Abstract or Description

Conventional file systems are optimzed for large file transfers instead of workloads that are dominated by metadata and small file accesses. This paper examines using techniques adopted from NoSQLdatabases to manage file system metadata and small files, which feature high rates of change and efficient out-of-core data representation. A FUSE file system prototype was built by storing file systemmetadata and small files into a modern key-value store: LevelDB. We demonstrate that such techniques can improve the performance of modern local file systems in Linux for workloads dominated by metadata and tiny files.
