> Currently, Kafka emits the producer-byte-rate and fetch-bytes-rate for quota calculations. By adding a new signature to the `[quotaMetricTags|https://github.com/afshing/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/server/quota/ClientQuotaCallback.java#L40]` method to add the individual topic-partitions size as a parameter, we can define metrics based on the topic name and partition id. 
> To do that, we need both `ProduceRequest` and `FetchResponse` have the `partitionSizes` method and it is public.
