Abstract

The invention discloses a file handle distribution method, device and equipment for a distributed storage system and a computer readable storage medium, and the method comprises the steps: judging whether a file handle corresponding to a user request exists or not according to the user request sent by a client; if yes, IO processing is carried out on the user request based on the file handle; if not, judging whether the total number of the currently allocated file handles reaches a preset threshold value or not; if yes, adding the user request to a waiting queue for waiting; if not, distributing a file handle to the user request so as to perform IO processing on the user request based on the file handle; according to the method, the distribution of the file handles can be better completed through the distribution mechanism, and the file read-write concurrence number can be better controlled by controlling the concurrence number of the file handles, so that the file read-write performance is improved, and the concurrence performance of the distributed storage system is improved.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, and in particular, to a file handle allocation method, apparatus, and device of a distributed storage system, and a computer-readable storage medium. Background technique [0002] Petroleum exploration refers to the use of various exploration methods to understand the underground geological conditions in order to find and identify oil and gas resources. With the rapid development of computers, networks, and storage technologies, the current petroleum geophysical Cross-combination of distributed storage and other technologies, through filtering, stacking, migration and other data processing of seismic wave data, using modern computer technology to generate and detect subterranean geological structures, combined with geological theory of oil generation, oil storage, oil and gas migration, accumulation, Preservation and other conditions, determine favorable areas for oil and gas ...
