Abstract In distributed storage systems, file access efficiency has an important impact
on the real-time nature of information forensics. As a popular approach to improve file
accessing efficiency, prefetching model can fetches data before it is needed according to
the file access pattern, which can reduce the I/O waiting time and increase the system
concurrency. However, prefetching model needs to mine the degree of association
between files to ensure the accuracy of prefetching. In the massive small file situation,
the sheer volume of files poses a challenge to the efficiency and accuracy of relevance
mining. In this paper, we propose a… More >
