The Twizzler KVS (key-value store) is just 250 lines of C code, and uses one persistent object for the index structure, and a second one for the data. The paper concludes with a quick comparison of a KVS written using a modified FreeBSD kernel in the Twizzler-proposed model, and a traditional Unix implementation using files.
