      Description

      What we're not sure about is the effect on compaction efficiency –
      larger files mean that each level contains more data, so reads will
      have to touch less sstables, but we're also compacting less unchanged
      data when we merge forward.

      So the question is, how big can we make the sstables to get the benefits of the
      first effect, before the second effect starts to dominate?
