Fig. 1 illustrates an exemplary system architecture 100 to which the file operation request processing method or file operation request processing apparatus of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include first servers 101, 102, 103, a second server 104, and a third server 105.
The first servers 101, 102, 103 may interact with the second server 104, for example, sending file operation requests, receiving information, and the like. The first servers 101, 102, and 103 may be independent servers, virtual dedicated servers established based on the second server 104, or containers established based on the second server 104.
The second server 104 may be various types of servers that provide various services, such as a database server, a high performance computing server, and the like. The second server 104 may perform processing such as analysis on data such as the received file operation request, and interact with the third server 105 based on the processing result, for example, perform operation on a file managed by the third server 105.
The third server 105 may be a server that provides various services, such as a file management server that provides file storage and management services. The file management server can manage and schedule the storage space of the file, and provides the logical structure, the physical structure, the storage method and the mapping from the identifier to the actual address of the file; the control operation and the access operation of the file and the sharing of the file can be realized; reliable file security and protection measures and the like can also be provided.
It should be noted that the first servers 101, 102, 103, the second server 104 and the third server 105 may be the same server.
It should be noted that the file operation request processing method provided in the embodiment of the present application is generally executed by the second server 104, and accordingly, the file operation request processing apparatus is generally disposed in the second server 104.
It should be understood that the number of first servers, second servers, and third servers in fig. 1 is merely illustrative. There may be any number of first, second and third servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a file operation request processing method according to the present application is shown. The file operation request processing method comprises the following steps:
In this embodiment, an electronic device (for example, the second server 104 shown in fig. 1) on which the file operation request processing method operates may intercept a file operation request sent by another server (for example, the first servers 101, 102, 103 shown in fig. 1) connected to the electronic device, where the file operation request includes file path information of a file to which the file operation request is directed and a priority value indicating a priority of the file operation request, and the file operation request may be one or more. In practice, the first server may be one or more independent servers, or may be one or more virtual servers or containers constructed based on the electronic device. It should be noted that the file operation request can be used to request various operations on a file, such as opening a file, creating a file, deleting a file, establishing a synchronous link at another location for a file or directory, reading data from a file, writing data into a file, and so on. It should be further noted that the file path information may be a character string for describing a storage path of the file, where the character string may be composed of characters such as letters, numbers, symbols, and the like. In general, the file path information may further include a file name of the file. Further, the priority value may be any value (e.g., 1, 20, 100, etc.) for representing the priority of the file operation request.
It should be noted that the file for which the file operation request is directed may be a file managed in a server (for example, the third server 105 shown in fig. 1) connected to the electronic device and used for managing the file. In practice, the server for managing files may be a stand-alone server, or may be a file system in the electronic device. The file system may organize and allocate space of a file storage device (e.g., a magnetic disk, an optical disk, etc.) installed in the electronic device, and may also be responsible for storing files, protecting and retrieving stored files, and the like.
In some optional implementations of this embodiment, the file for which the file operation request is directed may be a directory file. The directory file may be configured to store a mapping relationship between a file name and an inode number. In practice, the index node number may be an identifier for indicating an index node, and the index node may be a data structure in an operating system, which contains various information related to a file, such as the time when a certain file was last accessed or modified, the size of the file, and the like.
In some optional implementations of this embodiment, the file for which the file operation request is directed may be a device file, where the device file may be a block device file that performs data transmission in units of blocks, such as a magnetic disk, an optical disk, and the like. In addition, the file to which the file operation request is directed may be a character device file.
In some optional implementations of the present embodiment, the file for which the file operation request is directed may be a common file, such as a plain text file, a binary file, a file in a data format, and so on. In addition, the file to which the file operation request is directed may also be a connection file, a pipe file, or the like.
