Jonathan Coveney commented on PIG-2353:
---------------------------------------
Is there anything in the piggybank using the e2e? I'm not sure what the word is
about piggybank and when to use e2e. Someone else will have to weigh in on that.
As far as that other JIRA...you should make it and link it, though I'm curious
what benefit/optimization you forsee RANK having if it has access to Pig's
internals.
> RANK function like in SQL
