commit 255e8a839db0be10c98b5d9f480ce476e2f2e171 Author: Kevin Benton <[email protected]> Date: Thu Mar 31 05:03:12 2016 -0700 Turn nova notifier into a proper rate limiter This adjusts the batching logic in the Nova notifier to immediately send and then sleep to allow batching of subsequent calls in the batch interval. So rather than always wait for 2 seconds to elapse while batching, batching will only occur in the 2 second period after a call is made. This turns the batch notifier into a standard queuing rate limiter. The upside to this is a single port create results in an immediate notification to Nova without a delay. The downside is now that a sudden burst of 6 port creations to a previously idle server will result in 2 notification calls to Nova (1 for the first call and another for the other 5).

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1564648 Title: nova notifier should send first event immediately Status in neutron: Fix Released Bug description: The nova batch notifier currently waits to batch up events on every single notification. This means even in a quiet system, the batching mechanism will add a delay to every single notification to Nova. This extra 2 seconds (or whatever it is configured to) builds up over time and adds quite a bit of delay to tempest runs (2 seconds * number of booted VMs).
