      Description

      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.
