Related to #69
Note: as mentioned in #69, by using the leader's vote, we could allow the log entries to be appended asynchronously and once finished add the vote to the request table.
One small thing, I would have preferred that applying the entry is done after we return the future in
setAsync
, but I didn't see any facilities for this. I know some Raft implementations will sometimes decouple the state machine and the Raft itself in different execution contexts, such that applying is also done asynchronously; this has some other issues (i.e. buffering apply calls), but could be an approach.
