Low-Latency and Scalable Full-path Indexing Metadata Service for Distributed File Systems

Distributed file systems (DFS) are the cornerstone of modern mass data processing systems. In DFS, the metadata service, as the core component, often becomes a performance bottleneck. Existing metadata service solutions have implemented flattened metadata management and full-path indexing to achieve high scalability in terms of capacity and throughput. However, these approaches have limitations, s…
