[~krummas] cool, I think it's a more easy-to-understand idea, and maybe could save a lot of code. Here is the patch https://github.com/DikangGu/cassandra/commit/3dfd0f29c9152bbe5283514f6f90886ebc2f87f1, can you please take a look?
I'm not sure how to write the unit test at this moment, will try some manual testing.

> Level compaction does not persist the last compacted key per level. This is important for higher levels.
> The sstables with higher token and in higher levels wont get a chance to compact as the last compacted key will get reset after a restart.
