Grant Henke updated KUDU-2617:
------------------------------
Target Version/s: (was: 1.9.0)
> Don't flush an MRS if the DRS would have a larger memory footprint
> ------------------------------------------------------------------
>
> Key: KUDU-2617
> URL: https://issues.apache.org/jira/browse/KUDU-2617
> Project: Kudu
> Issue Type: Improvement
> Affects Versions: 1.8.0
> Reporter: William Berkeley
> Assignee: William Berkeley
> Priority: Major
>
> If a tablet server is under memory pressure and flushing small rowsets very
> aggressively, it might flush an MRS so small that the memory footprint of the
> resulting DRS (CFileReaders, LBM metadata, etc.) is larger than the MRS it
> replaced, defeating the purpose of the flush. We should have a sanity check
> to prevent this feedback loop.
