   > We could infer from context (ex. `HashJoinExec` is always a producer), but 
then there's the question of custom `ExecutionPlan` implementations. I figured 
we'd want them to declare themselves to be producers or consumers.
   
   Exactly. There is a draft PR in Ballista to add a custom hash join operator 
(with spilling). We would want DataFusion to treat it as a HashJoinExec even 
though it is a custom implementation.
