Could you provide some details on what types your multiple keys are and what expression variants you tried and what the result was ? The base class of BoundedDedupOperator is AbstractDeduper; within that class you'll see an method getKey(); you should be able to override that to retrieve the desired fields, combine them in some domain specific way, and return the result as a Slice.
