Peter Bacsko updated YUNIKORN-3112:
-----------------------------------
Description:
Sending out events in every 15 seconds for unschedulable pods can results in a
performance degradation of etcd if the number of such pods are large.
Possible approaches:
* More aggressive rate limiting, eg. 5 minutes instead of 15 seconds
* Do not send an update at all if the event message is not changing
* Do not send large messages - just send the failed plugin instead of a long
diagnostic message (eg. "TaintToleration (4x)" instead of a longer "node(s) had
untolerated taint \{xyz: abc} (4x); failed plugin: 'TaintToleration'")
