Agreed on this point. Many a times there is heavy lifting - recommendations, machines learning etc. However that is don't using specialized technologies in a non user facing process and the results are then dumped into a DB available for a CRUD app. I am hoping that products with such requirements will have some obvious tools for such tasks (Hadoop, Hive etc) and they would find a way to scale such processes with time. So their stack might be go+*sql+Hadoop. Can you please suggest some use-cases which don't fit the above pattern and maybe we can brainstorm. Seems like a fun exercise!
