Hi all, I want to make it easy to launch a bunch of scheduler processes on a host, multiple scheduler workers will make use of multiple processors of host and enhance the performance of nova-scheduler. I had registered a blueprint and commit a patch to implement it. https://blueprints.launchpad.net/nova/+spec/scheduler-multiple-workers-support This patch had applied in our performance environment and pass some test cases, like: concurrent booting multiple instances, currently we didn't find inconsistent issue. IMO, nova-scheduler should been scaled horizontally on easily way, the multiple workers should been supported as an out of box feature. Please feel free to discuss this feature, thanks.
