So just out of curiosity, but do people really even know what etcd is
good for? I am thinking that there should be some guidance from folks in
the community as to where etcd should be used and where it shouldn't
(otherwise we just all end up in a mess).
Perhaps a good idea to actually give examples of how it should be used,
how it shouldn't be used, what it offers, what it doesn't... Or at least
provide links for people to read up on this.
Thoughts?

One clarification: Since https://pypi.python.org/pypi/etcd3gw just
uses the HTTP API (/v3alpha) it will work under both eventlet and
non-eventlet environments.

Team,
Here's the update to the base services resolution from the TC:
https://governance.openstack.org/tc/reference/base-services.html
First request is to Distros, Packagers, Deployers, anyone who
installs/configures OpenStack:
Please make sure you have latest etcd 3.x available in your
environment for Services to use, Fedora already does, we need help in
making sure all distros and architectures are covered.
Any project who want to use etcd v3 API via grpc, please use:
https://pypi.python.org/pypi/etcd3 (works only for non-eventlet services)
Those that depend on eventlet, please use the etcd3 v3alpha HTTP API using:
https://pypi.python.org/pypi/etcd3gw
If you use tooz, there are 2 driver choices for you:
https://github.com/openstack/tooz/blob/master/setup.cfg#L29
https://github.com/openstack/tooz/blob/master/setup.cfg#L30
If you use oslo.cache, there is a driver for you:
https://github.com/openstack/oslo.cache/blob/master/setup.cfg#L33
Devstack installs etcd3 by default and points cinder to it:
http://git.openstack.org/cgit/openstack-dev/devstack/tree/lib/etcd3
http://git.openstack.org/cgit/openstack-dev/devstack/tree/lib/cinder#n356
Review in progress for keystone to use etcd3 for caching:
https://review.openstack.org/#/c/469621/
Doug is working on proposal(s) for oslo.config to store some
configuration in etcd3:
https://review.openstack.org/#/c/454897/
So, feel free to turn on / test with etcd3 and report issues.
Thanks,
Dims
