Ok, I've read about gc grace seconds, but i'm not sure I understand it fully. Untill gc grace seconds have passed, and there is a compaction, the tombstones live in memory? I have to delete 100 million rows and my insert rate is very low, so I don't have a lot of compactions. What should I do in this case? Lower the major compaction threshold and memtable_operations to some very low number?
