> For large messages, to load the entire payload into memory might be bad because the payload might be bigger than the max memory available. It would be useful to have an API which allows for use of input and output streams, so that large payloads can be read iteratively by a user and streamed out to the cluster via the underlying channel breaking the data in the input stream into chunks, which are fed into the input stream on the receivers side.
> Issues: we have to have 1 input stream per sender on the receiver side, because a stream is always defined between 2 parties (sender, receiver). Maybe something like NIO, where we register interest in a stream, are notified of new streams ('accept()') and get notified when data on any of the stream is available, would be beneficial.
