we are running the official k8s helm chart are wondering why there is no HPA support for the
client node group?
We are aware that it would not be a good idea on the data / master nodes and that the clients also maintain some state, but in our experiments an (externally defined) HPA seems to work fine there.
Maybe we are missing some cases or scenarios where this could break?
PS: we know about the k8s operator, but don't want to switch right now.
