Joe Smith updated AURORA-117: ----------------------------- Labels: O1 (was: O2) > Scheduler performance issues with very large jobs > ------------------------------------------------- > > Key: AURORA-117 > URL: https://issues.apache.org/jira/browse/AURORA-117 > Project: Aurora > Issue Type: Task > Components: Reliability, Scheduler > Reporter: Bill Farner > Labels: O1 > > The scheduler tends to have performance issues when scheduling very large > jobs. We've observed this with jobs exceeding 2000 instances. The > {{TaskScheduler}} thread tends to consume a large amount of CPU (100%, > limited by the global storage lock). Current hypothesis is that the majority > of the time is spent satisfying diversity constraints (rack, machine), which > require expensive queries. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
