Re: [openstack-dev] [Rally] Question on periodic task
Hi Boris Looks like this would require changes in key portions of Rally infra. Need some more time getting a hang of rally by committing a few scenarios before I make infra changes Ajay From: Boris Pavlovic mailto:bo...@pavlovic.me>> Reply-To: "OpenStack Development Mailing List (not for usage questions)" mailto:openstack-dev@lists.openstack.org>> Date: Friday, November 21, 2014 at 7:02 AM To: "OpenStack Development Mailing List (not for usage questions)" mailto:openstack-dev@lists.openstack.org>> Subject: Re: [openstack-dev] [Rally] Question on periodic task Ajay, We have this in our RoadMap: https://github.com/stackforge/rally/blob/master/doc/feature_request/multi_scenarios_load_gen.rst So, it's not yet supported out of box, but we really would like to have it in upstream.
