Daniel Dai commented on PIG-1270:
---------------------------------
Thanks Min, that's encouraging. Which version of Hadoop are you using?
Also I discussed with Min in IM, it will be better to have a global flag to
signal the sufficiency of records, so that we can address more cases for this
optimization.

> We can optimize limit operation by stopping early in PigRecordReader. In
> general, we need a way to communicate between PigRecordReader and execution
> pipeline. POLimit could instruct PigRecordReader that we have already had
> enough records and stop feeding more data.
