IO task processing method, device and apparatusand readable storage medium

Abstract

The invention discloses an IO task processing method, device and apparatus and a readable storage medium. The IO task processing method comprises the steps of obtaining an IO task sent by a client; determining a first file descriptor corresponding to the IO task; determining a target of the IO task in the tgt service according to the first file descriptor; using an epoll thread bound with the target target for processing the IO task; wherein, only the epoll thread bound with the target target is used for processing the current IO task; that is to say, one IO task is only processed by one epollthread, so that the lock application is avoided, the lock application time is saved, the IO task processing time can be saved, and IO task processing efficiency and server processing capability are improved. Correspondingly, the IO task processing device and equipment and the readable storage medium disclosed by the invention also have the above technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an IO task processing method, device, equipment and readable storage medium. Background technique [0002] In the prior art, in order to improve the ability of the server to process IO tasks, one IO task can be assigned to multiple epoll threads for processing. However, when multiple epoll threads process an IO task at the same time, the same data may be involved. Therefore, in order to avoid processing errors, it is necessary to lock the repeatedly involved data. It is necessary to apply for a lock before locking the data. When a certain data is being processed by a certain epoll thread, other epoll threads will not be able to apply for the lock, so the lock application will take up more time. Moreover, different stages of the processing flow of an IO task require multiple lock applications, which will reduce the processing efficiency of the IO task and the processi...

It is necessary to apply for a lock before locking the data. When a certain data is being processed by a certain epoll thread, other epoll threads will not be able to apply for the lock, so the lock application will take up more time

Moreover, different stages of the processing flow of an IO task require multiple lock applications, which will reduce the processing efficiency of the IO task and the processing capacity of the server.
