Subject Re: leveled compaction and tombstoned data

@ben, thx, we will be deploying 2.2.1 of DSE soon and will try to
setup a traffic sampling node so we can test leveled compaction.

we essentially keep a rolling window of data written once.  it is
written, then after N days it is deleted, so it seems that leveled
compaction should help
