  title: Amazon RDS Reboot a DB Instance
  summary: Reboot a DB instance with optional failover and poll until it recovers.
  description: >-
    Reboots a DB instance to apply pending changes or force a Multi-AZ failover,
    then waits for the database to return to service. The workflow confirms the
    instance is available, issues the reboot, and polls DescribeDBInstances until
    the status returns to available, looping while the instance is still
    rebooting. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.

  summary: Reboot a DB instance and wait for it to return to available.
  description: >-
    Confirms the instance is available, reboots it (optionally forcing a
    failover), then polls until DescribeDBInstances reports the instance
    available again.

      Describe the DB instance and inspect its status. While the instance is

      available the flow ends.
