> BTreeSearchIterator - 2.65% of allocations within 
> org.apache.cassandra.db.rows.AbstractRow#hasLiveData
> We can use BTreeRow#minLocalDeletionTime to avoid iteration over cells in 
> some scenarios, like: if (minLocalDeletionTime == Cell.MAX_DELETION_TIME)
>          return !BTree.isEmpty(btree);
