Description

File operation processing method and device Technical Field The present invention relates to the field of distributed file processing technologies, and in particular, to a method and an apparatus for processing a file operation. Background In a distributed file system, there are multiple operations for a file, such as a read-write operation, a truncate operation, etc., and in a practical scenario, the same file often receives multiple different types of operation requests at the same time (e.g., a write request and a truncate request are received at the same time). The existing method generally utilizes the metadata service node to receive the interception requests, maintains and records specific interception data corresponding to each interception request, and simultaneously, the client needs to additionally carry interception information in order to prevent newly written data from being intercepted or read stale data when initiating the read-write request. Disclosure of Invention In view of the above, the embodiment of the invention provides a file operation processing method and device, which are applied to a file operation processing system, and can utilize a processing server to receive a read-write operation request for a target file sent by a client and to receive a cut-off operation request for the target file sent by an information server forwarding client, determine the concurrent operation sequence of the read-write operation and the cut-off operation, execute the read-write operation and the cut-off operation based on the concurrent operation sequence, and further send first feedback information corresponding to the cut-off operation and second operation feedback information corresponding to the read-write operation. In order to achieve the above object, according to one aspect of the embodiments of the present invention, there is provided a file operation processing method applied to a file operation processing system, including a client, an information server, and a processing server; The processing server receives a read-write operation request for the target file sent by the client and receives a cut-off operation request for the target file sent by the information server forwarding client; The processing server determines the concurrent operation sequence of the read-write operation and the cut-off operation, and executes the read-write operation and the cut-off operation based on the concurrent operation sequence; The processing server sends first feedback information corresponding to the cut-off operation to the information server, so that the information server forwards the first feedback information to the client after determining that the first feedback information sent by all the processing servers is received, and the processing server sends second operation feedback information corresponding to the read-write operation to the client. Optionally, the processing server acquires the read-write operation request and the target data block indicated by the cut-off operation request, and indicates the read-write operation state or the cut-off operation state by using the state identification of the target data block in the process of executing the read-write operation and the cut-off operation. Optionally, after receiving the request of the information server for intercepting the target file sent by the client, the processing server sets the state identifier of the target data block to be in an intercepting operation state and feeds back first feedback information indicating that the intercepting operation is successful to the information server, and after receiving the request of the client for reading and writing the target file sent by the client, the processing server sets the state identifier of the target data block to be in a reading and writing operation state and feeds back second feedback information indicating that the reading and writing operation is successful to the client. The processing server judges the state identification of the target data block after receiving the request of the information server forwarding the interception operation of the target file sent by the client, determines that the concurrent operation sequence of the reading and writing operation and the interception operation is the prior operation of the writing operation when the state identification is determined to be indicated as the writing operation state, and determines that the concurrent operation sequence of the reading and writing operation and the interception operation is the prior operation of the interception operation when the state identification is determined to be indicated as the interception operation state, and the writing operation or the reading operation is the subsequent operation when the state identification is determined to be indicated as the interception operation state. Optionally, for the case that the concurrent operation sequence of the read-write operation and the cut-o
