I think Aerospike has a very similar featureset. It is ACID + NoSQL, replicates nicely across multiple data centers, and definitely has a similar/better latency and throughput profile than FoundationDB.
ACID on a single "record". I am glad they document this openly, so many other DBs try to make it seem like they support ACID transactions in general.
From my understanding with FoundationDB, you did something of the form of "begin transaction" "do lots of stuff" "end transaction", and it just worked. I've yet to find another option that can do this.
