> Change SortDataRows into an External Sorter, it should sort in memory until it reach configured size, then spill to disk. It should provide following interface:
> 1. addRow:  insert rows into the sorter.
> 2. getIterator: will return an iterator that iterates on sorted rows, the sorted row could come from memory or files
