Jonathan Coveney commented on PIG-2353:
---------------------------------------
So Gianmarco, are you thinking this sort of syntax:
{code}
A = <some relation>
B = RANK A BY <column name> <ASC | DESC>;
{code}
IE it'd just follow the order syntax, but add the rank to the end?
And I assume your n map job would run after already sorting the, right? So
first rank would run the order by, and then it would run the two jobs that
would actually append the rank?
> RANK function like in SQL
