Issue description
We have a job dependencies sample which illustrates an ad-hoc way of executing acyclic graphs of dependent jobs.

We propose to make this an actual feature instead of a sample, and to explore other possibilities such as:
  • a broader set of relationshups between jobs than just "depends on", e.g. split/join (or map/reduce). This implies to be able to gather global results for an entire job and apply transformations to these results.
  • an expressive and intuitive way to build the job graph
