HQebupt opened a new pull request #13239: URL: https://github.com/apache/pulsar/pull/13239
### Motivation PartitionedProducerImpl should public the number of partitions of its topic. Although we can get the number partitions of a topic by calling the pulsar client's RPC, this will consume one RPC request. - Topic partition may change, which causes me to call RPC to get it when I need to know the number of partitions. Producer can always get the number of Topic partitions because it has TopicsPartitionChangedListener. Therefore, the public API can improve performance, which is worthwhile. When you use Producer to send, you also want to know the number of topic partitions. This was indeed used when I designed and implemented MQ on Pulsar, which improved the performance of Proxy and increased throughput. ### Modifications ### Verifying this change - [x] Make sure that the change passes the CI checks.
