   Yes, but you seem to provide an example of "as-is" too simplified. If we have 5 partitions for topicA, it would be:
   
   `{"topicA":{"0": 1000, "1": 1000, "2": 1000, "3": 1000, "4": 1000}}`
   
   and let's say topicA has 100 partitions... no, never mind.
   (I agree no one would deal with this by hand if number of partitions goes really big.)
   
   It also brings another advantage: we no longer need to know about number of partitions per topic in prior.
