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.
