--- deprecations: - | The ``RetryFilter`` is deprecated and will be removed in an upcoming release. Since the 17.0.0 (Queens) release, the scheduler has provided alternate hosts for rescheduling so the scheduler does not need to be called during a reschedule which makes the ``RetryFilter`` useless. See the `Return Alternate Hosts`_ spec for details. .. _Return Alternate Hosts: https://specs.openstack.org/openstack/nova-specs/specs/queens/implemented/return-alternate-hosts.html
