Again with this?Yes, I was reiterating that we should not talk about a specific choice but continue with the other discussion. Tooz, ZooKeeper, Consul, etc, is all irrelevant to the rest of the conversation we are having. The specific technology used can be discussed in an x-project spec, but I really would rather see a very opinionated choice. That can again be delayed until a later point.We already what we want to get out of Tooz, where we want it and for how long we'll be using it in each of those places.My response was also before the rest of the convo that occurred post Flavio's summary.To answer those questions all that's needed is to read this thread and the links referred on some conversations.I am fine with using a DLM. I see a significant benefit (without putting too fine a point on it, Keystone *will* benefit from a choice for a DLM to be available in OpenStack, and I like the idea). I was hoping to continue (and we did) identify where we had DLM-like/DLM uses in OpenStack so we knew where to focus.Hey all, This thread is a mess. I'm going to put together facts with what projects are doing and why. I will present my findings at the session that I will be moderating in the cross project track of the summit [1], if accepted. Spec may follow. [1] - https://etherpad.openstack.org/p/mitaka-cross-project-session-planning
FWIW, there are 2 threads now. This one that you just replied to is supposed to be related to Cinder and not to the cross-project discussion. It's a mess, I agree! :( That said, you may want to sync with Joshua since he's going to work on a cross-project spec as well (as he mentioned in the other thread).[0] Thanks for taking the time, Flavio [0] http://lists.openstack.org/pipermail/openstack-dev/2015-August/071400.html
