Question regarding kubie ns

[Fobhep]

Hey - I have a question regarding the functionality of kubie ns and the validity check parameter.

I have a user that is allowed to read NS - however due to speed reasons I set validate_namespaces: false in hope that it would be faster then.

No when I type kubie ns I get the list of all namespaces offered and I wonder how kubie is doing that really.
Or rather - what exactly is kubie ns doing - if not get all namespaces and list them for me.

The odd thing is - the disabling seems to speed up the process definitely. Is an enabled validating ADDITIONALLY to getting the list of namespaces?

I think we can close this after the the great contribution from @gsstuart :)

Just for reference - I mitigated the problem for myself in between by writing two functions for my zshrc:

function kns-update-cache() {
  mkdir -p "$HOME/.kube/kubectx-cache"
  kubectl get ns -o json | jq -r ' .items[] | .metadata.name' > "$HOME/.kube/kubectx-cache/$(yq -r '.current-context' $KUBECONFIG | cut -d'/' -f2)"
}

function kns() {
  cat "$HOME/.kube/kubectx-cache/$(yq -r '.current-context' $KUBECONFIG |  cut -d'/' -f2)" | fzf |  xargs -L1 -I% yq e -i '.contexts[].context.namespace = "%"' $KUBECONFIG
}

That allow me to cache Namespaces and thus speed up the call as well
