MarĂ­a GH commented on BEAM-2286:
--------------------------------

I encountered the same issues described. Although, 1. is an understatement!--my 
Linux machine completely froze for 10 minutes when using the default input. 
While the default input gets changed, a note should be added to the 
documentation:

Smaller datasets run without any problems

> Few things I noticed while running mobile gaming example that could be 
> improved:
> 1. When running on direct runner the default input is too large (20G), so it 
> seems as though the pipeline is stuck without an progress updates or metrics.
> This could be improved by using a much smaller dataset by default.
> 2. Even when running on dataflow runner, with default worker settings and 
> auto scaling, it still takes more than 30 minutes to run. We could use a much 
> smaller dataset here too. 
> Also the documentation of these examples could be improved in both the code 
> docstring as well as beam quick start guide.
