# Optional — wipe the TPC-DS Parquet cache (re-creating it is cheap, but
# this frees ~5 GB on the minikube PVC)
kubectl delete pvc tpcds-data shuffle-data -n default --ignore-not-found

# Stop minikube (safe — your cluster state is preserved on disk)
minikube stop

# Or completely wipe the cluster
# minikube delete
