Thanks for the efficient review @pnowojski ! >As far as I understand it, it's not a full fix, as EndOfPartitionEvents or checkpoint barrier cancellation markers can still cause the same race condition, and you want to fix it in a follow up PR, right? Exactly, it only resolves partial race condition in this PR, and i also thought these still has some issues while handing EOF and cancellation marker, which seems hard to reproduce in `UnalignedCheckpointITCase`. Furthermore, considering the current logic inside `CheckpointBarrierUnaligner` is too complicated, actually it is totally different with my initial PoC version. I try to refactor some logics to simplify the process a bit while resolving the other two issues, so i choose to resolve them separately to not delay the whole progress. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
