[jira] [Created] (AURORA-730) Performance regression in fetching HostAttributes while scheduling

Bill Farner created AURORA-730:
----------------------------------

             Summary: Performance regression in fetching HostAttributes while scheduling
                 Key: AURORA-730
                 URL: https://issues.apache.org/jira/browse/AURORA-730
             Project: Aurora
          Issue Type: Bug
          Components: Scheduler
            Reporter: Bill Farner
            Assignee: Bill Farner
            Priority: Critical


Since switching to the database-backed store for host attributes, fetches have become considerably slower.  We anticipated this to a degree, but until we are fully switched to database stores and can remove the global read/write lock, throughput noticeably suffers in large clusters.
