   > IIUC, the TopicMetadata gives us the number of partitions at the time the MessageRouter is invoked. For our use case, we need to keep recording the number of partitions when a new partition key is defined.
   
   I'm not convinced exposing `NumPartitions()` would help here. All the custom logic should be possible to implement within a custom message router. 
   
   In any case, there's already a way to get the partitions for a topic, by using `Client.TopicPartitions()`
