There is some mention on Twitter about using RocksDB for RDF storage.
It's an obvious route to investigate: RocksDB provides range scans and (soon) transactions.
Not new! Sneak preview of WIP: https://github.com/afs/tdb3 The "soon" is work by Adam Retter (many thanks!) and now a PR for RockDB. Andy This "make" compilation is a bit retro!
