a user entering a "stat" command may query for information about a file.

In the embodiment of the application, if the user needs to inquire the related information of the file, an inquiry command can be input on the terminal. Optionally, a corresponding application program is installed on the terminal, an input interface or an input window for inquiring the command is provided, and the user can input the inquiring command on the interface or the input window of the terminal in a text input mode or input the inquiring command on the interface of the terminal in a control triggering mode; alternatively, the user may input the query command on the terminal in a voice manner. After the terminal obtains the query command input by the user, the subsequent query operation can be performed.

S202, reading the related information of the first target file corresponding to the query command from the related information of the batch files stored in the local cache in advance.

The related information of the batch files is information returned by the storage server according to a query request of the second target files sent by the terminal, and the batch files comprise the second target files and a plurality of files related to the second target files; the first target file is a file queried by a query command input by a user at the time. The related information of the file includes at least one of status information of the file, storage information of the file, type information of the file, and the like. Wherein the status information of the file includes a file name, a file size, an index number of the file, a modification time of the file, and the like. The first target file is an associated file of the second target file, for example, the first target file and the second target file belong to the same father directory; or the first target file and the second target file are stored in the same disk position or adjacent disk positions; or the first target file and the second target file belong to the same type of file; alternatively, the first target file and the second target file are files stored simultaneously.

In the embodiment of the present application, before reading the related information of the first target file corresponding to the query command, the related information of the batch file needs to be stored in the terminal in advance, and the method for storing the related information of the batch file is described below: the user inputs a query command of the second target file at the terminal, the terminal receives the query command and transmits the query command to a corresponding storage server through a network, the storage server packages the queried second target file and related information of the file related to the second target file and transmits the package to the terminal through the network, and the terminal stores the information in a local cache after receiving the second target file and related information of the file related to the second target file.

Further, after the terminal acquires the query command of the first target file input by the user again, the identifier of the first target file is extracted from the query command, and according to the mapping relationship between the file identifier and the related information, the related information of the batch files corresponding to the identifier of the first target file is searched in the local cache. It should be noted that, the mapping relationship between the file identifier and the related information may be predetermined.

According to the information query method provided by the embodiment of the application, the query command input by the user is firstly obtained, and then the related information of the first target file corresponding to the query command is read from the related information of the batch files stored in advance in the local cache. The method aims at the distributed storage system, when the terminal is used for reading batch files, the related information of the required files can be directly read from the local cache of the terminal, the terminal is not required to send query instructions corresponding to each file to the storage server, and the data of the memory or the disk on the storage server is not required to be read, namely the data cannot be influenced by the time delay of network transmission data in the distributed storage system and the time consumption of reading the data on the memory or the disk, so that the query efficiency of the file information is greatly improved.

In one embodiment, the process of acquiring the related information of the first target file may be described based on the embodiment shown in fig. 2, as shown in fig. 3, the reading the related information of the first target file corresponding to the query command from the related information of the batch files stored in advance in the local cache in S202 may include:

s301, extracting a target identifier of a first target file from the query command.

Wherein the object identifier is used to uniquely characterize the object file, and may be represented by one of text, letters, symbols, numbers, or by a combination of text, letters, symbols, numbers.

In the embodiment of the application, when the terminal acquires the query command input by the user, the target identifier of the first target file can be further extracted from the query command, so that the related information of the first target file can be acquired according to the target identifier. It should be noted that, the target identifier of the first target file in the query command may be an identifier generated by editing through a text input manner when the user inputs the query command on the terminal, or may be a file identifier automatically associated with the terminal when the user inputs the file name through a text manner.

S302, according to the type of the first target file, determining the related information of the first target file corresponding to the target identifier from the related information of batch files stored in the local cache in advance.

The target files may include text type files, video type files, and audio type files, among others. Or the type of the target file may be determined according to the storage time of the file, for example, the target file includes files of different storage times.

In the embodiment of the application, after the terminal extracts the target identifier of the first target file according to the query command, the terminal can further determine the type of the first target file, determine the storage area corresponding to the type from the local cache, and then search the related information of the batch files corresponding to the target identifier of the first target file from the storage area according to the mapping relation between the file identifier and the related information. It should be noted that, the mapping relationship between the file identifier and the related information may be predetermined.

Optionally, after extracting the target identifier of the first target file according to the query command, the terminal may first traverse the related information of the batch files stored in the local cache in advance according to the type of the first target file required to be queried by the user, screen the related information of the batch files with the same type as the first target file from the related information, and further search the related information of the batch files corresponding to the target identifier of the first target file from the screened related information of the batch files according to the mapping relationship between the file identifier and the related information. It should be noted that, the mapping relationship between the file identifier and the related information may be predetermined.

According to the method for reading the related information of the first target file, the information is searched from the local cache through the type of the first target file and the target identifier of the first target file, so that the searching range can be reduced, and the information searching efficiency is improved.

In one embodiment, a description may be made of a process of determining, based on the embodiment shown in fig. 3, the related information of the first target file corresponding to the target identifier from the related information of the batch files stored in advance in the local cache according to the type of the first target file, and "determining, based on the type of the first target file, the related information of the first target file corresponding to the target identifier from the related information of the batch files stored in advance in the local cache" in S302, as shown in fig. 4, includes:

s401, according to the type of the first target file, determining a storage area corresponding to the type from the local cache.

In the embodiment of the application, when the terminal determines the type of the first target file, the storage area corresponding to the type of the first target file is determined according to the corresponding relation between the type and the storage area. It should be noted that, the correspondence between the type and the storage area may be obtained by dividing the storage area for the related information of the batch file according to the type when the terminal obtains the related information of the batch file in advance. Specifically, when the terminal obtains the related information of the batch files, the local cache may be divided into storage areas according to the types of the files, so that different storage areas store different types of files, for example, the 1# storage area stores the files of the video type and the #2 area stores the files of the text type.

S402, determining relevant information of the target file corresponding to the target identifier from the storage area corresponding to the type.

In the embodiment of the application, when the terminal determines the storage area corresponding to the type from the local cache, according to the target identifier of the first target file, the terminal determines the related information of the target file corresponding to the target identifier from the storage area according to the corresponding relation between the target identifier and the identifiers of the files in the storage area. It should be noted that, the correspondence between the target identifier and the identifier of each file in the storage area may be previously obtained by constructing, by the terminal, related information of the batch of files in each type of storage area according to the target identifier of the file when the terminal obtains the related information of the batch of files.

According to the method for reading the related information of the first target file, the storage area can be rapidly positioned according to the type of the first target file, so that the searching range is reduced, related information searching is performed on the basis of the storage area after the range is reduced according to the target identification of the first target file, and the information searching efficiency can be improved.
