JULEA is a flexible storage framework that allows offering arbitrary client interfaces to applications. To be able to rapidly prototype new approaches, it offers object and key-value backends that can either be client-side or server-side; backends for popular storage technologies such as POSIX, LevelDB and MongoDB have already been implemented.

Additionally, JULEA allows dynamically adapting the I/O operations' semantics and can thus be adjusted to different use-cases. It runs completely in user space, which eases development and debugging. Its goal is to provide a solid foundation for storage research and teaching.
