> 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. -- This is an automated message from the Apache Git Service.
