             Summary: Figure out retention policy for scheduler job update data
                 Key: AURORA-743
                 URL: https://issues.apache.org/jira/browse/AURORA-743
             Project: Aurora
          Issue Type: Story
          Components: Scheduler
            Reporter: Maxim Khutornenko


We need to come up with job update history retention policy sooner than later 
to avoid tipping over the snapshot creation timeout (large heap data == longer 
GC times == failover). Perhaps going after the Task retention approach (N items 
per job) is the easiest until we have a durable DB storage/backups and can 
afford longer history (e.g. time-based purging or infinite archive).
