The current recommendation for implementing SCD2 tables, at, suggest to first do a join with existing data, to get a list of rows that must be added. That seems somewhat wasteful - merge operation already does a join, do we're down to two joins. Are there any plans to make this more straightforwards, say by allowing a whenMatched to both update existing record and add a new one?
