(it is a part of PR1788) solve the issue?
I think so.
I'm -1 adding various `non-equi join` to linq4j API provided they add no value.
I think the proper implementation should support "less than" kind of joins.
However, I doubt that implementation is possible with `Predicate` style
condition.
So adding Predicate argument does not leave room for future improvements.
