libradosfs

libradosfs is a complete client-side implementation of filesystem-like functionality based on Ceph’s RADOS object store (implemented in C++).

libradosfs was designed according to the requirements of the former CERN Data Storage Services group in terms of scalability and flexibility: it provides a scale-out namespace and pseudo-hierarchical storage view, with optimized directory and file access (no strict POSIX semantics), parallel metadata queries, modification time propagation, file striping and other features.
