summary
Claims a graph-structured namespace that replaces hierarchical inodes with nodes and edges to capture directories, hard links and snapshots, implements compact adjacency lists and a lightweight graph index, and integrates with existing storage via a FUSE-based prototype called GramFS. Evaluation runs on a cluster-scale namespace with millions of entries and shows constant-time lookup for deep paths, dramatically faster metadata recovery after failure, and higher metadata operation throughput compared with tree-based systems.
