How does this compare with http://rethinkdb.com/ ?

RethinkDB doesn't support ACID transactions.

Yep, that's a big difference.

RethinkDB is also a document store, whereas FoundationDB is an ordered K/V store at its core (although transactions / layers allow for richer data modeling through stateless translation "layers").

I don't think there's any data on RethinkDB and Jepsen. Would be interesting to see someone do the work to make that happen.

It is worth noting that an ordered K/V store is a very simple and flexible data structure in terms of the types of operations that can be efficiently layered on top of it. The simplicity gives you guys a chance to do something insanely hard like distributed transactions. The flexibility lets people build a ton of different abstractions on top of it.
