Subject limit of values in reduce phase?
Date Tue, 22 Jun 2010 00:14:55 GMT
I was just wondering the other day:

What if the the values for a key that get passed into the reducer do
not fit into memory?
After all a reducer should get all values per key from the whole job.
Is the iterator disk backed?
