Shubham Chopra updated PIG-161:
-------------------------------
Attachment: pogenerate.patch
The new POGenerate with test cases attached.
I have tried to implement changes Alan suggested by not wrapping data in tuples
and bags and trying to have a template for the output tuple. I have used an
array instead of a Tuple for the template. I think writing to the final output
tuple straight away would need some overhead in keeping a track of the sizes of
the flattened tuples. So instead I put the final values in the array and
flatten it out (wherever flattening is needed) into a tuple. There is no
creation of any intermediate databags or tuples to wrap the data.
I have also tried to explain what I am trying to do in getNext(). Pls. suggest
if further elaboration is needed.
