[0067] The technical solutions 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.

[0068] It should be understood that the "embodiments of the present application" or "the aforementioned embodiments" mentioned throughout the specification mean that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in the embodiments of the present application" or "in the aforementioned embodiments" appearing throughout the specification may not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the various embodiments of the present application, the size of the sequence numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. The above-mentioned sequence numbers of the embodiments of the present application are for description only and do not represent the advantages and disadvantages of the embodiments.

[0069] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0070] The present application embodiment provides an information processing method, which can be applied to a server, referring to Figure 1 As shown, the method may include the following steps:

[0071] Step 101: Receive an operation request for a distributed file system sent by a client.

[0072] In an embodiment of the present application, the server may receive an operation request for a distributed file system sent by a client through a transmission protocol. It should be noted that the operation request carries a message including an operation type. In an achievable manner, the transmission protocol may refer to a transmission control protocol / Internet protocol (TCP / IP). Exemplarily, a distributed file system may refer to a distributed file system based on an HDFS architecture, or a distributed file system based on a CEPH architecture, or a distributed file system of other architectures, which is not specifically limited here.

[0073] In the embodiment of the present application, the distributed file system includes a client of the distributed file system and a server of the distributed file system. It should be noted that one client corresponds to multiple servers, and the server of the distributed file system may refer to a metadata server (Meta Data Server, MDS) of the distributed file system.

[0074] Step 102: Based on the operation request, determine target information corresponding to the target operation on the distributed file system.

[0075] The target information is information about interfaces involved in one or more target nodes when executing a target operation on a distributed file system.

[0076] In an embodiment of the present application, the target operation may refer to a read operation or a write operation; the target information may refer to the information of the interface involved in one or more target nodes related to the read operation when the distributed file system performs a read operation, or the information of the interface involved in one or more target nodes related to the write operation when the distributed file system performs a write operation. Specifically, the target address can be determined according to the message carried in the operation request, and the call information of each interface corresponding to the target operation can be obtained from the target storage area based on the target address, and then the call information of each interface is aggregated to obtain the target information. Among them, the call information of the interface may include identification information and permission information of the interface, etc.

[0077] In an implementable manner, the target operation may also refer to a modification operation or a deletion operation.

[0078] It should be noted that the target node may include a client of the distributed file system and a server of the distributed file system involved in executing the target operation on the distributed file system.

[0079] Step 103: Send the target information to the client of the distributed file system through the target interface of the server, so that the target node responds to the operation request and executes the target action corresponding to the target operation.

[0080] In the embodiment of the present application, if the target operation is a read operation, the target action may refer to returning the required metadata; if the target operation is a write operation, the target action may refer to creating metadata.

[0081] In an embodiment of the present application, a target interface can be determined from multiple interfaces of the server based on the message carried in the operation request. After that, the target information and the operation request can be sent to the client of the distributed file system (i.e., the file system client) through the target interface, so that the target node responds to the operation request and returns the metadata required by the user end or creates corresponding metadata.

[0082] In one achievable manner, the target interface may be determined from a plurality of interfaces to be screened of the server according to the operational fatigue of the target operation.

[0083] It should be noted that when sending information to the client of the distributed file system, it is not necessary to carry a complete operation request, and it is only necessary to send information that can identify the operation request. For example, identification information, a serial number or a session ID, etc. can be sent, and it is only necessary to reflect what specific operation needs to be performed. The embodiment of the present application does not specifically limit this. In the embodiment of the present application, by aggregating the interface information involved in one or more target nodes of the distributed file system corresponding to the target operation, the distributed file system can directly execute and complete the corresponding target action at one time according to the aggregated information, without the need to perform the corresponding action multiple times to complete the operation request as in the related art. This not only improves the processing speed of the operation request, but also significantly reduces the time delay in the execution of the operation.

[0084] The information processing method provided in the embodiment of the present application can receive an operation request for a distributed file system, and aggregate information of all interfaces involved in performing a target operation on the distributed file system into target information, and then based on the target information, call the distributed file system through the target interface to perform the target operation, that is, when the distributed file system performs the target operation, it only needs to call the distributed file system once, instead of calling the distributed file system multiple times as in the related art, which solves the problem of high time delay when performing a read operation or a write operation on the distributed file system in the related art, thereby improving the efficiency of reading or writing metadata.

