> Sometimes we have an unbalanced clusters and it is difficult to know whether some nodes are taking more space because updated have not yet been compacted away or it is due to distribution of data.
> So we need to know the true fully compacted data size. 
> We can do this with validation compaction and summing up the size of all rows. 
> We should also emit such a sum during repair when the Merkle tree is being generated.
