-- Lists information about the 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.
--
-- This operation returns paginated results.
