-- Displays detailed information about a specified virtual cluster. Virtual
-- cluster is a managed entity on Amazon EMR on EKS. You can create,
-- describe, list and delete virtual clusters. They do not consume any
-- additional resource in your system. A single virtual cluster maps to a
-- single Kubernetes namespace. Given this relationship, you can model
-- virtual clusters the same way you model Kubernetes namespaces to meet
-- your requirements.
