Foundationdb has ACID transactions over the entire db, over the cluster and over multiple keys. And fast. I've looked over so many open sources alternatives, and they claim ACID but it's a deception based on some narrow interpretation of ACID. It's very annoying to spend time researching to discover the truth between the lines. I would love to find a fast, scalable open source db that implements Foundationdb's features.
