> I heard a lot that Cassandra uses 2MB slab allocation strategy for memtable to improve its memory efficiency. But in fact, it has been changed from 2MB to 1 MB.
> And in NativeAllocator, it's logarithmically from 8kb to 1mb.
> large number of tables may not cause too much trouble in term of memtable.
