commit 1d98f0a7d43bc45b66260053bde76d992fd613b8 Author: Kailun Qin <[email protected]> Date: Fri Jul 6 20:20:08 2018 +0800 Event driven periodic resync task for DHCP agents The DHCP agent will resync its state with Neutron to recover from any transient notification or RPC errors. Currently, the periodic resync task waits on a timer to determine whether a re-sync is necessary. The interval between attempts by default is 5 seconds and can be longer thru config. This may cause a potentially long delay before an agent gets new work via an agent_updated RPC call. The idea of this RFE is to change the timer based periodic resync task into an event driven one. It also proposes a new DHCP agent config option "resync_throttle" to ensure the minimum interval taken between resync state events to avoid too frequent resyncing. In this way, we could force the agent to act on the resync request immediately therefore decreasing how much time is needed before DHCP services are available.
