Subject Re: Tombstones and memtable_operations
Date Tue, 19 Apr 2011 16:21:53 GMT
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?

Thanks
