Ah, I'm glad you brought this up - there was a bug with the initial rocksdb_cf_compact_on_deletion implementation where it wouldn't take effect for the default column family; this has been corrected only recently, and the bug is still present in Pacific. You'll need to reshard in order for the setting to work. Resharding can also help with reducing compaction load a bit, but I don't think it'll help much with tombstones.
