> Commit log archiving and replay can be used to support point in time restores on a cluster.
Unfortunately, at the moment that is only true when the topology of the cluster is exactly
the same as when the commitlogs were archived. This is because commitlogs need to be replayed
on a node that is a replica for those writes.
> To support replaying commitlogs when the topology has changed we should have a tool that
replays the writes in a commitlog as if they were writes from a client and will get coordinated
to the correct replicas.