In this embodiment, the electronic device may be preset with a path information set, where the path information set may include at least one piece of path information. Here, the path information may be a character string for describing a storage path of the file, or may be a regular expression set in advance based on the storage path of the file. In practice, the path information may also contain a file name. In addition, for each piece of path information in the path information set, the electronic device may store a preset priority value matching the path information, and pre-establish and store a mapping between the path information and the priority value, so that the electronic device finds the priority value matching each piece of path information based on the mapping. In practice, different types of files may be matched with different priority values. As an example, the priority value matched with the path information of the regular log file is 3, the priority value matched with the path information of the alarm log file is 2, and the like. It should be noted that different types of files may be matched with the same priority value.
In this embodiment, the electronic device may first extract any path information in the path information set; then, the electronic device may match the file path information received in step 201 with the extracted path information by using a character string matching method; in response to determining that the file path information matches the extracted path information, the electronic device may obtain a priority value matching the extracted path information based on the mapping and determine the extracted priority value as a target priority value; in response to determining that the file path information does not match the extracted path information, the electronic device may extract next path information that is not subjected to a matching operation from the set of path information and match the next path information with the file path information.
It should be noted that, after it is determined that the extracted path information matches with the file path information, the electronic device may not perform the matching operation of the next path information any more; otherwise, matching the path information which is not subjected to the matching operation in the path information set with the file operation information one by one until the matching is successful. In addition, if it is determined in sequence that all the information in the path information set do not match the file path information, the priority value received in step 201 is not operated.
It should be noted that the above string matching method is a well-known technology widely studied and applied at present, and is not described herein again.
In this embodiment, the electronic device may store a file operation request queue for storing file operation requests. The electronic device may first replace the priority value included in the file operation request received in step 201 with the target priority value determined in step 202; then, the file operation request received in step 201 is inserted into the file operation request queue, and the file to which the file operation request in the file operation request queue is directed is operated based on the size sequence of the priority numerical values included in the file operation requests in the file operation request queue.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the file operation request processing method according to the present embodiment. In the application scenario of fig. 3, first, the first servers 301, 302, 303 respectively send file operation requests 304, 305, 306 containing file path information and priority count values. Then, the second server 307 intercepts the file operation requests 304, 305, and 306, and determines path information in a preset path information set that matches the file path information included in each file operation request. Then, the second server 307 obtains preset target priority values matched with the determined path information, and replaces the priority values included in the file operation requests 304, 305, and 306 with corresponding target priority values, so as to obtain the replaced file operation requests 308, 309, and 310. Finally, the second server 307 stores the file operation requests 308, 309, and 310 in a file operation queue 311, so as to operate the file stored in the third server 312 and targeted by the file operation request in the file operation request queue 311.
The method provided by the embodiment of the application intercepts the file operation request comprising the file path information and the priority value, then determines the path information matched with the file path information from the preset path information set so as to determine the target priority value, finally replaces the priority value contained in the file operation request with the target priority value, and stores the file operation request into the file operation request queue, thereby realizing the resetting of the priority of the file operation request, so as to access the disk I/O resources according to a reasonable order, and improving the isolation effect of the disk I/O resource isolation.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a file operation request processing method is shown. The process 400 of the file operation request processing method includes the following steps:
In this embodiment, an electronic device (for example, the second server 104 shown in fig. 1) on which the file operation request processing method operates may intercept a file operation request sent by another server (for example, the first servers 101, 102, 103 shown in fig. 1) connected to the electronic device, where the file operation request includes file path information of a file to which the file operation request is directed and a priority value indicating a priority of the file operation request. It should be noted that the file for which the file operation request is directed may be a file managed in a server (for example, the third server 105 shown in fig. 1) connected to the electronic device and used for managing the file. It is noted that the file to which the file operation request is directed may be a directory file, a device file, a general file (e.g., a plain text file, a binary file, a file in data format, etc.), a connection file, a pipe file, and so on.
In this embodiment, the electronic device may preset a path information set, may further store a preset priority value matching each piece of path information, and previously establish and store a mapping between the path information and the priority value.
