Tsz-wo Sze commented on RATIS-759:
----------------------------------

> Do we also need to add handling for LeaderNotReadyException in function "exception2RaftClientReply"? 

Yes, it is a good idea, although the original code does not have it.

> It is inefficient to send a large message using send(Message)/sendAsync(Message) in RaftClient.  We already have RaftOutputStream implemented with sendAsync(..).  We propose adding the following new APIs
> {code}
>   /** Create a stream to send a large message. */
>   MessageOutputStream stream();
>   /** Send the given message using a stream. */
>   CompletableFuture<RaftClientReply> streamAsync(Message message);
> {code}
