> Suggested model: a producer owns one filter and resets its value, never its identity. The initial intention was to give an ability to reuse an existing physical plan. This model allows to do it, however each`.execute(...)` must be called strictly after `reset_plan_state` and, hence, after the previous stream is exhausted. To execute the same query in parallel, we need to create a physical plan N times for it. It seems acceptable to me. It would be cool to reflect this in a doc. > If you are no longer working on this, would it be OK to mark it help wanted with these steps? Yes, I am surely cannot return to this the next 2 weeks, so it is OK to mark it help wanted. -- This is an automated message from the Apache Git Service.
