Futurize transforms subpackage
URL: https://github.com/apache/beam/pull/5729#issuecomment-407102486
 
 
   I did not benchmark changes in c270644 yet, but doing bisection on previous 
version of the PRs shows that the largest contributor to regression is the line 
`from __future__ import division` in `util.py`. I still don't understand the 
reason why it causes the regression. One place where we may have missed to 
modify division is 
https://github.com/Fematich/beam/blob/c2706447a6a602614c2f9bf36db1a666fa938819/sdks/python/apache_beam/transforms/util.py#L277
 but changing division there to integer division does not seem to help. Looking 
further.
