> When an aligned checkpoint barrier arrives in an input channel, we should enqueue at the head of the queue priority event, announcing arrival of the checkpoint barrier.
> Such announcement event should be propagated to the `CheckpointBarrierHandler`. Based on that, `CheckpointBarrierHandler` will be able to implement logic of time outing from aligned checkpoint to unaligned checkpoint.
