  title: Amazon Keyspaces Decommission Keyspace
  summary: Delete a table, wait for it to drain, then delete its keyspace.
  description: >-
    Ordered teardown for Amazon Keyspaces. Because deleting a keyspace also
    deletes its tables, this workflow performs a controlled decommission of a
    single named table first: it deletes the table, polls GetTable until the
    service reports the table is gone (GetTable returns 400 once the table no
    longer exists), and only then deletes the parent keyspace. Amazon Keyspaces
    uses the AWS JSON 1.0 wire protocol, so the delete steps inline the
    documented X-Amz-Target header. The underlying OpenAPI description declares
    no request body schemas, so the delete payload fields follow the canonical
    AWS Keyspaces request contract.

      Poll the table until it no longer exists. While the table is still
      reported as DELETING with a 200 the step loops back on itself; once
      GetTable returns 400 the table is gone and the flow proceeds to delete the
      keyspace.
