> h3. Motivation
> A topology-aware RAFT client can subscribe to the leader appearance. It is a
> way to know when a RAFT group is ready to apply any command. Currently we can
> create the client over the logical topology, but in some cases we have to
> know about group availability before the logical topology is formed (for CMG).
> h3. Implementation notes
> It is possible to implement it in one class if we have the base interface for
> both topology listeners (LogicalTopologyEventListener and
> TopologyEventHandler).
> h3. Definition of done
> Topology-aware RAFT clients can rely on physical or logical topology.
