  title: Amazon Lake Formation Rotate Resource Data Access Role
  summary: Swap the IAM data access role on a registered data lake location by deregistering and re-registering it.
  description: >-
    Lake Formation does not expose an in-place update for a registered
    location's data access role, so rotating the role is modeled as a
    deregister-then-register sequence. The workflow describes the current
    registration to capture the existing role, deregisters the location, and
    re-registers it with the new IAM role, finishing with a describe to confirm
    the new role is in effect. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
