> In some applications, some servers in a raft group are more preferable to be the leader than the other servers.  For example, a server is colocated with other resources so that having the server as the leader is more efficient than the other servers.
> In this JIRA, we propose adding _priority_ to each server so that the higher priority server(s) will always win the leader election when they are available.
