» GraphStorage

…is a Graph storage and query library based on Google LevelDB and written in C++.

It currently supports integer indexed nodes with properties and directed edges with types. The integer IDs are serialized by hand, values are serialized using protocol buffers. Everything is stored in a single sorted LevelDB database.

Queries are possible trough a iterator like interface that handles single level queries quite fast. Additionally changes to edges can be monitored using a subscription mechanism.

The library is in development and while not intended for any kind of production usage the source code is available via both Github and cgit.
