yjshen opened a new pull request #5788: [pulsar-java-client] Decouple partition switch frequency with maxPublishDelay in producer configuration
URL: https://github.com/apache/pulsar/pull/5788
 
 
   # Motivation
   
   Currently, while using round-robin message router, messages would be route to different partitions at the `maxPublishDelay` boundaries. However, when GC occurs, the output partition would change frequently and results in small batches. 
   
   This PR introduces a conf field setting the round-robin partition switch frequency: `batchingPartitionSwitchFrequencyByPublishDelay`. With this PR, the partition switch interval could be set as `maxPublishDelay` * `frequency`.
   
   ### Modifications
   
   `batchingPartitionSwitchFrequencyByPublishDelay` in `ProducerConfiguratiionData.java`
   
   ### Verifying this change
   
   
   This change is already covered by existing tests.
   
   ### Does this pull request potentially affect one of the following parts:
     - The public API: (yes)
   
   ### Documentation
