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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
