FaunaDB (mentioned in previous comment) -- it is multi-model NoSQL so you can do relational queries and it supports transactions across multiple partitions, documents, replicas. json docs, not tables.
Would be good to see -- problems/issues that needed code fixes? maybe caused you to rethink (or regret) implementation decisions? I'm sure Kyle's report will have something good. I always root for Jepsen...and I haven't been disappointed yet.
Jepsen is an important sanity check on marketing. Easy to say in collateral you are "strict" ACID -- Jepsen proves (or denies) those claims. Some fun reports over there http://jepsen.io/analyses
