sijie opened a new pull request #1025: Issue 1024: Message Router should take `numPartitions` as parameter in choosing partition
URL: https://github.com/apache/incubator-pulsar/pull/1025
 
 
   ### Motivation
   
   currently message router doesn't expose number partition. it is hard for customized message router to get such information. It would be good to expose this information in message router.
   
   ### Modifications
   
   - introduce `TopicMetadata`
   - use `TopicMetadata` in message router for choosing partitions
   
   ### Result
   
   - deprecate the old `choosePartition` method
   - add test cases for all the message routers
