    Description

      Long compactions currently drop cache behind reads/writes 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 minor compactions too.
