Subject [jira] [Commented] (AURORA-1472) TaskThrottle should have a configurable jitter
Date Fri, 25 Dec 2015 10:28:49 GMT


Tony Dong commented on AURORA-1472:

I probably went a little bit overboard in the code change.
I implemented the different backoff+jittering algorithms outlined here:
and also made the backoff strategy more guice friendly.

> As an Aurora cluster operator, I need the ability to configure a random jitter which
is added to the [throttle time of flapping jobs|].

> Background information: Due to some cascading failures, we ended in a state where many
instances where throttled. Unfortunately, all these instances were restarted at the exact
same time. This overloaded a backend used for package retrieval. A random jitter would have
helped us to spread out the load on the backend service.
