Whether you want to build the software, run it, grow the community or just learn more about it, there will be content, workshops and design sessions for you to attend at the OpenStack Summit, Oct 15-18 in San Diego. Stick around Friday for the first OpenStack service day, a 1/2 day beach cleanup.
Currently nova compute nodes periodically write to the database (every 10 seconds by default) to report their liveness. The Servce Group API factors out this functionality and make it a set of abstract internal APIs with a pluggable backend implementation. We'll discuss the traditional DB based backend and the ZooKeeper backend, and whether this is more suitable to openstack-common so that other projects may adopt them too, and the related blocking issues.
