> Ozone, in replicated mode writes the data twice, once to the raft log and
> then to the statemachine.
> This results in the data being written twice during a particular chunk write,
> this is subobtimal. With RATIS-122 the statemachine in Ozone can be optimized
> by writing the data to the statemachine only once.
