--------------------------------------

             Summary: Master's /stateSummary spends a lot of time coalescing ranges.
                 Key: MESOS-9297
                 URL: https://issues.apache.org/jira/browse/MESOS-9297
             Project: Mesos
          Issue Type: Improvement
          Components: master
            Reporter: Benjamin Mahler
         Attachments: mesos-master_scale_test_1001.stacks.gz, state_summary.png, state_summary_zoom.png

In a scale test, the /stateSummary endpoint was actually costing as much as the /state endpoint. I'm not sure how the request rate compared, but I noticed that /stateSummary spends a lot of time coalescing ranges, which seems unnecessary.
