+ <title>Sorting Data</title>
+ <p>
+ Pig allows you to sort data by ascending (ASC) or descending (DESC) order (for more information, see <a href="piglatin_ref2.html#ORDER">ORDER</a>). Currently, Zebra supports tables that are sorted in ascending order. Zebra does not support tables that are sorted in descending order; if Zebra encounters a table to be stored that is sorted in descending order, Zebra will issue a warning and store the table as an unsorted table.</p>
