-----------------------------------------
Summary: Scheduler updater should suppress instance events on
resume
Key: AURORA-1097
URL: https://issues.apache.org/jira/browse/AURORA-1097
Project: Aurora
Issue Type: Task
Components: Scheduler
Reporter: Maxim Khutornenko
Scheduler updater does not attempt to suppress redundant instance events in
case an update is paused/blocked and is subsequently resumed/pulsed. This leads
to a useless sequence of no-op instance events, which may quickly consume the
allocated event cap (tracked in AURORA-1096).
For example, an update paused/resumed 2 times after instance 1 is updated will
generate the following instance sequence:
1=[INSTANCE_UPDATING, INSTANCE_UPDATED, INSTANCE_UPDATING, INSTANCE_UPDATED,
INSTANCE_UPDATING, INSTANCE_UPDATED]
