One side question from me -- I think it would be good to understand
more about recommended etcd set-ups at different scales of k8s cluster
(10, 50, 150, 500+ nodes) and how to deal with n/w partitions.

There are many variables on how much workload an API server puts on etcd but there is a ballpark guess doc here:

https://etcd.io/docs/v3.4.0/op-guide/hardware/
This is great, I don't know how I missed it before. QQ: Are your
example configs each using only one VM per cluster? That is not
totally clear from the docs.


What do you mean by dealing with network partitions? Does the failure guide section on network partitions help? https://etcd.io/docs/v3.4.0/op-guide/failures/
Thank-you. I've seen this --- I guess what I am asking about is
practical guidance on how often to expect different types of network
failures, and what to expect, how long etc. I understand this is hard
to do in a general manner.
