  title: Azure Databricks Terminate and Permanently Delete a Cluster
  summary: Terminate a cluster, wait until TERMINATED, then permanently delete it.
  description: >-
    Cleanly decommissions a cluster. The workflow terminates the cluster,
    polls the cluster get endpoint until its state is TERMINATED, and only then
    issues a permanent delete so the cluster configuration is fully removed.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
