Grant Henke updated KUDU-18:
----------------------------
Target Version/s: 1.8.0 (was: 1.5.0)
> Handle "slow readers" not holding too much memory
> -------------------------------------------------
>
> Key: KUDU-18
> URL: https://issues.apache.org/jira/browse/KUDU-18
> Project: Kudu
> Issue Type: Improvement
> Components: tablet
> Affects Versions: M3
> Reporter: Todd Lipcon
> Priority: Major
>
> Currently if a scanner is held open, it can hold on to resources from the
> tablet indefinitely. This includes memory resources like
> MemRowSet/DeltaMemStore which can be quite large. We should figure out a way
> to forceably expire slow scanners or otherwise migrate them to the flushed
> copies.
