> **`project` applies the monotonic fallback to non-final range keys, where the disjointness check does not hold** > > Partition membership for a multi-key `Range` is a lexicographic comparison of the whole tuple, but the disjointness check only proves something about one key. That gap is reachable. read through this and yes, can confirm that this is possible and correctness bug. We could get duplicate group rows or partial sums as final results. I also agree with @jayzhan211 suggested approach for a solution thank you @jayzhan211 🙇 -- This is an automated message from the Apache Git Service.
