> Persistant volumes rely on NFS (or a flavor thereof), which is not great for database performance.

NFS is an option, but it’s not the only option. If you need locally attached storage you can use local PV’s which went GA in Kubernetes 1.14, or any of the plethora of volume plugins that exist for various network storage solutions.

Network storage, NFS or other, is never optimal for DB storage. It can and is used, but it’s never going to be as good as local storage.

I had forgotten about local storage; it’s not something we can use in our environment.

It’s a moot point, in either case. Vitess doesn’t rely on persistent storage, it relies on replicas and backups.
