> For debugging and development, it would be very useful to be able to print
> Kafka streams topologies. At a minimum, it would be great to be able to see
> the logical topology including with Kafka topics linked by sub-topologies. I
> think that this information does not depend on partitioning. For more
> detail, it would be great to be able to print the same logical topology but
> also showing number of tasks (an perhaps task ids?). Finally, it would be
> great to show the physical topology after the tasks have been mapped to JVMs
> + threads.
