> Currently, we bail out in the metadata provider if join operator is not of
> inner type. For left, right outer joins, we could track expressions generated
> from columns from the left, right inputs, respectively. In addition, if any
> of the columns in the join cannot be backtracked, we could still backtrack
> the origin of an expression if it is not using that column, and currently we
> bail out too.
