Impact on deprecation of BulkUpdateHandler on SDB

[Holger Knublauch]

SDB currently implements its own BulkUpdateHandler, and I just made some 
tests that indicate that it is significantly faster than using 
GraphUtil.add (2 seconds versus 40 seconds for 10k triples). Now that 
BulkUpdateHandler has been deprecated, and Model.add is already using 
GraphUtil.add, what call sequence are we supposed to use to retain the 
good performance of the BulkUpdateHandler? Could a method 
Graph.add(Iterable<Triple>) be added to allow graphs to optimize the 
behavior for specific Graph types?

Thanks
