> It would be nice to have support for outer joins on DataStream. DataSet supports all
the outer joins (left, right, full) but DataStream only provides the inner join. 
> It has been pointed out that an outer join can be achieved with a coGroup, but I am of
the opinion that having first-class support for outer joins would be nicer.