[0085] Based on the above embodiments, the embodiments of the present application provide an information processing method, which can be applied to a client of a distributed file system. Figure 2 As shown, the method may include the following steps:

[0086] Step 201: Receive an operation request for a distributed file system and target information corresponding to a target operation sent by a server through a target interface of a client.

[0087] The target information is information about interfaces of one or more target nodes involved in executing the target operation, and is determined by the server based on the operation request.

[0088] In the embodiments of the present application, Figure 3 As shown, the distributed file system includes a client of the distributed file system and a server of the distributed file system; and the gateway may include a server and a distributed file system.

[0089] The network management may refer to an SMB gateway or an NFS gateway. It should be noted that the embodiment of the present application does not impose any restrictions on the type of gateway applicable to the present solution, and SMB and NFS are only exemplary.

[0090] In one achievable manner, the TCP / IP protocol may be used to receive the operation request and target information for the distributed file system through the target interface of the client.

[0091] Step 202: If it is determined that the operation request can be processed, a target action corresponding to the target operation is executed based on the target information, and feedback information for the target operation is sent to the server.

[0092] In an embodiment of the present application, the client may determine whether it can process the operation request based on the type of the operation request. If the client determines that it can process the operation request, it may directly perform the target operation based on the target information.

[0093] In one achievable manner, if the operation request is to read data from a distributed file system, the client can determine whether the data to be read exists in the cache. If it is determined that the corresponding data exists in the cache, the read operation can be directly performed according to the target information, that is, the corresponding data can be read from the cache. It should be noted that the cache can refer to a consistent cache in the client of the distributed file system.

[0094] It should be noted that if the target action corresponding to the target operation is successfully executed, all the metadata read or feedback information indicating that the write operation is successfully executed can be sent to the server; if the target operation is not successfully executed, feedback information indicating that the target operation is not successfully executed can be sent to the server.

[0095] According to the information processing method provided by the embodiment of the present application, the client of the distributed file system can receive the operation request sent by the server and the target information of the interface of the target node involved in executing the target operation through the target interface. Afterwards, if the client determines that it can process the operation request, it can directly execute the target action corresponding to the target operation based on the target information. In this way, the distributed file system can execute the target operation after receiving one operation request from the server, instead of needing to receive multiple operation requests from the server before executing the target operation as in the related art. This solves the problem of high time delay when executing read operations or write operations on the distributed file system in the related art, thereby improving the efficiency of reading or writing metadata.

[0096] Based on the above embodiments, the embodiments of the present application provide an information processing method, referring to Figure 3 As shown, the method may include the following steps:

[0097] Step 301: The server receives an operation request for a distributed file system sent by a client.

[0098] In the embodiment of the present application, the operation request may be sent to the server in the form of a message. Figure 4 The network processing layer in the distributed file system establishes a communication connection between the server and the client and receives operation requests for the distributed file system.

[0099] Step 302: The server determines a target address based on the operation type of the target operation carried in the operation request and the target identifier corresponding to the target operation.

[0100] The target identifier is used to identify the data obtained after executing the target operation on the target node.

[0101] In an embodiment of the present application, the target address may refer to the address information of a storage area used to store target information; the target identifier may refer to the identifier of metadata obtained after performing a target operation on a target node, and the operation type may include a read operation (i.e., reading metadata from a distributed file system) and a write operation (i.e., writing metadata in a distributed file system).

[0102] It should be noted that the request message may refer to an SMB message or an NFS message. The embodiment of the present application does not impose any restrictions on the file system protocol type that can be applied to this solution. SMB and NFS are only exemplary.

[0103] In the embodiment of the present application, Figure 3The protocol processing layer in the method obtains the protocol command word from the message carrying the operation request, analyzes and processes the protocol command word, obtains the operation type of the target operation and the target identifier of the metadata obtained after executing the target operation, and then determines the target node involved in executing the target operation from multiple nodes of the distributed file system according to the operation type and the target identifier, and then determines the target address according to the information of the target node.

[0104] In the embodiment of the present application, step 302 can be implemented through steps 302a to 302c.

