Shashikant Banerjee commented on RATIS-759:
-------------------------------------------
Thanks [~ljain], i think unless the stream is closed, we don't have the issue
here. The leader just holds up to the messages until the stream is closed, it
will create a ratis transaction only once the close is executed. Even if the
leader changes in between, the closing of the stream will fail with
NotLeaderException.
> Support stream APIs to send large messages

> 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}
