> 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.
