Thanks for the info.

The documentation for  grpc::ServerAsyncReaderWriter< W, R >::Read says (
http://www.grpc.io/grpc/cpp/classgrpc_1_1_server_async_reader_writer.html#a2adbae40645434ad5f55823967998acc
) -

" It should not be called concurrently with other streaming APIs on the
same stream. "

So if a streaming write operation is allowed concurrently, this doc should
be updated?

And then on the same topic, if I have a read operation queued but meanwhile
the server decides to finish up (say an error/whatever), can I queue up a
Finish/FinishWithError call? Or is the correct usage there is to call
TryCancel on the server context with an AsyncNotifyWhenDone call?

Thanks.
