FILE ACCESS METHOD, APPARTUS, MEDIUM, AND DEVICE FOR DISTRIBUTED CACHE SYSTEM

Abstract

A file access method for a distributed cache system, an apparatus, a medium, and a device are provided. The method includes: reading metadata information of a target file from a first service node of the target file in response to an access request for the target file, wherein the metadata information is used to indicate a cache path of the target file, the first service node of the target file is any client node in the distributed cache system, a plurality of client nodes in the distributed cache system are respectively used as first service nodes of different files, and one first service node is used to maintain metadata information of at least one file; and accessing a second service node which is used to cache the target file according to the metadata information, and reading the target file from the second service node, wherein the second service node is any client node in the distributed cache system. In this way, it is possible to avoid centrally maintaining the metadata information of all files on the metadata server, but to disperse and store the metadata information of different files in different first service nodes, thereby avoiding the metadata server from becoming a performance bottleneck of the distributed cache system.
