Cache Management System for Enhancing the Accessibility of Small Files in Distributed File System

摘要

The present invention relates to a cache management system for improving accessibility to a small file in a distributed file system, and more particularly, to a cache management system in which a name node for storing chunk metadata and cache metadata of a file stored in a data node, And one or more data nodes comprising a data node local disk for maintaining a chunk and a client local disk holding a client cache and chunk for storing the small file, the chunk metadata and the cache metadata, And a server node for interfacing with the HDFS and storing and managing a plurality of events in the HDFS so that the HDFS can use the small files efficiently, Improve It can minimize network load.
