-----------------------------
Affects Version/s: (was: NA)
1.8.0
> 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: 1.8.0
> Reporter: Hexin
> Priority: Major
>
> Sometimes we have a lot of scan, which may excess the soft memory limit. The
> greater the excess, the higher the chance of causing throttling for writing.
> We should 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 should be estimated by the actual memory of the system running the
> kudu. By this way，the system can provide more space for writing.
