Tsz-wo Sze commented on RATIS-979:
----------------------------------
Ultimately, we want the topology looks like a pipeline, i.e.
{code}
client ---> node0 ---> node1 ---> node2,
{code}
as described in Step 2 in the doc.
The advantages of pipelines are:
# Each node has at most an outbound and at most an inbound network traffic.
# It can minimise the cross rack traffic.
If we use the client to send data to each node, the client has a higher network
bandwidth requirement and it cannot optimise the network traffic.
Is there a particular use case in you mind?
