> Issue Type: Improvement
> Components: Compaction
> Reporter: Ashu Pachauri

>
> Long compactions currently drop cache behind reads so that they don't pollute
> the page cache but short compactions don't do that. The bulk of the data is
> actually read during minor compactions instead of major compactions, and
> thrashes the page cache since it's mostly not needed.
> We should drop page cache behind reads for minor compactions too.
