Minimum memory usage requirements

Hello.

I am evaluating CockroachDB to use in my personal K8s cluster and I have installed it using the helm chart using the default values in Minikube.

I noticed the memory usage for 3-pods is around 700 MB without any load. (according to admin ui) Is this an expected value and there is a way to reduce this?

What would be the bare minimum required memory for Cockroach to function?

I would love to give Cockroach a try since its distibuted nature fits very well on Kubernetes but I want to keep the costs as low as possible since it´s a personal cluster.

Thank you.
