I've worked on a deployment that uses them heavily and would be impacted by their removal. They are a very convenient place to put code that should run based on Nova events but I have yet to see a usage that couldn't have been implemented by having a service listen to notifications and run that same code. However there is no service that does this. So the only argument I can see for keeping them is that it's more convenient to put that code into Nova rather than implement something that listens for notifications. And that's not a convincing argument to me. So I agree with moving forward on deprecation and think that notifications provide a suitable replacement for the functionality provided. > > --Dan > > __________________________________________________________________________ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: > openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
