So, what is the problem? What happens when we have an active system? Well, every time that we make a modification, we’ll add it to the log. That is all good and great, but what about the actual log? Well, it is going to stay there, we need it so we can catch up any new server that will join the cluster. But that means that over time, we are going to have an unbounded growth. Which isn’t a very nice thing to have. Rachis handle this by asking the state machine to implement snapshots.
