I have implemented all the suggestions you made. The only thing remaining
for this is:
- decide if keyBy is needed or not for the case when sorting happens only
on proc time (i would say it is needed to make it fully equivalent with an
actual sorting that would be implemented)
- refactor the datasetsort to use the common classes from sortutil (can be
done in a follow up request after the merge)
- implement the other 2 cases from the jira issue based on event time to
offer full sort support without retraction (for feature freeze)
