Generally, the write amplification will be < 7 (max # of levels), but in practice is probably ~3.5 since it's possible for files/keys to get promoted across mul

Generally, the write amplification will be < 7 (max # of levels), but in practice is probably ~3.5 since it's possible for files/keys to get promoted across multiple levels under some circumstances. I haven't measured specifically what you asked for, but have watched the compaction system quite closely in heavy production loads. :)
