Start Delay metric is always zero for unaligned checkpoints

    XMLWordPrintableJSON

    Details

      Description

      As visible in the attached screenshot, start delay is 0, despite very high end to end time and very quick async/sync times. This is impossible, as "start delay" should be equal to "end_to_end_time - sync_time - async_time".

      The bug is probably in CheckpointBarrierUnaligner class, which seems to never invoke CheckpointBarrierHandler#markCheckpointStart.

      It's important to make sure this metric is also set for source tasks (time to acquire checkpoint lock).
