An Efficient Metadata Management Method in Large Distributed Storage Systems

摘要

Efficient metadata management is a critical aspect of overall system performance in large distributed storage systems. Directory subtree partitioning and traditional hashing are two common techniques used for managing metadata in such systems, but both have some shortcomings, for example, in directory subtree partitioning method, the root node easily becomes a bottleneck, and for traditional hashing, a large directory hierarchy must be maintained and traversed. In this paper, we present a new method called directory-level-based metadata management that has high efficiency while avoiding the shortcomings of traditional methods.
