I don't know what your project is, but Etcd is excellent for this sort of thing if your project is distributed and you need resilience, and you can live with the external dependency on its daemons. Etcd is also a hierarchical database, but you can use it like a robust distributed file system. A big benefit you get is liveness; you can respond dynamically to config changes by watching for change events.
