> Increment metric when Interval Join record is late

> Currently an interval join will silently drop late records. I think it would
> be quite useful to have the metric *numLateRecordsDropped* incremented when
> this happens. Window Join already does this, so it would make sense to have
> it happen for both types of joins.
