rqlite[1] author here. Just to be clear, rqlite is not SQLite but rewritten in Go. rqlite uses the vanilla C code, and calls it from Go[2]. I consider that an important advantage over other approaches -- rqlite gets all the benefits of rock-solid[3] SQLite. As result there are no questions about the quality of the database engine.