[0105] Step 302a: The server determines a target node from nodes of the distributed file system based on the operation type and target identifier of the target operation.

[0106] In an embodiment of the present application, if the operation type of the target operation is a read operation, the target node storing the metadata to be read can be determined from the nodes of the distributed file system according to the target identifier; if the operation type of the target operation is a write operation, the target node to which the metadata is to be written can be determined from the nodes of the distributed file system according to the target identifier.

[0107] It should be noted that the target node may be one or more.

[0108] Step 302b: The server determines a first address of a first area storing identification information of an interface of a target node.

[0109] In the embodiment of the present application, the identification information can be used to identify the interface of the target node, and the first area can refer to a part of the storage area in the server. Specifically, the first area where the identification information of the interface of the target node is stored can be determined from the storage area of ​​the server, and then the address of the first area (i.e., the first address) is determined.

[0110] In an implementable manner, the first area may refer to a storage area where a field of identification information is stored.

[0111] In other embodiments of the present application, the "identification information" in step 302b may be obtained through step 302b1.

[0112] Step 302b1: The server generates identification information of the interface based on the attribute information of the interface, and stores the identification information in the first area.

[0113] In an embodiment of the present application, the Internet Protocol (IP) address and interface name of each interface can be obtained, and then the IP address and interface name of each interface are written into a pre-set field according to the bit (hereinafter referred to as: bit), and then the field is stored in the first area.

[0114] Step 302c: The server determines a second address of a second area storing target parameters corresponding to the interface and an interface address of the interface.

[0115] The target parameter represents the authority information for the target node; the target address includes a first address and a second address.

[0116] In an embodiment of the present application, the target parameters may refer to the parameters required to call the interface. Specifically, the target parameters may include permission information for the target node, the data name of the metadata corresponding to the target operation, the operation type for the interface, and the configuration information of the interface; the interface address may refer to the return value address of the interface.

[0117] In the embodiment of the present application, the storage area of ​​the target parameter and the interface address can be determined from the storage area of ​​the server, and the address of the storage area (ie, the second area) is the second address. It should be noted that the second address can be a pointer address.

[0118] In other embodiments of the present application, the "target parameters and interface address" in step 302c may be obtained through steps 302c1 to 302c2.

[0119] Step 302c1: The server encodes the interface parameters corresponding to the interface to obtain target parameters, and stores the target parameters in the second area.

[0120] In the embodiment of the present application, the second area may refer to a pre-allocated pointer memory, and the interface parameters are the parameters required to call each interface. Specifically, the interface parameters corresponding to each interface may be encoded to obtain target parameters, and then the target parameters are stored in the pre-allocated pointer memory.

[0121] Step 302c2: The server encodes the address of the interface to obtain the interface address, and stores the interface address in the second area.

[0122] In an embodiment of the present application, the return value address of the interface can be encoded to obtain the interface address, and then the interface address is also stored in a pre-set pointer memory.

[0123] Step 303: The server obtains target information from the target storage area based on the target address.

[0124] The target information is information about interfaces involved in one or more target nodes when executing a target operation on a distributed file system.

[0125] In the embodiment of the present application, the target storage area may include different storage areas. Specifically, the target information may be obtained from different storage areas according to the target address.

[0126] In the embodiment of the present application, step 303 can be implemented through steps 303a to 303b.

[0127] Step 303a: The server obtains identification information from the first area based on the first address.

[0128] In the embodiment of the present application, identification information of the interface can be obtained from the field stored in the first area according to the determined first address.

[0129] Step 303b: The server obtains target parameters and an interface address from the second area based on the second address.

[0130] The target storage area includes a first area and a second area; the target information includes identification information, target parameters and an interface address.

[0131] It should be noted that the first area and the second area are different storage areas.

[0132] In the embodiment of the present application, the target parameters required for calling the interface of the target server and the return value address of the interface can be obtained from the second area according to the determined second address.

[0133] Step 304: The server verifies the target information.

[0134] In the embodiment of the present application, after determining the target information, the target information can be sent to the target interface through the target interface. Figure 4 The general processing layer in the target information can obtain the identification information of the interface, the target parameters corresponding to the interface and the return value address of the interface according to the target address in the target information, and then the legitimacy of the obtained data can be checked.

