Processing method, system, device and medium for file reading and writing business

Abstract

The invention discloses a processing method for file reading and writing services, comprising the following steps: in response to receiving the file reading and writing services, judging whether there is a cache handle of the file in the index container according to the serial number of the file; in response to the absence of the file in the index container Open the corresponding handle of the file according to the read and write business; encapsulate the flag and pointer of the corresponding handle and the file serial number to obtain the cache handle of the file; add the cache handle of the file to the index container and the first queue; use the file The corresponding handle of the file is used to process the read and write business; in response to the completion of the read and write business processing, the cache handle of the file is moved from the first queue to the second queue. The invention also discloses a system, computer equipment and readable storage medium. The solution proposed by the embodiment of the present invention effectively reduces the pressure and frequency of file handle processing when the distributed file system reads and writes.

Description

technical field [0001] The invention relates to the field of storage, in particular to a processing method, system, device and storage medium for file reading and writing services. Background technique [0002] For the distributed file system (object storage), when the HDFS protocol is accessed, because it is a stateless access (the client will not send open and close requests to the storage end like the standard posix protocol), the distributed file system receives and reads each time When requesting, the file handle needs to be opened to realize the read and write business, and then the file handle is closed after completion. This will cause a large number of requests to open and close the file handle, which will cause a lot of load on the system and increase the delay of each read and write IO. Contents of the invention [0003] In view of this, in order to overcome at least one aspect of the above problems, an embodiment of the present invention proposes a method for p...
