Not all ACID transactions are equal. This is just a key-value store-like test. It shows the potential to scale, yet nothing regarding performance in real word.

32 c3.2xlarge instances have 1920GB memory. Given 1 billion 16B+ 8..100B values the whole dataset fits just into memory.
The Cassandra test mentioned [1] sustained loss of 1/3 instances. That's very impressive! Would love to see how F-DB handles this type of real-life situation (hint hint for follow up blog post).