[0135] In one achievable manner, the representation information, target parameters, and return value addresses of the interface may be checked by a cyclic redundancy check (CRC) to ensure the integrity, accuracy, and security of the information.

[0136] It should be noted that step 305 or step 306 may be executed after step 304.

[0137] Step 305: If the target information is verified, the server sends the target information and the operation request to the client of the distributed file system through the target interface.

[0138] In an embodiment of the present application, if the validity check of the target information passes, the target information and the operation request can be sent to the interface of the client of the distributed file system through the target interface to call the interface of the client of the distributed file system to perform the target operation.

[0139] Step 306: If the target information verification fails, the server sends a verification result indicating the target information verification failure to the client.

[0140] In an embodiment of the present application, if the target information fails the legality check, it means that the server cannot send the target information to the distributed file system. At this time, the server can generate information carrying the verification result of the target information verification failure and feedback the information to the client.

[0141] Step 307: The client of the distributed file system receives the operation request for the distributed file system and the target information corresponding to the target operation sent by the server through the target interface of the client.

[0142] It should be noted that step 308 or steps 309 to 311 may be executed after step 307 .

[0143] Step 308: If it is determined that the operation request can be processed, the client of the distributed file system executes the target action corresponding to the target operation based on the target information, and sends feedback information for the target operation to the server.

[0144] In an embodiment of the present application, the client of the distributed file system can obtain the operation type of the target operation from the message carried in the operation request. If the operation type of the target operation is a read operation, the client can determine whether the metadata to be obtained exists in the consistency cache. If it is determined that the metadata to be obtained exists in the consistency cache, the metadata can be directly read from the consistency cache according to the target information, and feedback information carrying the read metadata is sent to the server through the target interface of the client.

[0145] In an embodiment of the present application, if the operation type of the target operation is a write operation, the client of the distributed file system can determine whether the metadata to be written has been written in the distributed file system. If the metadata already exists in the client of the distributed file system, or the metadata already exists in the server of the distributed file system, feedback information indicating that the metadata already exists can be sent to the server; correspondingly, if the metadata to be written does not exist in the client of the distributed file system, the corresponding metadata can be directly created according to the target information. If the creation is successful, feedback information indicating the successful creation can be sent to the server. If the creation fails, feedback information indicating the failure of the creation will be sent to the server.

[0146] Step 309: If it is determined that the operation request cannot be processed, the client of the distributed file system generates a target aggregation request based on the operation request and the target information.

[0147] In the embodiment of the present application, the inability to process the operation request may refer to the inability to process part of the operation request, or may refer to the inability to process all the requests in the operation request.

[0148] In the embodiment of the present application, if the operation type of the target operation is a read operation, and the client of the distributed file system determines that part of the metadata to be read exists in the consistent cache, then the client of the distributed file system will send part of the metadata in the cache to the server through the target interface, and encode and aggregate the part of the request and target information that cannot be processed in the operation request to obtain a target request for the target server of the distributed file system. It should be noted that the target request can be used to read metadata from the target server that is not read in the client.

[0149] Accordingly, if the client of the distributed file system determines that the metadata to be obtained does not exist in the consistent cache, the client of the distributed file system can directly encode the operation request and the target information to generate a target aggregation request for the target server. At this time, the target request is used to read all the metadata to be obtained from the target server.

[0150] In an embodiment of the present application, if the operation type of the target operation is a write operation, then if the client of the distributed file system determines that the metadata to be written does not exist in the consistent cache and the server of the distributed file system, the client of the distributed file system will also encode and aggregate the operation request and target information to obtain a target aggregation request for writing metadata in the distributed file system.

[0151] It should be noted that the target aggregation request may refer to a metadata server (MetaData Server, MDS) request of a distributed file system.

[0152] In an embodiment of the present application, by aggregating the operation request and target information, generating a target aggregation request and sending it to the target server, the target server can return all the metadata required by the user at one time, or create all the metadata that needs to be created at one time, thereby reducing the time delay in the writing / reading process, thereby improving the efficiency of metadata writing / reading, and at the same time, improving the performance of the user's access to distributed storage.

