Title:
Minimize agent state reports handling on server side
Status in neutron:
Expired
Bug description:
Agent state reports are mostly needed in order for neutron server to properly
(re)schedule resources among agents.
New features may require more precise scheduling which in turn requires
agents to report more and servers to handle more data.
However adding new logic to agent state reports handling has negative
effect on scalability and overall neutron server performance. Here is
one of examples: https://bugs.launchpad.net/neutron/+bug/1567497 with
more cases possibly coming in future: like
https://review.openstack.org/#/c/285548 which is adding a new db
update request for each state report.
One of the things that could be done is to not include (or just to ignore on
server side) the data which can't be changed during runtime (like config
parameters) in each state report. Such data should only be processed on agent
(re)start/revival.
So mainly it's about separating static and dynamic data in state reports
handling to reduce the amount of db updates.
