[jira] [Created] (KUDU-2581) Reject the scan request if it has reached the num or memory threshold

Hexin created KUDU-2581:
---------------------------

             Summary: Reject the scan request if it has reached the num or memory threshold
                 Key: KUDU-2581
                 URL: https://issues.apache.org/jira/browse/KUDU-2581
             Project: Kudu
          Issue Type: New Feature
          Components: tserver
    Affects Versions: NA
            Reporter: Hexin
             Fix For: NA


Sometimes we have a lot of scan, which maybe causes the soft memory limit. We plan to achieve a method that rejecting the scan request if it has reached the soft memory limit or the scanner num has reached the threshold. The threshold is estimated by the actual memory of the system running the kudu.
