   > @AlanConfluent Given that retry-on-empty-result is an existing behavior, 
maybe it is OK to check in the code as is. We can do a quick follow up FLIP to 
improve the behavior. Please let me know if you have time for this. I can find 
someone from LinkedIn to help if you don't have time. Thanks.
   
   I have some time budget to follow up with this.  I think your suggestions 
are good and it would be nice to make this more flexible.  I'm happy to do a 
followup FLIP covering this and it might make sense to cover async scalar as 
well.  In that case, there is always one result, but it could be null.  I think 
the current code actually allows null, so I'm not sure that the empty response 
check is ever triggered for async scalar, but maybe it should be.  Or maybe it 
makes less sense for the scalar case?
   
   Tell me what you think.
   
   Either way, happy to merge the code in this state and do an immediate follow 
up FLIP for empty case.
