>
> Currently we keep track of the progress of each consumer using checkpointing
> mechanism. These checkpoints are controlled by Samza, and the system consumer
> is not aware of it.
> But some systems may require knowledge of the current checkpointed position
> in the stream.
> For this purpose we propose an optional notification mechanism for input
> systems.
> See the attached doc for details.
