Hello,

I'm running an ECK 2.6.1 elastic cluster in a non-prod k8s cluster which has a Horizontal Node Autoscale rule based on CPU+RAM metrics.  
Is it possible to shutdown elastic nodes on Friday night and start them back up on Monday morning ? By doing so the autoscaler kicks in and downsize the k8s cluster and thus the invoice for the resources which elastic eats up will be lower ?

Why I don't want to spin up another weekly cluster is the fact that I lose data gathered previously. With VMs this is simple to achieve.

I'm not sure if this is the best way to achieve your goal, but in theory, you could create 2 Kubernetes [cronjobs](https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/), one that runs on Friday nights, and one on Monday mornings. Each job could run something like `kubectl patch` or `kustomize` to update the `ElasticsearchAutoscaler` resource to meet your desired scales for weekends.
