We can leverage the 'retrying' module (already in global requirements).
It lacks a few things we need, but those can be implemented using its
existing "hooks" today, or, working with the module owner(s) to push a
few changes that we need (the later probably provides the "greatest good").
Assuming we'll leverage 'retrying', I was thinking the initial goals
(a) Ensure 'retrying' supports the behaviors we need for our usages in
neutron + nova (see  -  on my initial note) today. Implementation
(b) Implement a "Backing off RPC client" in oslo, inspired by .
(c) Update nova + neutron to use the "common implementation(s)" rather
This sounds fun and I'm happy to take it on. However, I probably won't
make much progress until after the summit for obvious reasons. I'll plan
to lead with code, if a RFE/spec/other is needed please let me know.
Additional comments welcomed.
