Marcelo Vanzin commented on SPARK-5124:
---------------------------------------
bq. Reply to A but need a reply. It means, the replied message should be sent
to receiveAndReply method of A. (replyWithSender)
What's an actual use case here? Why can't this be handled by two RPCs: caller
-> callee and then callee -> caller, without the need for this separate reply
method?

> provide the foundation to try other RPC implementations in the future.
