>
> At the moment, also non-equi joins are translated into {{DataSetJoin}}s.
> To prevent such plans from being picked, we assign huge costs and eventually
> fail their translation into DataSet programs.
> A better solution is to prevent a non-equi join from being translated into a
> {{DataSetJoin}} in the {{DataSetJoinRule}}.
