Description

Small potential improvement:

We could communicate the last completed checkpoint, which will serve as basis for future incremental checkpoints, through the trigger checkpoint message for that checkpoint, i.e. the trigger determines the base checkpoint for the next increment. This would be slightly more reliable than going through the CheckpointListener mechanism, which is not guaranteed the deliver its message.
