bq. Yes, we should start changing Streaming to use network topology. It actually should not be very hard. We may pass a routing table in the RaftConfiguration.
bq. 
bq.   interface RoutingTable {
bq.     List<RaftPeerId> getForwardPeers(RaftPeerId primary, RaftPeerId current);
bq.   }
bq. Then, each peer can use it to forward the requests.

[~szetszwo] Hi, I'm thinking wheter we need to pass a routing table in the RaftConfiguration.

In ozone case, in my thinking.
1. when client wants to write data, scm can answer to client with 3 datanodes in order such as dn1-> dn2 -> dn3 to client
2. when create stream, client send this order to dn1, dn1 send this order to dn2, dn2 send this order to dn3.
3. then client send data to dn1, dn1 send data to dn2, dn2 send data to dn3.
