Turn the logging up to DEBUG, if you want to you can do it just for
org.apache.cassandra.service.StorageProxy , and look for…
* forwarding counter update of key… when the coordinator is forwarding the
counter update
* insert writing local & replicate… when a counter mutation is applied locally
Thanks! This would make sense but I'm not sure it maps to what I'm seeing.
Specifically if I start processes that write to each of the three nodes, so
I know there is a constant stream of writes to each node, instead of seeing
replicate on write on all nodes, I see it only on a single node.
It app
I've not checked the code but from memory when the nodes are ordered in
proximity to the coordinator the local node is always first if it's in the
replica set. So with RF=3 and N=3 the closest node is always the local one.

@a
I'm writing at QUORUM though and (pardon me for being dense) it would seem
that the first replica shouldn't always be on the same server if I'm using
RP.
I very much appreciate your time, I'm sure there is something basic that
just hasn't clicked.

I don't think so, perhaps more succinctly, why would ROW actions only be
performed on a single node?

are you i/o bound? I believe counter ROW needs to perform a read of
the old value.
