> We can consider adding metrics for process / punctuate / commit rate at the granularity of each processor node in addition to the global rate mentioned above. This is very helpful in debugging.
> We can consider adding rate / total cumulated metrics for context.forward indicating how many records were forwarded downstream from this processor node as well. This is helpful in debugging.
> We can consider adding metrics for each stream partition's timestamp. This is helpful in debugging.
> Besides the latency metrics, we can also add throughput latency in terms of source records consumed.
