For what it's worth VoltDB uses main memory format as its "naive" approach to persistance too. I would consider VoltDB naive in the approach to persistance because it gives you dramatic gains (2 orders of magnitude) in read/write performance for similar workloads only by redefining concurrency and durability out of the equation. Durability is no longer a property of each machine but is instead a property of the network. Concurrency is handled by executing queries fast and doing them in series. So it's like ACID without the C or D.
