With my operator hat on, I would like to use the etcd backend, as I'm already paying the cost of maintaining etcd clusters as part of Kubernetes. Adding Zookeeper is a lot more work.

Currently devstack defaults to zookeeper and is opinionated about it.
Talking to Josh, etcd seems to be a good option too.
Does anyone have specific experience with etcd with tooz?
Do we want to make DLM mandatory? (always run with tooz + backend)?
Asking because lots of the container related projects are using etcd
, so we may want to avoid both zookeeper and etcd?
Thoughts please. Note that this came up during the Atlanta PTG as well 
PS: the dragonflow one looks really good!
