Hi openstack-discuss,
I’m currently using Rally v3.4.0 to test our OpenStack Zed platform.
Rally has been deployed on a dedicated virtual machine and Rally tasks and Tempest tests, launched on this machine by Rundeck, run pretty well.
Now, I wish every OpenStack team member could launch whatever scenario or test he wants, when he wants, for example after having applied a service configuration change on the staging platform.
And a question is arising: can several users launch different Rally scenarios or Tempest tests at the same time, from their own Linux account/environment, using the same Rally, the one which is deployed on the dedicated machine ?
Rally Task framework itself does not have limitations for parallel executions. But it is worth considering a few nuances: - Database backend. Rally is configured to use SQLite by default. It does not support simultaneous write operations, which can be an issue for using a dedicated rally instance for running parallel tasks. Switching to MySQL/Postgres should not have such an issue. - File descriptions. If you run too many parallel tasks with a huge number of parallel iterations, you may face default linux limitation of open file descriptors. I never ran Tempest simultaneously for the same cloud, so I cannot guarantee that there are no bugs, but it should be ok in general.
Thanks and best regards,
Jean-Francois
