Dear Nova notification consumers! The Nova team made progress with the new versioned notification interface [1] and it is almost reached feature parity [2] with the legacy, unversioned one. So Nova team will discuss on the upcoming PTG the deprecation of the legacy interface. There is a list of projects (we know of) consuming the legacy interface and we would like to know if any of these projects plan to switch over to the new interface in the foreseeable future so we can make a well informed decision about the deprecation. * Searchlight [3] - it is in maintenance mode so I guess the answer is no * Designate [4] * Telemetry [5] * Mistral [6] * Blazar [7] * Watcher [8] - it seems Watcher uses both legacy and versioned nova notifications * Masakari - I'm not sure Masakari depends on nova notifications or not Cheers, gibi [1] https://docs.openstack.org/nova/latest/reference/notifications.html [2] http://burndown.peermore.com/nova-notification/ [3] https://github.com/openstack/searchlight/blob/master/searchlight/elasticsearch/plugins/nova/notification_handler.py [4] https://github.com/openstack/designate/blob/master/designate/notification_handler/nova.py [5] https://github.com/openstack/ceilometer/blob/master/ceilometer/pipeline/data/event_definitions.yaml#L2 [6] https://github.com/openstack/mistral/blob/master/etc/event_definitions.yml.sample#L2 [7] https://github.com/openstack/blazar/blob/5526ed1f9b74d23b5881a5f73b70776ba9732da4/doc/source/user/compute-host-monitor.rst [8] https://github.com/openstack/watcher/blob/master/watcher/decision_engine/model/notification/nova.py#L335
