> If raft server use Grpc, when append entries blocked at follower side (e.g.,
> by calling SimpleStateMachine4Testing::blockWriteStateMachineData), leader
> should still be able to send heartbeat (size of entries of append entries
> request be 0) to followers, and receive response of heartbeat from follower
> side, since we have the code
>
> {code:java}
> @Override
> public void onNext(REQUEST request) {
> if (!replyInOrder(request)) {
> try {
> process(request).thenAccept(this::handleReply);
> } catch (Throwable e) {
> handleError(e, request);
> }
> return;
> }
> final PendingServerRequest<REQUEST> current = new
> PendingServerRequest<>(request);
> final PendingServerRequest<REQUEST> previous =
> previousOnNext.getAndSet(current);
> final CompletableFuture<Void> previousFuture = Optional.ofNullable(previous)
> .map(PendingServerRequest::getFuture){code}
>
>
> But test case "testUpdateViaHeartbeat" shows that after calling
> SimpleStateMachine4Testing::blockWriteStateMachineData, leader do send
> heartbeats, but ServerRequestStreamObserver::onNext at
> GrpcServerProtocolService was not called, until follower finish handling the
> append entries request that blocked by blockWriteStateMachineData.
