The Netfrastructure uses it, right ? I'm really curious about the impact
of this approach. Well, I expect that it's lightning fast compared to FB,
but how you keep it reliable (hw/sw failure proof) under massive load ? I
suppose that there is a lot of internal bookkeeping to save everything on
commit, but how you manage that to make it reliable in case of failure in
the middle ?
