----------------------------------------
Leveldb is using 2MB by default. Real problem is naive leveldb implementation
in cassandra.
> Evaluate default LCS sstable size

> What we're not sure about is the effect on compaction efficiency --
> larger files mean that each level contains more data, so reads will
> have to touch less sstables, but we're also compacting less unchanged
> data when we merge forward.
> So the question is, how big can we make the sstables to get the benefits of
> the
> first effect, before the second effect starts to dominate?