[0153] Step 310: The client of the distributed file system sends a target aggregation request to the target interface of the target server of the distributed file system through the target interface of the client, so that the target server responds to the target aggregation request and performs a target action.

[0154] The target node includes the client and the target server of the distributed file system. It should be noted that there can be one or more target servers.

[0155] In an embodiment of the present application, if the operation type of the target operation is a read operation, a target aggregation request can be sent to the target interface of the target server through the target interface of the client. After receiving the target aggregation request, the target interface of the target server can determine whether the required metadata exists in its own storage area. If so, the required metadata is directly returned.

[0156] In an embodiment of the present application, if the operation type of the target operation is a write operation, a target aggregation request for writing data can be sent to the target interface of the target server through the target interface of the client, and after receiving the target aggregation request, the target interface of the target server can create all the metadata to be written at one time.

[0157] Step 311: The client of the distributed file system receives feedback information regarding the target operation sent by the target server, and sends the feedback information to the server.

[0158] In an embodiment of the present application, if the operation type of the target operation is a read operation, and the target server successfully reads the required metadata, then the target server can send feedback information carrying the required metadata to the client of the distributed file system; correspondingly, if only part of the metadata is read, feedback information carrying part of the metadata can be sent to the client of the distributed file system; correspondingly, if the required metadata is not read at all, feedback information indicating a read failure is directly sent to the client of the distributed file system, and after receiving the feedback information from the target server, the client will directly feed back the feedback information to the user end.

[0159] In an embodiment of the present application, if the operation type of the target operation is a write operation, and the target server successfully creates the required metadata, the target server can directly send feedback information indicating the successful write to the client of the distributed file system; if the metadata creation fails, feedback information indicating the write failure can be directly sent to the client of the distributed file system; if only part of the metadata is successfully created, the target server can send feedback information indicating the successful write of part of the metadata to the client of the distributed file system. After receiving the feedback information from the target server, the client will directly feed back the feedback information to the user end.

[0160] Step 312: The server receives feedback information regarding the target operation sent by the target node, and sends the feedback information to the user end.

[0161] In an embodiment of the present application, if the target operation is a write operation, the target node will create corresponding metadata in its own storage area based on the received write operation request, and send the metadata creation result to the server in the feedback information. After receiving the feedback information, the server will directly feed back the feedback information to the user end.

[0162] In the embodiment of the present application, if the target operation is a read operation, step 312 can be implemented through steps 312a-312b.

[0163] Step 312a: If the target operation is a read operation, the server receives aggregated data for the read operation sent by the target node.

[0164] The aggregated data is obtained after the target node aggregates multiple data involved in the read operation.

[0165] In an embodiment of the present application, if the target operation is a read operation, the target node will obtain the required metadata from its own storage area based on the received read operation request, and then aggregate all the metadata to obtain aggregated data, and then return the obtained aggregated data directly to the server.

[0166] Step 312b: The server sends feedback information carrying aggregated data to the user end.

[0167] In an embodiment of the present application, after receiving the aggregated data sent by the target node, it is determined whether the aggregated data contains all the metadata required by the user end. If it is determined that all the required metadata is contained, all the metadata is carried in the feedback information and sent to the user end; however, if the aggregated data only carries part of the metadata, the part of the metadata and feedback information indicating the failure of the read operation are carried to the user end.

[0168] In an embodiment of the present application, the distributed file system aggregates all metadata required by the user end and feeds it back to the server at one time, which is then sent to the user end by the server. In this way, the user can obtain all the required metadata at one time, rather than having to call the distributed file system multiple times to obtain all the metadata. This not only reduces the time delay in the metadata reading process, improves the metadata reading efficiency, but also improves the user experience of accessing distributed storage.

[0169] The information processing method provided in the embodiment of the present application can receive an operation request for a distributed file system, and aggregate information of all interfaces involved in the distributed file system when performing a target operation as target information, and then based on the target information, call the distributed file system through the target interface to perform the target operation, that is, when the distributed file system performs the target operation, it only needs to call the distributed file system once, instead of calling the distributed file system multiple times as in the related art, which solves the problem of high time delay when performing a read operation or a write operation on the distributed file system in the related art, thereby improving the efficiency of reading or writing metadata.
