> I see, unless source doesn't send `None`. It doesn't propagate above the execution. If you send it from the source, I think you will see the result at the end as a single bulk once `None` propagates. Thanks for your pacience, but I still can't get it. Do you mean that the window function executes incrementally, but only after receiving the `None` signal can it output all remaining results? If I understand correctly, why does PARTITION BY need to see all the data and Why the tokio task cancel? -- This is an automated message from the Apache Git Service.
