We don't have any auto scaling for either up or down scaling, but if you're using a deployment tool such as Kubernetes, I don't see why it wouldn't be fairly easy. And it might be a good idea to add a message in the admin UI if you all of your nodes are experiencing a high load.

By just looking at your max load over the last 24h or perhaps week, it would be pretty easy to see when to down scale.

That being said, as long as you remove the cockroach nodes one at a time , it's pretty easy to down scale a cockroach cluster.