In this embodiment, the electronic device may first extract any path information in the path information set; then, the file path information can be matched with the extracted path information by using a character string matching method; in response to determining that the file path information matches the extracted path information, a priority value matching the extracted path information may be obtained based on the mapping and determined as a target priority value; in response to determining that the file path information does not match the extracted path information, extracting next path information which is not subjected to matching operation from the path information set, matching the next path information with the file path information, and repeating the steps until the matching is successful or no path information which is not subjected to matching operation exists in the path information set.
In this embodiment, the electronic device may store a file operation request queue for storing file operation requests. The electronic device may first replace the priority value included in the file operation request with the target priority value; and then, inserting the file operation request into the file operation request queue.
It should be noted that the specific operations in steps 401 to 403 are substantially the same as the specific operations in steps 201 to 203, and are not described herein again.
In this embodiment, after the file operation request is inserted into the file operation request queue, the electronic device may further determine whether other file operation requests except the file operation request exist in the file operation request queue; in response to determining that there are no remaining file operation requests, the file to which the file operation request is directed may be directly operated. Step 405 may be performed in response to determining that there are remaining file operation requests.
In this embodiment, in response to determining that at least one remaining file operation request other than the file operation request exists in the file operation request queue, the electronic device may update the priority value included in the remaining file operation requests. It should be noted that, for each remaining file operation request, the priority value included in the remaining file operation request may be used to indicate the priority of the remaining file operation request.
In some optional implementation manners of this embodiment, the electronic device may increase a priority value included in each of the at least one remaining file operation request by a first preset value, so as to update the priority value included in the remaining file operation request. The preset value may be any value.
In some optional implementation manners of this embodiment, the electronic device may first determine the remaining file operation requests with the priority value smaller than the second preset value, and then increase the priority value included in the determined remaining file operation requests by a preset third value, so as to update the priority value included in the remaining file operation requests. The second preset value and the third preset value may be any values.
In some optional implementation manners of this embodiment, the electronic device may further replace the priority value with a preset priority value that is preset and matches with the priority value, where the priority value is included in each of the at least one remaining file operation request. The preset priority value may be any value.
And 406, operating the files to which the file operation requests in the file operation request queue aim at according to the sequence of the priorities indicated by the priority numerical values from high to low.
In this embodiment, the electronic device may first rank the file operation requests in the file operation request queue according to a sequence from high to low of a priority indicated by a priority value; and then, operating the files for which the file operation requests aim at in sequence according to the arranged sequence. It should be noted that the file operation request can be used to request various operations on a file, such as opening a file, creating a file, deleting a file, establishing a synchronous link at another location for a file or directory, reading data from a file, writing data into a file, and so on.
In this embodiment, for each file operation request in the file operation request queue, the electronic device may further perform resource allocation for the file operation request, for example, set a throughput value when operating a file to which the file operation request is directed, an IOPS (Input/Output Operations Per Second), and the like. The electronic device may operate on the file to which the file operation request is directed based on the allocated resource.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the file operation request processing method in this embodiment highlights a step of updating the priority value included in the remaining file operation requests in the file request queue. Therefore, according to the scheme described in this embodiment, after the file operation request is inserted into the file operation request queue each time, the priority of the original file operation request can be set, so that the file to which the file operation request with a lower priority is directed cannot be operated. Therefore, the priority of the file operation request is further reset, so that the disk I/O resources are accessed according to a reasonable sequence, and the isolation effect of disk I/O resource isolation is further improved.
With further reference to fig. 5, as an implementation of the method shown in the above-mentioned figures, the present application provides an embodiment of a file operation request processing apparatus, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 2, and the apparatus may be specifically applied to various electronic devices.

In some optional implementation manners of this embodiment, the updating unit 505 may be further configured to increase a priority value included in each of the at least one remaining file operation request by a preset value.
In some optional implementations of the present embodiment, the file operation request processing apparatus 500 may further include an operation unit 506. The operation unit 506 may be configured to operate on the files in the file operation request queue according to the order from high to low of the priority indicated by the priority value.
