Hi Folks, I was giving an Apex demo the other day and people asked following questions:
1) what is the communication protocol between operators when they are on distant nodes. That means, how does Apex transport the tuples from one node to the other? Is it a custom protocol on top of TCP/IP or is it RPC? 2) What is the serialization algorithm used? 3) What is the addressing scheme between operators? That means how does Apex know where an operator is located and how to route data to it? Is there an operator registry? If so, where does it reside? Thoughts? Thanks, Max.
