1. case class AppendEntries[T](term: Term, leaderId: NodeId, prevLogIndex: LogIndex, prevLogTerm: Term, entries: List[LogEntry[T]], leaderCommit: LogIndex) extends RaftRequest with Product with Serializable

   
   term

   our (the leader's) term

   leaderId

   our (the leader's) id

   prevLogIndex

   the last known (or assumed) index as we know it. If the reciever replies w/ a non-success response, this index is decremented and retried

   prevLogTerm

   our previous log term

   entries

   the entries to append ... which are only non-empty if a previous AppendEntries request came back successfully

   leaderCommit

   our latest commit index

5. trait ClusterProtocol extends AnyRef

   

   Represents a view of the clusterto a RaftNode.

   Represents a view of the clusterto a RaftNode. This is passed in, allowing the RaftNode (whos responsibility is to maintain its own state) to communicate with the rest of the cluster and control its timeouts
